始祖单弓兽属

Skull reconstruction of A. florensis

始祖单弓兽属(属名:Archaeothyris)是种早期合弓动物,生存于约3亿600万年前的石炭纪晚期。始祖单弓兽是目前已知最古老的合弓动物之一,另一属是研究有限的EchinerpetonProtoclepsydrops的生存年代略早,但其化石较为零碎,无法确定是否属于合弓类动物。

始祖单弓兽是在1972年发现于加拿大新斯科细亚,跟林蜥、油页岩蜥发现于同一地点。始祖单弓兽与其他早期蜥形纲动物的外表类似。

Archaeothyris is an extinct genus of ophiacodontid synapsid that lived during the Late Carboniferous and is known from Nova Scotia. Dated to 306 million years ago, Archaeothyris, along with a more poorly known synapsid called Echinerpeton, are the oldest undisputed synapsids known. Protoclepsydrops also from Nova Scotia is slightly older but is known by very fragmentary materials.
