Here's some new stuff I found at the
library.
Chiappe, Kellner, Rivarola, Davila and Fox, 2000.
Cranial morphology of Pterodaustro guinazui (Pterosauria: Pterodactyloidea) from
the Lower Cretaceous of Argentina. Contributions in Science (Natural History
Museum of Los Angeles County) 483 1-19.
Describes the skull and relationships of
Pterodaustro. Weird spatulate maxillary teeth with ossicles on the
palate. It's most closely related to Ctenochasma.
Sankey, 2001. Late Campanian southern dinosaurs,
Aguja Formation, Big Bend, Texas. Journal of Paleontology 75(1)
208-215.
This one's already been mentioned, but here's a bit
more detail. The only dinosaur remains consist of teeth and tooth
fragments of the following groups- Tyrannosauridae, Ricardoestesia gilmorei,
Ricardoestesia isosceles, Theropoda gen. et. fam. indet. (see below),
Hadrosauridae, Pachycephalosauria, Ceratopsidae.
Theropoda indet.
Late Campanian, Late Cretaceous
Aguja Formation, Texas, US
Material- (LSUMG 488:5483) tooth (FABL 9
mm)
(LSUMG 489:6239) tooth (FABL 5.5 mm)
Description- These tooth fragments are not
assignable to any known genus of Judithian theropod. They are slightly
flattened, recurved and serrated (3.5-5.5 per mm). The serrations are
slightly rounded with narrow interdenticle spaces.
Relationships- Sankey finds these teeth are very
similar to Dromaeosaurus, except they lack the lingually twisted anterior
carinae autapomorphic of that genus (and seen in cf. Dromaeosaurus teeth from
the Kimmeridgian of Portugal). Perhaps this is a distinct dromaeosaurine
genus.
Rauhut, 1999. A dinosaur fauna from the Late
Cretaceous (Cenomanian) of Northern Sudan. Palaeontologia Africana 35
61-84.
Can you say African therizinosauroids,
oviraptorosaurs and dromaeosaurines or troodontids.....
More tomorrow. :-)
