Villalba De La Sierra Formation
The Villalba de la Sierra Formation is a Campanian to Maastrichtian geologic formation in Spain. Fossil dinosaur eggs have been reported from the formation, that comprises gypsiferous, grey, argillaceous mudstones and sandstones, deposited in a floodplain environmentWeishampel et al., 2004, pp.517-607 characterised by high seasonality and variability in water availability. Fossil content The formation has provided abundant titanosaurian remains, including '' Lohuecotitan'' were found in the formation.Díez Díaz et al., 2016 More than 10,000 fossil remains of various fishes, amphibians, lizards, dinosaurs ('' Ampelosaurus sp.'', '' Rhabdodon sp.''), turtles ('' Foxemys mechinorum'', '' Iberoccitanemys convenarum''), and crocodiles ('' Lohuecosuchus megadontos'', '' Agaresuchus fontisensis'', '' Musturzabalsuchus sp.'') are also known from the site, one of the richest for the Late Cretaceous in Europe.Ortega et al., 2015 See also * List of dinosaur-bearing rock formations ** L ...

Titanosaur
Titanosaurs (or titanosaurians; members of the group Titanosauria) were a diverse group of sauropod dinosaurs, including genera from all seven continents. The titanosaurs were the last surviving group of long-necked sauropods, with taxa still thriving at the time of the extinction event at the end of the Cretaceous. This group includes some of the largest land animals known to have ever existed, such as ''Patagotitan''—estimated at long with a weight of —and the comparably-sized ''Argentinosaurus'' and ''Puertasaurus'' from the same region. The group's name alludes to the mythological Titans of ancient Greek mythology, via the type genus (now considered a '' nomen dubium)'' ''Titanosaurus''. Together with the brachiosaurids and relatives, titanosaurs make up the larger sauropod clade Titanosauriformes. Titanosaurs have long been a poorly-known group, and the relationships between titanosaur species are still not well-understood. Description Titanosauria have the largest ...

Depositional Environment
In geology, depositional environment or sedimentary environment describes the combination of physical, chemical, and biological processes associated with the deposition of a particular type of sediment and, therefore, the rock types that will be formed after lithification, if the sediment is preserved in the rock record. In most cases, the environments associated with particular rock types or associations of rock types can be matched to existing analogues. However, the further back in geological time sediments were deposited, the more likely that direct modern analogues are not available (e.g. banded iron formations). Types of depositional environments Continental * – type of Fluvial deposit. Caused by moving water in a fan shape (Alluvial Fan) and containing mostly impermeable and nonporous sediments well sorted. * . Often in deserts and coastal regions and well sorted, large scale cross-beds * – processes due to moving water, mainly streams. Common sediments are grav ...

Musturzabalsuchus
''Musturzabalsuchus'' is an extinct monospecific genus of allodaposuchid eusuchian crocodyliform. The type and only species is ''Musturzabalsuchus buffetauti''. Etymology The generic name means "broadened rostrum crocodile", with "Musturzabal" meaning "broadened rostrum" in Basque and "suchus" meaning "crocodile" in Greek. The type and only species is ''M. buffetauti'', named after the French paleoherpetologist Eric Buffetaut. Discovery The material first assigned to ''Musturzabalsuchus'' in 1997 has been found from the locality of Laño in Condado de Treviño, northern Spain. Although dating back to the Late Cretaceous, the exact age of the strata in which material of ''Musturzabalsuchus'' occurs in the locality is not known: it is either Late Campanian or very Early Maastrichtian. Despite the unusually high quantity of remains belonging to the genus, the only skeletal elements known from ''Musturzabalsuchus'' are the maxilla and mandible. Some fragments of these bones have ...

Agaresuchus
''Agaresuchus'' is an extinct genus of allodaposuchid eusuchian crocodylomorph from the Late Cretaceous (Campanian-Maastrichtian) of Spain. It includes two species, the type species ''Agaresuchus fontisensis'', and ''Agaresuchus subjuniperus'', which was originally named as a species of the related genus ''Allodaposuchus''. However, it has been proposed that both species may instead belong to the genus ''Allodaposuchus''. Discovery and naming The genus ''Agaresuchus'' was named in 2016 upon the discovery of '' Agaresuchus fontisensis''. ''Allodaposuchus subjuniperus'', discovered in 2013 and originally classified as a new and second species of ''Allodaposuchus'', was then reassigned to ''Agaresuchus''. ''A. subjuniperus'' was named in 2013 on the basis of a skull from the late Maastrichtian-aged Conquès Formation, part of the Tremp Group, in the province of Huesca, Spain. The skull was found underneath a juniper tree whose roots had grown between the bones, hence the species n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lohuecosuchus
''Lohuecosuchus'' (meaning "Lo Hueco crocodile") is an extinct genus of Allodaposuchidae, allodaposuchid eusuchian Crocodylomorpha, crocodylomorph that lived during the Late Cretaceous (late Campanian to early Maastrichtian) in what is now Spain and southern France. Description The anatomy of the endocranium (braincase) of ''L. megadontos'' was found to be similar to crown-crocodylians, revealing that the acute sense of olfaction and low frequency hearing found in living crocodylians likely originated along the stem-line. Classification ''Lohuecosuchus'' is a member of the clade Allodaposuchidae, a group of eusuchians that lived in southern Europe during the Late Cretaceous. Two species of ''Lohuecosuchus'' were scientifically described, described in 2015. The type species, ''Lohuecosuchus megadontos'', was recovered from the Lo Hueco fossil site of the Villalba de la Sierra Formation in the municipality of Fuentes, Cuenca, Fuentes, Cuenca Province at Castilla-La Mancha of centr ...

Iberoccitanemys
''Iberoccitanemys'' (meaning "Iberoccitanian turtle") is an extinct genus of turtle from the Bothremydidae that is known from the Marnes d'Auzas Formation in France, and also the Sobrepena Formation and Villalba de la Sierra Formation in Spain. Discovery and naming Two species are known: ''I. convenarum'' (the type) and ''I. atlanticum'', which were both referred to other generade Lapparent de Broin, F. & Murelaga, X. (1996). Une nouvelle faune de chéloniens dans le crétacé supérieur européen. ''Comptes Rendus de l’Académie des Sciences'' 323: 729-735 before being moved to ''Iberoccitanemys''; the genus was named by Perez-Garcia, Ortega & Murelaga (2012).

Rhabdodon
''Rhabdodon'' (meaning "fluted tooth") is a genus of ornithopod dinosaur that lived in Europe approximately 70-66 million years ago in the Late Cretaceous. It is similar in build to a very robust "hypsilophodont" (non-iguanodont ornithopod), though all modern phylogenetic analyses find this to be an unnatural grouping, and ''Rhabdodon'' to be a basal member of Iguanodontia. It was large amongst its relatives, measuring long and weighing , with some specimens possibly reaching up to long. Discovery Two species of ''Rhabdodon'' are known, ''Rhabdodon priscus'', the type species, and ''R. septimanicus'' (Buffetaut and Le Loeuff, 1991). ''Rhabdodon'' remains are currently known from southern France, although fragmentary remains from eastern Spain have been assigned to the genus. ''Rhabdodon'' was large compared to its nearest relatives, and indeed one recent paper ( Ősi ''et al.'' (2012)) determined it is larger than the basal rhabdodontid status; from this they suggested that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ampelosaurus
''Ampelosaurus'' ( ; meaning "vine lizard") is a titanosaurian sauropod dinosaur from the Late Cretaceous Period of what is now France. Its type species is ''A. atacis'', named by Le Loeuff in 1995. A possible unnamed species has given ''Ampelosaurus'' an age reaching to the latest Cretaceous, from about 70 to 66 million years ago. Like most sauropods, it would have had a long neck and tail but it also carried armor in the form of osteoderms. Over 500 bones have been assigned to ''Ampelosaurus'' and all but the braincase (assigned to ''A.'' sp.) has been assigned to ''A. atacis''. They are assigned to the same species because all the differences in the limb proportions have been linked to individual variation. ''A. atacis'' is known from a few, well-preserved teeth and some cranial material. A right scapula was discovered associated with a coracoid. The blade of the scapula, contrary to most titanosaurs, is triangular. The blade narrows at one end instead of showing an expans ...
