RE: Weird mammal cladograms, and dino implications
On related subject of Cretaceous bigogeography (mammal-inspired), the
following will be of interest to many:
Rich, T.H., Vickers-Rich, P., Constantine, A., Flannery, T.F., Kool, L. &
van Klaveren, N. 1999. Early Cretaceous mammals from Flat Rocks, Victoria,
Australia. Records of the Queen Victoria Museum, Launceston, 106: 1-35.
The authors examine in detail the controversial tribosphenic mammal
Ausktribosphenos, and they describe a new eupantothere - Teinolophos - from
the Early Cretaceous (Aptian) of Victoria, Australia. They also explore
some interesting palaleobiogeographic hypotheses - thought-provoking stuff,
and certainly relevant to Cretaceous dinosaur distributions.
One admirable feature is the inclusion (reprinting) of papers previously
published in Lethaia - both pro and con the interpretation of
Ausktribsphenos as a placental mammal.
Wish I had time to sit down and read it thoroughly.
