 As I posted before, we went to an active dinosaur dig or quarry last Saturday.  This post is about other animals that they found there.  Some were also found at Dinosaur National Monument. 

Brasilichnium and a New Pterosaur


At and/or near Dinosaur National Monument Dr. Britt of Brigham Young Univeristy, Dr. Engelmann of the U of Nebraska, and Dr. Chure of Dinosaur National Monument have found many tracks and some fossils of a small mammal or maybe proto-mammal.  It is called Brasilichnium.  It was a smaller animal, about a foot or .3 meters long.  It was built a bit like a mole and clearly lived in burrows. 
They also found a new or previously unknown Pterosaur at the site.  This flying reptile must have  hunted the mammals.  It lived in a sand dune desert.  It even had 4 one inch fangs.  It also had a lower jaw that was longer than the upper jaw. It's wingspan was about 4.5 feet or 1.3 meters long.  It actually had a total of 110 teeth!

The site where these animals were found included one of the first dinosaurs called Coelophysis and mini proto-crocodiles called Sphenodonts.  (see previous posts).  This site was an oasis with a lake in the middle of the sand dune desert that now is turned to sandstone, (sometimes called frozen dunes).
