Ribota (East) (Jurassic to of Spain)

Also known as RB

Where: Castilla y León, Spain (41.9° N, 1.9° W: paleocoordinates 33.1° N, 8.3° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Matute Formation, Late/Upper Tithonian to Late/Upper Tithonian (150.8 - 140.2 Ma)

• "lower part of the lacustrine carbonates of the Matute Fm."

• bed-level stratigraphic resolution

Environment/lithology: lacustrine; wackestone

• "wackestone limestones" "Isolated calcite and dolomite crystals can be found dispersed in a chlorite-dominated matrix, where clay mineral crystals show no preferred orientation. Secondary idiomorphic pyrite crystals of variable size, from sub-millimetric to centimetric, have grown both in the matrix and inside the bone elements."

Size classes: macrofossils, mesofossils

Preservation: replaced with calcite, replaced with silica

Collection methods: surface (float), surface (in situ),
