The presence of teeth in the Eunotosaurus africanus shows evolutionary relationship

Answer 1

"There was a gradual change of large, elongated ribs in the Eunotosaurus africanus into a hard shell of modern turtles."

Reason: Eunotosaurus has broadened, overlapping ribs that are interpreted as an early stage in the evolution of the turtle carapace; this morphological transition provides direct evidence of an evolutionary relationship.
