The Dinosauria 2nd Ed. - New and Excluded Theropoda
There is a LOT of information in this book the DML should know about.
First, there are three new theropod taxa, which seem to be the only new taxa
in the volume.
Megalosaurus? "cachuensis" Weishampel, Barrett, Coria, Le Loeuff, Xu, Zhao,
Sahni, Gomani and Noto, 2004
Dapuka Group, Xinjiang, China
Comments- This is only present as a name in the Dinosaur Distribution
chapter, so is a nomen nudum. It may be the same as the nomen nudum
Megalosaurus? "dapukensis" Zhao 1985, which is not in the book.
"Aniksosaurus" Martinez vide anonymous, 1997
"A. darwini" Weishampel, Barrett, Coria, Le Loeuff, Xu, Zhao, Sahni, Gomani
and Noto, 2004
Cenomanian-Coniacian, Late Cretaceous
Bajo Barreal Formation, Argentina
Comments- The name "Aniksosaurus darwini" has been on the internet since
2001, but this is its first publication in print. It is merely a name in
the Dinosaur Distribution chapter though, so is still a nomen nudum.
Rinchenia Osmolska, Currie and Barsbold, 2004
R. mongoliensis (Barsbold, 1986) Osmolska, Currie and Barsbold, 2004
= Oviraptor mongoliensis Barsbold 1986
Early Maastrichtian, Late Cretaceous
Nemegt Formation, Mongolia
Comments. Osmolska et al. attribute this name to Barsbold 1997, but the
latter use was as a nomen nudum. I don't see anything that would bar
Osmolska et al. from having the name attributed to them for this chapter
though. It's diagnosed, illustrated, and Barsbold 1986 and Oviraptor
mongoliensis are explicitly stated as being the species and reference it's
Now, what theropods (and basal saurischians) aren't included in The
Dinosauria? Well, most nomina nuda aren't, but there are exceptions. The
following nomina nuda are in the book, though italicized and not surrounded
by quotation marks-
Szechuanosaurus "yandonensis" (Basal Tetanurae)
Tyrannosaurus "lanpingensis" (Tyrannosauroidea)
"Paleopteryx thomsoni" (Dromaeosauridae)
"Holbotia ponomarenkoi" (Basal Avialae)
The four marked by asterisks are only in the Dinosaur Distribution chapter.
Moving to valid taxa, the following are only mentioned in the text, not in
an informational table.
Dilophosaurus? sinensis (Ceratosauria)
Longipteryx (Basal Avialae)
Shuvosaurus is considered non-dinosaurian (though Rauhut's 1997 opinion is
mentioned; his 2000/2003 one is not), and the other two also have Dinosaur
Distribution entries. Longipteryx is only mentioned in the context of having
feathers, but there are a few sentences about D? sinensis.
Calamosaurus is never mentioned, as it is called Calamospondylus foxi in the
Basal Tetanurae table.
The Ceratosauria table fails to differentiate Longosaurus from Coelophysis?
longicollis, though they have different holotypes.
The following are present as their original species, but their new genera
are not listed-
Spinostropheus (as Elaphrosaurus gautieri) (Ornithomimosauria) 2004
Explorornis (as Enantiornis walkeri) (Basal Avialae) 1998
Incolornis (as Enantiornis martini) (Basal Avialae) 1998
Guildavis (as Ichthyornis tener) (Basal Avialae) 2004
There are many taxa which have Dinosaur Distribution entries, but are
otherwise not listed. Publication dates are listed below if they are
"Cathayornis" caudatus 1997
Hesperornis rossicus 1993
Some of these were probably too new, and others seem to lack a proper
chapter (possible Dinosauria). A few are poorly known, but I can't help but
think someone goofed in not including Compsosuchus, and that Padian could
have done a better job on the Basal Avialae chapter (Eocathayornis,
Halimornis, Sapeornis and Epidendrosaurus are included, all from 2002).
Strangely, Confuciusornis chuonzhous and C. suniae are included, but not the
enantiornithine taxa from that same volume.
In general, neornithines aren't treated by the book. The only one listed in
a table is "Graculavus" lentus (which is now Austinornis). However, about
half the known Mesozoic neornithines have Dinosaur Distribution entries. I
can't figure out the reason some don't, since some of the best known taxa
(e.g. Cimolopteryx, Graculavus) are missing. In any case, the following are
absent from the book-
Finally, the following taxa are not found anywhere in the book at all.
Again, recent taxa have publication dates listed.
Tyrannosaurus? zhuchengensis 2002
Jinzhouornis yixianensis 2002
Jinzhouornis zhangjiyingia 2002
"Cathayornis" aberransis 2002
Explorornis? walkeri 1998
Hesperornis bairdi 2002
Hesperornis chowi 2002
Hesperornis macdonaldi 2002
Hesperornis mengeli 2002
Again, Picrodon and Asiamericana might be deemed possibly dinosaurian, while
Suchosaurus and "Ornithoscheirus" hilsensis are poorly known. It's odd for
Microraptor gui to be included, but not the earlier named Cryptovolans.
Yandangornis and Panteleev's Soviet bird paper seem to have slipped by
Overall, I'm impressed with the number of recently described taxa in the
book, especially with Weishampel et al.'s job in the Dinosaur Distributions
