Komlosaurus
''Komlosaurus'' ("Komlo lizard") is an ichnogenus of theropod dinosaur from the Early Jurassic of Baranya, Hungary. The type species, ''Komlosaurus carbonis'', was described by Kordos in 1983. The type remains come from the Mecsek Coal Formation, from the Middle Hettangian to the Early Sinemurian, and comprise several footprints. Description In the Hettangian/Sinemurian deposits of the Komló area (Mecsek Mountain, Hungary), footprints of Jurassic dinosaurs assigned to the ichnospecies ''K. carbonis'' are the only published palaeontological data of vertebrates in this region; however, several fossils of plants and pollen has been discovered there.Ősi, A., Pálfy, J., Makádi, L., Szentesi, Z., Gulyás, P., Rabi, M., Botfalvai, G. & Hips, K. (2011)Hettangian (Early Jurassic) Dinosaur Tracksites from the Mecsek Mountains, Hungary ''Ichnos'', 18(2), 79-94. The footprints, which form tracks, occur in several levels on bedding planes of fine-grained sediments. The largest occurre ...

Hettangian
The Hettangian is the earliest age and lowest stage of the Jurassic The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), 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 J ... Geological time scale, Period of the geologic timescale. It spans the time between 201.3 ± 0.2 annum, Ma and 199.3 ± 0.3 Ma (million years ago). The Hettangian follows the Rhaetian (part of the Triassic Period) and is followed by the Sinemurian. In European stratigraphy the Hettangian is a part of the time span in which the Lias Group, Lias was deposited. An example is the British Blue Lias, which has an upper Rhaetian to Sinemurian age. Another example is the lower Lias from the Northern Limestone Alps where well-preserved but very rare ammonites, including Alsatites, have been found.

Sinemurian Life
In the geologic timescale, the Sinemurian is an age and stage in the Early or Lower Jurassic Epoch or Series. It spans the time between 199.3 ± 2 Ma and 190.8 ± 1.5 Ma (million years ago). The Sinemurian is preceded by the Hettangian and is followed by the Pliensbachian. In Europe the Sinemurian age, together with the Hettangian age, saw the deposition of the lower Lias, in Great Britain known as the Blue Lias. Stratigraphic definitions The Sinemurian Stage was defined and introduced into scientific literature by French palaeontologist Alcide d'Orbigny in 1842. It takes its name from the French town of Semur-en-Auxois, near Dijon. The calcareous soil formed from the Jurassic limestone of the region is in part responsible for the character of the classic Sancerre wines. The base of the Sinemurian Stage is at the first appearance of the ammonite genera ''Vermiceras'' and '' Metophioceras'' in the stratigraphic record.

List Of Dinosaur Ichnogenera
This list of dinosaur ichnogenera is a comprehensive listing of all ichnogenera that have been attributed to dinosaurs, excluding class Aves (birds, both living and those known only from fossils) and purely vernacular terms. The list includes all commonly accepted ichnogenera, but also genera that are now considered invalid, doubtful (''nomen dubium''), or were not formally published (''nomen nudum''), as well as junior synonyms of more established names, and ichnogenera that are no longer attributed to dinosaurs. Scope and terminology There is no official, canonical list of dinosaur ichnogenera. An extensive list can be found in an appendix to Donald F. Glut's third supplement to his series of dinosaur encyclopedias (2003). The vast majority of citations are based on Glut's list; exceptions, such as more recent ichnotaxa, are noted. Synonymies are also after Glut. A B C D E F G H I J K L M N O __NOTOC__ P Q R S T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Komló
Komló (, german: Kumlau, hr, Komlov) is a town in Baranya county, Hungary. The name of the settlement is derived from the local crop of hops (komló), an ingredient of beer. By the 18th century a depiction of this plant running up a support already featured on the herald of the town. The former village of Komló became a planned mining city during the socialist era. It was the second biggest mining centre in Hungary after Tatabánya. History The area was inhabited by the Romans, the ruins of 2nd-century Roman villas were discovered during the laying of foundations for new buildings in the area (Mecsekjánosi, Körtvélyes). The existence of the once village is first mentioned in a charter from 1256 as 'villa Compleov', then part of the estates of the Pécsvárad Abbey. The small settlements that are part of Komló today were already inhabited during the Árpád Age (Kökönyös (Kwkenyes), Gadány-puszta (Gadan), Keményfalva (Kemefalua), Jánosi (Csépán), Mecsekfalu (Szop ...

Ornithopod
Ornithopoda () is a clade of ornithischian dinosaurs, called ornithopods (), that started out as small, bipedal running grazers and grew in size and numbers until they became one of the most successful groups of herbivores in the Cretaceous world, dominating the North American land. Their major evolutionary advantage was the progressive development of a chewing apparatus that became the most sophisticated ever developed by a non-avian dinosaur, rivaling that of modern mammals such as the domestic cow. They reached their apex of diversity and ecological dominance in the hadrosaurids (colloquially known as 'duck-bills'), before they were wiped out by the Cretaceous–Paleogene extinction event along with all other non-avian dinosaurs. Members are known from all seven continents, though they are generally rare in the Southern Hemisphere. History of research In 1870, Thomas Henry Huxley listed Iguanodontidae (coined by Cope a year earlier) as one of his three families of dinosaurs ( ...

Fossils Of Hungary
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Dinosaur Trace Fossils
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, are among th ...

Theropods
Theropoda (; ), whose members are known as theropods, is a dinosaur clade that is characterized by hollow bones and three toes and claws on each limb. Theropods are generally classed as a group of saurischian dinosaurs. They were ancestrally carnivorous, although a number of theropod groups evolved to become herbivores and omnivores. Theropods first appeared during the Carnian age of the late Triassic period 231.4 million years ago ( Ma) and included all the large terrestrial carnivores from the Early Jurassic until at least the close of the Cretaceous, about 66 Ma. In the Jurassic, birds evolved from small specialized coelurosaurian theropods, and are today represented by about 10,500 living species. Biology Diet and teeth Theropods exhibit a wide range of diets, from insectivores to herbivores and carnivores. Strict carnivory has always been considered the ancestral diet for theropods as a group, and a wider variety of diets was historically considered a characteri ...
