The Elements of Evolution (21-13-1) Anurognathus


Anurognathus was a small pterosaur, the size of a swift. Its legs were stronger than any bird or bat alive today.

Some birds, such as swifts, chase insects through the sky: a technique termed hawking; not Anurognathus. Instead, it sat in wait for its prey to fly by, then Anurog-nathus instantly launched itself on an intercept course, which is called sallying. Anurognathus‘ powerful legs let it leap into the air, losing no time, nor wasting energy, on hawking about.
