Families | |
Testudinoidea is a superfamily within the suborder Cryptodira of the order Testudines. It includes the pond turtles (Family: Emydidae), Asian turtles (Family: Geoemydidae), the monotypic big-headed turtle (Family: Platysternidae), and the tortoises (Family: Testudinidae).
A 2021 study found the clade to be divided into two extant groups: Testuguria, containing Geoemydidae and Testudinidae; and Emysternia, containing Emydidae and Platysternidae. The extinct Lindholmemydidae, formerly classified in Testudinoidea, may fall outside the crown group of Testudinoidea, although there is not yet enough evidence for this. [2]
