Iberosuchus Macrodon
''Iberosuchus'' (meaning "Iberian crocodile") is a genus of extinct sebecosuchian mesoeucrocodylian found in Western Europe from the Eocene. Remains from Portugal was described in 1975 by Antunes as a sebecosuchian crocodilian. This genus has one species: ''I. macrodon'' (meaning "large toothed). ''Iberosuchus'' was a carnivore. Unlike the crocodilians today, they were not aquatic but were instead terrestrial. The first of its fossils were cranial remains found in Portugal, and later more fossils were found in France and Spain. They are only known from very fragmentary fossils, elements of the skull, dentary, teeth and osteoderm. History and discovery Remains of a mesocrocodylian were found in Portugal; it was named ''Iberosuchus macrodon'' in 1975 by Antunes, and is assigned as the type species. It was reclassified as a baurusuchid by Robert Carroll in 1988. In 1996 Ortega and colleges extended their range to France, they analyzed the fragmentary fossils of '' Atacisaurus cras ...

Middle Eocene
The Eocene ( ) is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', ' Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in ...

Atacisaurus
''Atacisaurus'' is an extinct dubious genus of gavialoid crocodylian. Fossils have been found in the Grès de Carcassonne Member of the Sables du Castrais Formation in Laure-Minervois, France that date back to the Middle Eocene. Discovery and naming The holotype, discovered in 1919 by M. Finestres in Laure-Minervois and previously housed at the Société d'Etudes Scientifiques de l'Aude, is an anterior portion of a mandible which is now lost, and MHNT.PAL.2012.0.49, a partial skull from a different specimen is also known, which was donated to the History Museum of Toulouse in 1873 by Henri de Sévérac; MHNT.PAL.2012.0.49 has since been partially prepared at sometime between 1931 and 17 April 2016. The type species, ''A. glareae'', was named and described by Gaston Astre in 1931.Astre, G. (1931). "Les crocodiliens fossiles des terrains tertiaires sous pyrénéens".

Supratemporal Fenestra
Temporal fenestrae are openings in the temporal region of the skull of some amniotes, behind the orbit (eye socket). These openings have historically been used to track the evolution and affinities of reptiles. Temporal fenestrae are commonly (although not universally) seen in the fossilized skulls of dinosaurs and other sauropsids (the total group of reptiles, including birds). The major reptile group Diapsida, for example, is defined by the presence of two temporal fenestrae on each side of the skull. The infratemporal fenestra, also called the lateral temporal fenestra or lower temporal fenestra, is the lower of the two and is exposed primarily in lateral (side) view.The supratemporal fenestra, also called the upper temporal fenestra, is positioned above the other fenestra and is exposed primarily in dorsal (top) view. In some reptiles, particularly dinosaurs, the parts of the skull roof lying between the supratemporal fenestrae are thinned out by excavations from the adjacent ...

Postorbital Bone
The ''postorbital'' is one of the bones in vertebrate skulls which forms a portion of the dermal skull roof and, sometimes, a ring about the orbit. Generally, it is located behind the postfrontal and posteriorly to the orbital fenestra. In some vertebrates, the postorbital is fused with the postfrontal to create a postorbitofrontal. Birds have a separate postorbital as an embryo An embryo ( ) is the initial stage of development for a multicellular organism. In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male sp ..., but the bone fuses with the frontal before it hatches.

Right Premaxilla Fossil
Rights are legal, social, or ethical principles of freedom or entitlement; that is, rights are the fundamental normative rules about what is allowed of people or owed to people according to some legal system, social convention, or ethical theory. Rights are an important concept in law and ethics, especially theories of justice and deontology. The history of social conflicts has often involved attempts to define and redefine rights. According to the ''Stanford Encyclopedia of Philosophy'', "rights structure the form of governments, the content of laws, and the shape of morality as it is currently perceived". Types of rights Natural versus legal * Natural rights are rights which are "natural" in the sense of "not artificial, not man-made", as in rights deriving from human nature or from the edicts of a god. They are universal; that is, they apply to all people, and do not derive from the laws of any specific society. They exist necessarily, inhere in every individual, and can ...

Nostril
A nostril (or naris , : nares ) is either of the two orifices of the nose. They enable the entry and exit of air and other gasses through the nasal cavities. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove moisture on exhalation. Fish do not breathe through noses, but they do have two small holes used for smelling, which can also be referred to as nostrils (with the exception of Cyclostomi, which have just one nostril). In humans, the nasal cycle is the normal ultradian cycle of each nostril's blood vessels becoming engorged in swelling, then shrinking. The nostrils are separated by the septum. The septum can sometimes be deviated, causing one nostril to appear larger than the other. With extreme damage to the septum and columella, the two nostrils are no longer separated and form a single larger external opening. Like other tetrapod A tetrapod (; from Ancient Greek :wikti ...
