Textured organic surfaces associated with the Ediacara biota in South Australia
Abstract The Ediacaran Period takes its name from the fossils of the Ediacara biota, which represent the first appearance of large and diverse assemblages of organisms in the fossil record. AlthoughExpand

Ordovician increase in extent and depth of bioturbation: Implications for understanding early Paleozoic ecospace utilization
The infaunal habitat was colonized in the early Phanerozoic primarily by soft-bodied organisms. To understand the early biotic history of this environment, it is necessary to examine the overallExpand

A new hypothesis for organic preservation of Burgess Shale taxa in the middle Cambrian Wheeler Formation, House Range, Utah
Cambrian konservat-lagerstatten are the most significant fossil deposits for our understanding of the initiation of Phanerozoic life. Although many modes of preservation may occur, these depositsExpand
