The first evidence of trace fossils and pseudo-fossils in the continental interlava volcaniclastic sediments on the Faroe Islands

Interlava volcaniclastic sediments, mostly sandstones, from the Palaeogene Faroe Islands Basalt Group (Malinstindur and Sneis Formations) contain rare ichnofauna and well-preserved pseudofossils in the form of linear structures. Five specimens of two ichnogenera have been identified, which include H...

Description
Summary:Interlava volcaniclastic sediments, mostly sandstones, from the Palaeogene Faroe Islands Basalt Group (Malinstindur and Sneis Formations) contain rare ichnofauna and well-preserved pseudofossils in the form of linear structures. Five specimens of two ichnogenera have been identified, which include Helminthoidichnites isp. and ?Palaeophycus isp. The linear structures are interpreted to be desiccation cracks. This association indicates an environment with low to moderate hydrodynamic energy, which confirms a mosaic landscape of floodplains with rivers and shallow lakes.
