O. finneyi had well-developed wings, and could clearly fly, but lacked the enlarged cochlea of all extant echolocating bats, closely resembling the old world fruit bats which do not echolocate. [1]
The two oldest-known fossil skeletons of bats, unearthed in southwestern Wyoming and dating to at least 52 million years ago, are providing insight into the early evolution of these flying mammals ...
The delicate skeletons of bats do not fossilise well; it is estimated that only 12% of bat genera that lived have been found in the fossil record. [6] Most of the oldest known bat fossils were already very similar to modern microbats, such as Archaeopteropus (32 million years ago).
The common vampire bat, Desmodus rotundus, also has specialized thermoreceptors on its nose, [16] which aid the animal in locating areas where the blood flows close to the skin of its prey. A nucleus has been found in the brain of vampire bats that has a similar position and similar histology to the infrared receptor of infrared-sensing snakes ...
