Paleontologists in Nevada have discovered a Triassic-era sea monster that is the size of a bus! It lived about 244 million years ago during the Triassic era. The creature is called “lizard-eating sovereign of the seas,” or Thalattoarchon saurophagis. T. saurophagis was an early ichthyosaur, a giant reptile that lived in the oceans.
The fossil was partially excavated in 1998, and National Geographic explorer and T. saurophagis study co-author Nadia Fröbisch and her colleagues excavated the rest of the fossil in 2010. The complete fossil has a huge skull and big, sharp teeth that may have been used to eat prey the same size as T. saurophagis.
