Dinosaur Genera List corrections #127

[Dinogeorge@aol.com]

Thanks to Tracy Ford, I've come across another Stephan Pickering private 
publication, this one going back to 1995; Tracy can confirm the year, since 
that was when he received it:

Pickering, S., 1995. "Jurassic Park: Unauthorized Jewish Fractals in 
Philopatry," A Fractal Scaling in Dinosaurology Project, 2nd revised 
printing, Capitola, California: 478 pp. [January 27, 1995].

This pushes back the dates of some of the Pickering nomina nuda in the 
previous Dinosaur Genera List corrections, and it adds two new published 
genera to the list. The book itself is a virtually exhaustive illustrated 
bibliography and filmography of the motion picture Jurassic Park, and it 
includes citations to numerous scientific dinosaur papers as well as, 
strangely enough, articles and other literature dealing with the Nazi 
Holocaust. It is difficult for me to see a common thread here, except perhaps 
that Steven Spielberg produced both Jurassic Park and Schindler's List motion 
pictures.

Here are the new genera and species in the book and corrected citations to 
genera and species mentioned in Dinosaur Genera List corrections #126. All 
are nomina nuda as far as Tracy and I know. Citations of dates before 1995 
are probably to unpublished manuscripts:

Altispinax lydekkeri-huenensis Pickering, 1984 vide Pickering, 1995
Altispinax lydekkerhueneorum Pickering, 1994 vide Pickering, 1995 (correction 
to spelling of preceding)
Centrosaurus albertensis (Lambe, 1913) Pickering, 1995 n. comb. for Styracosau
rus albertensis
Ceratosaurus willisobrienorum Welles, H. P. Powell & Pickering vide 
Pickering, 1995
Elaphrosaurus philtippettorum Pickering, 1995
Liassaurus huenei Welles, H. P. Powell & Pickering vide Pickering, 1995
Megalosaurus phillipsi Welles, H. P. Powell & Pickering vide Pickering, 1995
Merosaurus newmani Welles, H. P. Powell & Pickering vide Pickering, 1995
Metriacanthosaurus brevis Welles, H. P. Powell & Pickering vide Pickering, 
1995
Metriacanthosaurus reynoldsi Welles, H. P. Powell & Pickering vide Pickering, 
1995
Walkersaurus Welles, H. P. Powell & Pickering vide Pickering, 1995 (this 
corrects the DGL entry for this genus)

Pickering also credits Maleevosaurus to himself in 1984, whereas Carpenter 
published the name in 1992 (for the same species). The 1984 date must, 
however, refer to a manuscript or some other unpublished document and cannot 
be considered as having priority. And there is also a photo of the Dilophosaur
us breedorum type skull, captioned with its name: a 1995 nomen nudum of the 
species described in 1999.

The two new genera (#872 and 873, respectively) are:

Liassaurus Welles, H. P. Powell & Pickering vide Pickering, 1995 [nomen nudum]
Merosaurus Welles, H. P. Powell & Pickering vide Pickering, 1995 [nomen nudum]

The former is not familiar to me but is probably the name of a Liassic 
theropod from Europe mentioned in the Welles & H. P. Powell theropod 
manuscript; the latter is, I believe, the new name for the large theropod 
whose knee joint is the original type specimen of Scelidosaurus harrisonii. 
The Elaphrosaurus and Ceratosaurus species belong to the North American 
dinosaur list; Maleevosaurus Pickering, 1984 vide Pickering, 1995 may be 
added as a nomen nudum synonym of Maleevosaurus Carpenter, 1992; the other 
species may all be added/corrected in appropriate places to the list of 
European dinosaurs (all but Liassaurus are surely British; Liassaurus may be 
British or continental European).
