Monte Bolca (MNHN Paris Bol. collection) (Eocene of Italy)

Where: Italy (45.6° N, 11.2° E: paleocoordinates 39.3° N, 9.6° E)

• coordinate based on nearby landmark

When: Lutetian (47.8 - 41.3 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; lithified, shelly/skeletal limestone

• "The fossil-bearing section consits of several calcareous units (Figure 20.2). Exceptionally well preserved fossils are derived from units of laminated sheet limestones unlain by reefal limestones. Fish and plant fossils can be found at five levels. The beds containing fish and plant fossils show a varved structure in which relatively thick biomicritic laminae alternate in a regular pattern with very thin micritic laminae, which are homogenous and slightly clayey. The thicker biomicritic laminae contain silt-sized particles and foraminifera, ostracods, molluscs, and small thin-shelled gastropods. These biomicritic laminae are gradational with the micritic laminae, producing a graded bedding texture for each pair of laminae. Finely disseminated pyrite and bitumen can be found in these laminated beds. (pg. 369)"
