Apsaravis ("Apsara Bird") is an extinct genus advanced short-tailed Avialian from late Cretaceous Mongolia. The type and only species is A. ukhaana.


Apsaravis is the most basal bird that has evidence of an extensor process, which is key when figuring out the flight stroke of modern day birds. Apsaravis also has multiple bones attributed to it, such as: vertebrae, a pubis and ischium that are closely appressed, a femur, an illium, and many more. It was a small bird, with a length of 18 centimeters and a wingspan of 30 centimeters. It also had long legs with long feet and stout toes.


The discovery of Apsaravis was important in paleontology since it showed that not all basal birds were oceanic or shoreline dwelling animals, as it was found in a sand dune environment. Apsaravis had to live with one of the most famous theropods, Velociraptor, while also living with some other important creatures in paleontology, being Protoceratops and Pinacosaurus. Apsaravis likely hunted lizards and other small animals in its enviroment.
