Crassigyrinus (meaning "thick tadpole") is an extinctgenus of carnivorousstem grouptetrapod from the Early Carboniferous of Scotland and a possible specimen from Greer, West Virginia. The type specimen was originally described as Macromerium scoticum and lacked a complete skull. With subsequent discoveries, Crassigyrinus is now known from three skulls, one of which is in articulation with a fairly complete skeleton, and a couple of incomplete lower jaws. Crassigyrinus grew up to 1.5 meters in length, coupled with punitive limbs and unusually large jaws. Crassigyrinus is taxonomically enigmatic, having confused paleontologists for decades with its apparent fish-like and tetrapod features. Some paleontologists have even considered it as the most basal tetrapod, while others hesitate to even place it within the Tetrapoda superclass. Crassigyrinus had unusually large jaws, enabling it to eat other animals it could catch and swallow. It had two rows of sharp teeth in its jaws, the second row having a pair of fangs. Crassigyrinus had large eyes, suggesting that it was either nocturnal, or lived in very murky water. (Read more...)
... that Irritator is only known from a skull that was badly obscured by plaster which was added by the commercial fossil-collecting fossil-poachers who illegally sold it in hopes of making the fossil look more complete and valuable?
... that rhynchosaurs had unique teeth that were modified into broad tooth plates?
... that a trackway produced by an unknown crocodyliform that measured approximately 12 meters in length was uncovered in the Galve region of Spain?
"When you were here, you stated that you should like to employ one or more young men to collect fossils in western Kansas. As perhaps you may have learned, I have been summarily discharged (with two other professors) from this college. This has been done by an incompetent, conceited clergyman, who is acting as president."
This fossil skeleton of Dorudon, around 50 million years old, has been partially excavated and reassembled where found in Wadi Al-Hitan. Dozens of whale skeletons remain undisturbed on the floor of the valley, usually indicated by small mounds created as wind erosion uncovered them. Dorudon was a genus of ancient cetacean that lived alongside Basilosaurus 41 to 33 million years ago, in the Eocene. They were about five meters (16 ft) long and were most likely carnivorous, feeding on small fish and mollusks. Dorudontines lived in warm seas around the world. Fossils have been found in North America, Egypt as well as Pakistan the eastern part of which bordered the ancient Tethys Sea.
