I just got back from WAVP in Mesa, and thought I'd share with everyone what
went on, and the talks/posters/abstracts that are related to dinosaur
science (note: I missed the first round of talks, so if any of the list
members that were there caught Brian Curtice's talk, they could comments on
it. I cannot).
The talk that caught my attention the most was the talk by Heckert on
Heckert et. al correlating the lowest Chinle (around St. Johns) to the
Ishigualasto Formation. They base this mostly on a partial (partial is key)
skull of _Saurosuchus_. This means, according to them, that the dinosaurs in
the lower Chinle (and there are some) are equally as old as the dinosaurs in
the Valley of the Moon. Interesting.
Also on the first day, there was a talk by Doug Wolfe on, "Science, Media,
and the true story of the discovery of _Zuniceratops chrisopheri_" which was
quite interesting, and dealt with not only the media's take on it, but what
science was actually being done and what was being learned.
Also that day, our very own HP Tracy Ford gave a talk on the occurance of
"Aublysodon" teeth from Mexico, "the southernmost record of tyrannosaurid
theropods". It was a very interesting talk with some neat overheads, showing
the different teeth. He also mentioned that if _Labocania_ is an abelisaur,
then tyrannosaurids and abelisaurids were sharing the same environment,
which I found very interesting.
Not quite dinosaur related, but Mesozoic and reptilian, so I'll mention it.
Barry Albright talked about two new plesiosaurs from southern Utah, which
was also a cool talk.
The poster session was that night, and beyond my own humble poster, Jim
Kirkland had a poster on a trackway in St. George, Utah; Rose Difley had a
poster on a dinosaur nesting site in the North Horn of central Utah; John
Foster presented some data on the relative abundance of different sauropod
genera in the late Jurassic; Andrew Heckert presented two posters, one by
Lucas and Heckert on age correlation of Cretaceous vertebrates from
southeastern Arizona, and one by Rinehard, Heckert and Lucas on a new
crocodylomorph from the Najavo Sandstone. Also present was a very slick
poster by Wolfe, Beekman, McGuiness and Thomas Robaria on the _Zuniceratops_
bonebed, and a poster by Sterling Nesbitt on some middle Triassic reptiles
from the Moenkopi Formation, including a possible partial herrerasaur distal
pubis (I don't know if I buy that, but it was very interesting, and would be
neat if it was!). If it was dinosaurian, coupled with Heckert's talk, that
would indicate that the oldest known dinosaurs come from the American
southwest, as opposed to South America.
Then today (Sunday), there was a very intersting talk on mammalian evolution
and diversity at the K-T boundary by William Clemens, a discussion of
dinosaur material from the Fort Crittenden Formation by Bob McCord, from
McCord et al. There was also a very interesting talk on the forlimbs of
_Apatosaurus_ by Philip Platt, that suggested that sauropods (or at least,
_Apatosaurus_) walked with a semi-sprawling front limb posture. Jim Kirkland
gave a neat talk on the environment of the Morrison Formation. We then all
migrated over to the Mesa Southwest Museum collections, and poked around in
there for a bit. That's all she wrote folks (unless I forgot something,
which I'm sure the other list members will correct.) I finally got myself a
copy of PDW, so that was good. It was good to actually meet some other
DMListers, to put faces to names. I think a good time was had by all, and
that's the end of my schpiel.
