Adaptation

In biology, adaptation has three related meanings.

See Sahonachelys and Adaptation

Anatomical terms of location

Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans.

See Sahonachelys and Anatomical terms of location

Aquatic animal

An aquatic animal is any animal, whether vertebrate or invertebrate, that lives in water for all or most of its lifetime.

See Sahonachelys and Aquatic animal

Aquatic feeding mechanisms

Aquatic feeding mechanisms face a special difficulty as compared to feeding on land, because the density of water is about the same as that of the prey, so the prey tends to be pushed away when the mouth is closed.

See Sahonachelys and Aquatic feeding mechanisms

Araripemydidae

Araripemydidae is a family of freshwater aquatic turtles belonging to the order Pleurodira (side-necked turtles), known from the Early Cretaceous of South America and Africa. Sahonachelys and Araripemydidae are pleurodira.

Archosaur

Archosauria or archosaurs is a clade of diapsid sauropsid tetrapods, with birds and crocodilians being the only extant representatives.

See Sahonachelys and Archosaur

Binomial nomenclature

In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages.

See Sahonachelys and Binomial nomenclature

Bothremydidae

Bothremydidae is an extinct family of side-necked turtles (Pleurodira) known from the Cretaceous and Cenozoic. Sahonachelys and Bothremydidae are pleurodira.

Clade

In biological phylogenetics, a clade, also known as a monophyletic group or natural group, is a grouping of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree.

See Sahonachelys and Clade

Cretaceous

The Cretaceous is a geological period that lasted from about 145 to 66 million years ago (Mya).

Evolution

Evolution is the change in the heritable characteristics of biological populations over successive generations.

See Sahonachelys and Evolution

Genus

Genus (genera) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses.

Holotype

A holotype is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described.

See Sahonachelys and Holotype

Hyoid bone

The hyoid bone (lingual bone or tongue-bone) is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage.

See Sahonachelys and Hyoid bone

Insect

Insects (from Latin insectum) are hexapod invertebrates of the class Insecta.

Jainemys

Jainemys (meaning "Jain's Turtle") is an extinct genus of bothremydid pleurodiran turtle that has been found in the Lameta Formation, India. Originally described by Sohan Lal Jain in 1977 under the name "Carteremys" pisdurensis,Jain, S. L. (1977). A new fossil pelomedusid turtle from the Upper Cretaceous Pisdura sediments, central India. Sahonachelys and Jainemys are Prehistoric turtle genera.

Limb (anatomy)

A limb (from Old English lim, meaning "body part") is a jointed, muscled appendage of a tetrapod vertebrate animal used for weight-bearing, terrestrial locomotion and physical interaction with other objects.
