Lonely Are The New Papers



...'cuz there's only one this time 'round:

Läng, E., and Goussart, F. 2007. Redescription of the wrist and manus of
?Bothriospondylus madagascariensis: new data on carpus morphology in
Sauropoda. Geodiversitas 29(4):549-560

ABSTRACT: Except for some rare exceptions, the arrangement of the carpus
remains poorly understood among sauropodomorphs, mainly because of a bad
preservation in the fossil record. When preserved, it is difficult to
identify the carpal elements, which are rarely found in articulation.
Whereas the carpus of Prosauropoda is relatively well known by the remains
of Massospondylus and Plateosaurus, the structure of the sauropod carpus is
still unknown and subject to many interpretations so far. Here, we
redescribe the manus and the wrist of ?Bothriospondylus madagascariensis, a
Bathonian (Middle Jurassic) sauropod from the Majunga Basin in Madagascar,
previously described by Lavocat in 1955. The wrist consists of five carpal
elements, an unusual disposal among sauropods, which typically preserves
most of the time three or fewer carpal bones. Moreover, these five carpal
elements are arranged in three carpal rows, another unexpected feature
regarding to other sauropods. The comparison of the Malagasy carpus with
that of an hypothetical basal archosaur leads us to propose a new hypothesis
of homology for the carpus of ?Bothriospondylus. Therefore, this specimen
would consist in: a radiale, the fused distal carpal 1 with the intermedium
and one or two centrales, and three distal elements (distal carpal 2, distal
carpal 3, and distal carpal 4 or distal carpal 4 + ulnare).

"There's a saying that goes 'people who live in glass houses shouldn't throw
stones'... OK. How about...NOBODY should throw stones. That's crappy
behavior! My policy is 'no stone-throwing regardless of housing situation.'
There's an exception, though. If you're TRAPPED in a glass house...and you
have a stone, then throw it! What are you, an idiot? It's really 'ONLY
people in glass houses should throw stones'... provided they're trapped, in
a house... with a stone. It's a little longer, but you know..."
