The Influence of Silurian-Devonian Climates on the Rise of Air-Breathing Vertebrates.
beyond what was laid down by the rivers in time of flood to maintain their grade across the sinking basins was carried through to the shallow sea which lay on the surface of the continent to the southwest. The relations were somewhat similar to those which now prevail between the ranges of the North American Cordillera and the Tertiary basins which lay between them and especially on the west be...
متن کاملEnd-Devonian extinction and a bottleneck in the early evolution of modern jawed vertebrates.
The Devonian marks a critical stage in the early evolution of vertebrates: It opens with an unprecedented diversity of fishes and closes with the earliest evidence of limbed tetrapods. However, the latter part of the Devonian has also been characterized as a period of global biotic crisis marked by two large extinction pulses: a "Big Five" mass extinction event at the Frasnian-Famennian stage b...
متن کاملPALEOBIOGEOGRAPHY: The Relevance of Fossils to Biogeography
■ Abstract Paleobiogeography has advanced as a discipline owing to the increasing utilization of a phylogenetic approach to the study of biogeographic patterns. Coupled with this, there has been an increasing interdigitation of paleontology with molecular systematics because of the development of techniques to analyze ancient DNA and because of the use of sophisticated methods to utilize molecu...
متن کاملConservation paleobiogeography: the past, present and future of species distributions
species distributions even more than the limits of their fundamental niches: interspecific interactions, dispersal limitations, and disequilibrium or historical contingencies (Fig. 1; Peterson et al. 2011). Occasionally, there may also be situations where a species distribution strays outside of its fundamental niche, for example in the cases of facultative interactions or sink populations (Fig...
متن کاملGlyptolepis from the Middle Devonian of Scotland
The Rhipidistia (Osteichthyes, Crossopterygii) comprise three superfamilies of Paleozoic fossil fishes, the Holoptychoidea, Osteolepoidea and Rhizodontoidea. Of these the members of the Holoptychoidea (families Holoptychidae and Porolepidae) are by far the least well known, and consequently there exists a considerable gap in our knowledge of the evolution of the Rhipidistia as a whole. The aim ...
