Eotetrapodiformes, the Glossary

Eotetrapodiformes is a clade of tetrapodomorphs including the four-limbed vertebrates ("tetrapods" in the traditional sense) and their closest finned relatives, two groups of stem tetrapods called tristichopterids and elpistostegalids.^[1]

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 Eotetrapodiformes and Clade

Colosteidae

Colosteidae is a family of stegocephalians (stem-group tetrapods) that lived in the Carboniferous period.

Crassigyrinus

Crassigyrinus (from crassus, 'thick' and γυρίνος gyrínos, 'tadpole') is an extinct genus of carnivorous stem tetrapod from the Early Carboniferous Limestone Coal Group of Scotland and possibly Greer, West Virginia.

See Eotetrapodiformes and Crassigyrinus

Crown group

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 Eotetrapodiformes and Crown group

Elginerpeton

Elginerpeton is a genus of stegocephalian (stem-tetrapod), the fossils of which were recovered from Scat Craig, Morayshire in the UK, from rocks dating to the late Devonian Period (Late Frasnian stage, 375 million years ago).

See Eotetrapodiformes and Elginerpeton

Elpistostegalia

Elpistostegalia is a clade containing Panderichthys and all more derived tetrapodomorph taxa.

See Eotetrapodiformes and Elpistostegalia

Elpistostege

Elpistostege is an extinct genus of finned tetrapodomorphs that lived during the Frasnian age of the Late Devonian epoch.

Endocranium

The endocranium in comparative anatomy is a part of the skull base in vertebrates and it represents the basal, inner part of the cranium.

See Eotetrapodiformes and Endocranium

Ethmoid bone

The ethmoid bone (from sieve) is an unpaired bone in the skull that separates the nasal cavity from the brain.

See Eotetrapodiformes and Ethmoid bone

Eusthenopteron

Eusthenopteron (from εὖ, 'good', σθένος, 'strength', and πτερόν 'wing' or 'fin') is a genus of prehistoric sarcopterygian (often called "lobe-finned") fish known from several species that lived during the Late Devonian period, about 385 million years ago.

See Eotetrapodiformes and Eusthenopteron

Fish fin

Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim.

See Eotetrapodiformes and Fish fin

Holocene

The Holocene is the current geological epoch, beginning approximately 11,700 years ago.

See Eotetrapodiformes and Holocene

Holotype

A holotype is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described.

See Eotetrapodiformes and Holotype

Ichthyostega

Ichthyostega (from ἰχθῦς, 'fish' and στέγη, 'roof') is an extinct genus of limbed tetrapodomorphs from the Late Devonian of what is now Greenland. Eotetrapodiformes and Ichthyostega are Evolution of tetrapods.

Laurasia

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

Megalichthyiformes

Megalichthyiformes is an extinct clade of basal tetrapodomorphs which first appeared during the Devonian period.

See Eotetrapodiformes and Megalichthyiformes

Middle Devonian

In the geological timescale, the Middle Devonian epoch (from 397.5 ± 2.7 million years ago to 385.3 ± 2.6 million years ago) occurred during the Devonian period, after the end of the Emsian age.

See Eotetrapodiformes and Middle Devonian

Panderichthys

Panderichthys is a genus of extinct sarcopterygian (lobe-finned fish) from the late Devonian period, about 380 Mya.

Paraphyly

Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages.

See Eotetrapodiformes and Paraphyly

Parasphenoid

The parasphenoid is a bone which can be found in the cranium of many vertebrates.

See Eotetrapodiformes and Parasphenoid

Platycephalichthys

Platycephalichthys is a genus of tristichopterid lobe-finned fish which lived during the Upper Devonian, Frasnian stage. Eotetrapodiformes and Platycephalichthys are Eotetrapodiforms.

See Eotetrapodiformes and Platycephalichthys

Rhizodontida

Rhizodontida is an extinct group of predatory tetrapodomorphs known from many areas of the world from the Givetian through to the Pennsylvanian - the earliest known species is about 377 million years ago (Mya), the latest around 310 Mya.

See Eotetrapodiformes and Rhizodontida

Sarcopterygii

Sarcopterygii — sometimes considered synonymous with Crossopterygii — is a clade (traditionally a class or subclass) including both a group of bony fish commonly referred to as lobe-finned fish, and tetrapods.

See Eotetrapodiformes and Sarcopterygii

Sphenoid bone

The sphenoid bone is an unpaired bone of the neurocranium.

Stem tetrapoda

The Stem Tetrapoda are a cladistically defined group, consisting of all animals more closely related to extant four-legged vertebrates than to their closest extant relatives (the lungfish), but excluding the crown group Tetrapoda.

See Eotetrapodiformes and Stem tetrapoda

Tetrapod

A tetrapod is any four-limbed vertebrate animal of the superclass Tetrapoda. Eotetrapodiformes and tetrapod are extant Devonian first appearances.

See Eotetrapodiformes and Tetrapod

Tetrapodomorpha

Tetrapodomorpha (also known as Choanata) is a clade of vertebrates consisting of tetrapods (four-limbed vertebrates) and their closest sarcopterygian relatives that are more closely related to living tetrapods than to living lungfish.

See Eotetrapodiformes and Tetrapodomorpha

Tiktaalik

Tiktaalik (Inuktitut ᑎᒃᑖᓕᒃ) is a monospecific genus of extinct sarcopterygian (lobe-finned fish) from the Late Devonian Period, about 375 Mya (million years ago), having many features akin to those of tetrapods (four-legged animals). Eotetrapodiformes and Tiktaalik are Evolution of tetrapods.
