Gymnogyps amplus is an extinct species of large New World vulture in the family Cathartidae. The species was first described by Loye H. Miller (1911)[1] in 1911 from a partial tarsometatarsus[2] recovered from Pleistocene cave deposits in Samwel Cave of northern California.[3] Harvey I. Fisher (1944) designated a set of plesiotypes from the Rancho La Brea which includes a cranium, rostrum, and mandible.[4]

The species is the only condor species found in the La Brea Tar Pits' Pit 10, which fossils date to "a Holocene radiocarbon age of 9,000 years."[4] The smaller, modern California condor may have evolved from G. amplus.[4]
