Aquilarhinus (meaning "eagle nose") is an extinct genus of hadrosaurid dinosaur from the Aguja Formation in Texas. The type species, Aquilarhinus palimentus, was described in 2019.[1]


The holotype, TMM 42452-1, is represented by a sphenoid fragment, both nasals, right maxilla, right jugal, right quadratojugal, partial left and right palatines, partial right dentary, partial first ceratobranchial, partial neural arch of atlas, fragments of two cervical centra, two cervical ribs, partial sacral rib, left carpal, nearly complete left manus, postacetabular process of right ilium, fragment of right ischium, partial astragali, pedal phalanx III-1, and four pedal unguals. Most parts of TMM 42452-1 were collected in 1983 by T. Lehman, N. LaFon and K. Davies. In 1999, J. Wagner and T. Lehman continued excavation of the site, collecting additional elements.[1]
