Diapsida Classes Ichthyosauria Sauropterygia Lepidosauria Archosauria Diapsids (two arches) are a group of tetrapod animals that developed two holes (temporal fenestra) in each side their skulls, about 300 million years ago during the late Carboniferous period. ...

Eureptilia is one of the two major clades of the Sauropsida, the other being Anaspida or Parareptilia. The Eureptilia include not only all Diapsids, but also a number of primitive Permocarboniferous forms previously clasisfied under the Anaspida, in the old (no longer recognised) order "Cotylosauria". Greek clados = branch) or phylogenetic systematics is a branch of biology that determines the evolutionary relationships of living things based on derived similarities. ...

Primitive Eureptilians were all small to smnallish, superficially lizard-like forms, that no doubt scurried through the Paleozoic undergrowth in search of insects.


The Diapsids are the only eureptilian clade to continue beyond the Permian period The Permian is a geologic period that extends from about 280 to 248 million years before the present (mya). ...


The clade is defined by the skull having greatly reduced supraoccipital, tabular, and supratemporal bones that are no longer in contact with the postorbital. A Hippopotamuss skull A skull, or cranium, is a bony structure of vertebrates which serves as the general framework for a head. ...

Eine erste Aufspaltung fand sehr früh in uneigentliche Reptilien (Parareptilia) und eigentliche Reptilien (Eureptilia) statt.
Die Eureptilia spalteten sich in eine Vielzahl von Zweigen auf.
Der Zweig der Archosauria umfasst die Krokodile, die Flugsaurier und die Dinosaurier (und damit nach heutigem Verständnis auch die Vögel).

The Eureptilia would have been a footnote in the history of turtles and mammals but for the evolution of the diapsids.
