Data from: Small Carbonaceous Fossils (SCFs) from North Greenland: new light on metazoan diversity in early Cambrian shelf environments
The Sirius Passet Lagerstätte of North Greenland provides one of the oldest records of soft-bodied metazoan-dominated ecosystems from within the early Cambrian. The Lagerstätte site itself is restricted to just a single ~1 km-long outcrop located offshore from the shelf margin, in an area that has b...

The Sirius Passet Lagerstätte of North Greenland provides one of the oldest records of soft-bodied metazoan-dominated ecosystems from within the early Cambrian. The Lagerstätte site itself is restricted to just a single ~1 km-long outcrop located offshore from the shelf margin, in an area that has been affected by metamorphic alteration during the Ellesmerian Orogeny (Devonian–Early Carboniferous). The recent recovery of Small Carbonaceous Fossils (SCFs) to the south in areas that have escaped the effects of this deformation has substantially expanded the known coverage of organic preservation into shallower-water depositional settings in this region. Here we describe additional SCF assemblages from the siliciclastic shelf succession of the Buen Formation (Cambrian Series 2, Stages 3-4; ∼ 515 Ma), expanding upon the previously documented SCF biota.
