2012 in paleontology
From Wikipedia, the free encyclopedia
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils.[1] This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2012.
Note: In 2012, the International Code of Zoological Nomenclature was amended, with new regulations allowing the publication of new names and nomenclatural acts in zoology after 2011, in works "produced in an edition containing simultaneously obtainable copies by a method that assures [...] widely accessible electronic copies with fixed content and layout", provided that the work is registered in ZooBank before it is published, the work itself states the date of publication with evidence that registration has occurred, and the ZooBank registration states both the name of an electronic archive intended to preserve the work and the ISSN or ISBN associated with the work.[2][3] New scientific names appearing in electronic works are not required to be registered in ZooBank, only the works themselves are.[2] Works containing descriptions of some of the taxa listed below were not printed on paper in 2012; however, the taxa that were described in works which were registered in ZooBank in 2012 are listed as valid.

Spielmann & Lucas |
Late Triassic |
A vertebrate of uncertain phylogenetic placement. Described on the basis of three postcanine teeth, considered to be teeth of a trirachodontid cynodont by Lucas et al. (1999)[185] and Spielmann and Lucas (2012).[184] On the other hand, Abdala, Neveling and Welman (2006) and Sidor and Hopson (2018) did not consider it likely that Redondagnathus was a member of Trirachodontidae, and Abdala, Neveling and Welman (2006) weren't even sure whether it was a cynodont.[186][187] The type species is Redondagnathus hunti. |
