Vertebrate Paleontology


The Desert Laboratory houses and curates the University of Arizona Laboratory of Paleontology (UALP) collection. The UALP collection comprises over 23,730 numbered specimens from 9,906 fossil localities, primarily from the southwestern United States, with an emphasis on Arizona, and from northern Mexico. The majority of the material is Rancholabrean (240,000 years to 11,000 years BP) with primary collections from Clovis Mammoth kill sites in the San Pedro River Valley.
