Snoopyia insolita Community in the Montagne Noire (Silurian of France)

Where: France (47.5° N, 0.7° W: paleocoordinates 55.8° S, 43.0° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Monograptus transgrediens zone, Pridoli (423.0 - 419.2 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: marine; black, calcareous claystone and argillaceous limestone

• Many articulated shells. High infaunal content. All bivalves are susp. feeders; no deposit feeders. "Slow current activity is documented by the presence of common nektobenthic cephalopod shells...Articulated sheels indicate below wave base and periodic local events accompanied by abiotic conditions. Sed. rate high enough to cover small articulated shells.."
• "At the type locality shells occur in black, calcareous claystones to argillaceous limestones, with common cephalopod shells." No additional comment on lithology suggests, albeit not conclusively, that lithotypes are similar at Montagne Noire.

Collection methods: Life modes and abundances given for bivalves. List based only on this locality (table 16.16 and text).
