Borogovia (meaning borogove, which is a fictional creature from Lewis Carroll's "Jabberwocky") is a Troodontid from late Cretaceous Mongolia, which lived from 70 to 65 million years ago. It was about 6.6 feet (2 meters) long and weighed about as much as a beaver. Known from hind-limb material, and thought by some to be a species of Saurornithoides. It had a similar appearance to that of the Dromaeosauridaes.
