Aquilops
''Aquilops americanus'' is an early herbivorous ceratopsian dinosaur dating from the Early Cretaceous of North America, approximately 108 million to 104 million years ago.
==Discovery and naming==
In 1997, paleontologist Scott Madsen found the single fossil, a partial skull, in Carbon County in southern Montana. While preparing the specimen, at first assumed to be of ''Zephyrosaurus'', he discovered that it was a species new to science.
In 2014 the type species ''Aquilops americanus'' was named and described by Andrew Farke, W. Desmond Maxwell, Richard L. Cifelli, and Matt J. Wedel. The generic name is derived from Latin ''aquila'', "eagle", and Greek ὤψ, ''ops'', "face", in reference to the beaked snout. The specific name ''americanus'' refers to the fact that the species represents the first unequivocal very basal neoceratopsian found in America.
The holotype, OMNH (Sam Noble Museum, Norman, Oklahoma) 34557, was found in a layer of the Cloverly Formation, dating from the middle-late Albian. It consists of a skull with lower jaws, of a subadult individual. The rear of the head and the palate are the main lacking parts.〔 The specimen was found during a 1997 expedition supported by the National Geographic Society and directed by Cifelli.
