Rasal locality, Ainsa-Jaca Basin, coral rudstone facies (Eocene of Spain)

Where: Spain (42.4° N, 0.6° W: paleocoordinates 41.0° N, 3.8° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Arguis Formation, Priabonian (38.0 - 33.9 Ma)

• Lower Priabonian

Environment/lithology: reef, buildup or bioherm; packstone and rudstone

• Coral rudstone, with packstone matrix, occurs in thin to thick beds (20 to 50 cm, rarely 1 m) commonly at the flanks and top of the buildups, often associated with SP lithofacies, and locally intercalated with clay-marls (lithofacies CM) at the base of some small mounds. Common components are coral fragments (mostly branching and phaceloid corals; Fig. 7A and B), laminar red algae and red-algal fragments, encrusting bryozoans and foraminifera
• Coral rudstone, with packstone matrix

Size class: macrofossils
