Puerto de la Cadena (Pliocene of Spain)

Also known as Barranco del Cigarrón, Autovía

Where: Murcia, Spain (37.9° N, 1.2° W: paleocoordinates 38.0° N, 1.5° W)

• coordinate stated in text

When: CI-10 Member (Cigarron Formation), Early/Lower Pliocene (5.3 - 3.6 Ma)

Environment/lithology: "floodplain"; medium-grained, coarse, conglomeratic sandstone

• the Puerto de la Cadena, microfossils are concentrated in vegetated areas of the floodplain
• The Cigarrón Unit at the Puerto de la Cadena site is represented by a sand and lutite alternating succession (Fig. 2). The sandy facies association is characterized by coarse sediments (mainly sands, but also microconglomerates and conglomerates), that are mainly organized in sets of trough and planar cross-stratification. These sets have a thickness of between a few centimeters and a meter, and most of them have an erosive base that exhibits a basal lag with intraformational mud clasts, fragmentary bones and plant fossil remains. They fine upwards, with frequent reactivation surfaces.

•The macrovertebrate fossil remains are mainly located in the conglomeratic layers of the sands or in the basal lag of the sedimentary sets. The sand components are medium-sized to coarse siliciclastic grains with very little matrix and no cement. Cross-bedding in the sed- imentary sets exhibits internal lamina that are variably inclined, from quasi-horizontal to 30°, and in most cases points towards N55°E.

Size classes: macrofossils, mesofossils, microfossils
