Sedimentary Facies, Architectural Elements and Trace Fossils of Kashkan Formation, Folded Zagros Zone in SW Iran

The Kashkan Formation (Paleocene to Middle Eocene), consists of conglomerate, sandstone, and siltstone in the Zagros Folded zone, southwest Iran. Type of the sedimentary facies, architectural elements and trace fossils show that Kashkan deposits were formed in a low sinuosity braided stream system, with north to south flow direction. The formation displays coarsening-upward succession reflects ...

Polystrate Fossils Require Rapid Deposition

Polystrate fossils are one of numerous evidences for the rapid deposition of strata, as opposed to the uniformitarian belief in slow deposition over millions of years. They are briefly described from the Joggins Formation, Nova Scotia; Yellowstone National Park, Montana and Wyoming; Ginkgo Petrified Forest State Park, Washington; the Geodetic Hills of Axel Heiberg Island; the Lompoc diatomite, ...

Expected Anomalies in the Fossil Record

The problem of intermediates in the fossil record has been frequently discussed ever since Darwin. The extent of 'gaps' (missing transitional stages) has been used to argue against gradual evolution from a common ancestor. Traditionally, gaps have often been explained by the improbability of fossilization and the discontinuous selection of found fossils. Here we take an analytical approach and ...
