No new genera this time, just my second year-end summary. It's not very likely I will be adding any new names to the Dinosaur Genera List during the last few days of 2002. During 2002, the Dinosaur Genera List grew by 31 new names (#933 through 963), of which only 14 represented valid, scientifically described dinosaurs; eight were dinosaur nomina nuda published in non-scientific articles; two were names in publicly available dissertations; and seven at one time or another had been considered dinosaurian but are presently not "non-avian dinosaurs" (that is, they are non-non-avian dinosaurs): Scientifically described dinosaur genera (in the order added) [14]: Agnosphitys Megapnosaurus (replacement name for Syntarsus, preoccupied) Sinovenator Liaoceratops Hylosaurus (junior synonym of Hylaeosaurus) Shenzhouraptor Jeholornis Erliansaurus Cryptovolans Omnivoropteryx Scansoriopteryx Incisivosaurus Epidendrosaurus Crichtonsaurus Nomina nuda and vernacular names [8]: "Huaxiasaurus" "Ichabodcraniosaurus" Gavinosaurus (vernacular synonym of Eotyrannus) Lengosaurus (vernacular synonym of Eotyrannus) Crosbysaurus (scientific description in the works) Protecovasaurus (scientific description in the works) Byranjaffia (vernacular synonym of Byronosaurus) Silesaurus (scientific description in the works) Nomina ex dissertationes (names from dissertations) [2]: Equijubus Gobititan Non-non-avian dinosaurian genera once regarded as non-avian dinosaurs [7]: Palaeosaurus Eurolimnornis Limnornis Palaeocursornis Palaeolimnornis Sphenosaurus Archaeovolans (junior synonym of Yanornis) One name was upgraded from nomen nudum to scientifically described: Aucasaurus For Arundel paleopersons: In compiling The Dinosaur Catalogue, when I reached Allosaurus medius I discovered several anomalies and inconsistencies in the literature on Arundel Formation theropods. So I carefully went over the relevant articles (primarily Lull, 1911 and Gilmore, 1920) and I believe I now have all the specimen numbers straight. Some of the species names will have to be changed, which I'll do in either The Dinosaur Catalogue or the second printing of Mesozoic Meanderings #3, whichever is ready first. I have prepared a short table of specimens, mainly at the US National Museum, currently referable to Arundel theropod species (it excludes specimens currently referred to unnamed Arundel theropod species), and anyone who would like to review this table (additions and corrections most welcome) please contact me off list. Here's wishing everyone on my list of DGL Update recipients a most pleasant 2002 holiday season and brightest of prospects for the coming new year!
