Exempel på hur man kan använda ARCHOSAUR i en mening

• dicynodont Jachaleria candelariensis, an unclassified phytosaur, and isolated teeth of archosaur origin can also be unearthed in the formation.
• Archosauriforms are a branch of archosauromorphs which originated in the Late Permian (roughly 252 million years ago) and persist to the present day as the two surviving archosaur groups: crocodilians and birds.
• Rauisuchians, as a traditional taxonomic group, were considered distinct from other Triassic archosaur groups such as early dinosaurs, phytosaurs (crocodile-like carnivores), aetosaurs (armored herbivores), and crocodylomorphs (lightly-built crocodilian ancestors).
• It was hypothesized to be a basal theropod, a basal sauropodomorph, a basal saurischian, or not a dinosaur at all but another type of archosaur.
• Paleosaurus – subsequently found to be a non-dinosaurian archosaur; junior synonym (unneeded replacement name) of Palaeosaurus.
• Sharov determined that it was a "pseudosuchian" (a "primitive" archosaur, but as an archosaur a relatively derived reptile) on the basis of two features: a mandibular fenestra and an antorbital fenestra.
• Spondylosoma (meaning "vertebra body") is a genus of avemetatarsalian archosaur belonging to the clade Aphanosauria from the late Ladinian-age Middle Triassic Lower Santa Maria Formation in Paleorrota Geopark, Brazil.
• Schoch in 2013 when they realized that it represented a primitive loricatan archosaur rather than a dinosaur or a crocodylomorph, as a result of further preparation of the specimen.
• Clepsysaurus was traditionally classed as a sauropodomorph, Clepsysaurus was eventually seen as a synonym of either the dubious archosaur Palaeosaurus or the sauropodomorph Anchisaurus, but Clepsysaurus was eventually resurrected as a valid, but dubious, genus.
• huenei, originally considered a pseudosuchian archosaur and then a rhynchocephalian lepidosaur, was largely ignored in the scientific literature, as its small size and fragility did not permit further mechanical preparation and examination.
• Galtonia, upon being identified as its own genus separate from Thecodontosaurus, was initially classified as an ornithischian, but was seen to be Revueltosaurus, which is actually a non-dinosaurian archosaur.
• Palaeosaurus (or Paleosaurus) is a genus of indeterminate archosaur known from two teeth found in the Bromsgrove Sandstone Formation and also either the Magnesian Conglomerate or the Avon Fissure Fill of Clifton, Bristol, England (originally Avon).
• Riojasuchus is an extinct genus of ornithosuchid archosaur from the Late Triassic (Norian) of Argentina.
• Nyasasaurus (meaning "Lake Nyasa lizard") is an extinct genus of avemetatarsalian archosaur from the putatively Middle Triassic Manda Formation of Tanzania that may be the earliest known dinosaur.
• Several dinosaur and other prehistoric archosaur species are facultative bipeds, most notably ornithopods and marginocephalians, with some recorded examples within sauropodomorpha.
• Teleocrater (meaning "completed basin", in reference to its closed acetabulum) is a genus of avemetatarsalian archosaur from the Middle Triassic Manda Formation of Tanzania.
• Supposed Erythrosuchus fossils reported from the Omingonde Formation of Namibia were later described as Etjosuchus, a "rauisuchian" (loricatan) archosaur.
• Ticinosuchus is an extinct genus of suchian archosaur from the Middle Triassic (Anisian - Ladinian) of Switzerland and Italy.
• In the case of mosasaurs though, they differ from the thecodont dentition pattern of archosaur and mammals because mosasaurs show true ankylosis and not a fibrous tooth attachment via periodontal ligament that's usually found in mammals and archosaurs.
• They constitute an evolutionary grade of animals, a "wastebasket taxon" for any archosaur other than a crocodilian, a pterosaur, or a dinosaur (any basal archosaur).
