Arthaberites
''Arthaberites'' is a genus of ceratitid cephalopods included in the Noritidae The Noritidae, sometimes spelled Noritidea, is an extinct cephalopod family of belonging to the ammonoid order Ceratitida and superfamily Noritoidea Noritoidea, formerly Noritaceae, is an extinct superfamily of cephalopods belonging to the Am ... that lived during the Middle Triassic, found in the Alps and Balkans of Europe. Its type is ''A. alexandrae''. ''Arthaberites'' has an involute, compressed, discoidal shell with a narrow flatted venter, or outer rim. References * Arkell et al., 1957. Mesozoic Ammonoidea.

Noritidae
The Noritidae, sometimes spelled Noritidea, is an extinct cephalopod family of belonging to the ammonoid order Ceratitida and superfamily Noritoidea. The Noritidae, which lived during the Early and Middle Triassic, are characterized by smooth, flat, discoidal shells with tabulate venters bordered by pronounced shoulders. Sutures are ceratitic with club-shaped saddles.

Triassic
The Triassic ( ) is a geologic period and system (stratigraphy), system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago (Year#Abbreviations yr and ya, Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic, Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Diener
Carl Diener (11 December 1862 in Vienna – 6 January 1928, Vienna) was an Austrian geographer, geologist and paleontologist. Biography In 1883 he received his doctorate from the University of Vienna, where his instructors included Eduard Suess and Melchior Neumayr. In 1893 he changed his venia legendi from geography to geology, a subject that he became an associate professor of in 1897. In 1906 he was named a full professor of paleontology at the University of Vienna.Diener, Carl Deutsche Biographie He is best remembered for his geological (including stratigraphic) and faunistic investigations of the . He also conducted important res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceratitida
Ceratitida is an order that contains almost all ammonoid cephalopod genera from the Triassic as well as ancestral forms from the Upper Permian, the exception being the phylloceratids which gave rise to the great diversity of post Triassic ammonites. Ceratitids overwhelmingly produced planospirally coiled discoidal shells that may be evolute with inner whorls exposed or involute with only the outer whorl showing. In a few later forms the shell became subglobular, in others, trochoidal or uncoiled. Sutures are typically ceratitic, with smooth saddles and serrate or digitized lobes. In a few the sutures are goniatitic while in others they are ammonitic.
