Dinosaur Genera List update #192
Feathered Dinosaurs and the Origin of Flight, S. J. Czerkas, ed., The
Dinosaur Museum Journal 1: vi + 136 pp.
This new book from the Dinosaur Museum in Blanding, Utah, is out, and it
contains four new genera that have been added to the Dinosaur Genera List,
becoming #953-956:
Archaeovolans Czerkas & Xu, 2002* [bird, originally part of Archaeoraptor
specimen; PSS -> Yanornis]
Cryptovolans Czerkas, Zhang, J. Li & Y. Li, 2002
Omnivoropteryx Czerkas & Ji Q., 2002
Scansoriopteryx Czerkas & Yuan, 2002
Two new pterosaurs are described in the book as well: Utahdactylus kateae and
Pterorhynchus wellnhoferi.
I have also begun another >Dinosaur Project< that I'm calling The Dinosaur
Catalogue. If I ever finish it (and right now I'm enthusiastically putting
lots of time into it, so I probably will, but I still have about 900 entries
to compile), I'll see about having it published somewhere. Here are the
present Dinosaur Catalogue entries for these four new genera. I hope the
notations are easy to understand; unfortunately, a lot of information is also
encoded in the typography (centering, boldface, small caps, type size,
special characters) and some of this will be lost in email transmission. When
the Catalogue is complete, every named dinosaur species, whether synonym or
not, will have its own entry, similar to these. (Renamings will, however, be
simple references to the presently accepted names of the species.) I
published form I hope to have each major entry accompanied by a Tracy Ford
picture of the hypodigm APK.
APK notation for hypodigm: "approximate percent known." APK:a/b compactly
denotes that about a% of the skull anatomy is known for this species, and b%
of the postcranial anatomy. Thanks to wife Andrea for helping me to boil this
concept down to just a couple of letters and numbers a few evenings ago.
Archaeovolans Czerkas & Xu, 2002
Possible junior subjective synonym of Yanornis (Czerkas & Xu, 2002)
Nondinosaurian: Bird
Archaeovolans repatriatus Czerkas & Xu, 2002â*
Possible junior subjective synonym of Yanornis martini (Czerkas & Xu,
2002)
Lower Cretaceous > Jiufotang Fm.
Asia > China > Liaoning Prov. > Chaoyang Cty. > Xiasanjiazi(?)
IVPP V12444: A nearly complete semiarticulated skeleton, missing the tail
and parts of the pelvis and hindlimbs, in slab and counterslab
Hypodigm APK:90/80: Holotype specimen only; the feet and lower hindlimbs
may not belong with the other parts of the specimen (Czerkas & Xu, 2002)
Listed here because the holotype specimen was once part of the composite
specimen called Archaeoraptor liaoningensis, a dromaeosaurid theropod (cf.)
Cryptovolans Czerkas, Zhang, J. Li & Y. Li, 2002
Crytovolans Czerkas, Zhang, J. Li & Y. Li, 2002: Misspelling
Theropoda > Tetanurae > Coelurosauria > Maniraptora > Deinonychosauria >
Dromaeosauridae
Cryptovolans pauli Czerkas, Zhang, J. Li & Y. Li, 2002â
Lower Cretaceous > Upper Jiufotang Fm.
Asia > China > Liaoning Prov. > Chaoyang City > Shangheshou
LPM 0200/0201: Slab and counterslab of a crushed virtually complete
skeleton with feather impressions, missing parts of a pes and a manus
Hypodigm APK:100/99: LPM 0159 headless postcranial skeleton in slab,
missing cervicals and caudals, with feather impressions; and scattered bones
in holotype specimen of Omnivoropteryx sinousaorum; in addition to holotype
skeleton
Omnivoropteryx Czerkas & Ji Q., 2002
Theropoda > Tetanurae > Coelurosauria > Maniraptora > Oviraptorosauria >
Omnivoropterygidae
Omnivoropteryx sinousaorum Czerkas & Ji Q., 2002â
Lower Cretaceous > Upper Jiufotang Fm.
Asia > China > Liaoning Prov. > Chaoyang City > Shangheshou
CAGS02-IG-gausa-3/DM 609: Nearly complete skeleton in matrix, missing
portions of cervicals, coracoids, sternum, portions of scapula, and distal
portions of one wing; slab also includes scattered bones tentatively referred
to Cryptovolans
Hypodigm APK:100/90: Holotype skeleton only
Described as a primitive bird in its own order Omnivoropterygiformes,
this genus seems closely related to Caudipteryx and is here tentatively
classified as a volant oviraptorosaurian
Scansoriopteryx Czerkas & Yuan, 2002
Theropoda > Tetanurae > Coelurosauria > Maniraptora > Scansoriopterygidae
Scansoriopteryx heilmanni Czerkas & Yuan, 2002â
Early Cretaceous > Jehol Grp. > Yixian Fm.
Asia > China > Liaoning Prov. > Lingyuan City > Dawangzhanzi
CAGS02-IG-gausa-1/DM 607: Partial skeleton including posterior half of
skull and lower jaws, forelimb elements, partial pelvic girdle and hindlimb
elements, and feather impressions
Hypodigm APK:50/50: Holotype skeleton only
Additions and corrections to the above entries would be most appreciated.
Please note that I want to keep things as compact as possible (although, of
course, sometimes compactness is just not possible).
