Comment on Comparative anatomy
Not_mikey@slrpnk.net 2 months agoKangaroos hop because they can store a lot of energy in there Achilles tendon and use that to propel them forward without using much energy. It’s good for covering long distances over flat terrain while using as little energy as possible , which is good for the Australian outback as they hop between small patches of vegitation separated by miles of desert. It’s not that good for ambushing or quickly chasing prey in a rainforest like the t rex is probably doing.

Was gonna say, the tendon strength simply doesn’t scale like that, rexes are way too massive.

The probably pounced on their prey though when they were sure they would catch them.

We saw that in the Attenborough documentary, Jurassic Park.
