A0418a. Jumpers section (Silurian of Canada)

Also known as A0105

Where: Quebec, Canada (49.4° N, 62.2° W: paleocoordinates 22.7° S, 33.0° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Pavillon Member (Jupiter Formation), Telychian (438.5 - 433.4 Ma)

• Collection A418 of Dewing 1999. Same collection names are used by Jin 1989, Jin and Zhan 2008, and Li and Copper 2006.

•The collection is noted by Dewing to be from the Jupiter and Chicotte fms., spanning the Pavillon Mbr. and the lower Chicotte Fm. We marked here the lowest Mbr. because we do not know which one the fossils came from.

•Outcrop at contact Pavillon and Chicotte (Ebbestad & Tapanilla 2005).

• bed-level stratigraphic resolution

Environment/lithology: lithified, calcareous lime mudstone

• Member description taken from 2007 Long. Tempestite frequency curves: a key to Late Ordovician and Early Silurian subsidence, sea-level change, and orbital forcing in the Anticosti foreland basin, Quebec, Canada. Can. J. Earth Sci. Vol. 44, 413-431. "The 10 to 12 m thick Pavillon Member consists of recessive calcareous mudstone and interbedded micrite, with discontinuous lenses of calcarenite."

•"530 cm blue-grey thin, irregular bed lenticular coquinoids, calcarenites and 40% soft fossils, blue-grey shale with diverse brachiopods. Uppermost 30 cm with Costistricklandia."

Size classes: macrofossils, mesofossils

Preservation: original calcite

Collected by P. Copper; reposited in the GSC

Collection methods: bulk,
