(Phys.org)—A pair of researchers in the U.K. has identified fossils found in the Transylvania area in Romania as those of a pterosaur they have named Hatzegopteryx—a giant, muscle-bound flying reptile that could eat prey as large as a small horse. In their paper published in the journal Peer, Mark Witton with Portsmouth University and Darren Naish, with the University of Southampton describe the fossils and what they believe the creature looked like when it was alive.
