Pappotherium

Pappotherium is an extinct genus of mammals from the Albian (early Cretaceous) of Texas (USA), known from a fossilized maxilla fragment bearing two tribosphenic molars, discovered within the Glen Rose Formation near Decatur, Wise County, Texas.

Slaughter argued that Pappotherium should have been a basal form close to the metatherian-eutherian divergence point; this mammal likely was an arboreal insectivore.
