The architecture of Ediacaran Fronds
Abstract:  Ongoing discoveries of new rangeomorph fossils from the Ediacaran of Avalonia allow us to put forward a unified and approachable scheme for the description and phylogenetic analysis ofExpand

First evidence for locomotion in the Ediacara biota from the 565 Ma Mistaken Point Formation, Newfoundland
Evidence for locomotion in the Precambrian fossil record is scant. Reliable Ediacaran trace fossils are all younger than 560 Ma, and consist of relatively simple horizontal burrows and trails fromExpand

A new assemblage of juvenile Ediacaran fronds from the Drook Formation, Newfoundland
A new assemblage of frondose and filamentous Ediacaran macrofossils is reported from the upper Drook Formation of Pigeon Cove, Newfoundland. The frondose forms, all less than 3 cm in length, areExpand

Reconstructing the reproductive mode of an Ediacaran macro-organism
Enigmatic macrofossils of late Ediacaran age (580–541 million years ago) provide the oldest known record of diverse complex organisms on Earth, lying between the microbially dominated ecosystems ofExpand

FRAMBOIDAL PYRITE SHROUD CONFIRMS THE ‘DEATH MASK' MODEL FOR MOLDIC PRESERVATION OF EDIACARAN SOFT-BODIED ORGANISMS
Abstract The mechanisms by which soft-bodied organisms were preserved in late Ediacaran deep-marine environments are revealed by petrographic and geochemical investigation of fossil-bearing surfacesExpand

Resolving MISS conceptions and misconceptions: A geological approach to sedimentary surface textures generated by microbial and abiotic processes
The rock record contains a rich variety of sedimentary surface textures on siliciclastic sandstone, siltstone and mudstone bedding planes. In recent years, an increasing number of these textures haveExpand

Integrated records of environmental change and evolution challenge the Cambrian Explosion
The ‘Cambrian Explosion’ describes the rapid increase in animal diversity and abundance, as manifest in the fossil record, between ~540 and 520 million years ago (Ma). This event, however, is nestedExpand

The Beothukis/Culmofrons problem and its bearing on Ediacaran macrofossil taxonomy: evidence from an exceptional new fossil locality
The late Ediacaran siliciclastic successions of eastern Newfoundland, Canada, are renowned for their fossils of soft-bodied macro-organisms, which may include some of the earliest animals. DespiteExpand

Quantitative study of developmental biology confirms Dickinsonia as a metazoan
The late Ediacaran soft-bodied macroorganism Dickinsonia (age range approx. 560–550 Ma) has often been interpreted as an early animal, and is increasingly invoked in debate on the evolutionaryExpand

The origin of animals: Can molecular clocks and the fossil record be reconciled?
The evolutionary emergence of animals is one of the most significant episodes in the history of life, but its timing remains poorly constrained. Molecular clocks estimate that animals originated andExpand
