A chordate is an animal of the phylum Chordata (/kɔːrˈdeɪtə/). All chordates possess, at some point during their larval or adult stages, five synapomorphies, or primary physical characteristics, that distinguish them from all the other taxa. These five synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and a post-anal tail. The name “chordate” comes from the first of these synapomorphies, the notochord, which plays a significant role in c… WebPareiasauromorpha is a group of parareptilian amniotes from the Permian.It includes genera found all over the world, with many genera from Asia and South Africa.The clade was first used as a group by Linda A.
