Wow, the animation was pretty bad. But if it was on a low budged and limited time, i guess it is allright.

allosaurus model looks super flipping derpy and allosaurus was part of a completely separate group of theropods

Urry Clark Film May 22, 2016 - 4:46 PM

the allosaurs had a weak bite force no stronger than the komodo dragon and the all therapod dinosaurs hands were in a "clapping" motion

Allosaurus was not related to tree and also allosaurus jaws was surprisingly weak, even lions bite force is stronger

Allosaurus is like a cross between a Komodo Dragon a Lion an Eagle and a Monitor

ThunderTurtle 365 June 5, 2018 - 5:11 AM

Allosaurus doesn’t have powerful jaws and it’s not a cousin of T. rex where did u get that shit from

DinoBooks 101 June 5, 2018 - 11:19 AM

Inaccurate and looks totally fake.

CallOfTheSyren June 11, 2018 - 7:14 PM

Poor allosaurus has broken wrists :'(

Super Mario Logan Fan June 21, 2018 - 11:12 PM

Allosaurus is a cousin of T-Rex because both a theropods

PhantomsHyper July 2, 2018 - 1:41 PM

its jaws r not powerful

AaishaM3 July 4, 2018 - 6:11 PM

1. Allosaurus had anything but a powerful bite. Their teeth were sharp and designed to tear flesh, but their bites were VERY weak. However, there skulls were capable of enduring a LOT more force than their estimated bite force, leading paleontologists to believe that they perhaps used their upper jaws like hatchets.

2. Theropods, like allosaurus, could NOT pronate their limbs. Sure, there is a piece of supportive evidence on smithsonians website that suggests a certain large theropod had held it's forelimbs vertical, or palms-downward, to rake the ground. However, it is suggested they could do this by sticking their elbows outward and turning their entire limb. Other's believe that most couldn't pronate their limbs, but perhaps some had increased mobility allowing a partially pronated position. However, keeping their hands completely palm-downward has been, until now, been considered impossible. Unless further fossil evidence can completely disprove this theory, it will be considered a fact.

3. Matter of personal opinion, I know, but this video has such a game-like and artificial look to it.

Yes, allosaurus was DISTANTLY related to t.rex (being a theropod) however it was also distantly related to other theropods such as velociraptor and birds.

RRB_95 July 22, 2018 - 1:31 AM

What if they fight to a draw? Allosaurus gets a fatal bite in but stegosaurus manages to pierce his heart? Lol

NXB player August 14, 2018 - 1:58 AM

Allosaurus is bigger then carntosaurus

NXB player August 14, 2018 - 1:59 AM

How is Allosaurus vs. Stegosaurus "Mammals vs. Dinos"?

Casey Rowe July 1, 2019 - 9:33 AM

Truly enjoyed the video. :)

Metriacanthosaurus vs kentrosaurus

Wtf. Stegosaurus doesn’t have spike rounded plates.

Paleo PH July 8, 2020 - 3:20 PM

At least the Stegosaurus tail spikes are accurate. They faced sideways not upward. They swung their tail 'side to side' not 'up and down' therefore the thagomizers faced sideways.

Jonathan Huertas November 29, 2020 - 5:56 AM

Stegosaurus was as solitary and rare as a rhinoceros.

Fredrick Reed December 7, 2020 - 6:24 PM

Who in hell said T. rex was a cousin of an allosaurus, dude has a weaker bite then a lion.
