MemberCompsognathusAug-09-2013 12:52 PMI've been doing some research to see if Tyrannosaurus rex can run quickly. First of all, the size of T-rex does not affect how fast it could run. I watched a few videos of charging elephants and they were hitting speeds well over 15-20 miles per hour. Obviously just because something is really large, does not mean it can't run fast. While I was visiting Baltimore, I made sure to see what the legs of Tyrannosaurus were like. While not the longest legs compared to body size, they were long nonetheless and very powerful. I don't think T-rex was the speedy killer like in Jurassic Park, but it was not a lumbering behemoth either.
All in all, here's how I break down the speed of T-rex. It's size would affect it's speed to a degree, but not by much...
7-8 ton T-rex- 20-25 miles per hour
9-10 ton T-rex- 15-20 miles per hour
11+ ton T-rex- 10-15 miles per hour
With a top speed of 25 miles per hour, Tyrannosaurus was certainly not the fastest carnivore out there, but for something that weighs over 7 tons, it was quite fast.

MemberCompsognathusAug-09-2013 3:16 PMTrue, but who says it's prey was not fast. Triceratops could probably charge like a rhino. Maybe as fast as 20 miles per hour or so. Hadrosaurs could probably move pretty fast on two legs if they had to as well.

MemberCompsognathusAug-09-2013 4:22 PMRex Fan, even a rex of 7 tons would need a lot of oxygen to fuel its large and bulkie body. The thing is, rex doesn't have a respitory system to do that. A T. rex would néed to breath in and out, instead of a raptor, who has a design to only need to breath in and the air flow leaves its body through its hollow bones and openings in be skin. This is from jurassic fight club by the way.

MemberCompsognathusAug-09-2013 6:42 PMI saw that too. For one thing, the tyrannosaurs were pretty closely related to the raptors. The more primitive carcharodontosaurs, as mentioned in Planet Dinosaur, had very efficient breathing strategies. T-rex, a more advanced predator than the carcharodontosaurs and close relative of raptors, would have had a pretty good breathing system too.

MemberCompsognathusAug-09-2013 6:44 PMI'm not sure. It had a lot to do with the bones. T. rex had thick, solid bones, not good for letting air through. I think some of the rexes could have a pretty good air flow system, but T. rex himself, I don't think so.

MemberCompsognathusAug-09-2013 7:03 PMI don't know, T-rex was the most advanced tyrannosaur. If it's earlier cousins had it, it's close relatives the raptors, and the more primitive carcharodontosaurs, it seems strange that T-rex did not. The carcharodontosaurs were also giant predators like T-rex. The same size class.

MemberCompsognathusAug-09-2013 7:21 PMOh, and I found out that Tyrannosaurus had "honeycomb" structures in it's bones. This would have forced air out so it always had a fresh supply, similar to the raptors. Also, if dinosaurs were warm-blooded, which I think they are, T-rex would have been pretty active and likely had a 4 chambered heart like crocodiles and birds, their closest living relatives.

MemberCompsognathusAug-09-2013 8:35 PMAlmost all dinosaurs had honeycomb bones. I think T. rex could pick up speed very fast but couldn't maintain it long. Hadrosaurs, which were undoubtably faster, probably couldn't pick up speed fast but could run faster (~30-35 mph). I think Tyrannosaurus would have been a great ambush hunter.

MemberCompsognathusAug-09-2013 10:00 PMI don't think rex could make it above 20. It was extremely heavy for its size, and even though it has large, strong legs, it really isn't designed to run.

MemberCompsognathusAug-13-2013 12:13 AM25 miles per hour sounds about right for a T-Rex to have run, even though it was probably an ambush predator. The juveniles probably did run faster than that though.

MemberCompsognathusAug-13-2013 8:49 AMJuveniles between 13-23 ft and .5-2 tons could probably hit speeds of over 30-35 miles per hour and hold that speed for some distance. Then, as they grew, their top speed decreased to 25 miles per hour over a somewhat short distance.

MemberCompsognathusAug-17-2013 8:49 AMI believe T-Rex would probably note chase its prey but probably ambush using a short burst of speed to surprise prey,i don't think it was built for long distance.
