Despite the status of the eye as an "organ of extreme perfection", theory suggests that complex eyes can evolve very rapidly. The fossil record has, until now, been inadequate in providing insight into the early evolution of eyes during the initial radiation of many animal groups known as the Cambrian explosion. This is surprising because Cambrian(More)
The most abundant taxon of the Neoproterozoic soft-bodied biota near Ediacara, South Australia, occurs as clusters of similarly sized individuals, which suggests synchronous aggregate growth by spatfall. Tubes of Funisia dorothea gen. et sp. nov. were anchored within the shallow, sandy sea bed and lived in dense, typically monospecific concentrations. Tubes(More)
Kullingia is considered a key taxon in demonstrating the presence of terminal Protero-zoic–early Cambrian chondrophorine hydrozoans. However, Kullingia concentrica from the Lower Cambrian of northern Sweden possesses several features that show that it is not a body fossil but that it was formed by current or wave-induced rotation of an anchored tubular(More)
Bioturbation long has been 'blamed' for eliminating late Proterozoic-style sedimentary structures and fabrics. While the presence of diverse and complex burrows in lowermost Cambrian strata is indisputable, analysis of Precambrian– Cambrian successions in southeast Newfoundland demonstrate that this burrowing style did not produce typical Phanerozoic-style(More)
Vetulicolians are one of the most problematic and controversial Cambrian fossil groups, having been considered as arthropods, chordates, kinorhynchs, or their own phylum. Mounting evidence suggests that vetulicolians are deuterostomes, but affinities to crown-group phyla are unresolved. A new vetulicolian from the Emu Bay Shale Konservat-Lagerstätte, South(More)
Fossils of the Ediacara biota offer our earliest insight into diverse macroscopic life on this planet. In particular, given the diversity and range of exquisite soft-bodied preservation, the potential for unraveling aspects of the paleobiology and paleoecology is great. Clearly, however, there can be a taphonomic overprint that dictates how complete the(More)
