The popular scientific theory is that the Tyrannosaurus, while large and fearsome, was a scavenger and not a predator. This means that it probably did very little running, and when it did, it did not entirely leave the ground. It most likely achieved a "fast" walking pace.

The Speed of an animal is often determined by the scale difference between the femur and the lower leg bones. Animals with shorter femurs tend to be faster while those with longer more "human-like" leg bones are on the slow side. The T-Rex had a very large femur, nearly equal in length to it's lower leg bone. It's top speed was most likely around 17.9 mph- that's fast enough to outrun our fastest sprinters.

  • or t.rex was chasing the hard of hadrosaurs, its strong evidence theres no single fossil evidence supporting the scavenger theory meant that it was mostly predator, good eye sight,good sense of smell was used for predators too not just scavengers, and strong bite force does not mean scavenger to be in common with hyenas again hyena's were not pure scavengers

  • @cf572

    I think you are completely right. I think the t-rex was completely capable of both. In my game the t-rex wil. Be a hunter and will attack the player.

  • nice. which programs have u used (except blender)? is there a normal map?

  • @brezakcz

    This was made in blender with the help of photoshop! Yes there is a normal map! Thanks :)

see all

  • @cf572 I agree. I think it was too large to be purely a scavenger. If you look at today's scavengers, that is those that survive on already dead animals they are small. Think vultures and buzzards. Hyenas are large and although they do scavenge also kill and eat their prey at times. Even lions will scavenge, stealing prey from hyenas that may have brought that particular prey down. No, T-Rex was nor only a scavenger but also a fearsome predator. The apex

    predator of it's day!

  • @cf572 thanks basically what i siad....

  • and finally guys, a fossilized track was found of t.rex foot strides tracks with hadrosaur foot tracks meaning t.rex was hunting that track was found even before that stupid scavenger theory i dont know why most people agreed with this stupid theory back then,

  • @sdzoo2000 secondly hyenas were not entirely scavenger, jack honer said he was 100% scavenger, well TO BE A 100% SCAVENGER you need to fly to search far distances because dead food is always available you can find them fast if you fly, t.rex cant fly and most people agree t.rex mostly hunted, and2ndly bite marks found on the tail of an edmontosaurus just one tooth mark fitting a t.rex tooth but t.rex did not eat it because the skeleton was not shreded meaning edmonto escaped meant trex hunting

  • @sdzoo2000 actually theres evidence that it mostly hunted, jack honer said it was a scavenger because of its tiny arms i heard rumors that he said no predator kills using only its mouth, what about sharks? crocodiles? they dont scavenge they hunt and they dont use claws, snakes,eels,birds,ants, it begs an explenation and the fact it ran slow? it is now know that t.rex ran fast it hand muscles in the thighs extending to the tail for faster speed and a slender leg so mostly huner

  • HONESTLY EVERYBODY- the T-rex was both. the trex scavenged as much as it could....however, there is eevidence that it hunted as well. In the 1990's or early 2000's they discovered broken off tre teeth in an injured edmontosaurus. Also, why would the trex have naturally forward pointing eyes (common in most predators) instead of to the side if it were a pure savenger? Some scientists think the trex could only run 11 mph (i think its more so 20-22 mph) it would be fast to catch slow herbivores

  • @TIMELESSTHEGAME So when WILL it come out?
