Animal

Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia.

See Rhaeticosaurus and Animal

A chordate is a deuterostomic animal belonging to the phylum Chordata. All chordates possess, at some point during their larval or adult stages, five distinctive physical characteristics (synapomorphies) that distinguish them from other taxa.

Exter Formation

The Exter Formation is the only formation of the Upper Keuper or Rhätsandstein, and is a geologic formation in Germany.

Extinction

Extinction is the termination of a taxon by the death of its last member.

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.

Late Triassic

The Late Triassic is the third and final epoch of the Triassic Period in the geologic time scale, spanning the time between Ma and Ma (million years ago).

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.

Pliosauroidea

Pliosauroidea is an extinct clade of plesiosaurs, known from the earliest Jurassic to early Late Cretaceous.

Reptile

Reptiles, as commonly defined, are a group of tetrapods with usually an ectothermic ('cold-blooded') metabolism and amniotic development.

Rhaetian

The Rhaetian is the latest age of the Triassic Period (in geochronology) or the uppermost stage of the Triassic System (in chronostratigraphy).

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.
