First, assume billions of years. Second, assume evolution is a fact. Third, ignore the variety of past and present forms of turtles. Fourth, forget about the amazing engineering of their shells. Fifth, do not take into account relevant data and alternative explanations. Sixth, do not even consider the possibility that God is the creator, and that's why there is no actual evidence for evolution.
Other than those small details, sure, they lassoed themselves a transitional form. Yee ha.
Pappochelys, whose name means “grandfather turtle,” is the latest fossil to be called a “transitional form” or “missing link” in turtle evolution. (The last one was Eunotosaurus, which we discussed in “Turtle in the Gap.” Before that it was Odontochelys, discussed in “A Sea of Change for Turtle Origin Theories.”)To read the rest, click on 'Is “Grandfather Turtle” the Transitional Form that Puts Creationist Claims to Rest?'
Pappochelys was found in Germany’s Middle Triassic Lower Keuper formation. It has an unusual skull and lacks a fused shell. Evolutionary scientists believe Pappochelys appeared 240 million years ago as a transitional step in the evolution of the turtle shell. The authors of the study describing “grandfather turtle” also believe its skull confirms that turtles evolved millions of years ago from lizard-like reptiles.
