List of informally named Mesozoic reptiles
Open-knowledge reference entry

This list of informally named Mesozoic reptiles is a listing of prehistoric reptiles from the Mesozoic era (excluding dinosaurs) 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. 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.
This list also includes names published in self-published or predatory journals.

Why this record matters
A short description can identify a subject without explaining its stakes. For “List of informally named Mesozoic reptiles”, the useful work is to connect “open-knowledge reference entry” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q133142061. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1967.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
