Astrodon johnstoni Leidy, 1865 |
Astrodon was a large herbivorous dinosaur that lived in what is now the eastern United States during the Early Cretaceous period, from 95 to 130 million years ago. Adults are estimated to have been more than 30 feet high and 50 to 60 feet long.
[edit] Discovery and Species
Sauropod material was found in the Arundel Formation near Bladensburg, Maryland and named Astrodon in 1859 by Christopher Johnson. However Johnson did not attach a specific epithet, so Joseph Leidy is credited with naming Astrodon johnstoni in 1865.
In 1998, Astrodon johnstoni was named the state dinosaur of Maryland.
