Ejerslev, Mors (Hielscher coll) (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)

• Earliest Early Eocene "An Early Eocene age of 54.04 ± 0.14 Ma has been determined for layer +19 and 54.52 ± 0.05 Ma for layer −17 by the Ar40–Ar39 method (Chambers et al. 2003).

Environment/lithology: offshore ramp; lithified diatomite and volcaniclastic

• The depositional environment was in the Palaeocene–Eocene precursor of the North Sea, which was an almost or entirely enclosed inland body, open to the Atlantic at least at times (Bonde 1997).
• "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
