本文对塔斯马尼亚诺克洛夫提组(早三叠世)的一种齿状爬行动物Tasmaniosaurus triassicus进行了重新解释。塔斯马尼亚龙与著名的齿齿龙相似，属于原齿亚目原齿龙科。它的头骨是在相当标准的原脊椎动物线条上建造的，没有证据支持早先的说法，即塔斯马尼亚龙是一种异常长鼻子的爬行动物，与植物龙相似。来自昆士兰Arcadia组(早三叠世)的第二种澳大利亚齿龙Kalisuchus rewanens也属于Proterosuchidae科，但在鼻子结构上与Tasmaniosaurus不同，应作为一个单独的属保留。讨论了澳大利亚齿龙的关系，并提出了塔斯马尼龙和长尾龙的新的头骨重建。
This paper presents a reinterpretation of Tasmaniosaurus triassicus, a thecodontian reptile from the Knocklofty Formation (Early Triassic) of Tasmania. Tasmaniosaurus resembles the well-known thecodontian Chasmatosaurus and is included in the family Proterosuchidae (suborder Proterosuchia). Its skull is constructed on fairly standard proterosuchian lines, and there is no evidence to support the earlier suggestion that Tasmaniosaurus was an unusually long-snouted reptile showing resemblances to phytosaurs. A second Australian thecodontian, Kalisuchus rewanensis from the Arcadia Formation (Early Triassic) of Queensland, is also included in the family Proterosuchidae, but differs from Tasmaniosaurus in the structure of the snout and should be retained as a separate genus. The relationships of the Australian thecodontians are discussed, and new reconstructions of the skull are presented for Tasmaniosaurus and Kalisuchus.
