Exempel på hur man kan använda DIAPSIDS i en mening

• Sauria is the clade of diapsids containing the most recent common ancestor of Archosauria (which includes crocodilians and birds) and Lepidosauria (which includes squamates and the tuatara), and all its descendants.
• This view of placing turtles outside of diapsids is now outdated and the majority of modern paleontologists believe that the Testudines (turtles and allies) are descended from diapsid reptiles that lost their temporal fenestrae.
• Lepidosauromorpha (in PhyloCode known as Pan-Lepidosauria) is a group of reptiles comprising all diapsids closer to lizards than to archosaurs (which include crocodiles and birds).
• Youngina shows a mosaic of features found in more primitive diapsids and more derived taxa such as archosauromorphs and lepidosauromorphs suggesting a non-orthogenetic evolution of these characters.
• It is now commonly believed that euryapsids (particularly sauropterygians) are in fact diapsids (which have two fenestrae behind the orbit) that lost the lower temporal fenestra.
• In the Lufeng Formation, Sinosaurus shared its paleoenvironment with therapsids like Morganucodon, Oligokyphus, and Bienotherium; archosaurs like Pachysuchus; diapsids like Strigosuchus; crocodylomorphs like Platyognathus and Microchampsa; the early mammal Hadrocodium; and other early reptiles.
• These were accompanied by Anapsids or Parareptiles, which included both lizard-like and large herbivorous forms, and primitive diapsids.
• They instead found drepanosauromorphs to be archosauromorphs, possibly related to Prolacertiformes, and unrelated to weigeltisaurids or other early diapsids.
• The order has almost been treated as a dustbin for diapsids that are not obviously lepidosaurian or archosaurian.
• This placement within the diapsids suggests that the turtle lineage lost diapsid skull characteristics as it now possesses an anapsid skull.
• Unlike Petrolacosaurus, which possessed the two pairs of skull openings characteristic of diapsids, in Araeoscelis the lower pair of temporal fenestrae were closed with bone, resulting in a euryapsid condition.
• A group of archosauriform diapsids, Crurotarsi (including living crocodilians and their extinct relatives) is named after specialized crurotarsal joint in the skeletons of the members of this group, located between their fibula and calcaneum, with a hemicylindrical condyle on the calcaneum articulating against fibula.
• They are widely accepted as diapsids, but experts have variously placed them on the reptile family tree among Lepidosauromorpha (squamates, rhynchocephalians and their relatives), Archosauromorpha (archosaurs and their relatives), ichthyosaurs, and/or other marine reptiles.
• Turtles, though not diapsids in a purely anatomical sense, qualify as members of the clade Diapsida due to their likely diapsid ancestry.
• As with most early diapsids, small wedge-like bones known as intercentra fill in the gaps between vertebrae.
• Weigeltisaurids have generally been interpreted as neodiapsids that lie outside of Sauria (the group containing all living diapsids).
• Heleosuchus shares the hooked fifth metatarsal found in some other diapsids, such as primitive turtles (Odontochelys), lepidosauromorphs, and archosauromorphs, but it also resembles "younginiform"-grade diapsids in its gross morphology.
• Kayentachelys lived alongside hybodontoid chondrichthyans; the early anuran Prosalirus; the gymnophionan Eocaecilia; sphenodontid diapsids; several species of crocodylomorph, including Kayentasuchus, Eopneumatosuchus, Protosuchus, and the goniopholidid Calsoyasuchus; the pterosaur Rhamphinion; the sauropodomorph dinosaur Sarahsaurus; the theropod dinosaurs Dilophosaurus and "Syntarsus" kayentakatae; the ornithischian dinosaur Scutellosaurus; the tritylodontid synapsids Oligokyphus, Dinnebitodon, and Kayentatherium; the mammaliaform synapsid Dinnetherium; and several other yet-unnamed taxa.
• Although it lacks an infratemporal fenestra, Teraterpeton still belongs to Diapsida because it is a descendant of true diapsids.
• While Senter (2004) reassigned the bizarre, arboreal drepanosaurids and Longisquama to a group of more primitive diapsids called Avicephala, subsequent studies failed to find the same result, instead supporting the hypothesis that they were protorosaurs.
