Nectridea: Difference between revisions

'''Nectridea''' is the name of an extinct order of [[lepospondyl]] [[tetrapod]]s from the [[Carboniferous]] and [[Permian]] periods, including animals such as ''[[Diplocaulus]]''. In appearance, they would have resembled modern [[newt]]s or aquatic [[salamander]]s, although they are not amphibians.<ref>{{cite web|last1=Laurin|first1=Michael|title=Phylogeny of Stegocephalians|url=http://tolweb.org/articles/?article_id=467|website=Tree of Life|publisher=Tree of Life Web Project|accessdate=1 February 2017}}</ref><ref>{{cite web|title=Palaeos: Vertebrates: Lepospondyli: Overview|url=http://palaeos.com/vertebrates/lepospondyli/|website=Palaeos|accessdate=1 February 2017}}</ref>. They had long, flattened tails to aid in swimming, and well-developed hind limbs, with a full set of five toes each. Their forelimbs were somewhat reduced, however, and like [[lissamphibia|modern amphibians]], typically had only four toes each.<ref name=EoDP>{{cite book |editor=Palmer, D.|year=1999 |title= The Marshall Illustrated Encyclopedia of Dinosaurs and Prehistoric Animals|publisher= Marshall Editions|location=London|page= 54|isbn= 1-84028-152-9}}</ref>
