Palintropus is a genus of bird possibly closely related to Apsaravis, known from the Lance Formation of Wyoming. It lived about 69 to 66 million years ago, in the Maastrichtian age of the Late Cretaceous. It is known from only a fragment of a bone, which means its hard to say much about it, though it was probably a land-dwelling bird like Apsaravis.
