This weeks #Lego #FossilFriday is #Megalonyx

The first fossils of a large animal were found in a cave in 1796 by Colonel John Stuart. He sent them to Thomas Jefferson as he was getting ready to become president.

Jefferson examined the femur fragment, ulna, radius and foot bones, including three large claws and wrote a paper about them. He named the animal Megalonyx from the Greek "Mega" (giant) and "Onyx" (claw).

In 1799 Caspar Wistar identified them as the remains of a Giant Ground Sloth
