Ediacaran macrofossils prior to the ~580 Ma Gaskiers glaciation in Newfoundland, Canada

چکیده

Macrofossils of the inferred protist-grade organism Palaeopascichnus linearis occur stratigraphically beneath glacial diamictites ~580 Ma, Gaskiers-equivalent, Trinity ‘facies’ Rocky Harbour Formation on Bonavista Peninsula Newfoundland, Canada. These fossils significantly pre-date previously reported macrofossils from Avalonia and extend taphonomic window for moldic preservation macroscopic organisms beyond Gaskiers event into middle Ediacaran Period. This finding confirms long stratigraphical range palaeopascichnid worldwide informs discussions surrounding both age poorly time-constrained units in Norway Australia, formal sub-division System.

Ediacaran discs from South America: probable soft-bodied macrofossils unlock the paleogeography of the Clymene Ocean

The origin, affinity and paleoecology of macrofossils of soft-bodied organisms of the terminal Ediacaran Period have been highly debated. Previous discoveries in South America are restricted to small shelly metazoans of the Nama Assemblage. Here we report for the first time the occurrence of discoidal structures from the Upper Ediacaran Cerro Negro Formation, La Providencia Group, Argentina. Sp...

Haootia quadriformis n. gen., n. sp., interpreted as a muscular cnidarian impression from the Late Ediacaran period (approx. 560 Ma)

Muscle tissue is a fundamentally eumetazoan attribute. The oldest evidence for fossilized muscular tissue before the Early Cambrian has hitherto remained moot, being reliant upon indirect evidence in the form of Late Ediacaran ichnofossils. We here report a candidate muscle-bearing organism, Haootia quadriformis n. gen., n. sp., from approximately 560 Ma strata in Newfoundland, Canada. This tax...

Are basal Ediacaran (635 Ma) post-glacial “cap dolostones” diachronous?

A layer of shallow-water dolostone (“cap dolostone”) with idiosyncratic sedimentary structures was deposited across continental margins world-wide in the aftermath of the terminal Cryogenian snowball Earth. The dolostone has a global average thickness of 18.5 m and is interpreted stratigraphically in different ways in the current literature: as diachronous (top and bottom) and tracking glacioeu...
