La Pedrera De Rúbies Formation
The La Pedrera de Rúbies Formation, also called as La Pedrera de Meià is an Early Cretaceous ( late Berriasian to early Barremian geologic formation in Catalonia, Spain. The formation crops out in the area of the Montsec in the Organyà Basin. At the La Pedrera de Meià locality, the formation consists of rhythmically laminated, lithographic limestones that formed in the distal areas of a large, shallow coastal lake. It is noted for the exceptional preservation of articulated small vertebrates and insects, similar to that of the Solnhofen Limestone. Fossil content The La Pedrera de Rúbies Formation has yielded the enantiornithine bird '' Noguerornis'' and the scincogekkomorph lizard '' Pedrerasaurus'',Weishampel et al., 2004, pp. 517-607 and two species of Teiid lizard ''Meyasaurus'', ''M. fauri'' and ''M. crusafonti,'' the indeterminate avialan '' Ilerdopteryx'',Kellner, 2002 frogs '' Neusibatrachus wilferti'',Báez & Sanchiz, 2007, p.477 '' Eodiscoglossus santonjae'' a ...

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness (geology), thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedrerasaurus
''Pedrerasaurus'' is an extinct genus of scincogekkonomorph lizard from the Early Cretaceous (Barremian) La Pedrera de Rúbies Formation of Spain. The type species is ''P. latifrontalis''. It is similar in appearance to ''Meyasaurus'', a widespread Early Cretaceous lizard that is also known from the Iberian Peninsula. Both genera have bicuspid (two- cusped) teeth, but unlike ''Meyasaurus'', ''Pedrerasaurus'' has frontal bone In the human skull, the frontal bone or sincipital bone is an unpaired bone which consists of two portions.''

Fossilworks
Fossilworks was a portal which provides query, download, and analysis tools to facilitate access to the Paleobiology Database, a large relational database assembled by hundreds of paleontologists from around the world. History Fossilworks was created in 1998 by John Alroy and housed at Macquarie University Macquarie University ( ) is a Public university, public research university in Sydney, New South Wales, Australia. Founded in 1964 by the New South Wales Government, it was the third university to be established in the Sydney metropolitan area. ....

Arthropod
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metamerism (biology), metameric) Segmentation (biology), segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior Organ (anatomy), organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired Anatomical terms of location#Dorsal and ventral, ventral Ventral nerve cord, nerve cord ...

Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montsecosuchus
''Montsecosuchus'' is an extinct genus of atoposaurid crocodylomorphs. It is the replacement generic name for ''Alligatorium depereti'', which was described in 1915 from the Montsec Lithographic Limestone quarry of Spain. Fossils found from this locality are from the Early Cretaceous, being Upper Berriasian-Lower Valanginian in age, belonging to the La Pedrera de Rúbies Formation While many publications concerning atoposaurids after 1915 have included mentions of ''A. depereti'', none has offered a redescription or revision of the species, though some recognized that great differences existed between it and other members of the genus. In these publications, the skull of ''A. depereti'' was shorter in relation to body length than any other species of '' Alligatorium'' (being less than half of the presacral length), and this may have been evidence for the genetic distinction of the species, although no replacement name was proposed. However, better preparation of the holotype speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eodiscoglossus
''Eodiscoglossus'' is an extinct genus of prehistoric frogs. It is known from the type species ''E. santonjae'' from the Early Cretaceous (Barremian) La Pedrera de Rúbies Formation and El Castellar Formation of Spain, as well as a referred species ''E. oxoniensis'' known from the Forest Marble Formation of the UK and an indeterminate species from the Dzunbain Formation of Mongolia. It was a small primitive frog, with a length of only from the premaxilla to the ischium. Formerly considered to be closely related to discoglossids, ''E. santonjae'' is now regarded as close to the root of the crown group of modern frogs in a position more derived than New Zealand frogs and tailed frogs, but more basal than costatans like alytids and other more advanced frogs like neobatrachians. The morphology of ''E''. ''santonjae'' suggests a generalist and unspecialised movement habit. The referral of ''E. oxoniensis'' to ''Eodiscoglossus'' has been questioned, as it is much earlier than the typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
