***
Brief statement of problem and remarks (from collector):
Are any of these Devonian? RR152 is critical, because if it is Lisburne it will prove a major overthrust.

66ABe75 is from a fenster in Devonian rocks. If 66ABe24 is Mississippian it indicates another fenster.

Be316 is uppermost Lisburne: post-Mississippian? Could any of the collections assigned to Kayak(?) really be Permian? We need control badly in these shales.
