No new genera this time, just a year-end summary (something new), since it's not very likely I will be adding any new names to the Dinosaur Genera List during the last few days of 2001. The latest Journal of Vertebrate Paleontology arrived here a few days ago and no new dinosaurs are described in it. During 2001, the Dinosaur Genera List grew by 35 new names (#898 through 932) altogether, of which 24 represented valid, scientifically described dinosaurs; seven were dinosaur nomina nuda published in non-scientific articles; two were names in publicly available dissertations; and two at one time or another had been considered dinosaurian but are presently not "non-avian dinosaurs" (that is, are non-non-avian dinosaurs): Scientifically described dinosaur genera (in the order added) [24]: Jeholosaurus Masiakasaurus Draconyx Eotyrannus Paralititan Losillasaurus Nothronychus (first entered as a nomen nudum but later formally described) Jinzhousaurus Quilmesaurus Venenosaurus Planicoxa Bienosaurus Ruehleia Citipati Khaan Liaoningosaurus Rapetosaurus Eshanosaurus Aletopelta Cedarpelta Hesperosaurus Jiangshanosaurus Neimongosaurus Pukyongosaurus Nomina nuda and vernacular names [7]: "Saltriosaurus" Aucasaurus "Colossosaurus" Yibinosaurus Tanycolagreus "Hanwulosaurus" Heilongjiangosaurus Nomina ex dissertationes (names from dissertations) [2]: Alashansaurus Szechuanoraptor Non-non-avian dinosaurian genera once regarded as non-avian dinosaurs [2]: Deuterosaurus Wellnhoferia In addition, two names were changed from non-avian-dinosaurian to non-non-avian-dinosaurian: Spondylosoma Patricosaurus One name was provisionally reinstated as non-avian dinosaurian, pending continuing debate and research: Shuvosaurus One name was upgraded from nomen nudum to scientifically described (as was Nothronychus): Gobisaurus One name was changed from nomen nudum to nomen ex dissertatione: Acracanthus (which is in Wann Langston's M.Sc. thesis, not in his doctoral dissertation as noted in the DGL Update) And one standalone nomen nudum became a different name when scientifically described: Bilbeyhallorum [-> Cedarpelta] Here's wishing everyone on my list of DGL Update recipients a most pleasant 2001 holiday season and brightest of prospects for the coming new year!
