Maria Peres, marly limestones with Leptaena fauna (Jurassic of Portugal)

Also known as Rabacal, Zambujal

Where: Portugal (40.1° N, 8.5° W: paleocoordinates 31.0° N, 4.1° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: S. Gião Formation, Tenuicostatum (183.0 - 182.0 Ma)

• Nannirhynchia pygmaea occurs in the Polymorphum Zone [= Tenuicostatum Zone] of the S. Gio Formation [= Margas calcarias de S. Giao (Barbosa et al. 1988)]. Duarte & Soares (2002) subdivided this formation into five members, of which according to Soares et al. (2007), the member "marly limestones with Leptaena fauna" [= Bed 40c (Mouterde et al. 1964–65) = MST1 (Duarte 1995, 1997)], yielded N. pygmaea.

• group of beds-level stratigraphic resolution

Environment/lithology: offshore ramp; lithified marl

Size class: macrofossils

Preservation: mold/impression, replaced with pyrite
