I'm not quite 17 yet, but I'm pretty sure that I want to be a
paleontologist after college (and, during, I guess). I think this mailing list
is a great opportunity to have scientific discussions and increase general
knowledge of dinosaurs. Mostly I plan on watching and learning from the
*experts*, but I won't hesitate to ask questions if I have any. And, oh look
-- here's one now!
I've been looking at various cladograms available on the web (Mike
Keesey's and Stan Friesen's, mostly) and they both seem to say that all Lancian
tyrannosaurs of North America should be included in Tyrannosaurus. This
includes Nanotyrannus lancensis and Dinotyrannus megagracilis. Also, they say
Maleevosaurus novojilovi should be in included in T. bataar or T. efremovi
(what's the diff between these two, anyway?). I would like to know the popular
opinion on this theory. Is this widely accepted, or a "heresy" (a la Bakker)?
Are they simply growth stages, or can they be put in subgenuses of
Tyrannosaurus? And if the former, I'd like to know where that was published,
if it has been. (Sorry, just curious, didn't mean to sound rude.) I thought I
read somewheres that the Nanotyrannus skull was from an adult. Or maybe I just
like the idea of "pygmy" tyrannosaurs running around. But that's just a
fetish...um, never mind.
I'm probably sounding like an idiot right now, but sorry, I don't have
access to much more than Science, and I can make a trip to the U of Houston
library if I need to find Nature, but those other obscure journals are pretty
tough for a high school junior to get a hold of. And I probably am making
gross anatomical errors in my judgement, but I had to teach myself dinosaur
anatomy using "The Dinosauria", so I may actually be clueless.
Oh yes, one more thing on the subject of tyrannosaurs. In Horner's
"The Complete T. rex", he mentions 4 undescribed species: a "stretch-snouted"
daspletosaur, a Horseshoe Canyon (?)daspletosaur, a non-Albertosaurus libratus
, and a Tyrannosaurus/Daspletosaurus intermediate. Anybody know what's up with
these guys? It's been 5 years since the book came out.
