"Icaronycteris" is an extinct genus of microchiropteran (echolocating)
batthat lived in the early Eocene, approximately 52.5 million years ago. Four exceptionally preserved specimens are known from the Green River Formationof North America. There is only one thoroughly described species of bat in the genus, "I. index", although fragmentary material from France has also been tentatively placed within "Icaronycteris".

"Icaronycteris" measured about 14 cm (5,5 in) long and had a wingspan of 37 cm (1 ft 3 in). It closely resembled modern bats, but had some primitive traits. The
tailwas much longer and not connected to the hind legs with a skinmembrane, the first wing finger bore a clawand the body was much more flexible. Like modern bats, "Icaronycteris" slept while hanging upside down, holding onto a treebranch or stone ridge with its hind legs.
"Icaronycteris" was featured as an enemy in the
2000game adaptation of Walt Disney Pictures's "Dinosaur".
