Enaliornithidae
Enaliornis
Extinct genus of birds
Enaliornis is a genus of hesperornithine which lived during the late Albian to the early Cenomanian, making them the oldest known hesperornithines.[2] Fossils have been found near Cambridge, England. Due to its lack of certain[clarification needed] hesperornithid apomorphies, they were much more "conventional" birds and were initially held to be Gaviiformes (loons/divers).[3]
