Colombia no solo es un país rico en ecosistemas naturales, fauna y flora, sino que somos también un país geodiverso y fascinante. Las múltiples configuraciones que han tomado nuestros suelos y subsuelos determinan la manera en que transcurre nuestra vida aquí, en la superficie, sobre montañas, volcanes, llanuras, sabanas y desiertos: todas estas va...

Six vertebrae (one cervical, three articulated thoracic, and two lumbar) and an incomplete thoracic neural spine from a new late Pleistocene site at Anolaima, Cundinamarca, Colombia, are attributed to the extinct gomphothere (Elephantoidea, Proboscidea) Notiomastodon platensis . The preserved bones exhibit a range of alterations, including porositi...

Kronosaurus boyacensis is the most famous and most important Lower Cretaceous marine reptile fossil recovered from the Villa de Leyva region of Boyacá, Colombia, northern South America. To the local population it has become iconic as The Fossil (‘El Fósil’) of Colombia. Here we provide a detailed re-description of the holotype of the pliosaurid sau...

The attribution of osteological remains of a bird discovered in Preceramic deposits at Nemocón IV rockshelter (Sabana de Bogotá, Colombia) to Ara sp. (macaws) is confirmed through osteological and morphometrical analyses. Thirteen bones were recovered from two adjacent, arbitrary excavation levels; and are considered the remains of a single individ...

The Geology of Colombia book provides an updated background of the geological knowledge of Colombia by integrating the most up–to–date research covering paleontology, biostratigraphy, sedimentary basin analysis, sedimentology, sequence stratigraphy, stratigraphy, geophysics, geochronology, geochemistry, thermochronology, tectonics, structure, volca...

The Cretaceous Paja Formation of the alto Ricaurte of the Eastern Cordillera of central Colombia was laid down under an epicontinental sea during Hauterivian – Aptian times. The Paja Formation epicontinental sea was home to a diverse, and now well–preserved, pelagic marine fauna that includes members of Plesiosauria, other marine reptiles, fish, an...

Dinosaur remains from northwestern South America are rare, with only extremely scarce fossil evidence recovered from Colombia. Here we report six dinosaur footprints preserved on a sub–vertical bedding plane of the upper Valanginian – lower Hauterivian Batá Formation, Santa María, Boyacá Department, Colombia. The Batá Formation consists of a thick...

Chemical preparation is an important technique in palaeontology that uses a dilute aqueous acid solution to remove calcareous matrix from fossils, but which leads to the evolution of salts as a by-product. Acid preparation is usually undertaken using formic and acetic acids, whereas sulphamic acid has only rarely been considered. Sulphamic acid is...

Temporally available at: https://authors.elsevier.com/a/1ZHtl3qItyaTp Mary Anning, Alfred Nicholson Leeds and Steve Etches form part of a long line of individuals who furnished a substantial addition to our understanding of marine and terrestrial ecosystems through collecting significant numbers of superb fossils. For all three collectors, fossils...

A collaboration between geoscience professors and pedagogic and technical support experts at Universidad de los Andes led to a teaching innovation, as part of a project entitled GEOC-SENSE. GEOC-SENSE was based on the use of active pedagogy techniques aided by information and communication technologies (ICT) to improve motivation and acquisition of...

Videos about the geology and palaeontology of the Alto Ricaurte region of central Colombia in advance of publication of the Geology of Colombia book.

Following the marine extinctions at the end of the Jurassic, only three clades of Plesiosauria passed into the Lower Cretaceous: Brachaucheninae (thalassophonean pliosaurids), Cryptoclididae, and Xenopsaria. However, these plesiosaur clades, and the Brachaucheninae in particular, are represented by a limited number of genera. The Berriasian to Albi...

The need for this innovation stems from the constraints of teaching an applied science course to a large cohort of approximately 500 students which makes it impossible to include practical activities. This was compounded by the fact that the course had students with different levels of science knowledge. The aim of our pedagogic innovation was two-...

The evolution and function of the long neck in plesiosaurs, and how the problems associated with stiffness or flexibility were overcome during feeding, or rapid swimming during predator avoidance, are explored, and a new interpretation for the function of the plesiosaur neck is presented. Based on the anatomy of the articular faces of contiguous ce...

Resumen From one of the most complete Lower Cretaceous rock sequences in the world (in Villa de Leiva region, central Colombia), we describe a new genus and species of pliosaurid plesiosaur Stenorhynchosaurus munozi. Stenorhynchosaurus displays a series of features which differentiate it from all the other Cretaceous pliosaurid genera: the anterio...

Complete skulls of giant marine reptiles of the Late Jurassic are rare, and so the discovery of the 1.8‐m‐long skull of a pliosaur from the Kimmeridge Clay Formation (Kimmeridgian) of Westbury, Wiltshire, UK, is an important find. The specimen shows most of the cranial and mandibular anatomy, as well as a series of pathological conditions. It was p...

  An almost complete, three-dimensionally preserved plesiosaurian from the Hildoceras bifrons Zone of the Alum Shale Member (Whitby Limestone Formation; Lower Toarcian) of Yorkshire, UK, is described in detail. This represents a new species of Hauffiosaurus, H. tomistomimus, distinguished from H. zanoni (Harpoceras serpentinum Zone, Lower Toarcian,...

Alfred Nicholson Leeds, F.G.S., amassed one of the largest collections of fossil vertebrates from a single geological horizon anywhere in the world. The Leeds Collection is world famous for its large marine reptiles, but also includes the remains of a fine range of dinosaurs and a fragmentary pterosaur. The Leeds Collection ornithodirans were almos...

Acid preparation of large vertebrate fossils poses special problems for the preparator. The Fundación Colombiana de Geobiología has prepared a number of large vertebrates (marine reptiles from the Cretaceous of Colombia, South America) using acid to remove calcareous matrix. A combination of factors, including: specimen size: choice of acid; number...

The holotype is the single most important specimen in zoological taxonomy, and to avoid confusion, it must be the remains of a single individual. Re-evaluation of data presented to infer that three specimens collected between 1954 and 1998 are additional material of the holotype of Elasmosaurus platyurus, indicate there is no evidence these two set...

As a result of a collaborative research effort between the Universidad Nacional de Colombia and the Sedgwick Museum (UK) the acid prepared skull and rock encased postcranial skeleton of a new Cretaceous marine reptile (a pliosaur) has been transported from Bogot� to the University of Cambridge. This contribution details the procedure from agreeing...

  Duplication of previously published text or figures in the scientific literature without adequate citation is plagiarism or, in the case of an author's own work, self-plagiarism. It breaches the ethical standards that are expected in science and threatens the integrity of scientific journals. Three examples of duplication are noted, one of which...

The specimen of the tail of Leedsichthys problematicus, now in The Natural History Museum, London, was one of the most spectacular fossil vertebrates from the Oxford Clay Formation of Peterborough, but as an isolated find it shares no bones in common with the holotype of the genus and species. However, a letter from Alfred Nicholson Leeds and relat...

‘Tarlo's Contention’, that a mandible possessing five to six large caniniform teeth characterizes Pliosaurus macromerus is explored and shown to rest on the assumption that only two morphologies of pliosaur mandibular symphysis exist in the Kimmeridge Clay Formation. A new taxon, Pliosaurus portentificus sp. nov., is described based on a third mand...

Se describen los pimeros restos de reptiles marinos de Aptiense inferior de Morella (Castellón). Todos los ejemplares son asignados al taxón Plesiosauria y proceden de dos localidades distintas. Uno de los conjuntos de material ha sido recogido en un único nivel de la Cantera. Más de la Parreta (CMP3). Esta localidad ha proporcionado una docena de...

A new and unusual pliosaurid from the Peterborough Member, Oxford Clay Formation (Callovian, Jurassic) of Cambridgeshire, UK, exhibits a type of pachyostosis and bone thickening of the rib cage and vertebrae. Pachycostasaurus dawni gen. et sp. nov. was most probably a benthic feeding carnivore with a generalist diet that included fish and invertebr...
