Sinaspideretes

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]
