Laidleria, the Glossary

Laidleria is an extinct genus of temnospondyl that likely lived between the Early to Middle Triassic, though its exact stratigraphic range is less certain.^[1]

Amphibian

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

See Laidleria and Amphibian

Animal

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

Anisian

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.

Capitosauria

Capitosauria is an extinct group of large temnospondyl amphibians with simplified stereospondyl vertebrae.

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.

Cynognathus Assemblage Zone

The Cynognathus Assemblage Zone is a tetrapod biozone utilized in the Karoo Basin of South Africa. Laidleria and Cynognathus Assemblage Zone are Triassic South Africa.

James Kitching

James William Kitching (6 February 1922 – 24 December 2003) was a South African vertebrate palaeontologist and regarded as one of the world’s greatest fossil finders.

Laidleria

Laidleria is an extinct genus of temnospondyl that likely lived between the Early to Middle Triassic, though its exact stratigraphic range is less certain. Laidleria and Laidleria are Anisian life, fossil taxa described in 1957, fossils of South Africa, middle Triassic animals of Africa, taxa named by James Kitching, Triassic South Africa and Triassic temnospondyls of Africa.

Middle Triassic

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 chronostratigraphy.

Olenekian

In the geologic timescale, the Olenekian is an age in the Early Triassic epoch; in chronostratigraphy, it is a stage in the Lower Triassic series.

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.

Plagiosauroidea

Plagiosauroidea is a superfamily of stereospondyl temnospondyls that lived in the Triassic period.

Species

A species (species) is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction.

Temnospondyli

Temnospondyli (from Greek τέμνειν, temnein 'to cut' and σπόνδυλος, spondylos 'vertebra') or temnospondyls is a diverse ancient order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian and Triassic periods, with fossils being found on every continent.

See Laidleria and Temnospondyli

Trematosauria

Trematosauria is one of two major groups of temnospondyl amphibians that survived the Permian-Triassic extinction event, the other (according to Yates and Warren 2000) being the Capitosauria.

See Laidleria and Trematosauria

Triassic

The Triassic (sometimes symbolized 🝈) is a geologic period and system which spans 50.5 million years from the end of the Permian Period 251.902 million years ago (Mya), to the beginning of the Jurassic Period 201.4 Mya.

See Laidleria and Triassic

Type species

In zoological nomenclature, a type species (species typica) is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen (or specimens).

Uruyiella

Uruyiella is an extinct genus of laidleriid temnospondyl from Late Triassic Buena Vista Formation of Uruguay.
