Euryapsida are a group of tetrapod animals that are distinguished by a single opening behind the orbit (temporal fenestra). They are different from Synapsida by the precise placement of the opening below. It is now commonly believed that euryapsids are in fact diapsids (having two fenestrae) that lost the upper temporal fenestra.
