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
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 [
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.
