JVP 19:1

The latest Journal of Vertebrate Paleontology is packed full of goodies,
only some of which are mentioned here.  Out of 17 items in the table of
contents (other than the guidlines for preparation), six are explicitly
about non-avian dinosaurs, one on a Mesozoic bird, one on DNA in paleo
studies (with reference to dinos), one on a new aetosaur, two on
ichthyosaurs, and one on lepidosaurs from the Lower Cretaceous Kirkwood Fm
of South Africa.  In contrast, there are only three research articles on
mammals (one of which, though, is David Froehlich's long awaited study of
basal perissodactyls), a short taxonomic note on mammal definitions and
relationships, and a book review on McKenna and Bell's Classification of
Mammals Above the Species Level.  Good to see the appropriate emphasis of
sauropsid to synapsid papers... (and no fish).

The archosaurian papers are:

Ji Q., L.M. Chiappe & Ji S.  1999.  A new late Mesozoic confuciusornithid
bird from China.  JVP 19:1-7.  [names and describes _Changchengornis
hengdaoziensis_, the "cover girl" of the issue]

Kelman, L.M. & Z. Kelman.  1999.  The use of ancient DNA in paleontological
studies.  JVP 19:8-20.

Heckert, A.B. & S.G. Lucas.  1999.  A new aetosaur (Reptilia: Archosauria)
from the Upper Triassic of Texas and the phylogeny of aetosaurs.  JVP
19:50-68.  [names and describes _Coahomasuchus kahleorum_, a small aetosaur
demonstrating the presence of aromr down the limbs and on the ventral surface]

Padian, K., J.R. Hutchinson & T.R. Holtz, Jr.  1999.  Phylogenetic
definitions and nomenclature of the major taxonomic categories of the
carnivorous Dinosauria (Theropoda).  JVP 19:69-80.  [already discussed on
the list]

Sullivan, R.M. & S.G. Lucas.  1999.  _Eucoelophysis baldwini_, a new
theropod dinosaur from the Upper Triassic of New Mexico, and the status of
the original types of _Coelophysis_.  [a new taxon, or a variant of an old
one?  Time will tell.  Some comments concerning pubic fenestration among
coelophysoids may require updating.]

Varricchio, D.J., F. Jackson & C.N. Trueman.  1999.  A nesting trace with
eggs for the Cretaceous theropod dinosaur _Troodon formosus_.  JVP
19:91-100.  [More details on troodontid nesting habits, following Varricchio
et al.'s 1997 paper in Nature 385:247-250.]

Frankfurt, N.G. & L.M. Chiappe.  1999.  A possible oviraptorosaur from the
Late Cretaceou of northwestern Argentina.  JVP 19:101-105.  [A single
cervical, which does look very oviraptorosaurian. NO, it is not named; *NO*,
I don't expect they plan on naming it!!  Maybe if they find more...  Also,
*NO*, Frankfurt & Chiappe do not regard Figure 3 as a cladogram of theropod
relationships, beyond the immediate relationships between the El Brete
specimen, oviraptorids, _Chirostenotes_, therizinosauroids, and
(interestingly) the Como Bluff Quarry 9 cervical described by Makovicky in
the 1997 JVP.)

Upchurch, P.  1999.  The phylogenetic relationships of the Nemegtosauridae
(Saurischia, Sauropoda).  JVP 19:106-125.  [Updates Upchurch's 1998
phylogeny in response to Salgado et al.'s 1997 papers in Ameghiniana.
Unfortunately, does not include new data from Wilson & Sereno's 1998 study.
Retains Nemegtosauridae in Diplodocoidea, provisionally places
_Antarctosaurus wichmannianus_ as the sister taxon to Nemegtosauridae, but
presents evidence to suggest the South American form is an amalgam of
different sauropod taxa.]

Sullivan, R.M.  1999.  _Nodocephalosaurus kirtlandensis_, gen. et sp. nov.,
a new ankylosaurid dinosaur (Ornithischia: Ankylosauria) from the Upper
Kirtland Formation (upper Campanian), San Juan Basin, New Mexico.  JVP
19:126-139.  [A new knobby-headed ankylosaurid, provisionally considered
part of a dichotomy with the Asian taxa _Saichania_ and _Tarchia_, but not
subjected to an actual numerical phylogenetic analysis (just a "insert taxon
where it makes the most sense to me" approach at present.]

(Oh, and a nit-pick: despite the use of the term in the above paper, there
is no such thing as a "crown group ankylosaurid".  Ankylosauridae is
extinct: ergo, there is no crown group.)

(For fairness sake, nit-pickers can find a monstrously horrible taxon name
that must have squeaked by me during earlier drafts of the Padian et al.
paper, on column 1 of page 78...  D'oh!!  D'oh!!!  D'OHH!!!!)

Oh, and in Lucas (third time an issue's a charm...) & Emry's entelodont
paper, I found out that _Dinohyus_ (longtime favorite for ugliest Tertiary
mammal) is properly called _Daeodon_.
