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.

List Of Ammonite Genera
This list of ammonites is a comprehensive listing of genera that are included in the subclass †Ammonoidea, excluding purely vernacular terms. The list includes genera that are commonly accepted as valid, as well those that may be invalid or doubtful (''nomina dubia''), or were not formally published (''nomina nuda''), as well as junior synonyms of more established names, and genera that are no longer considered ammonites. __NOTOC__ Reliability of this list Most of the generic names in this list come from Jack Sepkoski's 2002 compendium of marine fossil genera, which can be corroborated by other sources such as Part L, Ammonoidea, in the Treatise on Invertebrate Paleontology. Additional generic names included come from the Treatise or various peer review scientific journals. 150px, Ammolite is an iridescent gem stone">iridescent.html" ;"title="Ammolite is an iridescent">Ammolite is an iridescent gem stone made from the shells of fossil ammonites A file:Arcestes.jpg, 150px, The ...

Abritus
Abritus (Abrittus) was an impressive Roman walled city and one of the biggest urban centres in the province of Moesia Inferior. Its remains are in the Archaeological Park of Razgrad. History A Thracian settlement of the 3rd–4th century BC has been found on the north bank of the Beli Lom river, and an early Roman settlement extended it in the late 1st or early 2nd century AD. At the end of the 1st century AD a Roman military camp was built, and in the 2nd century the Cohors II Lucensium of the Legio XI Claudia (based at Durostorum) was stationed here. In 251 during the Gothic invasions the Romans suffered a disastrous defeat and the death of the Emperor Decius and his son Herennius Etruscus at the Battle of Abritus, which took place about northwest of Abritus, in the valley of the river Beli Lom, to the south of the village of Dryanovets.

Hauterivian
The Hauterivian is, in the geologic timescale, an age in the Early Cretaceous Epoch or a stage in the Lower Cretaceous Series. It spans the time between 132.9 ± 2 Ma and 129.4 ± 1.5 Ma (million years ago). The Hauterivian is preceded by the Valanginian and succeeded by the Barremian.See Gradstein ''et al.'' (2004) for a detailed geologic timescale Stratigraphic definitions The Hauterivian was introduced in scientific literature by Swiss geologist Eugène Renevier in 1873. It is named after the Swiss town of Hauterive at the shore of Lake Neuchâtel. The base of the Hauterivian is defined as the place in the stratigraphic column where the ammonite genus ''Acanthodiscus'' first appears. A reference profile for the base (a GSSP) was officially ratified by the International Union of Geological Sciences in December of 2019, and is placed in La Charce, France. The top of the Hauterivian (the base of the Barremian) is at the first appearance of ammonite species ''Spitidiscus hugii'' ...

Barremian
The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 129.4 ± 1.5 Ma (million years ago) and 121.4 ± 1.0 Ma). It is a subdivision of the Early Cretaceous Epoch (or Lower Cretaceous Series). It is preceded by the Hauterivian and followed by the Aptian Stage.See Gradstein ''et al.'' (2004) or the online geowhen database (link below) Stratigraphic definitions The original type locality for the Barremian Stage is in the vicinity of the village of Barrême, Alpes-de-Haute-Provence, France. Henri Coquand defined the stage and named it in 1873. The base of the Barremian is determined by the first appearance of the ammonites ''Spitidiscus hugii'' and ''Spitidiscus vandeckii''. The end of the Barremian is determined by the geomagnetic reversal at the start of the M0r chronozone, which is biologically near the first appearance of the ammonite '' Paradeshayesites oglanlensis''.

Émile Haug
Gustave Émile Haug (19 June 1861 - 28 August 1927) was a French geologist and paleontologist known for his contribution to the geosyncline theory. Career Émile Haug was born on 19 June 1861. In 1884 he received his doctorate in natural sciences from the University of Strasbourg with a dissertation on the ammonite genus '' Harpoceras'', titled "''Beiträge zu einer monographie der Ammonitengattung Harpoceras''". In 1897 he became ''maître de conférences'' at the Sorbonne in Paris, where in 1904 he was named a full professor of geology.Haug, Gustave Émile Sociétés savantes de France In 1902 he was appointed president of the , and from 1917 to 19 ...

Stoycho Vassilev Breskovski
Stoycho Vassilev Breskovski ( bg, Стойчо Василев Бресковски) (December 25, 1934, Granit, Stara Zagora Province, Bulgaria – January 15, 2004, Sofia, Bulgaria) was a Bulgarian paleontologist. Biography Stoycho Breskovski was the only son of educators Vassil Stoychev Breskovski (1902 - 1978) and Paraskeva () Breskovska (1906 - 1988). After receiving his primary and secondary education in Plovdiv, he studied geology at Sofia University and graduated in 1958. Then, he took active part in Bulgarian geological survey and in the preparation of the geologic map of Bulgaria at scale of 1:200,000. Later Dr. Breskovski was noted for his research on Lower Cretaceous, Barremian fauna. He was also credited for discovering, identifying and discerning several families, subfamilies, genera and species of ammonites. From 1974 to 1995 Breskovski had been research associate and curator of the paleontology collection at the National Museum of Natural History in Sofia. He ...

Ammonoidea
Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) than they are to shelled nautiloids such as the living ''Nautilus'' species. The earliest ammonites appeared during the Devonian, with the last species vanishing during the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and linking the rock layer in which a particular species or genus is found to specific geologic time periods is often possible. Their fossil shells usually take the form of planispirals, although some helically spiraled and nonspiraled forms (known as heteromorphs) have been found. The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns.

Razgrad
Razgrad ( bg, Разград ) is a city in Northeastern Bulgaria in the valley of the Beli Lom river that falls within the historical and geographical region of Ludogorie (Deliorman). It is an administrative center of Razgrad Province. Etymology The suffix "grad" means city in Bulgarian, while the origin and the meaning of the first part "raz" is obscure. During the Second Bulgarian Empire, around the present city there was a settlement, mentioned by the names of ''Hrasgrad'', ''Hrazgrad'' and ''Hrizgrad. These names come from the name of the Bulgar and Slavic god Hors. History Razgrad was built upon the ruins of the Ancient Roman town of Abritus on the banks of the Beli Lom river. Abritus was built on a Thracian settlement of the 4th-5th century BC of unknown name. Several bronze coins of the Thracian king Seuthes III (330-300 BC) and pottery were found, as well as artifacts from other rulers and a sacrificial altar of Hercules. Some of Razgrad's landmarks include the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
