Disparity Changes in 370 Ma Devonian Fossils: The Signature of Ecological Dynamics?
Early periods in Earth's history have seen a progressive increase in complexity of the ecosystems, but also dramatic crises decimating the biosphere. Such patterns are usually considered as large-scale changes among supra-specific groups, including morphological novelties, radiation, and extinctions. Nevertheless, in the same time, each species evolved by the way of micro-evolutionary processes...

متن کاملAlborziphyllinae, A New Late Devonian Rugose Corals Subfamily
Members of the family Laccophyllidae are small, solitary rugose corals with stratigraphic ranges from Silurian to Permian. Among the laccophyllids, axial ends of major septa are united in an aulos and dissepiments may be absent or present. Minor septa can be contratingent and sometimes are small or in some genera are absent. Septa and aulos may be thick or thin. In this study, Famennian rugose...
متن کاملThe Origin of Mammals: A Study of Some Important Fossils
For many years evolutionists have pointed to the alleged transition of reptiles to mammals as being the best example of the natural origin of a major taxon. At first sight such claims appear to have considerable justification, but when the fossil evidence is closely examined it can be shown that there are some grave deficiencies, and the claim is not only factually unproved but also contains a ...
