Turtle Remains from Koh Moul (SW Cambodia) and Their Stratigraphical Implications
Diversity 18(5): 249

This study reports on the first Mesozoic turtle remains from Cambodia. The material, consisting of shell fragments, was collected at Koh Moul, an island in the Gulf of Thailand. These turtle remains are assigned to Trionychoidae indet. and have strong similarities with the Early Cretaceous basal trionychoid Basilochelys macrobios from the Khorat Group, NE Thailand. The discovery suggests an Early Cretaceous age for the fossil-bearing strata.

Temnodontosaurus, a large ichthyosaur from the Early Jurassic, was one of the first ichthyosaurs to be scientifically described as early as the 19th century. Over time, various large Toarcian ichthyosaurs have been referred to Temnodontosaurus, a genus that is currently considered non-monophyletic. We describe a partial neoichthyosaurian skeleton from the Upper Toarcian, Jurensismergel Formation, Levesquei Zone, in Mistelgau, Germany. The specimen UMO BT 011237.00 comprises exceptionally well-preserved, three-dimensional cranial and mandibular elements, pectoral girdle, both forefins, anterior vertebral column, postflexural centra, over 100 teeth and four gastroliths. The study presents previously undescribed details in the morphology of the premaxilla, palate, scleral plates, dentition, and forefins. The described specimen matches all examined characteristics of the generic diagnosis of Temnodontosaurus. Due to some morphological differences and a slightly younger stratigraphic age than Temnodontosaurus trigonodon as well as the required taxonomic revision, we use open nomenclature and refer the specimen to Temnodontosaurus cf. trigonodon. Pathologies primarily affecting the pectoral girdle and mandibular joint likely influenced the animal’s hunting and feeding behaviour, resulting in abraded teeth and the presence of gastroliths. The specimen confirms the presence of Temnodontosaurus in the Southwest German Basin during the late Toarcian.
