Boii (genus)
''Boii'' is an extinct genus of microsaur within the family Tuditanidae. It was found in Carboniferous coal from mines near the community of Kounov in the Czech Republic. The only remains of the genus consist of a crushed skull, shoulder girdle bones, and scales, which were similar to microsaurian elements originally referred to ''Asaphestera''. ''Boii'' can be characterized by its heavily sculptured skull, thin ventral plate of the clavicles, and a larger number of fangs on the roof of the mouth. For many years the type and only known species, ''Boii crassidens'', was considered to be a species of ''Sparodus'', until 1966 when Robert Carroll assigned it to its own genus. History The specimen now designated as ''Boii crassidens'' was first described by Antonin Frič, one of the most notable paleontologists in the late 19th century region of Bohemia (now part of the Czech Republic). Frič made many contributions to knowledge of Carboniferous tetrapods during his lifetime, inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian line ...

Branchiosaurus
''Branchiosaurus'' (from el, βράγχιον , 'gill' and el, σαῦρος , 'lizard') is a genus of small, lightly built early prehistoric amphibians. Fossils have been discovered in strata dating from the late Pennsylvanian Epoch to the Permian Period. The taxa may be invalid; the material referred to the genus may be juvenile specimens of larger amphibians. This tiny amphibian was very similar to the Rachitomi, differing primarily in size. Other distinguishing characteristics include a cartilaginous, less ossified skeleton and a shorter skull. Clear traces of gills are present in many fossilized samples, hence the name. Originally thought to have vertebrae distinct from rachitomous vertebrae, it was placed in a separate order named Phyllospondyli ("leaf vertebrae"). Later analysis of growth stages showed increasing ossification in larger specimens, which showed that at least some of the species was the larval stage of much larger rachitomes like ''Eryops'', while o ...

Roman Republic
The Roman Republic ( la, Res publica Romana ) was a form of government of Rome and the era of the classical Roman civilization when it was run through public representation of the Roman people. Beginning with the overthrow of the Roman Kingdom (traditionally dated to 509 BC) and ending in 27 BC with the establishment of the Roman Empire, Rome's control rapidly expanded during this period—from the city's immediate surroundings to hegemony over the entire Mediterranean world. Roman society under the Republic was primarily a cultural mix of Latin and Etruscan societies, as well as of Sabine, Oscan, and Greek cultural elements, which is especially visible in the Roman Pantheon. Its political organization developed, at around the same time as direct democracy in Ancient Greece, with collective and annual magistracies, overseen by a senate. The top magistrates were the two consuls, who had an extensive range of executive, legislative, judicial, military, and religious powers ...

Boii
The Boii (Latin plural, singular ''Boius''; grc, Βόιοι) were a Celtic tribe of the later Iron Age, attested at various times in Cisalpine Gaul (Northern Italy), Pannonia (Hungary), parts of Bavaria, in and around Bohemia (after whom the region is named in most languages; comprising the bulk of today's Czech Republic), parts of Poland, and Gallia Narbonensis (located in modern Languedoc and Provence). In addition, the archaeological evidence indicates that in the 2nd century BC Celts expanded from Bohemia through the Kłodzko Valley into Silesia, now part of Poland and the Czech Republic. They first appear in history in connection with the Gallic invasion of northern Italy, 390 BC, when they made the Etruscan city of Felsina their new capital, Bononia (Bologna). After a series of wars they were decisively beaten by the Romans in the Battle of Mutina (193 BC) and their territory became part of the Roman province of Cisalpine Gaul. According to Strabo, writing two c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maxilla
The maxilla (plural: ''maxillae'' ) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis. The mandible is the movable part of the jaw. Structure In humans, the maxilla consists of: * The body of the maxilla * Four processes ** the zygomatic process ** the frontal process of maxilla ** the alveolar process ** the palatine process * three surfaces – anterior, posterior, medial * the Infraorbital foramen * the maxillary sinus * the incisive foramen Articulations Each maxilla articulates with nine bones: * two of the cranium: the frontal and ethmoid * seven of the face: the nasal, zygomatic, lacrimal, inferior n ...

Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus ''Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Compression Fossil
A compression fossil is a fossil preserved in sedimentary rock that has undergone physical compression. While it is uncommon to find animals preserved as good compression fossils, it is very common to find plants preserved this way. The reason for this is that physical compression of the rock often leads to distortion of the fossil. The best fossils of leaves are found preserved in fine layers of sediment that have been compressed in a direction perpendicular to the plane of the deposited sediment. Since leaves are basically flat, the resulting distortion is minimal. Plant stems and other three-dimensional plant structures do not preserve as well under compression. Typically, only the basic outline and surface features are preserved in compression fossils; internal anatomy is not preserved. These fossils may be studied while still partially entombed in the sedimentary rock matrix where they are preserved, or once lifted out of the matrix by a peel or transfer technique. Compr ...
