Arundel dig possibility (more details)
Hi again gang,
First off, this is a brief general message to allay concerns regarding the
location of my site. I kind of took it for granted that most list members
know me from my Arundel posts and thus knew what part of the universe I was
talking about. I also want to thank Allan Edels for his accurate assessment
of the situation.
The Arundel Clay is the middle member of a tripartite divided Potomac
Group(?) which only occurs in Maryland and mostly between Baltimore Md. and
Washington DC. North and south of this the Arundel is not preserved resulting
in what stratigraphers outside of Md refer to as Potomac Undiff. (in Va to
the SW and in De., NJ to the NE)
This is one of the salient reasons why the fauna of this terrestrial unit are
so unique and it occurs no where else in eastern N. America! The closest
contemporaneous fauna occur in the Clovery, Cedar Mt., Trinity, and Antlers
Fms of the Weestern Interior.
Hope this clears up the "confusion"
I also have gotten a surprising amount of replies, so much that I cannot
possibly answer them now on my shortened lunch break. I will however, reply
en masse later this evening as I have two classes to attend after work. This
will give more time to pick up a few more late enquireys.
