TITLE: Gravemys Sukhanov and Narmandakh, 1983 (Testudinoidea: Lindholmemydidae) from the Late Cretaceous of Asia: new data
AUTHOR: Igor Danilov
JOURNAL: PaleoBios
NOTES: 23(3)
ABSTRACT: The study of new specimens of Gravemys barsboldi, a rare lindholmemydid turtle from the Late Cretaceous of Mongolia, reveals new details regarding its morphology. These include a clear overlapping of marginal 12 onto suprapygal 2, inguinal buttress reaching the two thirds of the width of costal 5 and contacting the costals 5-6 suture laterally, variably shaped inframarginals and viability (straight or sinuous) medial pectoral sulcus. Gravemys hutchisoni, sp. n., is based on the paratype specimen of Mongolemys trufanensis Yeh, 1974, from the Late Cretaceous of Turfan (Xinjiang, China). This new assignment is based on the similarity in shape of the plastral lobes, the presence of four pairs of inframarginals that strongly onlap the peripherals, and a shortened entoplastron.
