Hope that's helpful. Maybe you could post a pic of yours and we could tell you what you have?
Welcome! I'm new too. I'm temporarily keeping a wild eastern box turtle...very friendly, eats well, easy to care for in outdoor set up. they make great pets, but I'm letting mine go after a turtle race in my town.
Terrapene Carolina Carolina is the Eastern subspecies and its the state reptile of North Carolina.
