The Appalachian mountains, span the Eastern margin of the United States of America. They are predominantly composed of Paleozoic rocks, but Mesozoic marine sediments (formed adjacent to the Appalachian continent at the time) can be found along the Eastern coast. It is within these deposits that the remains of a unique dinosaur fauna can be found.

Joining us to paint a picture of the vertebrate faunas of Appalachia during the Mesozoic is Chase Brownstein, research associate at the Stamford Museum and Nature Centre.
