"Baenids existed from the Jurassic to the Eocene, and many species are known from throughout Hell Creek, including the charismatically named taxa Gamerabaena (Gamera Turtle) and Stygiochelys (Hell Turtle)."

― Saurian: A Field Guide to Hell Creek

Stygiochelys was a baenid turtle known from the Hell Creek Formation. Like most baenid turtles, it was probably a small aquatic creature, feeding on small invertebrates.

In Saurian Edit

There is no art concepts or any plans for the inclusion of the Stygiochelys in the game. However, this turtle is mentioned in the official game's artbook.
