Largest Mesozoic Mammal

["Jerry D. Harris" <dinogami@hotmail.com>]

Hi All -

  Another one from a past issue of _Chinese Science Bulletin_:

Li, J., Wang, Y., Wang, Y., & Li, C. 2001. A new family of primitive mammal 
from the Mesozoic of western Liaoning, China. Chinese Science Bulletin 
46(9): 782-785.

Abstract A fairly well-preserved specimen of a new primitive mammal, 
_Repenomamus robustus_ gen. et sp. nov., has been described from the Yixian 
Formation (Lower Cretaceous), western Liaoning, China. This animal has 
several derived characteristics, such as well-developed dentary/squamosal 
articulation, reduced number of tooth, differentiation of premolars and 
molars in postcanine teeth, presence of a dorsal process of the premaxilla 
that is not in contact with the nasal, closed medial wall of the orbit, and 
presence of fingerlike promontorium on the petrosal. It also retains some 
primitive reptile-like features. It is the most primitive taxon among the 
three mammals known from the Jehol Biota, and also represents the largest 
mammal of Mesozoic age over the world.

  As with the last one, the PDF link doesn't seem to work.  I have also 
been unable to fully view the PDF of the _Longipteryx_ paper in Chinese -- 
Acrobat reports a CMap error (corrupt or missing font file), and the first 
page doesn't come up at all.  Anyone have a clue about this one?  I've 
installed Adobe's Chinese fonts...
