Amniote

Amniotes are tetrapod vertebrate animals belonging to the clade Amniota, a large group that comprises the vast majority of living terrestrial and semiaquatic vertebrates.

See Temporal fenestra and Amniote

Amphibian

Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia.

See Temporal fenestra and Amphibian

Anapsid

An anapsid is an amniote whose skull lacks one or more skull openings (fenestra, or fossae) near the temples.

See Temporal fenestra and Anapsid

Captorhinidae

Captorhinidae is an extinct family of tetrapods, typically considered primitive reptiles, known from the late Carboniferous to the Late Permian.

See Temporal fenestra and Captorhinidae

In phylogenetics, the crown group or crown assemblage is a collection of species composed of the living representatives of the collection, the most recent common ancestor of the collection, and all descendants of the most recent common ancestor.

See Temporal fenestra and Crown group

Cynodontia

Cynodontia is a clade of eutheriodont therapsids that first appeared in the Late Permian (approximately 260 mya), and extensively diversified after the Permian–Triassic extinction event.

See Temporal fenestra and Cynodontia

Diapsid

Diapsids ("two arches") are a clade of sauropsids, distinguished from more primitive eureptiles by the presence of two holes, known as temporal fenestrae, in each side of their skulls.

See Temporal fenestra and Diapsid

Dinosaur

Dinosaurs are a diverse group of reptiles of the clade Dinosauria.

See Temporal fenestra and Dinosaur

Euryapsida

Euryapsida is a polyphyletic (unnatural, as the various members are not closely related) group of sauropsids that are distinguished by a single temporal fenestra, an opening behind the orbit, under which the post-orbital and squamosal bones articulate.

See Temporal fenestra and Euryapsida

Haplorhini

Haplorhini, the haplorhines (Greek for "simple-nosed") or the "dry-nosed" primates is a suborder of primates containing the tarsiers and the simians (Simiiformes or anthropoids), as sister of the Strepsirrhini ("moist-nosed").

See Temporal fenestra and Haplorhini

Homology (biology)

In biology, homology is similarity due to shared ancestry between a pair of structures or genes in different taxa.

See Temporal fenestra and Homology (biology)

Ichthyosauria

Ichthyosauria (Ancient Greek for "fish lizard" – and) is an order of large extinct marine reptiles sometimes referred to as "ichthyosaurs", although the term is also used for wider clades in which the order resides.

See Temporal fenestra and Ichthyosauria

Jugal bone

The jugal is a skull bone found in most reptiles, amphibians and birds.

See Temporal fenestra and Jugal bone

Mammal

A mammal is a vertebrate animal of the class Mammalia.

See Temporal fenestra and Mammal

Massospondylus

Massospondylus (from Greek, μάσσων (massōn, "longer") and σπόνδυλος (spondylos, "vertebra")) was a genus of sauropodomorph dinosaur from the Early Jurassic (Hettangian to Pliensbachian ages, ca. 200–183 million years ago).

See Temporal fenestra and Massospondylus

Monophyly

In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of taxa which meets these criteria.

See Temporal fenestra and Monophyly

Orbit (anatomy)

In anatomy, the orbit is the cavity or socket/hole of the skull in which the eye and its appendages are situated.

See Temporal fenestra and Orbit (anatomy)

Parareptilia

Parareptilia ("near-reptiles") is an extinct subclass or clade of basal sauropsids/reptiles, typically considered the sister taxon to Eureptilia (the group that likely contains all living reptiles and birds).

See Temporal fenestra and Parareptilia

Phylogenetics

In biology, phylogenetics is the study of the evolutionary history and relationships among or within groups of organisms.

See Temporal fenestra and Phylogenetics

Placodontia

Placodonts ("tablet teeth") are an extinct order of marine reptiles that lived during the Triassic period, becoming extinct at the end of the period.

See Temporal fenestra and Placodontia

Plesiomorphy and symplesiomorphy

In phylogenetics, a plesiomorphy ("near form") and symplesiomorphy are synonyms for an ancestral character shared by all members of a clade, which does not distinguish the clade from other clades.

See Temporal fenestra and Plesiomorphy and symplesiomorphy

Plesiosaur

The Plesiosauria (Greek: πλησίος, plesios, meaning "near to" and ''sauros'', meaning "lizard") or plesiosaurs are an order or clade of extinct Mesozoic marine reptiles, belonging to the Sauropterygia.

See Temporal fenestra and Plesiosaur

Polyphyly

A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor.

See Temporal fenestra and Polyphyly

Postorbital bar

The postorbital bar (or postorbital bone) is a bony arched structure that connects the frontal bone of the skull to the zygomatic arch, which runs laterally around the eye socket.

See Temporal fenestra and Postorbital bar

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.

See Temporal fenestra and Postorbital bone

Quadratojugal bone

The quadratojugal is a skull bone present in many vertebrates, including some living reptiles and amphibians.

See Temporal fenestra and Quadratojugal bone

Skull

The skull is a bone protective cavity for the brain.

See Temporal fenestra and Skull

Squamosal bone

The squamosal is a skull bone found in most reptiles, amphibians, and birds.

See Temporal fenestra and Squamosal bone

Synapsida

Synapsida is one of the two major clades of vertebrate animals in the group Amniota, the other being the Sauropsida (which includes reptiles and birds).

See Temporal fenestra and Synapsida

Taxonomy (biology)

In biology, taxonomy is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics.

See Temporal fenestra and Taxonomy (biology)

Temple (anatomy)

The temple, also known as the pterion, is a latch where four skull bones intersect: the frontal, parietal, temporal, and sphenoid.

See Temporal fenestra and Temple (anatomy)

Temporal fossa

The temporal fossa is a fossa (shallow depression) on the side of the skull bounded by the temporal lines above, and the zygomatic arch below.

See Temporal fenestra and Temporal fossa

Therapsida

Therapsida is a clade comprising a major group of eupelycosaurian synapsids that includes mammals and their ancestors and close relatives.

See Temporal fenestra and Therapsida

Trilophosaurus

Trilophosaurus (Greek for "lizard with three ridges") is a lizard-like trilophosaurid allokotosaur known from the Late Triassic of North America.

See Temporal fenestra and Trilophosaurus

Turtle

Turtles are reptiles of the order Testudines, characterized by a special shell developed mainly from their ribs.

See Temporal fenestra and Turtle

Zygomatic arch

In anatomy, the zygomatic arch, or cheek bone, is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique suture (the zygomaticotemporal suture); the tendon of the temporal muscle passes medial to (i.e.
