Utuntu dushimishije
Eonatator's tail made up about 40% of its head and body length, helping it swim fast.1
The first Eonatator fossil was found in the Niobrara Chalk of Kansas in 1918 by Charles Hazelius Sternberg and his son Levi.1
Eonatator was originally thought to be a species of Clidastes or Halisaurus, but scientists gave it its own genus in 2005.1
A second species, Eonatator coellensis, was discovered in Colombia and named after the town of Coello.1
Eonatator had a smooth, triangular bone on top of its skull with a round hole called the parietal foramen.1
Like many mosasaurs, Eonatator gave birth to live young instead of laying eggs.2
