Monte Orobe, near Alsasua (IRSNB collection) (Cretaceous of Spain)

Where: Spain (42.9° N, 2.2° W: paleocoordinates 30.5° N, 1.9° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Late/Upper Albian (105.3 - 99.6 Ma)

• The new material described here is considered to be of late Albian age, following stratigraphic interpretations by López-Horgue et al. (1996; see also López-Horgue et al., 1999). It must be stressed that the exact stratigraphic ranges of decapod crustacean species recorded from Monte Orobe are still poorly known; compared to occurrences elsewhere, some species made their first appearance in the upper Albian, and ranged upwards into the lower Cenomanian. New fieldwork at Monte Orobe is needed to document the ranges in more detail.

• group of beds-level stratigraphic resolution

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

Size class: macrofossils
