一个新的原鳄目鳄类，Baroqueosuchus haughtoni，产于橙子自由州的上三叠统或下侏罗纪埃利奥特组，是已知的最原始的原鳄目鳄类。方骨与后骨之间或颅方管下方无接触，颈内动脉未被封闭在单独的孔中，颅底平坦，蝶底广泛暴露于颅底。讨论了鳄目的基本诊断，并根据颅解剖学提供了一种新的诊断。
A new protosuchian crocodilian, Baroqueosuchus haughtoni from the Upper Triassic or Lower Jurassic Elliot Formation of the Orange Free State is the most primitive protosuchian crocodilian known. There are no contacts between the quadrate and opisthotic or below the crania-quadrate canal, the internal carotid arteries were not enclosed in separate foramina and the basicranium was flat, with the basisphenoid being broadly exposed on the base of the skull. The basic diagnosis of the Order Crocodilia is discussed and a new diagnosis is offered based upon cranial anatomy.
