Biomineralized skeletons are widespread in animals, and their origins can be traced to the
latest Ediacaran or early Cambrian fossil record, in virtually all animal groups. The origin of …

Abstract The lower Middle Cambrian of Scandinavia is reviewed and subjected to sequence
stratigraphical analysis. Sequences are defined as transgressive–regressive depositional …

A longstanding question in paleontology has been the influence of calcite and aragonite
seas on the evolution of carbonate skeletons. An earlier study based on 21 taxa that evolved …

Assemblages of mineralized skeletal fossils are described from limestone rocks of the lower
Cambrian Nemakit-Daldyn, Medvezhya, Kugda-Yuryakh, Manykay, and lower Emyaksin …

Similarities in biotic successions support a unified, composite chronostratigraphy for the
Lower-Middle Cambrian of the Iberian and Moroccan margins of West Gondwana. The …

An assemblage of mineralised skeletal fossils containing molluscs, hyoliths, halkieriids,
chancelloriids, tommotiids, lobopodians, paleoscolecids, bradoriids, echinoderms …

Rodinia break-up with late Ediacaran rifting defined a NE Laurentia triple junction (New York
Promontory–Ottawa–Bonnechere aulacogen (OBA)–Quebec Reentrant). Rifting persisted to …

Limestone erratics in the Early Miocene glacio− marine Cape Melville Formation of King
George Island, West Antarctica, have yielded Early and Middle Cambrian small skeletal …

Abstract The Taconian Humber Zone stretches from western Newfoundland to southern
Quebec. The Early Cambrian slope succession in Newfoundland is found in the Curling …

The Henson Gletscher Formation of North Greenland yields moderately diverse trilobite
faunas which bracket the Cambrian Series 2–Series 3 boundary interval. A number of the …
