Hello everyone, this is Paleo Nerd here with the second part of my Jurassic Fight Club Analysis. In this video. I will be covering the second episode of Jurassic Fight Club, T. rex Hunter, Going over the designs of the dinosaurs and the fight itself to determine what is accurate and inaccurate about it. Spoilers. This one is pretty inaccurate. So brace yourselves. The second episode, T. rex Hunter, takes place 65 million years ago in what is now Montana and features a fight between two juvenile Tyrannosaurus rex and an adult Nanotyrannus. Now this episode has a lot of major inaccuracies, but first we’ll go over each dinosaur. From here on for I will go over each creature in the order they appear in the fight. So What is T. rex? Well, Tyrannosaurus Rex, or tyrant Lizard King, needs no real introduction as it’s widely known and is one of, if not the most well recognized dinosaur ever It was first discovered in 1874 from teeth However, it wasn’t long before more remains were discovered surprisingly Tyrannosaurus wasn’t the first name assigned to this animal, as fossils now classified as Tyrannosaurus have been given names like Manospondylus gigas meaning giant porous vertebrae, and Dynamosaurus imperiosus, meaning Imperial dynamic lizard. In fact, the famous name Tyrannosaurus Rex wasn’t given to the animal until 1905, over 30 years after the first fossils were discovered. Over the years since its discovery, much has been learned about T. rex, and it’s currently the non-avian dinosaur we know the most about. Tyrannosaurus is one of the last of a group of theropods called Tyrannosaurids, a group of coelurosaurian theropods that ruled the northern hemisphere for much of the Late Cretaceous Now, while it was widespread throughout Western North America, T-rex is most common in the famous Hell Creek Formation, and the multitude of remains have dated this species within a range of 68 to 66 million years ago, during the maastrichtian age of the Late Cretaceous, a surprisingly short reign for such a large predator. Unsurprisingly, T. rex was the apex predator of its environment, and at a max length of 12 meters or 40 feet a max height of 4 meters or 12 feet and a max weight of over 9 tons, T. rex is considered to be the largest terrestrial predator to ever exist Now, how does the Jurassic Fight Club version compare? Well surprisingly in terms of appearance,
the design is not very inaccurate, with only slight nitpicks like weird-looking feet, a head that doesn’t match the skull exactly, a Slightly shorter neck, and the typical pronated hands common in all theropods in film and TV. However, while the weight is accurate, they make the animal too large, putting its height as 15 to 20 feet and its length as 43 to 50 feet. This is wrong, as the largest dimensions T. rex reached based on the largest specimen Were 12 feet tall and 40 feet long, and again, this is the largest we know they grow. There is one other minor inaccuracy in regards to the skin. Recent skin impressions from T. rex has indicated that while it was indeed scaly These scales were pretty small and the skin would appear smooth at a distance similar to this scaleless lizard. Also, while this has yet to be proven with physical evidence, It has been proposed that T. rex may have had small filaments in addition to scales similar to that of elephant hair. Again, this is pretty minor, and this discovery was after the series aired so it gets a pass. Overall, not the most accurate design but ok. There are only two major inaccuracies with this version. First really isn’t with the design but this is really the best place to put it throughout the episode George puts forward Speculation that T. rex had an infectious bite like Komodo dragons via the use of deadly bacteria. While speculation is necessary when making a documentary about prehistoric creatures, this takes it too far, mainly because it’s based on inaccurate information. This is back when Komodo dragons were thought to kill their prey using deadly bacteria living in their mouths But later studies have found that they actually have venom glands and their lower jaws Which inject venom into their prey when they bite down. This toxin prevents blood from clotting And causes the prey to slowly bleed Now not only is there no evidence that T. rex had either deadly bacteria or venom glands, but T. rex and Komodo dragons are not closely related, as T. rex, like all dinosaurs are archosaurs, consisting of both avian and non-avian dinosaurs, pterosaurs, and crocodilians While Komodo dragons, as lizards, are squamates, a group of reptiles consisting of lizards and snakes, Only distantly related to archosaurs like crocodiles and dinosaurs, So the Komodo dragon really shouldn’t be used as a base for speculation for T. rex The other major inaccuracies is in the juvenile and we’ll address that one with this guy Nanotyrannus, oh boy. I need a real field day with this one So Nanotyrannus lancensis was a species of Albertosaurine Tyrannosaurid and was considered closely related to Albertosaurus and Gorgosaurus. In fact Nanotyrannus was originally classified as a species of Gorgosaurus. the name translates to dwarf tyrant from Lance, in reference to its small size at only 5 to 6 meters or 16 to 20 feet long and 2 meters are about seven feet tall, and the Lance Formation at which it was first found, another formation with many T. rex specimens. The most famous specimen from this former genus is Jane, a Near-complete specimen that ultimately helped pull the lid on the coffin to this genus. The thing is, Nanotyrannus is not a valid genus and all specimens classified in that genus are now considered to belong to juvenile specimens of Tyrannosaurus The series actually does address this but dismisses it arguing that Nanotyrannus is its own genus because as more teeth than adult Tyrannosaurus. While this may seem like a compelling argument, it gets rendered completely pointless By the discovery of a sub-adult T. rex which had more teeth than adult T. rexes but less teeth than Nanotyrannus, Thus proving that T. rex lost teeth as a matured Now we’re back to those juveniles I mentioned earlier in the show, They are shown to be miniature versions of their parents, which was just wrong. As proven by Jane and other former Nanotyrannus, T. rex underwent an interesting form of puberty, Starting out as thin and agile pursuit predator,s and eventually growing and changing into a bulky apex predator This is partially why T. rex is so interesting to me personally and why this particular Inaccuracy really gets at me. Because they have longer legs that are more adapted to long distance pursuits, Juvenile T. rexes are believed to have been very effective pursuit predators Easily hunting faster prey like ornithomimids, And it’s quite possible that juveniles were better predators than their parents. That being said the model itself has few if any inaccuracies just besides the typical pronated hands, the only real exception I can pick out is that juvenile Rexes likely had a somewhat thick coat of filaments, but Since there is no real physical evidence for this, it doesn’t count Overall the most ironic part about Jurassic Fight Club’s Nanotyrannus is that while they messed up big time by making it its own genus the design is the most accurate in the entire show, And for that I have to give this show a lot of credit not enough not enough to save it from all the other inaccuracies But enough to give respect towards a really accurate design Now, how about the fight? Well the fight starts off with two adult T. rexes, a male and a female leaving their nest to hunt for food. Now first off the two adults are the exact same size when we know that T. rex was very likely sexually dimorphic Within the almost 200 years we have been discovering t-rex specimens Paleontologists have determined two different types or morphs of Tyrannosaurus with minor differences indicating a difference in gender rather than in species There’s the grass aisle morph which is smaller and thinner in the robust morph which is larger or thicker For a long time the robust morph was considered to be the female while the grass aisle was thought to be the male this inspired the famous Queen Rex paleo meme present in many early 2000s documentaries like walking with dinosaurs and when dinosaurs roamed America Nowadays, this is considered to be wrong. And the male has now been proposed as the bigger gender But the truth is that we’ll likely never know for sure since it’s impossible to tell a fossil animals gender and since the show never specifies which parent is which They all they would have to do is make one parent slightly smaller and thinner than the other All those although this would require a new model which may not have been available on a TV show budget Another thing is it’s very likely that only one parent tended for the offspring Likely the female while the other would simply leave even if both parents raise the offspring They would likely just take turns hunting and guarding the young instead of constantly putting their children in danger when they go to hunt Next George helpfully explains to us that the parents have left a scent around their nesting area to ward off predators Which is something more along the lines of mammals and reptiles says reptiles lack scent glands in their anal region that mammals have we also see three dromaeosaurus using a recycled model of Deinonychus which features in the next episode these are likely dromaeosaurus geniuses dromaeosaurus About 70 million years ago Although there was thought to be a species from Hell Creek based on draw Fragments these turn out to belong to a new genus. Aquarelle Raptor Anyway, the acro raptor are repelled by the scent even though should be like a homing beacon to them indicating that there are some vulnerable juveniles nearby Thankfully an adult male nano tyrannous gets the right idea and walks right into the nesting area Gorge once again explains that nano tyrannous is basically the serial killer of dinosaurs Entering t-rex nests to kill their babies not for food but to eliminate competition This is completely wrong first we’ve already established an analyst our Juvenile T Rex’s and second the whole killing to eliminate competition thing Only very intelligent animals like humans and dolphins kill for fun and nano tyrannous /t rocks doesn’t really fit the criteria here T-rex also wouldn’t have served this competition for nano tyrannous slash juvenile T Rex’s as stated before gol T Rex’s were excellent pursue predators in as such hunting completely different prey from the adults while adult Rex’s ate large herbivores like Ed Montes Soros and Triceratops juveniles hunted smaller and faster, prey like orenthal – Pachycephalosaurus, and even the gigantic Anzu and since juveniles in the episode still rely on their parents for food They likely would have simply eaten their leftovers mean. They wouldn’t be eating anything that nano tyrannous would rely on for food finally, even if the nano tyrannous went through all the trouble they killed juvenile T Rex’s He most definitely would eat them. Otherwise, he would just be wasting a ton of energy killing things. He doesn’t even want to eat Anyway, the nano tyrannous walks right into the nest confronted two juveniles head-on keeping his distance at first wary Of their bacteria filled mouths, but which I’ve already explained why it’s wrong so I won’t go over it again George explains that this bacteria is the first biological weapon in nature. These are the first animals to use biological weapons when other animals like arachnid snakes lizards and even proto mammals called Theroux civilians use biological weapons like venom and poison long before tea rocks evolved The nano tyrannous then uses mock charges to split up the juveniles Causing one of them to lunge forward and lose his footing the needle grabs the juvenile and throws it across the ground It is Possible that nano tyrannous slash juvenile t-rex’s were strong to do this but centering how lightweight they are I wouldn’t bet on it the Nano then moves towards the other juvenile which cries for help now Normally this would cause any predators to walk away and find different prey but then an all being an idiot Decides to stay and try and kill the juvenile before the parents return Using its experience to its advantage the Nano shoves around the juvenile as its prey limits its movements Now the Nano should in what of just straight-up attacked is it likely would have easily killed the juvenile? But I guess they needed this fight to be longer Anyway, the Daniel Tyrannis is about to strike when the other juvenile bites him in the leg This takes him off and he kills the juvenile by snapping his neck with a strong bite and then stomping it to death again, nano slash young Rex’s likely didn’t have us have strong enough jaws to snap a neck like that and they wouldn’t Have weight enough to crush a skull just by stomping on them regardless The nano turns the other baby trying to kill it as quick as possible he knocks it over and as he reaches for the final blow he feels vibrations new ground in the mom returns Putting herself between her offspring in their attacker Now any sane predator would turn tail and run immediately after? But this 2l Tyrannis is apparently the dumbest animal to ever walk the earth because he tries to get around the mom and kill her, baby Nevertheless he fails in the mom crushes him in her enormous jaws She that drops the Nano to the ground and tears apart his corpse with her foot claws to use as a warning Now I have to question the moms parenting skills here When waving her young completely vulnerable of all hunting to only showing up in the last possible moment – leaving a torn up carcass that will most definitely attract predators I have 100% convinced. This t-rex is actively trying to kill her own children, and the male is nowhere to be seen Sure, the show claims that maternal Instincts meant that the female got there first, but we never ever see the male returned ever So now I’m convinced that the psychotic t-rex mother Murdered her on me. And now she’s trying to kill her kids – too bad Child Protective Services didn’t exist during the Cretaceous period Overall this episode completely falls apart with all the inaccuracies from the designs to the premise itself There are some other inaccuracies that only serve to further tear this episode apart, for example The juvenile t-rex is should no longer be under their parents care in the first place This show seems to imply that t-rex is raise their young until doll hood when in reality Rex’s likely only cared for their young for two to three years at the most at which they could take care of themselves There’s also the fact that like cannibal dinosaur this episode way Overestimates how much dinosaurs actually cared for their young? Yes, maternal bonds can be very strong in mammals Dinosaurs are not mammals. If a baby dies. They just eat it and make some more Finally the last nail on the coffin Many of the measurements are way higher than they would actually be likely to look more impressive Nanotyrannus has shown to be much stronger than an animal that size and build would be and way faster to T-rex in the show is stated to run 30 to 40 miles per hour When the max speed it could run at before its bones broke under their own weight would be 12 miles per hour Nano is said to be even faster at 40 to 50 miles per hour When the fastest juvenile t-rex would have run at would have likely been about 20 miles per hour at the most This may seem slow but predators only need to be slightly faster than their prey For what which for t-rex tends to be pretty slow and juvenile Rex’s preening animals only slightly faster than that So in conclusion, if you’re looking to learn anything, you might as well skip this episode And there’s besides the design of nano tyrannous Nothing portrayed in this episode is accurate I think covered the major stuff Because if I went on with this it would be an hour long and I still eat more episodes to go over How to make it better well since there’s so many inaccuracies Here the changes to make this episode accurate will basically mean Making a completely new episode to replace it So this next part is just my opinion on what would make a good replacement while still keeping t-rex First of all make the a no Tyrannis of juvenile Rex. This should be obvious Second focus exclusively on juvenile t-rex is and have no adults in the fight at all This choice would serve mainly to put more spotlights on the juveniles capability as a predator in its own merit Remember t-rex started hunting on their own at 3 years old They were pretty darn good at it Now much of its prey doesn’t put up much of a fight other than running and there are way too many predator Prey flights in this show already. So let’s go with another predator as the other combatant Remember when I discussed how adult and juvenile Rex’s didn’t compete with each other because they hunted different prey Well, there are still predators that young Rex’s had to compete with for prey dromaeosaurus Now the Opera Raptor I mentioned earlier is a pretty small animal and likely ant hunt prey bigger in itself So that’s out of the question But there is another Raptor we can use Dakota Raptor this was discovered in 2005 and wasn’t named until 2015 so I’ll give this show some slack for not including it Dakota Raptor Stinney or steins Dakota thief after both South Dakota where it was found in Paleontologist Walter Stein was a giant dromaeosaurus Ah that reached five and a half meters or 18 feet long and is considered the second largest dromaeosaurus In a raptor Dakota Raptor was lightly built like other smaller dromaeosaurus unlikely only hunting animals around the same size or smaller that being it likely preyed on animals like Pachycephalosaurus ornithol – and other mid-size Herbivores if you haven’t noticed these are the same dinosaurs juvenile rocks is likely hunted Being these two animals likely competed for prey So a replacement episode would feature an adolescent t-rex in a Dakota Raptor going head-to-head Likely over a kill it doesn’t really matter who wins since it could go either way But once again the outcome shouldn’t be death. So what do we call this new episode? Well, how about Raptor vs. T-rex Yeah, I know that name is already used for a lighter episode but consider this a replacement for that too Overall this episode only drives the bar lower for this series, but don’t worry it gets Slightly better as we move forward That’s it for part two The analysis will continue with part three which will cover the third episode gang killers However, I will be taking a slight break from this series to post some other videos as of right now my next video is planned to be my first Natural History video which will cover the roots of the Tyrannosaur family tree back to the proceratosaurids and basal tyrannosauroids That’s all for today.

  1. 9:10 I hear they actually point out that the young Tyrannosaurus would look more like Nanotyrannusbin the show, and yet they don't modify the model of that for reasons

  2. 11:58 what about W-rex, or whatever specimen has proof of being female due to something on the bone birds get while pregnant.

  3. 14:05 sorry I'm to lazy ti edit, but what about the African Savannah, where predators, most notably the lion, kill competition, with lions at least rarely eating said kills. Unless you used humans and dolphins as an example and not the true "only intelligent animals kill for sport".

  4. I used to be big on the Nano= juvenile T.rex argument. While I'm still not sure about it being it's own genus, I find just as many if not more logical fallacies present in saying Nanotyrannus is just a juvenile t.rex than there is saying it was it's own genus. We now have juvenile T.rex specimens and they look quite different in several key areas. Tooth counts, jaw width, neck proportions, and arm size all agree with adult Tyrannosaurus rex but are markedly different than supposed Nanotyrannus specimens with those parts preserved. To give you an idea, a 5-6 meter long supposed Nanotyrannus called "Bloody Mary" has larger arms and bigger claws than Wyrex and Sue. The previous T.rex ontogeny by Carr was well thought out, but used the Cleveland skull as it's juvenile T.rex as no other possible juveniles were known at the time. Now that more and more are being found, something has to change.

    In essence the biggest problem I have with saying Nanotyrannus is just a juvenile Tyrannosaurus is it actually runs contrary to every single other Tyrannosauridae genera known. For example infant, juvenile, subadult, and adult Tarbosaurus bataar are known from multiple fossils. Throughout their maturation, this species often considered a close relative to Tyrannosaurus rex exhibits none of the maturation changes attributed to T.rex with things like arm size, tooth counts, and brain cavity shape largely being consistent.

    The video is well spoken and I commend the thoughts to it, but I find this particular area lacking.

  5. Actually T. rex isn't the biggest terrestrial carnivore. Mapusaurus, Charcarodontosaurus, Giganotosaurus and spinosaurus surpass it in size.

  6. I do agree now nannotyrannus is no more since that video post up thanks to your brother but for now maybe someday someone can find the real nannotyrannus

  7. 10:54 Looking more closely at that screenshot, and I think the Rex models here have the same case as the Ceratosaurus pair in "Hunter Becomes Hunted", as in the same physical models are used, but the colors are differently shaded. The darker, duller Rex to the left is most likely the mother (as we saw that exact same color on the one that killed the Nano), whilst the one on the right appears more saturated and brighter, most likely the father

    Just thought I'd make that observation, if ya don't mind ^^'

    EDIT: Wait, whoops, nevermind, that was already pointed out in-video, my bad ^^''

  8. Actually, it’s likely that Tyrannosaurus rex took care of their young first, like modern day birds bring their food to the best and by the age of 10 or something they probably teach them how to hunt.

  9. For a long time back intothousand 12 all the way through present I thought nannotyrannus what is a species of its own and I didn’t listen to a lot of people but until your video came then I said hey now nannotyrannus is a juvenile so 13 years I give up

  10. The evidence is really adding up that T-Rexes DID live in pairs, with one parent watching over the babies while the other would hunt. This would continue until the young were old enough to join the hunt, then it looks like they'd be basically trained by their parents how to hunt until a certain age, at which point they'd more than likely be driven from the family and sent off to start a new family of their own (the guess is they'd probably be around Jane's age when they had to leave).

  11. 11:55 Unless we'll find an adult Tyrannosaurus with fossilized eggs in its body. Assuming that is even possible, Idk, I'm not a paleontology expert

  12. I dunno what do you think about this link but for me nano is just juvenile T-rex now (also as a child I've liked this show and founded it accurate but now I find it to be ScheiBe) https://www.reddit.com/r/Paleontology/comments/a9qwwc/the_nanotyrannus_juvenile_tyrannosaurus_debate_a/

  13. I see a few people pointing out that Dakotaraptor is an invalid genus due to it being a chimera. Personally, I wouldn’t be so quick to dismiss it as in invalid genus. The only bone confirmed to be from a different animal, that being a turtle, is the wishbone. That large claw is most certainly for a large Dromaeosaur.

  14. Great video only complaint is that it sounds scripted like you’re kinda bored just reading. Try making your voice have more “personality” and I’m sure the videos will become better and better.

  15. Great Scientific facts about the episode of Jurassic Fight Club T. rex Hunter.
    I absolutely agree everything you said about the episode because I could already tell that the T. rex Mother abandoning her children which is not good parenting at all and letting her children get killed by predators.
    You’re right about the T. rex Mother.
