Spencer George Lucas is an American paleontologist and stratigrapher, and curator of paleontology at the New Mexico Museum of Natural History and Science.
His main areas of study are late Paleozoic, Mesozoic and early Cenozoic vertebrate fossils, stratigraphy, and continental deposits, particularly in the American Southwest.
In 2007, some publications by Lucas and associates at the New Mexico Museum of Natural History and Science came under scrutiny after allegations that information was improperly taken from the unpublished and in-press work of graduate students not on his team.
