Exempel på hur man kan använda AUTAPOMORPHIES i en mening

• Its distinctiveness is the result of the strong selective pressure on its island home, which enforced the evolution of conspicuous adaptational autapomorphies.
• Benton also indicated some unique derived traits, or autapomorphies, for the species: a long basipterygoid process on the braincase; a dentary that is short in relation to the total length of the lower jaw; an ilium that has a back end that is subquadrate instead of rounded.
• Significant post cranial autapomorphies of Suminia are the reduced number of presacral and dorsal vertebrae (exclusively amphicoelous) with lack of fusion in the sacral region between vertebrae (suggests high flexibility), wide pre- and postzygapophyses, longer proportions of cervical pleurocentra, distinct proportionally longer limbs, a manus that forms ~ 40% of the length of the forelimb with particularly long, curved terminal phalanges, a pes that makes up ~38% of the hindlimb, and enlarged carpal 1 and tarsal 1 (suggests divergent first digit).
• However, Darren Naish in 2007 concluded that the specimen showed two unique derived traits or autapomorphies, in that the second metatarsal is both mediolaterally compressed and features a prominent dorsolateral ridge.
• A later study concluded the two species to be indistinguishable except for size, but other authors consider any identity to be unprovable as there are no comparable remains and conclude both species to lack autapomorphies and therefore to be nomina dubia.
• A reassessment of the holotype UCMP 34498 of Camposaurus arizoniensis by Ezcurra and Brusatte revealed two autapomorphies, thereby firmly establishing this material as a valid genus and species.
• Irmis, Nesbitt and Sues (2013) noted that some of the material referred to this taxon is actually dinosaurian; however, according to the authors, the holotype specimen PVL 2561, found in the Cancha de Bochas Member of the Ischigualasto Formation in the Ischigualasto-Villa Unión Basin in northwestern Argentina, "comprises a single individual that preserves unambiguous crocodylomorph synapomorphies", indicating it is indeed a crocodylomorph, and one of the referred specimens, PVL 3889, does share one or more autapomorphies with the holotype, indicating it represents the same taxon.
• This position is supported by the presence of two autapomorphies common on both Lapparentosaurus and Cetiosaurus: a pyramid-shaped neural spine from the anterior dorsal vertebrae with tapering in shape or not flaring distally and loss of the spinodiapophyseal lamina on the dorsal vertebrae.
• The autapomorphies that distinguish Epachthosaurus from other genera are: middle and caudal dorsal vertebrae with unique articular processes extending ventrolaterally from the hyposphene; a strongly developed intraprezygapophyseal lamina, and processes projecting laterally from the dorsal portion of the spinodiapophyseal lamina; hyposphene-hypantrum articulations in caudals 1–14; and a pedal phalangeal formula of 2-2-3-2-0.
• Laurin & Reisz, 1995 and Laurin & Gauthier 1996 defined the Procolophonia cladistically as "The most recent common ancestor of pareiasaurs, procolophonids, and testudines (Chelonia), and all its descendants", and listed a number of autapomorphies.
• This result suggests that the many autapomorphies (unique traits) of the false catshark evolved relatively recently, and supports the grouping of Pseudotriakis and Gollum together in the family Pseudotriakidae.
• Alongside Cetiosaurus from the Middle Jurassic of Britain, other taxa recently assigned to the family include Lapparentosaurus from the Middle Jurassic of Madagascar, and Patagosaurus from the late Early-Middle Jurassic of Patagonia, which share autapomorphies with Cetiosaurus that are not shared by other eusauropods.
• It is more robust and smooth on top; unique derived traits, autapomorphies, include long paroccipital processes and basipterygoids at the back of the skull and a jugal touching the squamosal.
• They interpreted the anatomies of the two as very similar and sharing key autapomorphies of the pygostyle.
• They interpreted the anatomies of the two as very similar and sharing key autapomorphies of the pygostyle.
• Acroplous is diagnosed by several autapomorphies (among dvinosaurs), including an internarial fenestra between the premaxillae; anteroposteriorly shortened postparietals; and interlocking mandibular symphyses formed by medially projecting prongs.
• Schoch found in 2013 Calamops to represent a valid taxon of trematosauroid temnospondyls that can be diagnosed by several autapomorphies.
• Odenwaldia is diagnosed by several autapomorphies, including (1) small orbits combined with broad interorbital distance; (2) preorbital region slender, with nasals and lacrimals narrower than frontals; and (3) dermal ornament consists of small, similarly sized polygons, but no elongated ridges.
• Despite the dorsal vertebrae, which are very similar to those of placodonts, the genus lacks many of the autapomorphies characteristic of sauropterygians and thus evolved from a different ancestor, independently adapting a marine lifestyle.
• Additionally, Amegilla is strongly characterized by several autapomorphies, including a gonostylus, the male phallic organ, that is fused to the gonocoxite, or interior region of copulation, and a curved maxillary palpus with distinctive surrounding fringe.
