A few more...
A few more refs for your consideration but I'd first like to
say that I prefer political stuff, especially the stuff that includes
labeling people and organizations with inflamatory words, be kept
off the list. Yes, its germaine to talk about the facts of Sue's
history but for all the inflamatory stuff on various stuff, try
to give it a rest or do it person to person. I don't have the time
for it. JP Turok Lost World all seem relevant to me and break up
I see in the SVP abstracts - they are overwhelming - that Greg Paul
and Ruben will be able to square off in person. O joy.
Now we start with a paper on the soft-shell turtles of the Judith River
Gardner, J.D., A.P. Russell & D.B. Brinkman. 1995. Systematics and
taxonomy of soft-shelled turtles (Family Trionychidae) from the
Judith River Group (mid-Campanian) of North America.
Canadian J. Earth Sciences 32:631-643.
The title says it all (there are 4 valid spp.). All power to our
Chelonian-American allies (pseudo political statement).
Then the latest issue we've gotton of Palaeontologia Africana has some
fun stuff (volume 31, 1994):
Gow, C.W. 1994. New find of Diarthrognathus (Therapsida: Cynodontia)
after seventy years. pp. 51-54. Scraps but interesting.
Shishkin, M.A. & J. Welman. 1994. A new find of Trematosuchus (Amphibia,
Temnospondyli) from the Cynognathus zone of South Africa. pp. 39-49.
A decent head that clarifies some things about the genus.
Juul, Lars. 1994. The phylogeny of basal archosaurs. pp. 1-38.
This is a biiiiig paper with lots of cladograms purporting to build on
new characters and old characters (both as was and modified). Supports
the monophyly of archosaurs, what he refers to the crown-group archosauria
(with the Crurotarsi & Ornithodira as monophyletic groups within)
The Crurotarsi includes a trichotomy with one group that has the
prestosuchids and Stagonolepidae, the Parasuchia the second, and a new
third group - the Dromaeosuchia - which includes the Ornithosuchidae
and the Paracrocodylomorpha (Crocodylomorpha plus Gracilisuchus and
Postosuchus). The Ornithodira includes the pterosaurs as a sister to
the Dinosauriformes which consists of Lagosuchus plus the Dinosauria.
The Dinosauria has the Ornithischia as a sister group to the Saurischia
which is defined as the Sauropodomorpha plus the Theropoda. The Theropoda
is Herrerasaurus plus the node labeled Ceratosauria +Tetanurae (take it away
Tom). There's lots of details there but that's too much for now.
