Tracks Across Time

Sometimes we get more information from things other than the fossilized bones of ancient animals.  Tracks are one of these amazing resources.  We can learn from fossilized tracks just how muscles and skin on the feet looked.  We can also learn, as is the case at Johnson's farm in Utah that dinosaurs could swim, we see where they sat on their haunches and can see how their running stride differed from their walking gait.
These tracks are an amazing scientific resource and a tremendous collector piece.

Many people do not know that dinosaur tracks are names, but not for the dinosaur that possible made them.  They are described, just like any fossil, by their individual attributes.  These tracks are called Grallator and were possibly made by Coelophysis ot Dilophosaurus.
