Dinosaur Genera List corrections #148
Andy Heckert recently informed a number of paleontology lists of the
publication of the new volume Dinosaurs of New Mexico, Bulletin #17 of the
New Mexico Museum of Natural History and Science [edited for typography and
"We are pleased to announce that New Mexico Museum of Natural History and
Science Bulletin 17, Dinosaurs of New Mexico, is now available. This 230-page
volume, edited by Spencer G. Lucas and Andrew B. Heckert, contains 27 papers
derived from the highly successful symposium of the same name held Saturday,
April 29 in Albuquerque. Topics covered include dinosaur body and trace
fossils from each period of the Mesozoic and even putative Paleocene
dinosaurs. A full table of contents appears later in this message. This
bulletin was published with support from the U.S. Bureau of Land Management.
"Volumes can be purchased directly from the museum Natureworks Store (see the
NMMNH web page at: www.museums.state.nm.us/) Each volume is $30, with an
additional $5 shipping and handling for domestic orders, $10 overseas.

Needless to say, the volume is intensely interesting and a "must have" for
any dinosaur library, a most valuable contribution to dinosaurology. It also
includes a number of taxonomic changes, which I'll outline here. The articles
containing the changes are referred to by number from the Table of Contents
[A] Article 9 synonymizes the genus Seismosaurus with Diplodocus and uses the
new combination Diplodocus hallorum for the species originally named Seismosau
rus hallorum. This combination also appears in articles 11 and 12. The basis
for the reassignment is revealed in article 9 to be a personal communication
from Brian Curtice; an actual anatomical comparison of the two genera is as
[B] Tracy Ford's article 23 describes the stegopeltine ankylosaurid Glyptodont
opelta mimus gen. et sp. nov. and the edmontoniine nodosaurid Edmontonia
australis sp. nov. and reviews/reclassifies almost all the ankylosaurs
according to their osteoderm morphology.
[C] Robert Sullivan's article 24 redescribes two species of Stegoceras as
species of the Asiatic genus Prenocephale: Prenocephale edmontonensis and Pren
[D] Thomas Williamson's article 25 synonymizes the hadrosaurid species Anasazi
saurus horneri and Naashoibitosaurus ostromi with Kritosaurus navajovius,
attributing the differences among them as due to individual variation and
ontogeny. Kritosaurus remains separate from Gryposaurus, however. The article
thus supports Horner's 1992 work versus Hunt and Lucas's 1993 work, and
removes Kritosaurus from nomen dubium status. Somehow, I don't think this
will be the last word in this debate...
Anyway, I accordingly add genus #892 to the Dinosaur Genera List:
Glyptodontopelta Ford, 2000
and to the table of North American dinosaur species I add these two:
Edmontonia australis Ford, 2000
Glyptodontopelta Ford, 2000
G. mimus Ford, 2000â
The genus Prenocephale is added to the list of North American dinosaur
genera, its entry reading as follows:
Prenocephale Maryanska & OsmÃlska, 1974
?P. brevis (Lambe, 1918) Sullivan, 2000
= Stegoceras breve Lambe, 1918 emend. Sues & Galton, 1987
= Stegoceras brevis Lambe, 1918Â
= Troodon brevis (Lambe, 1918) Gilmore, 1924
= TroÃdon brevis (Lambe, 1918) Gilmore, 1924Â
?P. edmontonensis (Brown & Schlaikjer, 1943) Sullivan, 2000
= Stegoceras edmontonense (Brown & Schlaikjer, 1943) Kuhn, 1964 emend.
Sues & Galton, 1987
= Stegoceras edmontonensis (Brown & Schlaikjer, 1943) Kuhn, 1964Â
= Troodon edmontonensis Brown & Schlaikjer, 1943
= TroÃdon edmontonensis Brown & Schlaikjer, 1943Â
NOTE: These species may on further study be shown to belong to new genera
distinct from the Asiatic genus Prenocephale.
The two species of Prenocephale and all notations about them are removed from
the genus Stegoceras, of course.
The entry for Seismosaurus now reads as follows:
Seismosaurus Gillette, 1991
= "Seismosaurus" Gillette, 1986 [nomen nudum; name published in numerous
accounts in 1986 and in an article by I. Anderson in New Scientist,
April 23, 1987: 24]
S. hallorum Gillette, 1991 emend. Olshevsky, 1991â
= Seismosaurus halli Gillette, 1991âÂ
= Diplodocus hallorum (Gillette, 1991) Lucas & Heckert, 2000
I'm not quite as ready to synonymize Seismosaurus with Diplodocus as Lucas &
Heckert (and Brian Curtice) are. Also, I'm not touching Kritosaurus, Anasazisa
urus, and Naashoibitosaurus for a while, either, although I will note as
potential the synonymy advocated in Williamson's article.
Alex Downs in article 7 suggests Camposaurus is a junior synonym of Coelophysi
s. A note will appear to this effect with the listing for Camposaurus.
All these changes will appear in the forthcoming second printing of Mesozoic
Meanderings #3, once the first printing sells out (still have about 60 copies
in stock). I will probably find more taxonomic items in the volume as I go
