Fly River Turtle

Interesting shell shape, is that common in this species? I seem to remember the ones I have seen having much flatter shells.

@Mayki I am not too familiar with the species but this type of shell formation I’ve seen on at least a couple other Fly River turtles in person. There’s a Fly River turtle I’ve seen through the Bronx Zoo social media pages that has an almost similar shell to this one and its about 60 years old, perhaps it correlates to age
