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.
Tong et al. (2026) studied this question.
