Neogene sharks and rays from the Brazilian ‘Blue Amazon’
The lower Miocene Pirabas Formation in the North of Brazil was deposited under influence of the proto-Amazon River and is characterized by large changes in the ecological niches from the early Miocene onwards. To evaluate these ecological changes, the elasmobranch fauna of the fully marine, carbonate-rich beds was investigated. A diverse fauna with 24 taxa of sharks and rays was identified with...
متن کاملQuaternary Morphology and Paleoenvironmental Records of Carbonate Islands
Here I use a simple numerical model of reef profile evolution to show that the presentday morphology of carbonate islands has developed largely in response to late Pleistocene sea level oscillations in addition to variable vertical motion and reef accretion rates. In particular, large amplitude 'ice-house' sea-level variability resulted in long lagoonal depositional hiatuses, producing the morp...
متن کاملNeogene origins and implied warmth tolerance of Amazon tree species
Tropical rain forest has been a persistent feature in South America for at least 55 million years. The future of the contemporary Amazon forest is uncertain, however, as the region is entering conditions with no past analogue, combining rapidly increasing air temperatures, high atmospheric carbon dioxide concentrations, possible extreme droughts, and extensive removal and modification by humans...
متن کاملPalynofacies analysis and paleoenvironmental interpretation of the Dalichai Formation, northeast of Semnan
Palynological and Palynofacies analysis combined with sedimentological studies have been performed on Dalichai Formation, northeast of Semnan, in order to define its paleoenviromental interpretation. Based on petrographic studies of organic matter, three palynofacies types were recognized as PF-1, PF-2, and PF-3. PF-1 is a characteristic of proximal shelf settings or basin. This palynofacies in...
متن کاملTrace Fossils from the Campanian - Maastrichtian Enugu Formation of the Anambra Basin, South-eastern Nigeria: Implications for Paleoenvironmental Interpretation
The Enugu Formation is a member of the Nkporo Group, and forms part of the basal stratigraphic unit of the Anambra Basin in south-eastern Nigeria. The Enugu Formation has been the subject of many studies concerning stratigraphy [1], depositional environments [2; Onuigbo et al. [3], organic geochemistry [4-6], paleoecology [7], palynology [7-9] and ichnology [10]. Nwajide & Reijers [2] were the ...
