Systematics
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]
