Vertebrate Paleontology of Texas Caves
Vertebrate fossils from Texas caves have been studied for over 75 years. In that time few summary treatments of Texas caves and their fossil faunas have been published. The only reviews focusing specifically on Texas cave vertebrate paleontology sites were written over 20 years ago (Frank, 1964; Lundelius and Slaughter, 1971). Much work on cave sites in Texas has occurred since these reviews. S...
متن کاملAvian Paleontology and Evolution
Miocoracias chenevali, nov. gen., nov. spec., a new genus and species of roller (Aves: Coraciiformes s. s.: Coraciidae) is described from the Early Miocene of Saint-Gérand-le-Puy. This family had not yet been reported from the rich fossil avifauna of this area. Although the material is fragmentary it shows morphological characteristics different from those of the extinct family Geranopteridae, ...
متن کاملProdromus of Vertebrate Paleontology of Bermuda
Bermuda is an isolated oceanic island situated 1000 km ESE of Cape Hatteras, North Carolina (Fig. 1, inset). Its volcanic core, last active during the Oligocene (Reynolds & Aumento, 1974), was probably subaerial for some of its existence because rare basaltic pebbles and a small percentage of volcanic grains have been found in surface deposits. Apart from the initial volcanic origin of Bermuda,...
متن کاملVertebrate Paleontology of the Cloverly Formation (Lower Cretaceous), II: Paleoecology
Vertebrate microfossil assemblages in terrestrial formations are a promising source of data on the structure of fossil metacommunities. However, the degree to which these deposits capture true, metacommunity-level samples is unknown. Individual deposits may be biased in ways that limit their utility for intraand inter-formation comparisons. This study describes the composition of ten vertebrate...
متن کاملEvolution in fossil lineages: paleontology and The Origin of Species.
Of all of the sources of evidence for evolution by natural selection, perhaps the most problematic for Darwin was the geological record of organic change. In response to the absence of species-level transformations in the fossil record, Darwin argued that the fossil record was too incomplete, too biased, and too poorly known to provide strong evidence against his theory. Here, this view of the ...
