Acrodont

Acrodonty (from Greek akros 'highest' + odont- 'tooth') is an anatomical placement of the teeth at the summit of the alveolar ridge of the jaw, without sockets, characteristic of bony fish.

Apomorphy and synapomorphy

In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy).

See Opisthodontia (reptile) and Apomorphy and synapomorphy

Argentina

Argentina, officially the Argentine Republic, is a country in the southern half of South America.

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 Opisthodontia (reptile) and Clade

Cretaceous–Paleogene extinction event

The Cretaceous–Paleogene (K–Pg) extinction event, also known as the Cretaceous–Tertiary extinction, was the mass extinction of three-quarters of the plant and animal species on Earth approximately 66 million years ago.

Eocene

The Eocene is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma).

See Opisthodontia (reptile) and Eocene

Flange

A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails).

See Opisthodontia (reptile) and Flange

Laurasia

Laurasia was the more northern of two large landmasses that formed part of the Pangaea supercontinent from around (Mya), the other being Gondwana.

Mandible

In jawed vertebrates, the mandible (from the Latin mandibula, 'for chewing'), lower jaw, or jawbone is a bone that makes up the lowerand typically more mobilecomponent of the mouth (the upper jaw being known as the maxilla).

See Opisthodontia (reptile) and Mandible

Maxilla

In vertebrates, the maxilla (maxillae) is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones.

Norian

The Norian is a division of the Triassic Period.

Palatine bone

In anatomy, the palatine bones (derived from the Latin palatum) are two irregular bones of the facial skeleton in many animal species, located above the uvula in the throat.
