Make a wish on this Fossil Friday, you’re looking at a T. rex wishbone!
Wishbones, or furculae, are extremely diverse in size and shape. For years, scientists thought the bone strengthened the body for the demands of flight. But the cast of this furcula fossil belonged to a decidedly earthbound dinosaur, Tyrannosaurus rex. Bottom line: the furcula is unconnected to the origin of flight.
Learn much more about the origins of flight in the new exhibition, Dinosaurs Among Us, now open!
