Anhanguera (pterosaur)
''Anhanguera'' () is a genus of Pterodactyloidea, pterodactyloid pterosaur known from the Early Cretaceous (Albian age, 112 to 100 million years ago) Romualdo Formation of Brazil (precisely in Araripe Basin) and the Late Cretaceous (Cenomanian age, 98 to 93 million years ago) Kem Kem Group of Morocco. This pterosaur is closely related to ''Ornithocheirus'', but belongs in the family Anhangueridae.Campos, D. de A., and Kellner, A. W. (1985). "Um novo exemplar de ''Anhanguera blittersdorffi'' (Reptilia, Pterosauria) da formação Santana, Cretaceo Inferior do Nordeste do Brasil." In Congresso Brasileiro de Paleontologia, Rio de Janeiro, Resumos, p. 13. The generic name comes from the Tupi language, Tupi words ''añanga'', meaning "spirit protector of the animals" + ''wera'' "bygone".

Albian
The Albian is both an age (geology), age of the geologic timescale and a stage (stratigraphy), stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early Cretaceous, Early/Lower Cretaceous epoch (geology), Epoch/series (stratigraphy), Series. Its approximate time range is 113.0 ± 1.0 annum, Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for Aube (river), River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan ''Hedbergellidae, Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithocheirus
''Ornithocheirus'' (from Ancient Greek "ὄρνις", meaning bird, and "χεῖρ", meaning hand) is a pterosaur genus known from fragmentary fossil remains uncovered from sediments in the United Kingdom and possibly Morocco. Several species have been referred to the genus, most of which are now considered as dubious species, or members of different genera, and the genus is now often considered to include only the type species, ''Ornithocheirus simus''. Species have been referred to ''Ornithocheirus'' from the mid-Cretaceous period of North America, Europe and South America, but ''O. simus'' is known mostly from the United Kingdom, though a specimen referred to ''O.'' cf. ''simus'' is also known from the Late Cretaceous Kem Kem Group of Morocco. Because ''O. simus'' was originally named based on poorly preserved fossil material, the genus ''Ornithocheirus'' has suffered enduring problems of zoological nomenclature. Fossil remains of ''Ornithocheirus'' have been recovered mainly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceará
Ceará (, ) is one of the 26 states of Brazil, located in the Northeast Region, Brazil, northeastern part of the country, on the Atlantic Ocean, Atlantic coast.

Santana Formation
The Santana Group is a geologic group, formerly included as the middle part of the Araripe Group, in the Araripe Basin of northeastern Brazil. The group comprises the Crato, Ipubi and Romualdo Formations and is dated to the Aptian to Albian stages of the Early Cretaceous. The formations of the group were deposited in a lacustrine to subtidal shallow marine environment in the Araripe rift basin.Santana Group at Fossilworks.org The Santana Group has provided a rich assemblage of fossils; flora, fish, arthropods insects, turtles, snakes, dinosaurs including '' Irritator'', and pterosaurs such as '' [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sclerotic Ring
The scleral ring or sclerotic ring is a hardened ring of plates, often derived from bone, that is found in the eyes of many animals in several groups of vertebrates. Some species of mammals, amphibians, and crocodilians lack scleral rings. The ring is in the fibrous outer layer of the eye, called the sclera. The structure is commonly referred to as the sclerotic ring; but, because the word ''sclerotic'' often implies pathology of the sclera (''see'' " sclerosis", an unrelated medical condition), recent authors have urged avoiding the use of this term, to avoid confusion and to increase the utility of character comparisons. Scleral rings can be made of cartilaginous material (scleral cartilage) or bony material (scleral ossicles), or often a combination of both, that comes together to form a ring. The arrangement, size, shape, and number of ossicles vary by group. They are believed to have a role in supporting the eye, especially in animals whose eyes are not spherical, or which liv ...

Balance (ability)
Balance in biomechanics, is an ability to maintain the line of gravity (vertical line from centre of mass) of a body within the base of support with minimal postural sway. Sway is the horizontal movement of the centre of gravity even when a person is standing still. A certain amount of sway is essential and inevitable due to small perturbations within the body (e.g., breathing, shifting body weight from one foot to the other or from forefoot to rearfoot) or from external triggers (e.g., visual distortions, floor translations). An increase in sway is not necessarily an indicator of dysfunctional balance so much as it is an indicator of decreased sensorimotor control. Maintaining balance Maintaining balance requires coordination of input from multiple sensory nervous system, sensory systems including the vestibular system, vestibular, somatosensory system, somatosensory, and visual systems. * Vestibular system: sense organs that regulate equilibrium (equilibrioception); directiona ...

Inner Ear
The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates, the inner ear is mainly responsible for sound detection and balance. In mammals, it consists of the bony labyrinth, a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: * The cochlea, dedicated to hearing; converting sound pressure patterns from the outer ear into electrochemical impulses which are passed on to the brain via the auditory nerve. * The vestibular system, dedicated to balance (ability), balance. The inner ear is found in all vertebrates, with substantial variations in form and function. The inner ear is innervated by the eighth cranial nerve in all vertebrates. Structure The labyrinth can be divided by layer or by region. Bony and membranous labyrinths The bony labyrinth, or osseous labyrinth, is the network of passages with bony walls lined with periosteum. The three major parts of the bony labyrin ...

Ludodactylus
''Ludodactylus'' (meaning "play finger") is a genus of anhanguerid pterodactyloid pterosaur from the Early Cretaceous period (Aptian stage) of what is now the Crato Formation of the Araripe Basin in Ceará, Brazil. The type species, type and only species is ''L. sibbicki''. The genus, generic name ''Ludodactylus'' refers to the fact that the animal had the combination of teeth and a ''Pteranodon''-like head crest, similar to many toy pterosaurs, and no such creature was known to exist until the discovery of ''Ludodactylus''. However, ''Ludodactylus'' is not the only pterosaur now known to possess these features, its very close relative ''Caulkicephalus'' is another example. Etymology The genus was named by Eberhard Frey ''et al.'' in 2003 and contains one known species, ''Ludodactylus sibbicki''. The name is derived from Latin ''ludus'', "play" and Greek ''daktylos'', "finger". ''Ludus'' refers to the fact, long lamented by paleontologists, that many toy pterosaurs combined teeth ...

Pteranodontidae
The Pteranodontidae are a Family (biology), family of large pterosaurs from the Late Cretaceous of North America and possibly other continents including Europe and Africa. The family was named in 1876 by Othniel Charles Marsh. Pteranodontids had a distinctive, elongated crest jutting from the rear of the head (most famously seen in ''Pteranodon'' itself). The spectacularly-crested ''Nyctosaurus'' is sometimes included in this family, though usually placed in its own family, the Nyctosauridae (Nicholson & Lydekker, 1889). Modern researchers differ in their use of the concept. S. Christopher Bennett and Alexander Kellner have concluded that ''Nyctosaurus'' was not a pteranodontid. In 1994 Bennett defined a clade Pteranodontidae, also including species of the Ornithocheiromorpha. However, this definition has not been accepted by other workers. Alexander Kellner, for example, named several additional species for specimens previously classified as ''Pteranodon'', and placed ''P. sternbe ...

Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...
