Puzosia
''Puzosia'' is a genus of desmoceratid ammonites, and the type genus for the Puzosiinae, which lived during the middle part of the Cretaceous, from early Aptian to Maastrichtian (125.5 to 70.6 Ma). The generic name comes from the Serbian words "Puž" (snail) and "oce/ose" (axis), gaining its name from the shell's snail-like appearance.

Beudanticeras
''Beudanticeras'' is an extinct cephalopod genus from the Late Cretaceous period; Albian and Cenomanian, belonging to the ammonoid subclass and included in the family Desmoceratidae. ''Beudanticeras'' has a rather to very compressed shell that is moderately involute, with convex to flat sides and a narrowly arched out rim. Coiling is such that the outer whorl embraces much of the next inner whorl, leaving a small spiraled umbilicus. The shell is generally smooth but may have weak ribs but no tubercles. The suture is ammonitic. The derivation of ''Beudanticeras'' may be from ''Uhligella'', although ''Uhligella'' is partly contemporary with early ''Beudanticeras''. Other related genera include ''Beudantiella'', '' Brewericeras'', ''Zurcherella'', and possibly '' Pseudosaynella''.

Abrytasites
''Abrytasites'' (''Abrytusites'') is an extinct genus of cephalopods belonging to the Ammonoidea subclass. The genus was named after the ancient Roman town of Abrittus, located near the present Bulgarian city of Razgrad. There are several described species of ''Abrytasites'', including A. ''thieuloyi'', A. ''julianyi'', and A. ''neumayri''. They are inflated, with constrictions, have rather thick ribs springing irregularly, singly or in pairs, from umbilical bullae. Their inner whorls closely resemble types species of ''Valdedorsella''. with and (1996), ''Mollusca 4 Revised , Cretaceous Ammonoidea'', vol. 4, in ''Treatise on Invertebrate Paleontology'', Part L (Roger L.

Parapuzosia
''Parapuzosia'' is an extinct genus of desmoceratid ammonites from the Cenomanian to the Campanian The Campanian is the fifth of six ages of the Late Cretaceous Epoch on the geologic timescale of the International Commission on Stratigraphy (ICS). In chronostratigraphy, it is the fifth of six stages in the Upper Cretaceous Series. Campani ... of Africa, Europe, and North America. They are typically very large ammonites, reaching diameters of or more, with the largest species measuring upwards of more than . It possesses a moderately involute shell with flat or slightly rounded sides. Distinct primary and secondary ribbing can be observed in the inner whorls. Etymology The origin of the generic name ''Parapuzosia'' ("similar to '' Puzosia''") comes from the smaller, related desmatoceratid '' Puzosia''. "Puzosia" comes from the Serbian words "пужа/Puzo" (Snail) and "Oca/Osia" (Axis), translating to "snail axis". References Desmoceratidae Ammonitida genera ...

Karl Alfred Von Zittel
Karl Alfred Ritter von Zittel (25 September 1839 – 5 January 1904) was a German palaeontologist best known for his ''Handbuch der Palaeontologie'' (1876–1880). Biography Karl Alfred von Zittel was born in Bahlingen in the Grand Duchy of Baden. His father, Karl was a leading liberal cleric in Baden. He was educated at the University of Heidelberg, the University of Paris and the University of Vienna. For a short period he served on the Geological Survey of Austria, and as assistant in the mineralogical museum at Vienna. In 1863, he became teacher of geology and mineralogy in the polytechnic at Karlsruhe, and three years later he succeeded Albert Oppel as professor of palaeontology in the University of Munich, with the charge of the state collection of fossils. In 1880, he was appointed to the geological professorship, and eventually to the directorship of the natural history museum of Munich. His earlier work comprised a monograph on the ''Cretaceous bivalve mollusca of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuttlefish
Cuttlefish or cuttles are marine molluscs of the order Sepiida. They belong to the class Cephalopoda which also includes squid, octopuses, and nautiluses. Cuttlefish have a unique internal shell, the cuttlebone, which is used for control of buoyancy. Cuttlefish have large, W-shaped pupils, eight arms, and two tentacles furnished with denticulated suckers, with which they secure their prey. They generally range in size from , with the largest species, the giant cuttlefish (''Sepia apama''), reaching in mantle length and over in mass. Cuttlefish eat small molluscs, crabs, shrimp, fish, octopus, worms, and other cuttlefish. Their predators include dolphins, sharks, fish, seals, seabirds, and other cuttlefish. The typical life expectancy of a cuttlefish is about 1–2 years. Studies are said to indicate cuttlefish to be among the most intelligent invertebrates.

Nautiloid
Nautiloids are a group of marine cephalopods ( Mollusca) which originated in the Late Cambrian and are represented today by the living ''Nautilus'' and ''Allonautilus''. Fossil nautiloids are diverse and speciose, with over 2,500 recorded species. They flourished during the early Paleozoic era, when they constituted the main predatory animals. Early in their evolution, nautiloids developed an extraordinary diversity of shell shapes, including coiled morphologies and giant straight-shelled forms ( orthocones). Only a handful of rare coiled species, the nautiluses, survive to the present day. In a broad sense, "nautiloid" refers to a major cephalopod subclass or collection of subclasses (Nautiloidea ''sensu lato''). Nautiloids are typically considered one of three main groups of cephalopods, along with the extinct ammonoids (ammonites) and living coleoids (such as squid, octopus, and kin). While ammonoids and coleoids are monophyletic clades with exclusive ancestor-descendant rel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
