Castle Eden boulder clays (Pleistocene to of the United Kingdom)

Where: Durham, United Kingdom (54.7° N, 1.3° W: paleocoordinates 54.8° N, 1.4° W)

When: Castle Eden Fissure-Fill Formation, Calabrian to Calabrian (1.8 - 0.1 Ma)

• Dated as Upper Pliocene by Lesne, but the "Castle Eden flora" suggests an Early Pleistocene age, which is supported by the identification of Mammuthus meridionalis, an elephant that was common in Europe during the Early Pleistocene up to the Cromerian (MacMillan et al., 2010). [Early Pleistocene likely used in previous sense, i.e. excluding the Gelasian]

• group of beds-level stratigraphic resolution

Environment/lithology: fissure fill; unlithified siliciclastic sediments

Size class: macrofossils

Collected by Eleanor M. Reid in 1920

• Repository: not stated (possibly MNHN if Lesne retained the material)
