cowsharks Posted January 26, 2015 Share Posted January 26, 2015 I'm looking for a description of the various layers, also sometimes referred to as "zones" (aka Shattuck Zones), along Calvert Cliffs in Maryland. From what I understand, the actual fossil layers (members/formations) don't necessarily correspond one for one to the Shattuck zones. One time I saw a diagram that depicted the layers and where they were located within the cliffs; this diagram showed the cliffs all the way from Chesapeake Beach down to Solomons. I can't seem to find it though. It would be great though to find a description of how to identify each zone and/or fossil formation. For example, I've always understood zone 10 to be a layer that is gray in color, full of sand and shells and various verterbrate fossils. I don't know much about the other zones, their description, how to identify them, or what is contained in them (if anything). thanks, Daryl.

Troodon Posted January 26, 2015 Share Posted January 26, 2015 Hi Daryl One reference that I use to describe the beds is a publication put out by the Calvert Museum called Fossils of Calvert Cliffs by Wallace Ashby. Not sure its still available. Link to comment Share on other sites More sharing options...

obsessed1 Posted January 26, 2015 Share Posted January 26, 2015 I know what you are referring to and I can't seem to find it either. Here is something worth reading through. It has lots of references listed that could prove useful in your search. http://pubs.usgs.gov/circ/2004/1264/html/trip9/index.html Link to comment Share on other sites More sharing options...

Metopocetus Posted January 26, 2015 Share Posted January 26, 2015 http://www.vmnh.net/products/details/id/44/catid/59/memoir-09 This is probably the most up to date description of the beds or zones. The authors discuss the original Shattuck Zones. Some of the zones have been lumped together, others have been "deleted", but the main fossil zones still exist like beds 10, 12, 14, 17, etc. Link to comment Share on other sites More sharing options...
cowsharks Posted January 26, 2015 Author Share Posted January 26, 2015 Thanks guys, collectively that's some great info and I don't think I own the one publication that Metopocetus linked. If I ever find that diagram I was referring to I'll post it back here. Daryl. Link to comment Share on other sites More sharing options...
