Abstract
This paper provides a guide to measured sections of Upper Devonian (Famennian) and Mississippian (Kinderhookian, Osagean, and Meramecian) rocks visited on a three-day field trip between Provo, Utah, on the Wasatch Front and the Crawford Mountains in the Overthrust Belt along the Utah-Wyoming State line. The field trip, sponsored by the Pander Society, was held on April 30-May 2, 1978 in conjunction with the meeting of the Rocky Mountain section of the Geological Society of America at Provo, Utah. The rocks that may be sampled for conodonts are represented by the Middle to Upper Scaphignathus velifer (middle Famennian) through Cavusgnathus (middle Meramecian) conodont Zones. The measured sections and field trip provide a west to east traverse of the Sevier thrust system. The sections demonstrate the biostratigraphic, paleogeographic, and sedimentational differences among equivalent Famennian rocks as well as the transition from the Osagean and early Meramecian starved phosphatic basin on the west to time-equivalent carbonate rocks of the shelf margin on the east.
