Manchurochelys liaoxiensis, fossil turtle Ouranosaurus The first Odonata fossils wereManchurochelys liaoxiensis, also known as Ordosemys liaoxiensis, is described as a cryptodire (a turtle order), with a very low domed shell. The carapace, shell, had an oval outline, with the length being slightly longer than the width. Manchurochelys liaoxiensis looked like a modern turtle, but it was a primitive turtle and could not draw its head or legs into its shell. It likely fed on plants, small fish, and insects present in its environment.
