Dinosaur Genera List update #196

[Dinogeorge@aol.com]

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!
