派克鳄属（属名：Euparkeria 又名巴氏龙）是种小型史前爬行动物，生存在早三叠纪的非洲，约2亿4800万到2亿4500万年前。派克鳄不属于恐龙，但与主龙类的早期祖先的亲缘关系接近，

派克鳄是种小型动物，身长60公分长。身体修长，头部小，牙齿小呈针状。牠们是肉食性动物，可能以昆虫与其他小型动物为食。前肢指爪锐利。派克鳄拥有相当长的后肢，可能是半两足动物，能够只以后肢快速奔跑。这种能以两足运动的特征，让派克鳄成为早期两足爬行动物之一，这种特征并维持到某些恐龙与早期镶嵌踝类主龙。如同某些早期主龙类，派克鳄的背部、尾巴已有小型皮内成骨。

Euparkeria (/juːˌpɑːrkəˈriːə/; meaning "Parker's good animal", named in honor of W.K. Parker) is an extinct genus of archosauriform from the Middle Triassic of South Africa. It was a small reptile that lived between 245-230 million years ago, and was close to the ancestry of Archosauria, the group that includes dinosaurs, pterosaurs, and modern birds and crocodilians. Euparkeria had hind limbs that were slightly longer than its forelimbs, which has been taken as evidence that it may have been able to rear up on its hind legs as a facultative biped. Although Euparkeria is close to the ancestry of fully bipedal archosaurs such as early dinosaurs, it probably developed bipedalism independently. Euparkeria was not as well adapted to bipedal locomotion as dinosaurs and its normal movement was probably more analogous to a crocodilian high walk.
