Animal
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia.
Chordate
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.
Devonian
The Devonian is a geologic period and system of the Paleozoic era during the Phanerozoic eon, spanning 60.3 million years from the end of the preceding Silurian period at million years ago (Ma), to the beginning of the succeeding Carboniferous period at Ma.
Eigil Nielsen (paleontologist)
Eigil Hans Aage Nielsen (16 August 1910 – 8 December 1968) was a Danish paleontologist, who specialized in fossil vertebrate anatomy, particularly of Triassic bony fish.

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.
Geologic time scale
The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth.
See Nielsenia and Geologic time scale
Jean-Pierre Lehman
Jean-Pierre Lehman (10 August 1914 – 26 February 1981) was a French paleontologist who specialized on tetrapods and actinopterygians.
See Nielsenia and Jean-Pierre Lehman
Lungfish
Lungfish are freshwater vertebrates belonging to the class Dipnoi.
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.
