Protostega gigas

Fossil sea turtle from the Taylor Group of Texas.

First discovered in Kansas in the Niobrara Chalk and named by E.D. Cope, Protostega had a somewhat reduced shell for streamlining and weight reduction, probably helping it swim with more speed and agility. This replica is cast from a specimen which was found near Dallas, Texas and is the largest Protostega in the world. With flippers spanning fifteen-and-a-half feet, our Triebold Paleontology's Protostega makes an impressive exhibit.

  • Locality: Texas
  • Formation: Taylor Group
