In biology, adaptation has three related meanings.
Standard anatomical terms of location deal unambiguously with the anatomy of animals, including humans.
In the geologic timescale, the Anisian is the lower stage or earliest age of the Middle Triassic series or epoch and lasted from million years ago until million years ago.
Armour or armor in animals is external or superficial protection against attack by predators, formed as part of the body (rather than the behavioural use of protective external objects), usually through the hardening of body tissues, outgrowths or secretions.
In physics, buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object.
A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises.
Christian Erich Hermann von Meyer (3 September 1801 – 2 April 1869), known as Hermann von Meyer, was a German palaeontologist.
Durophagy is the eating behavior of animals that consume hard-shelled or exoskeleton bearing organisms, such as corals, shelled mollusks, or crabs.
An exoskeleton (from Greek έξω, éxō "outer" and σκελετός, skeletós "skeleton") is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a human.
In geology, a facies (pronounced variously as, or; plural also 'facies') is a body of rock with specified characteristics, which can be any observable attribute of rocks such as their overall appearance, composition, or condition of formation, and the changes that may occur in those attributes over a geographic area.
A fossil (from Classical Latin fossilis; literally, "obtained by digging") is any preserved remains, impression, or trace of any once-living thing from a past geological age.
A geological period is one of several subdivisions of geologic time enabling cross-referencing of rocks and geologic events from place to place.
The Germanic Basin (Germanisches Becken) is a large region of sedimentation in Western and Central Europe that, during the Permian and Triassic periods, extended from England in the west to the eastern border of Poland in the east.
Germany (Deutschland), officially the Federal Republic of Germany (Bundesrepublik Deutschland), is a sovereign state in central-western Europe.
The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.
Henodus chelyops ("Turtle-Faced Single Tooth") was a placodont of the Late Triassic period during the early Carnian age.
In vertebrate anatomy, hip (or "coxa"Latin coxa was used by Celsus in the sense "hip", but by Pliny the Elder in the sense "hip bone" (Diab, p 77) in medical terminology) refers to either an anatomical region or a joint.
The jaw is any opposable articulated structure at the entrance of the mouth, typically used for grasping and manipulating food.
The Ladinian is a stage and age in the Middle Triassic series or epoch.
A limb (from the Old English lim), or extremity, is a jointed, or prehensile (as octopus arms or new world monkey tails), appendage of the human or other animal body.
The maxilla (plural: maxillae) in animals is the upper jawbone formed from the fusion of two maxillary bones.
In the geologic timescale, the Middle Triassic is the second of three epochs of the Triassic period or the middle of three series in which the Triassic system is divided.
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon.
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features.
The neck is the part of the body, on many vertebrates, that separates the head from the torso.
Osteology is the scientific study of bones, practiced by osteologists.
The pelvis (plural pelves or pelvises) is either the lower part of the trunk of the human body between the abdomen and the thighs (sometimes also called pelvic region of the trunk) or the skeleton embedded in it (sometimes also called bony pelvis, or pelvic skeleton).
Placodonts ("Tablet teeth") is an extinct order of marine reptiles that lived during the Triassic period, becoming extinct at the end of the period.
Placodus (meaning 'flat tooth') was a genus of marine reptiles, belonging to the order Placodontia, which swam in the shallow seas of the middle Triassic period (c. 240 million years ago).
Psephoderma (meaning "pebbly skin", from the Ancient Greek psepho (ψῆφος), "pebbly", and derma (δέρμα), "skin" is a genus of placodont that was very similar to its relatives Placochelys and Cyamodus. Psephoderma had a flattened skull and a narrow, straight rostrum. Inside this skull, embedded in the jaws, were rounded teeth specialized for crushing the shellfish it ate. Unlike most placodonts, Psephoderma had a carapace that was divided into two pieces, one on the shoulders and back, another on the rear end. Psephoderma grew to 180 cm long and lived in the Late Triassic (Norian), about 210 million years ago. It was one of the last placodonts to live.
The pterygoid is a paired bone forming part of the palate of many vertebrates, behind the palatine bones.
The quadratojugal is a small jaw bone that is present in most amphibians, reptiles and birds, but has been lost in mammals.
In anatomy, the term rostrum (from the Latin rostrum meaning beak) is used for a number of phylogenetically unrelated structures in different groups of animals.
Sauropterygia ("lizard flippers") is an extinct, diverse taxon of aquatic reptiles that developed from terrestrial ancestors soon after the end-Permian extinction and flourished during the Mesozoic before they became extinct at the end of that era.
Shellfish is a food source and fisheries term for exoskeleton-bearing aquatic invertebrates used as food, including various species of molluscs, crustaceans, and echinoderms.
The skull is a bony structure that forms the head in vertebrates.
In biology, a species is the basic unit of classification and a taxonomic rank, as well as a unit of biodiversity, but it has proven difficult to find a satisfactory definition.
The squamosal is a bone of the head of higher vertebrates.
The tail is the section at the rear end of an animal's body; in general, the term refers to a distinct, flexible appendage to the torso.
The Tethys Ocean (Ancient Greek: Τηθύς), Tethys Sea or Neotethys was an ocean during much of the Mesozoic Era located between the ancient continents of Gondwana and Laurasia, before the opening of the Indian and Atlantic oceans during the Cretaceous Period.
The Triassic is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.9 million years ago (Mya), to the beginning of the Jurassic Period Mya.
Turtles are diapsids of the order Testudines (or Chelonii) characterized by a special bony or cartilaginous shell developed from their ribs and acting as a shield.
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached.
