 In 2007 , paleontologists at the New Mexico Museum of Natural History and Science in Albuquerque , New Mexico were accused of plagiarism in some of their published articles dealing with aetosaurs . In late 2006 , the genus Rioarribasuchus was erected as a replacement name for " Desmatosuchus " chamaensis in the museum 's bulletin . However , four years earlier paleontologist William Parker reassigned " D. " chamaensis to the newly named genus Heliocanthus in an unpublished thesis . Because the name was not published , it was considered a nomen nudum until 2007 when it was described in the Journal of Systematic Palaeontology . The authors of the 2006 paper , Spencer G. Lucas , Adrian P. Hunt , and Justin A. Spielmann , were accused of " intellectual theft " by paleontologists Jeff Martz , Mike Taylor , Matt Wedel , and Darren Naish , who claimed that they knew that Parker was eventually going to redescribe the species and formally erect a new genus . According to Martz , Taylor , Wedel , and Naish , the authors rushed to publish their own name before Parker could publish his .
