Radiolites
''Radiolites'' is a genus of rudists in the family Radiolitidae. Fossil record These rudists lived in the Cretaceous from the upper Albian to the upper Maastrichtian ages (age range: 112.6 to 66.043 million years ago). The fossils were found in Albania, Austria, Bulgaria, Croatia, Cuba, the Czech Republic, Egypt, France, Germany, Greece, Hungary, Italy, Jamaica, Mexico, Oman, Pakistan, Peru, Portugal, Romania, Serbia and Montenegro, Slovenia, Spain, Switzerland, Tunisia, Turkey, Turkmenistan and United States The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America.

Rudists
Rudists are a group of extinct box-, tube- or ring-shaped marine heterodont bivalves belonging to the order Hippuritida that arose during the Late Jurassic and became so diverse during the Cretaceous that they were major reef-building organisms in the Tethys Ocean, until their complete extinction at the close of the Cretaceous. Shell description The Late Jurassic forms were elongate, with both valves being similarly shaped, often pipe or stake-shaped, while the reef-building forms of the Cretaceous had one valve that became a flat lid, with the other valve becoming an inverted spike-like cone. The size of these conical forms ranged widely from just a few centimeters to well over a meter in length. Their "classic" morphology consisted of a lower, roughly conical valve that was attached to the seafloor or to neighboring rudists, and a smaller upper valve that served as a kind of lid for the organism. The small upper valve could take a variety of interesting forms, including: a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jurassic
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassi ...

Favus (bivalve)
Favus (Latin for "honeycomb") or tinea favosa is the severe form of tinea capitis, a skin infectious disease caused by the dermatophyte fungus ''Trichophyton schoenleinii.'' Typically the species affects the scalp, but occasionally occurs as onychomycosis, tinea barbae, or tinea corporis. The word ''favid'' is more used than French word ''favus'', which is close to the Latin etymology. Presentation The uncomplicated appearance is that of a number of yellowish, circular, cup-shaped crusts (scutulum or shield) grouped in patches like a honeycomb, each crust about the size of a split pea, with a bundle of hair projecting in the center. These increase in size and become crusted over, so that the characteristic lesion can only be seen round the edge of the scab. A mousy odour is often present. Growth continues to take place for several months, when scab and scutulum go away, leaving a shining bare patch destitute of hair. The disease is essentially chronic, lasting from ten to twe ...
