New Jersey's State Dinosaur
The duckbilled dinosaur, Hadrosaurus foulkii roamed the forests and swamps along the bays of New Jersey's ancient seacoast.
Today its bones are found in ancient marine deposits with fossil seashells.
It was about twenty-five feet long, probably weighed 7 to 8 tons and stood about 10 feet tall. Hadrosaurus probably stood on its hind feet when running, but used it front feet to support its head while grazing. Its abundant blunt teeth confirm that Hadrosaurus was a vegetarian, a peaceful plant eater that could chew tough-stemmed twigs and leaves. Hadrosaurus lived about 80 million years ago late in the Cretaceous Period.
Hadrosaurus is a famous dinosaur because it was the most complete dinosaur skeleton unearthed anywhere in the world when it was discovered and scientifically documented in 1858.
A video tour of the Academy exhibit
In 2008, 140 years after it became the world's first museum to display a mounted dinosaur skeleton, Philadelphia's Academy of Natural Sciences mounted a new exhibit. called "Hadrosaurus foulkii, The Dinosaur That Changed The World," It features a completely new skeleton mount of the famed fossil discovered in 1858 in a Haddonfield marl pit in Camden County, New Jersey.
Hadrosaurus foulkii became the official State dinosaur of New Jersey in 1991.
