The sparse record of Cretaceous crocodyliforms in Australia comprises only three species, all within the genus Isisfordia. Isisfordia duncani Salisbury et al., 2006 is from the Albian–Turonian Winton Formation of Queensland, and both Isisfordia molnari Hart et al., 2019 and Isisfordia selaslophensis Etheridge, 1917 have been described from opalized material from the Cenomanian Griman Creek Formation of New South Wales. Here, we describe new cranial and postcranial material, including the most complete crocodyliform skeleton from the Cretaceous of New South Wales, which is assigned to Isisfordia cf. I. selaslophensis. We also reappraise previously described crocodyliform material from the same locality. We find that much of this material displays features that are consistent with Isisfordia.

可能的 Isisfordia (Crocodyliformes) 骨骼和来自 Griman Creek 组 (Cenomanian, 新南威尔士州, 澳大利亚) 的其他鳄鱼遗骸

澳大利亚白垩纪鳄鱼类的稀少记录仅包括三个物种,都在该属内伊西斯福尔迪亚。荸荠Salisbury 等人,2006 年来自昆士兰的 Albian-Turonian Winton 组,两者均石菖蒲Hart 等人,2019 年和鸢尾花Etheridge, 1917 描述了来自新南威尔士州 Cenomanian Griman Creek 组的蛋白石化材料。在这里,我们描述了新的颅骨和颅后材料,包括新南威尔士白垩纪最完整的鳄鱼骨骼,该骨骼被分配到伊西斯福尔迪亚参看。I. selaslophensis. 我们还重新评估了来自同一地点的先前描述的鳄鱼形材料。我们发现这些材料中的大部分都显示出与伊西斯福尔迪亚.
