Las Hoyas (MCCM collection) (Cretaceous of Spain)

Where: Castilla-La Mancha, Spain (40.1° N, 1.9° W)

• Paleocoordinates: 26.9° N, 21.3° E (Wright 2013)

• coordinate estimated from map

• outcrop-level geographic resolution

When: La Huérguina Formation, Late/Upper Barremian (130.0 - 125.5 Ma)

• also called "Calizas de La Huérgina Formation" or "La Huérgina Limestones Formations"

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - large; limestone and packstone

• shallow to deep lacustrine facies; "produced in the context of a continental (freshwater) subtropical, seasonal summer wet, carbonate wetland that overlay a low-relief karstic terrain. The wetland was drained by carbonate-rich freshwater and comprised a typical environmental mosaic of swampy plains, ponds, lakes, ephemeral channels and sloughs."
• Limestone with laminates; three facies described: Massive limestone, packstones with peloids and sand-sized fragments of Charophyte stems. Occasionally, in the base of these beds, levels of gastropodal wackestones appear; Flaggy limestones, sometimes nodular. Ostracodal mudstones with occasional thick laminations, laterally grading to confolute laminations; Laminated limestones, mudstones with laminations containing abundant fossils. Laminae are very continuous laterally

Size classes: macrofossils, mesofossils

Preservation: adpression, trace, soft parts

Collection methods: quarrying, surface (in situ),

• Repository: Museo de las Ciencias de Castilla-La Mancha, Cuenca (MCCM)
