This list of informally named dinosaurs is a listing of Paleozoic taxa that have never been given formally published scientific names. This list only includes names that were not properly published ("unavailable names") and have not since been published under a valid name (see list of dinosaur genera for valid names). The following types of names are present on this list:


 * Nomen nudum, Latin for "naked name": A name that has appeared in print but has not yet been formally published by the standards of the International Commission on Zoological Nomenclature. Nomina nuda (the plural form) are invalid, and are therefore not italicized as a proper generic name would be.
 * Nomen manuscriptum, Latin for "manuscript name": A name that appears in manuscript but was not formally published. A nomen manuscriptum is equivalent to a nomen nudum for everything except the method of publication, and description.
 * Nomen ex dissertationae, Latin for "dissertation name": A name that appears in a dissertation but was not formally published.
 * Nicknames or descriptive names given to specimens or taxa by researchers or the press.

Aphol
"Aphol" is a codename of undescribed fish from Carboniferous Bear Gulch Limestone.

Butterfly Animal
"Butterfly Animal" is nickname given to an enigmatic bivalved arthropod from Silurian aged Waukesha Biota. This nickname is given for the fossil's appearance close to unrelated butterflies. Normally around 2 cm wide, there are some isolated carapaces that reach width up to 20 cm.

Coelacanth (Bear Gulch)
"Coelacanth" is a codename of undescribed fish from Bear Gulch Limestone.

Chom
"Chom" is a codename of undescribed fish from Bear Gulch Limestone.

Coch, Coch1
"Coch" and "Coch1" are codenames of undescribed fish from Bear Gulch Limestone.

Cop
"Cop" is a codename of undescribed fish from Bear Gulch Limestone.

Ctenacath (Bear Gulch)
"Ctenacanth" is a codename of undescribed fish from Bear Gulch Limestone. This ctenacanthiform is only described in SVP abstract.

Cladodont (Bear Gulch)
"Cladodont" is a codename of undescribed fish from Bear Gulch Limestone.

Don Juan
"Don Juan" is nickname given for holocephalian (possibly chimaeriform) from Kinney Brick Quarry (Atrasado Formation), known from two males and single female specimens. Its head and skins are covered by denticles, and body shape is similar to that of Callorhinchus.

EBS Collins Monster
"Emu Bay Shale (EBS) Collins Monster" is unofficial name given for luolishaniid lobopodian from Cambrian Emu Bay Shale in Australia. This specimen only preserves front of the body, which consists five pairs of lobopods with spines. The term "Collins Monster" was used as the unofficial name for the luolishaniid lobopodian Collinsovermis before its description.

El weirdo
"El weirdo", or "ElWeir" is a codename of undescribed fish from Bear Gulch Limestone. This chondrichthyan is only described in SVP abstract.

Feroniscus
"Feroniscus hamiltoni" is a palaeonisciform actinopterygian known from Hamilton Quarry. This taxon is only described in thesis.

Fub
"Fub" is a codename of undescribed fish from Bear Gulch Limestone.

Furca mauretanica
"Furca mauretanica" is undescribed marrellomorph from Ordovician Fezouata Formation. It was described as a species of Furca in 2006, but due to that is in doctoral thesis, this name is not considered as valid. This taxa would need separate genus from Furca.

Horizonal cheek
"Horizonal cheek" is a codename of undescribed fish from Bear Gulch Limestone.

Iniop
"Iniop" is a codename of undescribed fish from Bear Gulch Limestone.

Keurbosia
"Keurbosia susanae" is invalid name given for enigmatic animal from Ordovician Soom Shale in South Africa.

Lao
"Lao" is a codename of undescribed fish from Bear Gulch Limestone.

Latromirus/Xus
"Latromirus tridens" is name given for an arthropod from Waukesha Biota. This name is shown in paper in 2016 before description, and then unpublished preprint have shown placeholder name "Xus yus". Most of specimens are later considered to belong to Parioscorpio, while single specimen UWGM 2439 would show separated taxa, possibly cheloniellid.

Little Two Spine
"Little Two Spine" is a codename of undescribed fish from Bear Gulch Limestone.

Long Pelvic
"Long Pelvic" is a codename of undescribed fish from Bear Gulch Limestone.

Mojo
"Mojo" is a codename of undescribed fish from Bear Gulch Limestone.

Mushia
"Mushia" is a nickname of common arthropod fossils known from Devonian Gogo Formation. Chemical analysis shows that is likely to be a crustacean.

Mush mouth
"Mush mouth" is a codename of undescribed fish from Bear Gulch Limestone.

Narrow pop
"Narrow pop" is a codename of undescribed fish from Bear Gulch Limestone.

Norilaspis
"Norilaspis hamata" is a Devonian placoderm from Razvedochnyj Formation in Siberia, considered as nomen nudum.
