Abstract
Two new species of geoemydid turtles from the late Eocene - early Oligocene of Krabi Basin in southern peninsula of Thailand are described on the basis of shells and other posteranial material: Mauremys thanhinensis n. sp. and Hardella siamensis n. sp. These early representatives of testudinoid turtles from South-East Asia shed light on the early evolution of extant geoemydids.
