Spencer G. Lucas
U.S. palaeontologist

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. His research has taken him on field trips to northern Mexico, Costa Rica, Nicaragua, Jamaica, Kazakhstan, and Georgia, and he conducted extensive field and museum research in China in the 1980s and 1990s. He has written more than 500 scientific contributions (about 25-percent are articles in peer-reviewed journals), three books, and has co-edited 14 books.
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of Natural History and Science came under scrutiny after allegations that information was improperly taken from the unpublished and in-press work of graduate students not on his team. Formal complaints were made to the New Mexico Department of Cultural Affairs regarding publications on a new genus of aetosaur (a type of armored prehistoric reptile from the Triassic), and a reinterpretation of another aetosaur's armor. In July 2008, the Ethics Committee of the Society of Vertebrate Paleontology concluded that the matter could not be resolved in favor of either side.
In 2012, he co-authored a paper describing the world's smallest tetrapod footprints, found at Joggins, Nova Scotia.
Lucas was a master-level chess player (New Mexico state champion in 1973 and 1974). He gave up chess, for the most part, in the mid-1970s to focus on his academic career.

Why this record matters
“Spencer G. Lucas” is worth following because a concise public description often conceals a longer documentary argument. Here, Spencer, Lucas and palaeontologist provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q3820304. VIAF identifies the subject as 34146332915018731874. The Library of Congress control number is n80151870. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2007, 2008, 2012 and 1973.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
