Dinosaur Genera List corrections #148

[Dinogeorge@aol.com]

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 
transmission errors]:

"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 
above.

[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 
yet unpublished.

[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
ocephale brevis.

[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 
newspaper
        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 
through it.

e-mailing me directly or by downloading from the Dinosauricon website.
