anapsida การใช้

• Furthermore, Anapsida is rarely considered a valid clade in recent phylogenetic analyses.
• Accordingly, they have historically been classed alongside the turtles under the Anapsida.
• The traditional group Anapsida was rejected as paraphyletic.
• He placed it within Anapsida in its own order " incertae sedis ".
• It was believed they are the only surviving branch of the ancient evolutionary grade Anapsida, which includes groups such as protorothyrids, and pareiasaurs.
• Indeed, Gauthier, Kluge and Rowe ( 1988 ) themselves included only turtles and Captorhinidae in their Anapsida, while excluding the majority of anapsids in the traditional sense of the word from it.
• "' Parareptilia "'( " at the side of reptiles " ) is a subclass or clade of reptiles which is variously defined as an extinct group of primitive anapsids, or a more cladistically correct alternative to Anapsida.
• This definition explicitly includes turtles in Anapsida; because the phylogenetic placement of turtles within Amniota is very uncertain, it is unclear what taxa, other than turtles themselves, would be included in such defined Anapsida, and whether its content would be similar to the Anapsida of tradition.

• The presence or absence of temporal fenestrae is an important consideration in the phylogeny of mesosaurs and other amniotes because the three major groups of amniotes-Synapsida, Diapsida, and Anapsida-have been named after the number of holes in their skull; Diapsida means " two arches " in reference to the two bars that close off the upper and lower fenestra, Synapsida means " fused arch " in reference to a single bar at the bottom of the skull closing a single fenestra, and Anapsida means " no arch " in reference to skulls that lack any bars or fenestrae.
