The Dinosaurs and Prehistoric Animals of New York


No dinosaurs have ever been discovered in New York--but that doesn't mean the Empire State was completely bereft of prehistoric life, as listed below. (See an interactive map of dinosaurs and prehistoric animals in the United States.)

1. American Mastodon

New York State Museum
In 1866, during the construction of a mill in upstate New York, workers discovered the near-complete remains of a five-ton American Mastodon. The "Cohoes Mastodon," as it has become known, testifies to the fact that these prehistoric elephants once roamed the expanse of New York in thunderous herds (probably alongside their close Pleistocene contemporary, the Woolly Mammoth).

2. Eurypterus

A little over 400 million years ago, during the Silurian period, much of North America was submerged under water. The official state fossil of New York, Eurypterus was a type of marine invertebrate known as a sea scorpion, and was one of the most feared undersea predators before the evolution of sharks and giant marine reptiles.
