The Sao Khua sclerorhynchoid is an unnamed genus and species of sclerorhynchoid from the Early Cretaceous Sao Khua Formation in Thailand. It is known from the tip of a rostral denticle that is deposited in the Sirindhorn Museum as SM 2012-1-021. The denticle has a single barb similar to Onchopristis, Onchosaurus, and Pucapristis, but is distinguished from all other genera by having a row of enameloid "droplets" on each side.[1] It is one of the earliest sclerorhynchoids, along with Celtipristis and Onchopristis which also appeared in the Barremian.[2]
