How archosauromorphs beat out therapsids

From: Ben Creisler

Two news story links about a new study of how archosauromorphs beat
out therapsids and reached huge size.
The official article has not been posted yet on the Proceedings of the
Royal Society B site:

Re: How archosauromorphs beat out therapsids

wow, interesting to see how the Discovery News story mention all the
key points found by our sauropod research group FOR 533 (see
http://onlinelibrary.wiley.com/doi/10.1111/j.1469-185X.2010.00137.x/full
and http://www.iupress.indiana.edu/product_info.php?products_id=317633),
and totally fails to mention that all that has already been
extensively published. Matt Wedel's, Daniela Schwarz's and several
other people's research on pneumaticity and the implication of it for
body size is also presented as if Sookias came up with it.....
hmmm..........

I am eagerly looking forward to perusing the paper's reference list.

Also - extrapolating from femur length ONLY?????? How 1990 can you
design your study?

Re: Neoplateosaurus--most preposterous tabloid dinosaur ever?!

Awesome.

I'm almost disappointed by the mention of the Laptev Sea, which really exists.

Here's the official citation:

Roland B. Sookias, Richard J. Butler and Roger B. J. Benson (2012)
Rise of dinosaurs reveals major body-size transitions are driven by
passive processes of trait evolution.
Proceedings of the Royal Society B (advance online publication)
doi: 10.1098/rspb.2011.2441
http://rspb.royalsocietypublishing.org/content/early/2012/01/31/rspb.2011.2441.abstract

The pdf of the data supplement is free:
http://rspb.royalsocietypublishing.org/content/suppl/2012/01/31/rspb.2011.2441.DC1/rspb20112441supp2.pdf

A major macroevolutionary question concerns how long-term patterns of
body-size evolution are underpinned by smaller scale processes along
lineages. One outstanding long-term transition is the replacement of
basal therapsids (stem-group mammals) by archosauromorphs, including
dinosaurs, as the dominant large-bodied terrestrial fauna during the
Triassic (approx. 252–201 million years ago). This landmark event
preceded more than 150 million years of archosauromorph dominance. We
analyse a new body-size dataset of more than 400 therapsid and
archosauromorph species spanning the Late Permian–Middle Jurassic.
Maximum-likelihood analyses indicate that Cope's rule (an active
within-lineage trend of body-size increase) is extremely rare, despite
conspicuous patterns of body-size turnover, and contrary to proposals
that Cope's rule is central to vertebrate evolution. Instead, passive
processes predominate in taxonomically and ecomorphologically more
inclusive clades, with stasis common in less inclusive clades.

Re: How archosauromorphs beat out therapsids

Interestingly, much of what is verbatim quotes in the press is not
touched upon in the paper at all. And that stuff comes across, in the
press, as being results of the study, when in fact it is old news.

Me = not happy.

Re: Jack Horner married

Isn't there some kind of professional breach of ethics here. Do professors get to "dip in the pool" to get
dates? Isn't that wrong?

Let me know. (I suppose this might be off topic, but they are both in paleontology)

Sorry Dr Horner.

Plateosaurus: the Etymology and Meaning of a Name

From: Ben Creisler
bcreisler <at> gmail.com

My apologies to the DML for the length of this posting--I don't have a
blog of my own. Confusion over the etymology and the meaning of the
name Plateosaurus has been fairly common. In particular, the English
language and the German language Wikipedia articles currently give an
incorrect meaning for Plateosaurus that has spread around the web. I
hope this discussion helps clear up the issue.

Etymology and Meaning of the Name Plateosaurus

Back in the 1990s, I compiled a list of dinosaur names with
etymologies that I had researched from the original sources wherever
possible. The late vertebrate paleontologist Donald Baird was a great
help in this project, and offered critical comments and photocopies of
rare works. I wrote a number of articles on the topic for the Dinosaur
Report newsletter for the Dinosaur Society. One article in 1995 was
about the German paleontologist Hermann von Meyer, entitled “Pondering
the Pachypoda.” In the article, I gave the etymology “broad lizard”
for Plateosaurus, with the spelling explained by the genitive-case
form plateos of Greek platys “broad.” I later posted this etymology on
Jeff Poling’s website Dinosauria.com. That website is sadly gone, but
my old lists of names are still posted on some mirror sites:
http://web.me.com/dinoruss/dml/names/dinop.htm

Currently, the English language Wikipedia article for Plateosaurus
states the following:
