from Wikipedia, the free encyclopedia

Spencer George Lucas (* before 1976) is an American paleontologist and curator of paleontology at the New Mexico Museum of Natural History and Science (NMMNHS).

life and work

Lucas graduated from the University of New Mexico with a bachelor's degree in 1976 and Yale University , where he received his PhD in 1984. His dissertation was entitled Systematics, biostratigraphy and evolution of early Cenozoic Coryphodon (Mammalia, Pantodonta) . He began his field work in 1976 in the Eocene (San Jose Formation) of the San Juan Basin in New Mexico with mammalian fossils, which he extended to Cretaceous and Paleocene in the following year . Since 1988 he has been the curator of geology and paleontology at the New Mexico Museum of Natural History and Science in Albuquerque .

He is concerned with stratigraphy and vertebrate paleontology of terrestrial vertebrates of the Paleozoic, Mesozoic and Cenozoic Era, particularly in the American Southwest. He also excavated in northern Mexico, Costa Rica, Nicaragua, Jamaica, Kazakhstan, Georgia, and the People's Republic of China.

In 2008 an article appeared in Nature accusing him (and his colleagues Adrian Hunt and Justin Spielman from the NMMNHS) of scientific misconduct (evaluation of research results from younger colleagues before publication). It was about ancestors of the dinosaurs from the Aetosauria group and a suggestion for a name for a species of the group (Rioarribasuchus), although a colleague (William Parker, Petrified Forest National Park) also wanted to submit a proposal (Lucas denied having known about it). He was also accused of describing aetosaur fossils from the Paleontological Institute of the University of Warsaw after his visit, although colleagues there were working on a publication about them (a misunderstanding according to Lucas) and there were also allegations regarding a reinterpretation of the skeleton of Redondasuchus, where he should not have adequately cited a master's thesis (Jeff Martz, Texas Tech). Lucas benefited from the fact that he mainly published in his museum's in-house journal (New Mexico Museum of Natural History and Science Bulletin) and thus avoided time-consuming peer reviews. Lucas is the editor of the magazine. He published well over 500 scientific papers. In 2007, the allegations led to an official letter of complaint to the New Mexico education authorities and the Ethics Committee of the Society of Vertebrate Paleontology.

He published on Seismosaurus , Pentaceratops , Chasmosaurus , Ankylosaurier and Deinosuchus , on fossil tracks (track sandstone ) and on the origin of the turtle shell (find by Chinlechelys , see Osteoderm ).

In 2007 he presented 300-million-year-old impressions of the bodies of amphibians (boneless remains) that a student had previously found in the collections of a museum in Pennsylvania.

1973/74 he was chess master of New Mexico. He is a member of the New Mexico Academy of Sciences.
