New Specimens of ‘Crocodylus’ Pigotti (Crocodylidae) from Rusinga Island, Kenya, and Generic Reallocation of the Species
JOURNAL OF VERTEBRATE PALEONTOLOGY(2013)
Abstract
'Crocodylus' pigotti is a relatively small crocodylid from the Miocene of Rusinga Island in Lake Victoria, Kenya. Known only from one relatively complete skull and limited, fragmentary, referred material, 'Crocodylus' pigotti lacks a detailed description. Moreover, recent analyses have shown 'Crocodylus' pigotti to be an osteolaemine crocodylid, more closely related to the extant dwarf crocodiles (Osteolaemus) than to true Crocodylus. Here, we describe numerous new remains of 'Crocodylus' pigotti recovered from localities within the Fossil Bed Member of the Hiwegi Formation at Kaswanga Point, Rusinga Island. We recovered parts of several individuals and report on previously unknown parts of the anatomy, provide an updated phylogenetic analysis, and reallocate the species 'Crocodylus' pigotti to a new genus, Brochuchus.
