Microbial mats in terminal Proterozoic siliciclastics; Ediacaran death masks
A variety of sedimentary structures and patterns in Proterozoic siliciclastic sedimentary rocks cannot be explained by known inorganic processes. In particular, certain bed-surface textures, andExpand

Paleoecology of the oldest known animal communities: Ediacaran assemblages at Mistaken Point, Newfoundland
Abstract Ediacaran fossils at Mistaken Point, southeastern Newfoundland (terminal Neoproterozoic; 565–575 Ma) represent the oldest known animal communities. In contrast to most Phanerozoic fossilExpand

The Ediacaran emergence of bilaterians: congruence between the genetic and the geological fossil records
Unravelling the timing of the metazoan radiation is crucial for elucidating the macroevolutionary processes associated with the Cambrian explosion. Because estimates of metazoan divergence timesExpand

Paleoenvironmental analysis of the late Neoproterozoic Mistaken Point and Trepassey formations, southeastern Newfoundland
The Mistaken Point and Trepassey formations (Conception and St. John's groups, respectively) comprise a terminal Neoproterozoic, deep-marine succession of fine-grained turbidites and volcanogenicExpand

Complex trace fossils from the terminal Proterozoic of Namibia
We document for the first time the occurrence of the complex trace fossil Treptichnus from the terminal Proterozoic Nama Group, Namibia. These traces differ in detail from the Cambrian index fossilExpand
