Alligatorellus
''Alligatorellus'' is an extinct genus of Atoposauridae, atoposaurid crocodyliform found in France that was related to ''Atoposaurus''. A skeleton of ''Alligatorellus'' has also been found in the Solnhofen Limestone of Kelheim, Germany. The limestone was deposited in a marine environment and the individual may have washed into a lagoon where it was fossilized. Remains of four crinoids that lived in the lagoon are found in the same block as the skeleton. The skeleton includes osteoderms and limb bones, which are three-dimensionally preserved. The German skeleton shows more details of atoposaurid anatomy than most fossils, as other atoposaurid remains are compressed flat.

Atoposauridae
Atoposauridae is a Family (biology), family of crocodile-line archosaurs belonging to Neosuchia. The majority of the family are known from Late Jurassic to Early Cretaceous marine deposits in France, Portugal, and Bavaria in southern Germany. The discovery of the genus ''Aprosuchus'', however, extends the duration of the lineage to the end of the Cretaceous in Romania.

Atoposaurus
''Atoposaurus'' is an extinct genus of crocodylomorph. It is the type genus of the family Atoposauridae. Fossils have been found that were Late Jurassic in age from two distinct species in France and Germany. One interesting feature of ''Atoposaurus'' is that it lacked dorsal scutes, a common characteristic of atoposaurids as well as most crurotarsans. The absence of scutes, along with its relatively small size (specimens reach lengths of up to 17 cm), narrow supratemporal fossae, wide occipital region, thin postorbital bar, and smooth ornamentation, has led some paleontologists to believe that it is perhaps a juvenile form of another genus within Atoposauridae, most likely ''Alligatorellus''. History of the holotype The Teylers Museum has a holotype specimen ''Atoposaurus oberndorfi'' that was bought by curator J.G.S. van Breda in 1863 from Adam August Krantz (1809-1872), dealer in minerals in Bonn from 1850 onwards. The purchase was made along with the other holotypes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Osteoderm
Osteoderms are bony deposits forming scales, plates, or other structures based in the dermis. Osteoderms are found in many groups of extant and extinct reptiles and amphibians, including lizards, crocodilians, frogs, temnospondyls (extinct amphibians), various groups of dinosaurs (most notably ankylosaurs and stegosaurians), phytosaurs, aetosaurs, placodonts, and hupehsuchians (marine reptiles with possible ichthyosaur affinities). Osteoderms are uncommon in mammals, although they have occurred in many xenarthrans (armadillos and the extinct glyptodonts and mylodontid and scelidotheriid ground sloths). The heavy, bony osteoderms have evolved independently in many different lineages. The armadillo osteoderm is believed to develop in subcutaneous dermal tissues. These varied structures should be thought of as anatomical analogues, not homologues, and do not necessarily indicate monophyly. The structures are however derived from scutes, common to all classes of amniotes and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crinoid
Crinoids are marine animals that make up the class Crinoidea. Crinoids that are attached to the sea bottom by a stalk in their adult form are commonly called sea lilies, while the unstalked forms are called feather stars or comatulids, which are members of the largest crinoid order, Comatulida. Crinoids are echinoderms in the phylum Echinodermata, which also includes the starfish, brittle stars, sea urchins and sea cucumbers. They live in both shallow water and in depths as great as . Adult crinoids are characterised by having the mouth located on the upper surface. This is surrounded by feeding arms, and is linked to a U-shaped gut, with the anus being located on the oral disc near the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, in most crinoids the five arms are subdivided into ten or more. These have feathery pinnules and are spread wide to gather planktonic particles from the water. At some stage in their lives, most crinoids have ...

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kelheim
Kelheim () is a town and municipality in Bavaria, Germany. It is the capital of the district Kelheim and is situated at the confluence of the rivers Altmühl and Danube. Kelheim has a population of around 16,750 (2020). History Kelheim is the site of a large Iron Age oppidum from the La Tène period, which has been tentatively identified with the Celtic city of Alcimoennis mentioned by Ptolemy in his ''Geography''. The ramparts of the fort cross the promontory between the rivers Altmühl and Danube. There is an inner defensive line enclosing 60 ha near the confluence, then a long outer rampart enclosing an enormous area of 630 ha. A small promontory fort on the other bank of the Danube has a series of short linear ramparts protecting a settlement in the bend of a meander. This is aligned with the end of the outer rampart on the far bank, dominating traffic on the river. Kelheim has given its name to the ''pfostenschlitzmauer'' style of rampart construction characterized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow.
