Galeorhinus Cuvieri
''Galeorhinus cuvieri'' (named after Georges Cuvier) is an Extinction, extinct species of houndshark known from the Ypresian, Early Eocene-aged Monte Bolca site of Italy. It was a close relative of the modern Tope Shark, tope or school shark, which it is highly morphologically similar to. Ecology It is known from six extremely well-preserved specimens that preserve the full body of the shark. A comparison to the modern school shark suggests that these all represent sexually immature juvenile individuals, indicating that the Bolca site may have represented a nursery for a population of ''G. cuvieri''. One particularly well-preserved specimen has preserved soft tissues and even preserved stomach contents, which appear to be of a barracuda (''Sphyraena bolcensis''). As reef-dwelling populations of the modern school shark also show a preference for feeding on barracudas, this suggests a long history of predator-prey interactions between these two genera. Taxonomy This species has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Eocene
In the geologic timescale the Ypresian is the oldest age (geology), age or lowest stage (stratigraphy), stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the Lower Eocene (Early Eocene). Events The Ypresian Age begins during the throes of the Paleocene–Eocene Thermal Maximum (PETM). The Fur Formation in Denmark, the Messel shales in Germany, the Oise amber of France and Cambay amber of India are of this age. The Eocene Okanagan Highlands are an uplands subtropical to temperate series of lakes from the Ypresian. The Ypresian is additionally marked by another warming event called the Early Eocene Climatic Optimum (EECO). The EECO is the longest sustained warming event in the Cenozoic record, lasting about 2–3 million years between 53 and 50 Ma. The interval is characterized by low oxygen-18 isotopes, high levels of atmospheric pCO2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giovanni Serafino Volta
Giovanni Serafino Volta (1764–1842) was an Italian priest, naturalist, and palaeontologist, best known for his studies of fossil fish from Monte Bolca. Volta was an ''Abate'' (or abbot) and theologian. He was a Canon of the Imperial Basilica in Mantua and the curator of the natural history department at the University of Pavia. He wrote ''Ittiolitologia Veronese del Museo Bozziano ora annesso a quello del Conte Giovambattista Gazola e di altri gabinetti di fossili Veronesi con la versione Latina'', published at Verona between 1796 and 1809. Illustrated with 76 fine plates this is the first treatise on fossil ichthyology in Italy and describes 123 species of fossil fish from the fossil site of Monte Bolca.

Eocene Fish Of Europe
The Eocene ( ) is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in com ...

Physogaleus
''Physogaleus'' is an extinct genus of small requiem shark that lived from the Late Paleocene to Miocene epochs. Description ''Physogaleus'' is only known from fossil teeth and isolated vertebra. The teeth are similar to those of the modern Tiger shark, but are smaller, with a more central cusp that projects further from the base of the tooth. The species of ''Physogaleus'' were originally described as belonging to the same genus as the modern Tiger shark, ''Galeocerdo ''Galeocerdo'' is a genus of ground shark. Only a single species, ''G. cuvier'', the tiger shark, is extant. The earliest fossils date back to the early Eocene epoch, (Ypresian), around 56–47.8 Million years ago.

Galeorhinus
''Galeorhinus'' is a genus of houndshark containing one extant species, the widespread but highly threatened school shark (''G. galeus''), and several extinct species dating back to the Late Cretaceous (Cenomanian). The majority of extinct species are known only from fossil teeth, but the Early Eocene-aged species '' G. cuvieri'' is known from extremely well-preserved full-body specimens from Monte Bolca, Italy. The oldest known species is '' G. glickmani'' from the Cenomanian of Russia.
