Sinaspideretes is an extinct genus of turtle from the Late Jurassic of China, probably from the Shaximiao Formation. It is considered the earliest and most basal representative of the Trionychia,[1][2] and is possibly the oldest known member of Cryptodira.[3] In 2013, it was proposed that this animal and the genus Yehguia are in fact one and the same.[4]
