TL;DR: In this paper, the authors show that short-ranging fossils in widespread shallow-marine and paralic deposits indicate synchronous deposition of transgressive-regressive sequences in different parts of Euramerica and that these sequences correlate with glacial events in Gondwanaland at three levels.

TL;DR: Gondwanaland lasted from the late Neoproterozoic-Cambrian amalgamation of African and South American terranes to Antarctica through 320 Ma merging with Laurussia in Pangea to breakup from 185 to 100 Ma (Jurassic and Early Cretaceous).

TL;DR: In this article, a revised fit of East Gondwanaland prior to continental extension, and at various stages thereafter, was determined using bathymetric data combined with seismic and magnetic determinations of the continent-ocean boundaries off Australia, India and Antarctica.

TL;DR: Veevers et al. as discussed by the authors reconstructed the seafloor around Australia that spread during the dispersal of Argo Land, India, Antarctica, Lord Howe Rise/New Zealand and the Papuan Peninsula and determined the pattern of spreading around Australia was determined by two longstanding (earlier Phanerozoic) factors that operated in a counterclockwise direction: (1) penetration from the northwest by the Tethyan divergent ridge; and (2) rotation from the northeast of the Pacific convergent arc and back-arc.

TL;DR: In this paper, a time scale for the Neoproterozoic interval from isotopic variation of δ13C and δ34Ssulfate in seawater measured from reference columns in Canada and Australia was constructed.
