Stenorhynchosaurus
''Stenorhynchosaurus'' is an extinct genus of pliosaurid plesiosaurs which lived in the Early Cretaceous of South America. The type species and only known is ''Stenorhynchosaurus munozi''. It was a medium-sized pliosaur, reaching an adult body length of . Discovery and naming Fossils from the front of a snout of a plesiosaur were discovered in 2000 on the property of Jorge Muñoz, in Loma La Cabrera, near Villa de Leyva in Boyacá, Colombia, on grounds of marine origin dating from the Late Barremian epoch of the Cretaceous. Muñoz reported the find to the local authorities, who in turn gave notice to staff of the Museo Geológico José Royo y Gómez administered by the Servicio Geológico Colombiano in Bogotá. Then was made the excavation of the nearly complete skeleton between 2004 and 2005, in collaboration with the Fundación Colombiana de Geobiología ("Colombian Geobiology Foundation"), and the remains being then transferred to Bogotá, assigning the catalog number VL ...

Fernando Etayo
Fernando Etayo Serna is a Colombian paleontologist and geologist. His contributions on the paleontology in Colombia has been mainly on the descriptions of ammonites and Etayo has helped describing many fossiliferous geologic formations of Colombia. Etayo obtained his MSc. degree in geology and geophysics from the Universidad Nacional de Colombia in 1963, and his PhD in paleontology from the University of California, Berkeley in 1975. Biography In 1962, Etayo Serna published his first work about the species '' Codakia orbicularis'' and '' Codakia orbiculata''. He has defined many geologic formations of Colombia in the 1960s and 1970s. Etayo, together with fellow paleontologist María Páramo, collaborated in describing the first dinosaur fossil found in Colombia, '' Padillasaurus'' from the Paja Formation, close to Villa de Leyva, Boyacá.Carballido et al., 2015 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachauchenius
''Brachauchenius'' (meaning 'short neck') is an extinct genus of pliosaurid that lived in North America (United States) and Morocco during the Late Cretaceous. History The type species, ''Brachauchenius lucasi'', lived in the Western Inland Sea of North America around 100.5-89.3 million years ago, from the Cenomonian to the Turonian of the Cretaceous. An older specimen from the Barremian of Colombia was considered as part of this genus, representing the first re-occurrence of the non-rhomaleosaurid pliosaurs after a Berriasian-Hauterivian hiatus.Hampe O. 2005. Considerations on a ''Brachauchenius'' skeleton (Pliosauroidea) from the lower Paja Formation (late Barremian) of Villa de Leyva area (Colombia). ''Fossil Record - Mitteilungen aus dem Museum für Naturkunde in Berlin'' 8 (1): 37-51. However, subsequent analysis of this Colombian specimen shows that it was enough distinctive to warrant a new genus and species, named as '' Stenorhynchosaurus munozi''. The first kno ...

Villa De Leyva
Villa de Leyva, also called Villa de Leiva, is a touristic colonial town and municipality, in the Ricaurte Province, part of the Boyacá Department of Colombia. The town is a Colombian National Heritage Town and is on the tentative list for UNESCO World Heritage Sites. Villa de Leyva is located west of the departmental capital Tunja. It is about three hours by car or bus from Bogotá. Located away from major trade routes in a high altitude valley of semi-desert terrain, and with no mineral deposits nearby to exploit, the town has undergone little development in the last 400 years. As a consequence, it is one of the few towns in Colombia to have preserved much of its original colonial style and architecture: the streets and large central plaza are still paved with cobblestones, and many buildings date from the sixteenth century. This has resulted in Villa de Leyva becoming one of Colombia's principal tourist attractions, and it was declared a National Monument on December 17, 19 ...

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''.

Fossils Of Colombia
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 absol ...

Cretaceous Colombia
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 mya (unit), million years ago (Mya). It is the third and final period of the Mesozoic Era (geology), Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin wikt:creta#Latin, ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high Sea level#Local and eustatic, eustatic sea levels that created numerous shallow Inland sea (geology), inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeare ...

Sauropterygian Genera
Sauropterygia ("lizard flippers") is an extinct taxon of diverse, aquatic reptiles that developed from terrestrial ancestors soon after the end-Permian extinction and flourished during the Triassic before all except for the Plesiosauria became extinct at the end of that period. The plesiosaurs would continue to diversify until the end of the Mesozoic. Sauropterygians are united by a radical adaptation of their pectoral girdle, adapted to support powerful flipper strokes. Some later sauropterygians, such as the pliosaurs, developed a similar mechanism in their pelvis. Uniquely among reptiles, sauropterygians moved their tail vertically like modern cetaceans and sirenians. Origins and evolution The earliest sauropterygians appeared about 247 million years ago (Ma), at the start of the Middle Triassic: the first definite sauropterygian with exact stratigraphic datum lies within the Spathian division of the Olenekian era in South China. Early examples were small (around 60 cm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
