100 MA North America

[john-schneiderman@cox.net]

I am looking for paleogeographic map[s] or reference articles of North 
America as it looked 100 MA [late Albain-early Cenomanian]. Especially 
interested in the position of the coast-line along the western margins 
of Appalachia [eastern North America]. Any references to noted features 
such as paleo-river channels, deltas, offshore barrier islands, near 
shore topographic highs/cliffs, tidal flats/brackish estuaries, etc.

At this time in North America's paleo-history the epicontinental seaway 
was entering its transgressive phase [Muddy-Mowry Sea; late Albian --> 
Greenhorn Seaway; early Cenomanian] and the connection of western and 
eastern North America was lost. Appalachia and its dinosaur-fauna would 
be isolated for at least until the earliest Maastrichtian.
