JVP 27(1)



For those of you awaiting your spiffy new JVP issue, here's a quick look
at what you have to look forward to in terms of dinosaurs (and
pterosaurs):

Ezcurra, Martín D, and Cuny, Gilles. 2007. The coelophysoid
Lophostropheus airelensis, gen. nov.: a review of the systematics of
"Liliensternus" airelensis from the Triassic-Jurassic boundary outcrops
of Normandy (France). 73-86.

Liliensternus airelensis gets a new name, and is found to be closer to
the coelophysids ("Syntarsus" kayentakatae + Coelophysis) than to
Liliensternus liliensterni.  All material pertaining to it is
redescribed.  The paucity of Rhaetian dinosaurs is discussed as well. 
For those of you keeping score on these things, Syntarsus rhodesiensis is
included in Coelophysis, and Ceratosauria is closer to Tetanurae
(Ceratosauria + Tetanurae = Averostra).


Averianov, Alexander O., and Dieter-Sues, Hans. 2007. A new troodontid
(Dinosauria: Theropoda) from the Cenomanian of Uzbekistan, with a review
of troodontid records from the territories of the former Soviet Union.
87-98.

Say hello to Urbacodon itemirensis, based on ZIN PH 944/16, a left
dentary from the Cenomanian Dzharakuduk Formation.  It's one of those
troodontids with unserrated teeth (32 of them in the type dentary), and
the jaw is rather straight in dorsal/ventral view, with a diastema toward
the back of the tooth row.  Many troodontid bits from across Central Asia
are discussed.  Troodon asiamericanus is dubious, and T. isfarensis may
be based on a hadrosaur prefrontal, not a troodont frontal (although the
bone could not be located).  Additionally, Archaeornithoides is
tentatively retained as a separate genus, although it could prove to be a
juvenile Byronosaurus, which also has unserrated teeth.


Therrien, Francois, and Henderson, Donald M. 2007. My theropod is bigger
than yours...or not: estimating body size from skull length in theropods.
108-115.

Here's an early contender for the best title of the year.  Two
regressions show that skulls get longer relative to body length with
increasing size, and that body mass increases faster than skull length
with increasing body size.  These regressions indicate much heavier
carcharodontosaurids than previously suggested (in rex's weight class),
and shorter and much heavier spinosaurids than suggested (past rex).


Short Communications
García, Rodolfo A. 2007. An 'egg-tooth'?like structure in titanosaurian
sauropod embryos. 247-252.

The title tells the story.  At least six embryonic titanosaurs from Auca
Mahuevo had a little bony lump on the premaxilla that is not seen in the
adults.


Butler, Richard J., and Upchurch, Paul. 2007. Highly incomplete taxa and
the phylogenetic relationships of the theropod dinosaur Juravenator
starki. 253-256.

A priori removal of seven taxa in the original description's tree
(Göhlich and Chiappe, 2006) was unjustified, and their results thus do
not support Juravenator as a compsognathid, but they do support a basal
maniraptoran position.


Bennett, S. Christopher. 2007. Reassessment of Utahdactylus from the
Jurassic Morrison Formation of Utah. 257-260.

The specimen is found to be undiagnostic, with misidentifications of
remains, and there is no evidence that it was a pterosaur. He considers
it to be an indeterminate diapsid.
