Sahonachelys is an extinct genus of pelomedusoid turtle from the Late Cretaceous (Maastrichtian) Maevarano Formation of Madagascar.

[1] Sahonachelys is a genus of small pelomedusoid turtle, that existed in what is now Madagascar during the Maastrichtian epoch approximately 72.1 to 66 million years ago.

It had a flattened skull and particularly small and gracile jaw giving its head an almost frog like appearance in life.

This specialized feeding adaptation has not been documented within any other crown pelomedusoid illustrating the uniqueness of the Madagascan fauna during the Cretaceous, and ways they evolved within isolation from the rest of the planet during this time.
