Sample IR2, Irañeta-W section (Cretaceous of Spain)

Where: Spain (42.9° N, 2.0° W)

• Paleocoordinates: 39.2° N, 16.5° E (Wright 2013)

• coordinate estimated from map

• small collection-level geographic resolution

When: Zhuganpo Member (Falang Formation), Late/Upper Albian (105.3 - 99.6 Ma)

• The age of this succession is early late Albian based on ammonoids from correlative successions to the east and west

• bed-level stratigraphic resolution

Environment/lithology: slope; lithified packstone

• Crinoid specimens were transported down the carbonate slope, so they represent resedimented associations (FA 4) but were likely from the fore-reef, where autochthonous limestones of FA 3 were deposited. The fact that crinoids were just transported a bit farther from their living area is also supported by the low abrasion on specimens, absence of sorting, and the high degree of articulation.
• Debrite (breccia)-calcarenite beds

Size class: macrofossils

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