Unit 5 - TH4 and BH5, Punta S'Argiola (Ordovician of Italy)

Also known as Dom 2b, `Punta S'Argiola'. Cyclopygid Bed

Where: Sardinia, Italy (30.3° N, 8.7° E: paleocoordinates 74.0° S, 114.3° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Amorphognathus ordovicicus conodont zone, Punta S'Argiola Member (Domusnovas Formation), Kralodvorian (449.5 - 445.6 Ma)

• BA 5/6 Foliomena community. Listed as upper Kralodvorian; Domusnovas overlies Portixeddu Formation.

• formation-level stratigraphic resolution

Environment/lithology: offshore shelf; lithified, shelly/skeletal, calcareous mudstone

• Fossiliferous, dark, reddish-gray, slightly calcareous mudstone

Size classes: macrofossils, mesofossils

Collection methods: BA 5/6 Foliomena community; Member occurs in five outcrops, but is only .89 to 1.5 meters thick, (on average 1.1 m). All the photographed specimens come from these two locations (only approx. 15 km apart) and so I will consider this a pooled sample, despite more than one location.
