east of Chilton Chine (Cretaceous of the United Kingdom)

Where: England, United Kingdom (50.6° N, 1.4° W: paleocoordinates 40.9° N, 9.3° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Wessex Formation (Wealden Group), Barremian (129.4 - 125.0 Ma)

• "likely from an unnamed layer between the Brighstone and Chilton Chine Sandstones"

• bed-level stratigraphic resolution

Environment/lithology: fluvial; fine-grained, intraclastic sandstone

• "The sandstone matrix surrounding this specimen is largely fine-grained but does include small clasts; comparatively little plant debris (usually typical of the plant debris beds) was present during preparation"

Size class: macrofossils
