A new, Early Cretaceous carettochelyid turtle from South Korea provides insights into softshell evolution and aquatic ecology.

In conclusion, these comparisons among Cretaceous carettochelyids yield two key insights: (1) while an overall trend of plastral expansion exists within the clade, early members may have possessed broader plastra than previously thought; and (2) the extremely narrow plastron of Kizylkumemys schultzi is likely a specialized condition, rather than the plesiomorphic trait of the group.
