The shells could reach a length of at least 50 centimetres (1.6 ft) for North American species, some species like A. kohaku had carapace length of 60 centimetres (2.0 ft).[1] The largest species, A. kirtlandius had carapace reaching 113 centimetres (3.71 ft).[2] These large freshwater turtles had an omnivorous diet. They lived from the Late Cretaceous to the Paleocene in North America, but in Asia, they were also present during the Oligocene.
