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 Ichthyosauromorpha and Apomorphy and synapomorphy

Archelosauria

Archelosauria is a clade grouping turtles and archosaurs (birds and crocodilians) and their fossil relatives, to the exclusion of lepidosaurs (the clade containing lizards, snakes and the tuatara).

See Ichthyosauromorpha and Archelosauria

Archosauromorpha (Greek for "ruling lizard forms") is a clade of diapsid reptiles containing all reptiles more closely related to archosaurs (such as crocodilians and dinosaurs, including birds) rather than lepidosaurs (such as tuataras, lizards, and snakes).

See Ichthyosauromorpha and Archosauromorpha

Baisesaurus

Baisesaurus (meaning "Baise lizard") is an extinct genus of ichthyosauromorph from the early Triassic (Spathian) Luolou Formation of Guangxi, China.

See Ichthyosauromorpha and Baisesaurus

Cartorhynchus

Cartorhynchus (meaning "shortened snout") is an extinct genus of early ichthyosauriform marine reptile that lived during the Early Triassic epoch, about 248 million years ago.

See Ichthyosauromorpha and Cartorhynchus

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 Ichthyosauromorpha and Clade

Cretaceous

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

See Ichthyosauromorpha and Cretaceous

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 Ichthyosauromorpha and Diapsid

Early Triassic

The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale.

See Ichthyosauromorpha and Early Triassic

Fibula

The fibula (fibulae or fibulas) or calf bone is a leg bone on the lateral side of the tibia, to which it is connected above and below.

See Ichthyosauromorpha and Fibula

Humerus

The humerus (humeri) is a long bone in the arm that runs from the shoulder to the elbow.

See Ichthyosauromorpha and Humerus

Hupehsuchia

Hupehsuchia is an order of diapsid reptiles closely related to ichthyosaurs.

See Ichthyosauromorpha and Hupehsuchia

Hupehsuchus

Hupehsuchus is an extinct genus of small marine reptiles, about 1 m (3 ft) long, found in the area of Hubei in China.

See Ichthyosauromorpha and Hupehsuchus

Ichthyopterygia

Ichthyopterygia ("fish flippers") was a designation introduced by Sir Richard Owen in 1840 to designate the Jurassic ichthyosaurs that were known at the time, but the term is now used more often for both true Ichthyosauria and their more primitive early and middle Triassic ancestors. Ichthyosauromorpha and Ichthyopterygia are ichthyosauromorphs and Turonian extinctions.

See Ichthyosauromorpha and Ichthyopterygia

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. Ichthyosauromorpha and Ichthyosauria are Olenekian first appearances and Turonian extinctions.

See Ichthyosauromorpha and Ichthyosauria

Ichthyosauriformes

The Ichthyosauriformes are a group of marine reptiles, belonging to the Ichthyosauromorpha, that lived during the Mesozoic. Ichthyosauromorpha and Ichthyosauriformes are ichthyosauromorphs, Olenekian first appearances and Turonian extinctions.

See Ichthyosauromorpha and Ichthyosauriformes

Ichthyosaurus

Ichthyosaurus (derived from Greek ἰχθύς (ichthys) meaning 'fish' and σαῦρος (sauros) meaning 'lizard') is a genus of ichthyosaurs from the Early Jurassic (Hettangian - Pliensbachian), with possible Late Triassic record, from Europe (Belgium, England, Germany, Switzerland, and Portugal).

See Ichthyosauromorpha and Ichthyosaurus

Late Cretaceous

The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale.

See Ichthyosauromorpha and Late Cretaceous

Marine reptile

Marine reptiles are reptiles which have become secondarily adapted for an aquatic or semiaquatic life in a marine environment.

See Ichthyosauromorpha and Marine reptile

Mesozoic

The Mesozoic Era is the penultimate era of Earth's geological history, lasting from about, comprising the Triassic, Jurassic and Cretaceous Periods.

See Ichthyosauromorpha and Mesozoic

Most recent common ancestor

In biology and genetic genealogy, the most recent common ancestor (MRCA), also known as the last common ancestor (LCA), of a set of organisms is the most recent individual from which all the organisms of the set are descended.

Norway

Norway (Norge, Noreg), formally the Kingdom of Norway, is a Nordic country in Northern Europe, situated on the Scandinavian Peninsula.

Omphalosauridae

Omphalosauridae is an extinct family of Ichthyosauriformes known from the Early to Late Triassic of Europe, North America, and Asia.

See Ichthyosauromorpha and Omphalosauridae

Permian

The Permian is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya.

See Ichthyosauromorpha and Permian

Permian–Triassic extinction event

Approximately 251.9 million years ago, the Permian–Triassic (P–T, P–Tr) extinction event (PTME; also known as the Late Permian extinction event, the Latest Permian extinction event, the End-Permian extinction event, and colloquially as the Great Dying) forms the boundary between the Permian and Triassic geologic periods, and with them the Paleozoic and Mesozoic eras.

See Ichthyosauromorpha and Permian–Triassic extinction event

Primitive (phylogenetics)

In phylogenetics, a primitive (or ancestral) character, trait, or feature of a lineage or taxon is one that is inherited from the common ancestor of a clade (or clade group) and has undergone little change since.

See Ichthyosauromorpha and Primitive (phylogenetics)

Radius (bone)

The radius or radial bone (radii or radiuses) is one of the two large bones of the forearm, the other being the ulna.

See Ichthyosauromorpha and Radius (bone)

Sauropterygia

Sauropterygia ("lizard flippers") is an extinct taxon of diverse, aquatic reptiles that developed from terrestrial ancestors soon after the end-Permian extinction and flourished during the Triassic before all except for the Plesiosauria became extinct at the end of that period.
