Khok Kruat Formation

The Khok Kruat Formation (Thai: หมวดหินโคกกรวด) is a rock formation found in northeastern Thailand. It is the uppermost formation of the Khorat Group.[1] It is dated to the Aptian stage of the Early Cretaceous period, and is notable for its fossils of dinosaurs. It is equivalent to the Gres superieurs Formation of Laos.[2] The group is a fluvial formation consisting primarily of red siltstones and sandstones.[1]

Vertebrate paleofauna

The Khok Kruat Formation has yielded remains of sharks, fishes, turtles, crocodilians and pterosaurs. Phuwiangosaurus-like teeth, Siamosaurus teeth, and fragmentary postcranial remains of spinosaurids have also been recovered from it.[3] Fukuiraptor-like teeth have also been recovered from the formation.[4]
