The range of Treptichnus pedum, the index trace fossil for the Treptichnus pedum Zone, extends some 4 m below the Global Standard Stratotype-section and Point for the base of the Cambrian Period at Fortune Head on the Burin Peninsula in southeastern Newfoundland. The identification of zigzag traces of Treptichnus isp., even further below the GSSP than T. pedum in the Fortune Head section, and in other terminal Proterozoic successions around the globe, supports the concept of a gradational onset… Expand
Proposed reassessment of the Cambrian GSSP
Since the time of its ratification in 1992, the Cambrian GSSP, 23 m above the base of Member 2A (Quaco Road Member) of the Chapel Island Formation, Fortune Head section, Newfoundland, Canada, hasExpand

Ichnological evidence for the Cambrian explosion in the Ediacaran to Cambrian succession of Tanafjord, Finnmark, northern Norway
Abstract The Ediacaran to Cambrian transition of the Digermul Peninsula consists of an ichnologically rich, thick, conformable, shallow marine siliciclastic succession that crosses theExpand

Ichnostratigraphy of the Ediacaran-Cambrian boundary: new insights on lower Cambrian biozonations from the Soltanieh Formation of northern Iran
Abstract. Strata in the Central Alborz Mountains, northern Iran, are interpreted to show continuous sedimentation from Ediacaran through Cambrian times. The Soltanieh Formation consists of fiveExpand

Gyrolithes from the Ediacaran-Cambrian boundary section in Fortune Head, Newfoundland, Canada: Exploring the onset of complex burrowing
Abstract The beginning of the Cambrian explosion is characterized by the onset of infaunalization and the appearance of systematic patterns of burrowing. The trace fossil Gyrolithes is common in theExpand
Environmental tolerance and range offset of Treptichnus pedum: Implications for the recognition of the Ediacaran-Cambrian boundary
The Ediacaran-Cambrian boundary, arguably the most important in the stratigraphic column, is based on the first appearance of the ichnospecies Treptichnus pedum . However, most trace fossils haveExpand

A candidate stratotype for the Precambrian-Cambrian boundary, Fortune Head, Burin Peninsula, southeastern Newfoundland
The Burin Peninsula exhibits an exceptionally thick and essentially continuous succession of marine strata through the Precambrian–Cambrian transition. Fossils are abundant and include trace fossils,Expand
Precambrian-Cambrian boundary global stratotype ratified and a new perspective of Cambrian time
The Precambrian-Cambrian boundary global stratotype is the base of the Phycodes pedum Zone at Fortune Head, southeastern Newfoundland. The initial, two-stage radiation of the Phanerozoic fauna (theExpand

Abstract: The discovery of intense bioturbation with ichnofabrics characterized by Teichichnus indicates a probable Cambrian age for the Swithland Formation of the Brand Group, the highest unit ofExpand

The youngest Ediacaran fossils from southern Africa.
The discovery of fossils of the Ediacara biota near the top of the Spitzkopf Member at farm Swanpunt extends the known range of these remains in Namibia more than 600 m to near the sub-Cambrian unconformity and provides support for the concept of the "Vendobionta" as a late Neoproterozoic group of mainly multifoliate organisms with a distinctive quilted segmentation.
