Also known as Fisher and Henry collection
Where: Park County, Colorado (39.2° N, 106.2° W: paleocoordinates 0.3° S, 37.4° W)
• coordinate stated in text
• small collection-level geographic resolution
When: Belden Shale Formation, Morrowan (323.2 - 318.6 Ma)
• group of beds-level stratigraphic resolution
Environment/lithology: offshore; lithified, gray, calcareous shale and lithified, fine-grained, shelly/skeletal, sandy wackestone
•free-weathering and “crack-out” macrofossils from approximately
•8 to 10 ft of alternating, nodular, micritic limestone
•and shale. Lower limestone: skeletal carbonate
•mudstone, medium-dark-gray to dark-gray, weathering
•medium light gray to yellowish gray. Shale: medium-darkto
•dark-gray, slightly calcareous. Upper limestone (skeletal,
•brachiopodal, bryozoan wackestone to packstone):
•becoming more evenly bedded, slightly more skeletal,
•coarser grained, more sandy (containing quartz and feldspar
•grains), and thicker bedded upward, grading at top into
•fine-grained, pale-yellowish-brown-weathering, calcareous,
•skeletal, subarkosic sandstone; top beds make small
•ledges at ridge crest and on hillside.
Size class: macrofossils
