 Palaeos Vertebrates 200.100 Anapsida: Basal Anapsids
Image and Note: Eudibamus cursoris from the Upper Permian of Germany, is the earliest known biped.
Characters: Palate without teeth; transverse flange of pterygoid in same plane as palate; dentary and surangular form tall coronoid process; proximal portion of dentary covered by anterior process of prearticular; bulbous, occluding teeth; temporal fenestra long and low, between jugal and squamosal dorsally and quadratojugal ventrally; herbivorous.
Characters: Simple, conical teeth; retention of tabular, large supratemporal and postparietals; some forms with lateral temporal fenestra, but independently derived; lower temporal bar incomplete; stapes relatively small(?), light; impedance-matching ear likely; squamosal and quadratojugal embayed to support tympanum like diapsids (?) but unlike Testudines, which use quadrate; lizard-like?

 Introduction to Anapsida
By the Upper Permian, anapsids are also known from Europe, Asia, and Africa.
The geographic origin of Anapsida has not yet been determined because the fossil record of Paleozoic tetrapods is too poor and localized, but the oldest known anapsid comes from the Lower Permian of North America.
The clade Anapsida includes turtles and all their extinct relatives, which include millerettids, procolophonoids, pareiasaurs, as well as more poorly known taxa such as Acleistorhinus, lanthanosuchids, and nyctiphruretians.

 Turtle - Encyclopedia.WorldSearch
Turtles are the only surviving branch of the even more ancient clade Anapsida, which includes groups such as the procolophonoids, millerettids and pareiasaurs.
Re-analysis of prior phylogenies that affirmed an anapsid ancestry suggests that their inclusion of turtles within Anapsida was due to both the starting assumption that they were anapsid (most prior phylogenies concerned what sort of anapsid they were) and also due to insufficiently broad sampling of fossil and extant taxa for construction of the cladogram.
All other extant amniotes have temporal openings (although in mammals the hole has become the zygoid arch).

 ANAPSIDA
The MILLERETTIDAE were small insectivorous reptiles that seem to be a specialized set of the anapsida that had developed an extra pair of skull openings.
They have been found only in South Africa.
The best known examples are Parieasaurus and Scutosaurus.

 Anapsid : Anapsida
It uses material from the wikipedia article Anapsid : Anapsida.
The anapsids have traditionally been treated as a subclass of the class Reptilia, but as this group is paraphyletic they are sometimes placed in a separate class Anapsida.
Various other groups, however, are known from Permian and Triassic fossils.

 Anapsida: Fossil Record
The oldest known member of Anapsida is Acleistorhinus, a small reptile from the Lower Permian of Oklahoma.
However, the presence of romeriids (the sister-group, or closest relatives, of anapsids) in the Middle Pennsylvanian indicates that Anapsida originated no later than the Middle Pennsylvanian.
Therefore, a long hiatus exists in the fossil record of anapsids.
