Spatangus Brissus
''Spatangus'' is a genus of heart urchins in the Spatangidae family.Hansson, H. (2009)Spatangus Gray, 1825 Accessed through the World Register of Marine Species on 2 August 2010 The genus is synonymous with the previously recognised genera ''Prospatangus'' Lambert, 1902 and ''Spatagus''. There are nine recognised species. The type species is ''Spatangus purpureus'' Müller, 1776 by subsequent designation (Rowe & Gates, 1995). ''Spatangus'' comprises marine heart urchins that feed on subsurface deposits and graze. Fossil of heart urchins of this genus have been found in the sediments of Europe, United States, Egypt and Australia from Cretaceous to Pliocene (age range: 85.8 to 2.588 Ma). Species Species within this genus include: * ''Spatangus altus'' Mortensen, 1907 * '' Spatangus baixadoleitensis'' Maury, 1934a † * ''Spatangus beryl'' Fell, 1963 * '' Spatangus brissus'' * ''Spatangus californicus'' H.L.

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Santonian Genus First Appearances
The Santonian is an age in the geologic timescale or a chronostratigraphic stage. It is a subdivision of the Late Cretaceous Epoch or Upper Cretaceous Series. It spans the time between 86.3 ± 0.7 mya ( million years ago) and 83.6 ± 0.7 mya. The Santonian is preceded by the Coniacian and is followed by the Campanian.Gradstein ''et al.'' (2004) Stratigraphic definition The Santonian Stage was established by French geologist Henri Coquand in 1857. It is named after the city of Saintes in the region of Saintonge, where the original type locality is located. The base of the Santonian Stage is defined by the appearance of the inoceramid bivalve ''Cladoceramus undulatoplicatus''. The GSSP (official reference profile) for the base of the Santonian Stage is located near Olazagutia, Spain; it was ratified by the Subcommission on Cretaceous Stratigraphy in 2012. The Santonian's top (the base of the Campanian Stage) is informally marked by the extinction of the crinoid '' Mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
