Richardoestesia is a medium sized (~100 kg) genus of theropod dinosaur from the late Cretaceous Period of what is now North America. It is known from a single pair of lower jaw bones and a large number of isolated teeth. The jaws are slender and rather long but the teeth are small and finely serrated. It has been suggested that Richardoestesia was a fish eater, like a heron. Because so little is known of the animal, its relationships are unclear. However, the jaws resemble Archaeopteryx, Troodontidae and some Dromaeosauridae, in having a strong groove on the lateral surface. The jaws and a number of teeth come from Dinosaur Provincial Park but Richardoestesia teeth are also found in the Late Cretaceous Horseshoe Canyon Formation, and the Scollard Formation. Its teeth are extremely common in the Lance Formation. Paronychodon teeth may come from Richardoestesia. The genus is named for Richard Estes, to honor his important work on the small vertebrates of the Late Cretaceous.
