Two New Dinosaurs



Hi All -

   These just out:

You, H., Q. Ji, and D. Li. 2005. _Lanzhousaurus magnidens_ gn. et sp. nov.
from Gansu Province, China: the largest-toothed herbivorous dinosaur in the
world. Geological Bulletin of China 24:785-794.

   I've had the good fortune to see this thing up close and personal, and
it is imPRESSive, as far as ornithopods go.  Each tooth is more than half
the size of my hand!

You, H., D. Li, Q. Ji, M. C. Lamanna, and P. Dodson. 2005. On a new genus of
basal neoceratopsian dinosaur from the Early Cretaceous of Gansu Province,
China. Acta Geologica Sinica (English Edition) 79:593-597.

ABSTRACT:  A new genus and species of basal neoceratopsian dinosaur,
_Auroraceratops rugosus_, is reported based on material from the Early
Cretaceous Xinminpu Group in the Gongpoquan Basin of Gansu Province, China.
_Auroraceratops_ is represented by a nearly complete skull and low jaws, and
different greatly from all other neoceratopsians by its considerable breadth
of the nasals, fungiform expansion of the dorsal end of the lacrimal, highly
developed rugosity of the jugal, dentary and surangular, and inflated,
striated premaxillary teeth. The finding of _Auroraceratops_ adds diversity
and helps elucidate the evolution of basal neoceratopsian dinosaurs.

   Another in the line of small, almost 100% frill-free, insufferably cute
little early neoceratopsians. Bigger than _Archaeoceratops_, though.  Skull
almost turtle-like in lateral view.
