Lavocatia
''Lavocatia'' is a genus of extinct mammal from the Lower Cretaceous of Spain. It was a member of the also extinct order Multituberculata, and lived alongside of dinosaurs. Like most Mesozoic mammals, it was a shrewish-sized animal. It's in the suborder "Plagiaulacida" and family Pinheirodontidae. The genus ''Lavocatia'' was named by J. I. Canudo and G. Cuenca in 1996 based on a single tooth, with the generic epithet in honor of French paleontologist René Lavocat and the specific epithet a reference to the town of Alfambra. The species ''Lavocatia alfambrensis'' is known from the Barremian-age Camarillas Formation of Galve, Spain. This genus is apparently differentiated by the number of cusps on the tooth; 15. Also referred to in the reference is Peramura. This was a more "advanced" group of mammals, possibly ancestral to ourselves (see ''Peramus ''Peramus'' is an extinct genus of cladotherian mammal. It lived in the Late Jurassic and Early Cretaceous of Europe and North Af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camarillas Formation
The Camarillas Formation is a geological formation in the Teruel Province of Aragón, Spain whose strata date back to the Early Cretaceous ( Barremian stage). The sandstones, mudstones and conglomerates of the formation, that due to syn-sedimentary faulting varies greatly in thickness from , were deposited in fluvial, deltaic and lacustrine environments. The formation was deposited in the Galve Sub-basin of the Maestrazgo Basin in central-eastern Spain. During deposition, Iberia was an island, separated by seas from North Africa and France. Underlying the Camarillas Formation is the also highly fossiliferous El Castellar Formation and the Artoles Formation rests on top of the formation.Herrero Gascón & Pérez Lorente, 2009, p.68 The Camarillas Formation has provided a rich fossil assemblage of fossils of mammals, snakes, turtles, crocodylians, fish, dinosaurs and their eggs. Various tracksites of families of dinosaurs exist in the formation. Dinosaur remains ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multituberculata
Multituberculata (commonly known as multituberculates, named for the multiple tubercles of their teeth) is an extinct order of rodent-like mammals with a fossil record spanning over 130 million years. They first appeared in the Middle Jurassic, and reached a peak diversity during the Late Cretaceous and Paleocene. They eventually declined from the mid Paleocene onwards, disappearing from the known fossil record in the late Eocene. They are the most diverse order of Mesozoic mammals with more than 200 species known, ranging from mouse-sized to beaver-sized. These species occupied a diversity of ecological niches, ranging from burrow-dwelling to squirrel-like arborealism to jerboa-like hoppers. Multituberculates are usually placed as crown mammals outside either of the two main groups of living mammals—Theria, including placentals and marsupials, and MonotremataAgustí-Antón 2002, pp 3-4—but usually as closer to Theria than to monotremes. They are considered to be clos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plagiaulacida
Plagiaulacida is a group of extinct multituberculate mammals. Multituberculates were among the most common mammals of the Mesozoic, "the age of the dinosaurs". Plagiaulacids are a paraphyletic grouping, containing all multituberculates that lie outside of the advanced group Cimolodonta. They ranged from the Middle Jurassic Period to the early Late Cretaceous of the northern hemisphere. During the Cenomanian, they were replaced by the more advanced cimolodontans. Kielan-Jaworowska and Hurum (2001) divides “Plagiaulacida” into three informal lineages, the paulchoffatiids, the plagiaulicids, and the allodontids. Allodontid line The Allodontid line may be a superfamily, Allodontoidea. Both allodontids and paulchoffatiids (below) were among the most basal of the plagiaulacids. The Allodontid line contains: The family Allodontidae is known from two genera from the Upper Jurassic Morrison Formation of North America. The family Zofiabaataridae contains a single genus, '' ...

René Lavocat
René Lavocat (August 24, 1909-August 9, 2007) was a French paleontologist who described several genera of African dinosaurs including the sauropod '' Rebbachisaurus'', as well as several extinct mammals such as the family Kenyamyidae. The mammal ''Lavocatia'', the notosuchian '' Lavocatchampsa'', the sauropod ''Lavocatisaurus'' and the phorusrhacid '' Lavocatavis'' are named after him. Paleontological discoveries Eager to try paleontological research in Africa to find Oligocene mammals, Le Père Lavocat, éminent paléontologue, dans les Kem-Kem'' Lavocat was strongly endorsed by Camille Arambourg. In 1947, he obtained leadership of a research mission in the Algerian-Moroccan desert. He did not find any Oligocene mammals, but instead came across a rich fauna of Cretaceous vertebrates. His first notes on this subject were made in 1948 entitled ''les Comptes Rendus Sommaires de la Société géologique de France'' (''English: Report Summary to the Geological Society of France ...

Pinheirodontidae
Pinheirodontidae is a poorly known family of fossil mammals which belong to the informal suborder "Plagiaulacida" within the order Multituberculata. Remains are known from the Late Jurassic to Early Cretaceous of Europe, (predominantly Portugal and Spain), but are so far restricted to teeth. The family Pinheirodontidae was named by Hahn G. and Hahn R. in 1999, after the locality of Porto Dinheiro Porto Dinheiro (or Praia de Porto Dinheiro) is a locality in the civil parish (''freguesia'') of Ribamar, municipality of Lourinhã, in Portugal. It is known as a rich fossil locality, from where were found many Late Jurassic dinosaurs and mammals ..., in central west Portugal. References * Hahn & Hahn (1999), "Pinheirodontidae n. fam.

Early Cretaceous
The Early Cretaceous (geochronological name) or the Lower Cretaceous ( chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java- Manihiki- Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kergue ...

Fossils Of Spain
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 absolute ...

Barremian Life
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''. Regional equivalents The Barremian falls in the Gallic epoch, a subdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous Mammals Of Europe
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic 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 ''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 eustatic sea levels that created numerous shallow 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 appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by ...

Peramus
''Peramus'' is an extinct genus of cladotherian mammal. It lived in the Late Jurassic and Early Cretaceous of Europe and North Africa. Species There are three known extinct species in the genus: * '' Peramus dubius'' Lulworth Formation, United Kingdom, Berriasian * '' Peramus minor'' Lulworth Formation, United Kingdom, Berriasian * '' Peramus tenuirostris'' Lulworth Formation, United Kingdom, Berriasian Additionally, indeterminate remains are known from the Ksar Metlili Formation of Morocco, dating to the Tithonian-Berriasian, and the Angeac-Charente bonebed in France, dating to the Berriasian. Phylogeny ''Peramus'' is generally considered an advanced cladotherian. In the analysis performed by Panciroli and colleagues (2018), ''Peramus'' was recovered as within a clade also including '' Palaeoxonodon'' and '' Amphitherium,'' as derived members of Cladotheria. ''Peramus'', ''Palaeoxonodon'' and ''Amphitherium'' were united by the shared traits of "convergence of the Meckel� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galve, Teruel
Galve is a municipality located in the province of Teruel, Aragon, Spain. According to the 2006 census (INE), the municipality has a population of 145 inhabitants. There is an important paleontological site. Paleontological significance The Galve area is a productive area full of fossil sites well known for its faunal assemblage of dinosaurs, notably the sauropods and mammals. This region is also noted for its lissamphibians, lizards and turtles, as well as diverse multituberculates, dryolestoids, and spalacotheriids. Spanish paleontologists have worked this site for years, including José Ignacio Canudo, José Luis Barco, Gloria Cuenca-Bescós, and José Ignacio Ruiz-Omeñaca. The Galve region sediments date back to the Late Jurassic–Early Cretaceous, with five formations ranging in age from Tithonian to Aptian listed below: * Higueruelas Formation (Tithonian) * Villar del Arzobispo Formation (upper Tithonian-middle Berriasian) * El Castellar Formation (upper Hauterivian ...
