Re: AQUATIC THEROPODS!!
Concerning swimming theropods -
Most animals are good swimmers. Throw
a cat in the water and it will swim just fine thank you. Elephants are good
swimmers ( as shown on some recent TV ads) that move between islands. The big
ground birds, emus etc, have been observed swimming across rivers etc. With
their long bird-like legs with long toes, and a sculling tail, theropods were
probably better swimmers than birds, but not as good as crocs. This does not
mean they were specialized swimmers, just that they could when needed, and
were able to pursue prey into the water (like some living big carnivores do).
So sauropods and hadrosaurs probably did not find safety by dashing into
water. There are trackways that may show scratch marks by the claws of
swimming theropods, but this is not certain.
