context_page_description: This list of informally named dinosaurs is a listing of dinosaurs that have never been given formally published scientific names. This list only includes names that were not properly published 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 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.
  Nicknames or descriptive names given to specimens or taxa by researchers or the press.
context_section_description: "Teihivenator" ("strong hunter") is an improperly named taxon of tyrannosauroid coelurosaur from the Navesink Formation of New Jersey. It was suggested to contain the species, "T." macropus, originally classified as a species of Dryptosaurus (= "Laelaps", a name preoccupied by a mite). It was suggested as a separate genus in 2017 by Chan-gyu Yun. The name "Teihivenator" is invalid because the publication naming it is online-only, which means that a registration with ZooBank is required to be present in the article when published. However, the ZooBank registry was only added in after initial publication, meaning that it fails the requirement to be a validly published taxon.
  In 2017, a preprint paper by Chase Brownstein concluded that the remains of L. macropus are a mixture of tyrannosauroid and ornithomimid elements with no distinguishing characteristics, rendering the species a chimera and a nomen dubium. In 2018, Brownstein stated that a tibia of L. macropus catalogued as specimen AMNH FARB 2550 represents a tyrannosauroid that probably was distinct from Dryptosaurus, but not sufficiently to base a taxon on.
