A probable skeleton ofIsisfordia(Crocodyliformes) and additional crocodyliform remains from the Griman Creek Formation (Cenomanian, New South Wales, Australia)

Abstract

AbstractThe sparse record of Cretaceous crocodyliforms in Australia comprises only three species, all within the genusIsisfordia. Isisfordia duncaniSalisbury et al., 2006 is from the Albian–Turonian Winton Formation of Queensland, and bothIsisfordia molnariHart et al., 2019 andIsisfordia selaslophensisEtheridge, 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 toIsisfordiacf.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 withIsisfordia.
