Ejerslev Molergrav, Mors, between ash layers -11 and -13 (Eocene of Denmark)

Where: Denmark (56.9° N, 8.9° E: paleocoordinates 52.4° N, 5.6° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Fur Formation, Ypresian (56.0 - 47.8 Ma)

• "The Danish insects discussed here are from the marine Fur Formation, about 50-60 m of diatomite and tephra layers, which, with the Ølst Formation, constitute the Mo-clay in the northern Jutland region" Archibald & Makarkin, 2006

Size class: macrofossils

Preservation: adpression
