did Tyranasaurus Rex hop like a kangaroo?

[brainhulk]

I just can't help but notice the similarities in body structure. Did jurassic park get it all wrong?

 

[ThatsABigOne]

No, you are wrong. Jurassic Park is a history lesson. :hmm:

I think it would be wonderfully hilarious if they did.

Ask raptor jesus.

It weighed 7 tons. It would need some pretty massive legs to spring all that weight forward. Plus it looked like most of the weight was already forward, to me jumping around on that frame would just make it topple over.

Given the size and body mass of a T-Rex, I'd say it's unlikely. The smaller species, however,...who knows?

 

[Pardus]

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.

Too many calories for its size.

Here is an article stating a T-Rex femur contained proteins similar to a chicken.
http://www.wired.com - Origin of Species: How a T. Rex Femur Sparked a Scientific Smackdown


Spine, Hip, Leg, Belly and Pubis Bone Structure
T-Rex is more similar to a chicken than a kangaroo.

Foot Structure
T-Rex is more similar to a chicken than a kangaroo. However, the chicken has a developed fourth claw in the back that appears vestigial in T-Rex.

Arm and Tail Structure
T-Rex is more similar to a kangaroo.

Head Structure
T-Rex has a head much heavier than both the kangaroo and the chicken.


Chickens tend to bob up and down on their legs, similar to a repeating squat movement. I can see T-Rex doing the same.

I have a hard time seeing a femur move back and forth around that potbelly to the extent necessary to walk or run.


Which rhythm seems more appropriate for the hip, spine, and tail?

• An up-down undulating rhythm similar to a hopping kangaroo, or
• the side to side swing necessary to move one leg in front of the other for walking like a chicken.

The forum where I found this thread and borrowed the picture from may be better suited to answering your question.

Too many calories for its size.

There was far more oxygen in the atmosphere with a higher pressure than we have today. The enhanced oxygen would provide more energy. T-Rex had the mouth and stomach for ingesting a large amount of food to support such movement.

This can't be a serious thread.

Shit man, that's deep.

What? no Jesus on a T-Rex pics? For shame ATOT, for shame.

 

[Arcadio]

I actually laughed out loud when I imagined a T-rex jumping all over the place like a kangaroo.

 

[DaveSimmons]

No, but it boxes with puddy tats now and then.

 

[angminas]

They'd get stuck all the time doing that.

 

[foghorn67]

The thought of this makes me want to giggle.
