dow-orphan; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto" class=MsoNormal>The Early Cambrian Kuanchuanpu biota from southern Shaanxi of South China yielded a large number of three-dimensionally phosphatized animal embryos and Small Shelly fossils. These exceptionally preserved fossils have provided very important paleobiological insights into the study of metazoan evolution before the Cambrian explosion. Previous work on this biota mainly focused on systematic taxonomy and developmental biology, while the depositional environment and taphonomy of this biota has been largely ignored. In this paper, two taphonomic models are proposed: 1) chemical deposition; and 2) mechanical dynamic winnowing. The authors suggest that the Kuanchuanpu fossils are allochthonously preserved.
