Barranco de Ramals, near La Puebla de Roda (MPZ collection) (Eocene of Spain)

Where: Spain (42.3° N, 0.5° E: paleocoordinates 37.6° N, 1.1° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Serraduy Formation, Ypresian (56.0 - 47.8 Ma)

• The material described herein was collected from the lower Eocene (middle Ypresian) Serraduy Formation of the Tremp-Graus Basin

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified limestone

• This specific locality corresponds to a reef environment that has already yielded a wide range of decapod crustaceans (Artal and Via, 1989; Artal and Castillo, 2005a; Artal and Van Bakel, 2018a, b; Ferratges et al., 2019).

• Specimens were collected from the outcrop that exposes the transition between the reef limestones and the overlying Riguala Marls at a locality known as “Barranco de Ramals.”

Size class: macrofossils

Collected in 2018-2019

• Repository: Museo de Ciencias Naturales de la Universidad de Zaragoza (MPZ)
