}} Libralces was a genus of Eurasian deer that lived during the Pliocene period. Its main claim to fame are its 2+ meter wide antlers, comparable in size to those of Megaloceros. Libralces fossils have been found from France to Tajikistan,[1] with the best-known examples being the French L. gallicus. According to Jordi Agustí, Libralces was the ancestor of Megaloceros, though most other authorities regard it as a relative of moose, Alces. In the Pleistocene, there were three genera of Holarctic moose-like deer — Cervalces, Alces, and Libralces. In contrast to modern Alces, the Villafranchian Libralces gallicus had very long-beamed, small-palmed antlers and a generalized skull with moderately reduced nasals; the Nearctic Cervalces had longer nasals and more complex antlers than Libralces. Azzaroli 1953 added Alces latiforns to Libralces, but this position has been challenged.[2] Gallery{{Gallery|File:Partial skull of Libralces latifrons.JPG|Partial skull of Libralces latifrons }} References1. ^1 {{Cite web | title = Libralces | publisher = Paleobiology Database | url = http://paleodb.org/cgi-bin/bridge.pl?a=basicTaxonInfo&taxon_no=42677 | accessdate = September 2012}} {{Taxonbar|from=Q568099}}{{Paleo-eventoedungulate-stub}}2. ^{{Cite book | last1 = Kurtén | first1 = Björn | last2 = Anderson | first2 = Elaine | title = Pleistocene Mammals of North America | publisher = Columbia University Press | year = 1980 | isbn = 9780231037334 | page = 315 | url = https://books.google.com/books?id=f8pviaxPIKEC&pg=PA315}} 7 : Prehistoric deer|Pliocene even-toed ungulates|Pliocene mammals of Asia|Pliocene mammals of Europe|Pliocene extinctions|Prehistoric mammal genera|Fossil taxa described in 1952 |
