Distinguished by a palate that was closed with the air passages being separated from the food passages, a long and flat skull with large openings, numerous pointed teeth along the margins of the jaws, a slender body, long neck and tail, and long limbs. Although the animal was aquatic, the limbs were less specialized for swimming than they were in more advanced sauropterygians. ]]></termNote><termCreatedDate>2026-03-30 20:57:36</termCreatedDate><relation><relationType>UF</relationType><termId>31436186</termId><termName>nothosaur</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31436187</termId><termName>nothosaurs</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31409597</termId><termName>Diapsida</termName><termType>PT</termType></relation></term>  </Zthes>
