Definition. Acritarchs were originally defined as non-acid soluble (i.e. non-carbonate, non-siliceous) organic-walled microfossils consisting of a central cavity, and whose biological affinities cannot be determined with commonly they are composed of thermally altered acid insoluble carbon compounds ().Acritarchs may include the remains of a wide range of quite different kinds Domain: Eukaryota.

Peel, Sebastian Willman, Stig A. Schack Pedersen. The early Cambrian (ca. Ma) Sirius Passet Lagerstätte of North Greenland is one of the most celebrated sites bearing fossils of soft-bodied organisms, and provides key insights into the Cambrian explosion of animal life.

Unlike the younger Burgess Shale ( Ma), the Sirius Passet biota does not preserve original carbonaceous material because of its history of metamorphic by: 5.

The lower contact of the Upper Cambrian Kurchavinskaya Formation is also conformable.

Fitch, Francisco J. Ayala. The marine offshore shelf mudstones of the Early Cambrian Buen Formation at Sirius Passet, North Greenland, contain a rich Konservat-Lagerstätte which includes abundant well-preserved material of the bivalved arthropod Isoxys volucris new species.

Buenellus higginsi is an average size (about 5 centimetres or inches) trilobite, which lived during the Lower Cambrian period, in what is now North-West is a prominent member of the Sirius Passet fauna.

The Lower Cambrian Buen Formation is composed of tidally influenced and storm-derived sandstones that pass upward into lower-energy, deeper-water mudstones. Northward, toward the slope, the formation passes into more ubiquitous mudstone facies, and, at the shelf-slope break, black and green outer-shelf mudstones give way to the variegated.

Aaveqaspis is a genus of small (about centimetres or inch long) marine arthropods of unclear affiliation, that lived during the early Cambrian period. Fossil remains of Aaveqaspis were collected from the Lower Cambrian Sirius Passet fossil-Lagerstätte of North Greenland.

Aaveqaspis looks like a soft eyeless trilobite with a weakly defined axis, a headshield (or cephalon) with stubby Class: incertae sedis. “The occurrence of dinoflagellate-related steranes was also observed in the extracts and kerogen pyrolysates of two additional samples from the Lower Cambrian Buen Formation in North Greenland and the upper Riphean Visingo Beds (lower part) from Sweden.

The segment of the basin exposed in North Greenland is approximately km long and has a maximum preserved north-south width of km. The thickness of the sedimentary column reaches about 8 km; the main part of the succession is of Cambrian-Silurian age, but it may extend down into the latest Precambrian and up into the earliest Devonian.

During the early Cambrian, Sirius Passet lay on the northern margin of Laurentia, at a palaeolatitude of around 15° S (Cocks & Torsvik ).This segment of the Greenland–Canada margin is commonly referred to as the Franklinian Basin (Higgins et al.
