Dinosaur Genera List update #197



Although I didn't think I'd be adding any more dinosaur names to the Dinosaur 
Genera List during the last few days of 2002, two more did in fact arrive. 
The first was in an email from Alex Kellner:

"Thanks for the email. I just would like to update the list with a new 
theropod (Abelisauria) from the Bauru Group (Late Cretaceous, Brazil):

Pycnonemosaurus nevesi Kellner & Campos 2002

I wish you all the best for 2003."

So far I have no citation for this name, but Alex subsequently said he'll be 
sending an offprint shortly. In the meantime, it becomes name #964:

Pycnonemosaurus Kellner & Campos, 2002

The second appears at a website

http://www.dvuch.febras.ru/article.php?n=16

which is the online version of a popular-science article evidently published 
in a little-known, fairly new Russian periodical. Here is the citation:

Bolotsky, Yu., Alifanov, V. & Godefroit, P., 2002. "Gigantskii lebed' iz 
Arkhari: 100 lyet amurskim dinosavram [Giant swan from Arkharin: 100 years of 
Amur dinosaurs]," Dal'nevostochnii Uchonii [Far-Eastern Scientist] #16: 
pagination not available [in Russian, August 21, 2002].

The article summarizes dinosaur discoveries in far-eastern Russia since 1902. 
The new dinosaur comes from the Tsagayanskaya Svita (same formation as 
Amurosaurus), a new locality called Kundur, in the Arkharin region, Amurskaya 
Oblast. It is represented by an articulated partial skeleton discovered 
during a highway excavation in 1999 and collected over a period of three 
years. The name unveiled in the article is Olorotitan archarensis Bolotsky & 
Godefroit. It is a hadrosaur about 12 meters long and it may have had an 
uncrested head (assuming the name Olorotitan is meant to show some close 
relationship to North America's Anatotitan). I don't know whether skull 
material is available. Olorotitan is not formally described in the article, 
and as I have no citation for a scientific description, it is listed in the 
Dinosaur Genera List, #965, as a nomen nudum:

Olorotitan Bolotsky & Godefroit vide Bolotsky, Averianov & Godefroit, 2002 [
nomen nudum]

The article also uses the well-known Greg Paul picture of an albertosaur 
attacking some corythosaurs to show what kinds of dinosaurs the latest 
Cretaceous Amur region might have supported, but calling the corythosaurs 
Amurosaurus. (This in turn suggests that the as-yet-undepicted Amurosaurus 
was a crested hadrosaurian similar to Corythosaurus in external appearance.) 
The tyrannosaurid is an unnamed form smaller than Tarbosaurus but bigger than 
Maleevosaurus. A cervical series was discovered that indicates it had an 
unusually strongly S-curved neck. The authors suggest it was a close relative 
of the tyrannosaurid Alioramus.

There's not enough information about these two new dinosaurs available for me 
to construct anything more than place-keeping entries for the species in The 
Dinosaur Catalogue, so I won't transmit them at this time.
