2012 in paleontology

Paleontology or palaeontology (from Greek: paleo, "ancient"; ontos, "being"; and logos, "knowledge") is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. 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.

Contents

Note: In 2012 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. New scientific names appearing in electronic works are not required to be registered in ZooBank, only the works themselves are. Works containing descriptions of some of the taxa listed below weren't printed on paper in 2012; however, the taxa that were described in works which were registered in ZooBank in 2012 are listed as valid.
