Largest Mesozoic Mammal



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...
