Reptiles from the Late Triassic

By Amanda Simms

Turtles Basking on the Anacostia

I’m not talking about dinosaurs; I’m talking about turtles. It may surprise you to know the turtles existed when the last of dinosaurs were evolving in the late Triassic period, about 230 million years ago. Turtles can be found all over the world and there are approximately 300 species living today.

In the Anacostia watershed, we have 19 species of turtles. The most common in suburban areas (your backyard) is the box turtle. In coastal plain areas musk and mud turtles are most common. In different types of water, from freshwater to brackish (a mix of salt and fresh water) we see more snapping turtles. And in larger bodies of water like the Chesapeake Bay and the Atlantic Ocean, sea turtles lurk.
