}}Aelurodon is an extinct canine genus of the subfamily Borophaginae which lived from the Barstovian land mammal age ({{val|16|ul=mya}}) of the middle Miocene to the late Miocene ({{val|5.332|u=mya}}).[2] [3] Aelurodon existed for approximately {{Mya|16-5.3|million years}}. DescriptionAelurodon are a part of a clade of canids loosely known as "bone-crushing" or "hyena-like" dogs, that apparently descended from the earlier genera Protomarctus and Tomarctus.[2] Several species are known from fossils found in the central and western U.S., suggesting a wide geographic range during their peak in the Miocene epoch.[4][2] Large species of Aelurodon (A. ferox and A. taxoides) may have hunted in packs like modern wolves.[5]The evolution of Aelurodon is characterized by the progressive development of teeth adapted to a more hypercarnivorous diet, a trend consistent with other borophagines.[2] The earliest occurrence of the genus is A. asthenostylus dating from 16{{ndash}}{{val|14|ul=Ma}}. This species then gives rise to two different anagenetic clades around 15 Ma. One comprises the species A. montaneis, A. mcgrewi and A. stirtoni, going extinct around 12 Ma. The other clade persists until {{val|5.3|u=Ma}} and includes A. ferox and A. taxoides. A. taxoides is the most derived and largest species in Aelurodon.[1][2] References1. ^1 {{cite journal|last=Wang |first=Xiaoming |author2=Richard Tedford |author3=Beryl Taylor |title=Phylogenetic systematics of the Borophaginae |journal=Bulletin of the American Museum of Natural History |volume=243 |pages=1–391 |date=1999-11-17 |url=http://www.nhm.org/expeditions/rrc/wang/documents/Wangetal1999borophaginemonographpart1.pdf |accessdate=2007-07-08 |format=PDF |hdl=2246/1588 |deadurl=yes |archiveurl=https://web.archive.org/web/20070320023028/http://www.nhm.org/expeditions/rrc/wang/documents/Wangetal1999borophaginemonographpart1.pdf |archivedate=March 20, 2007 |df= }} 2. ^1 2 3 4 5 {{cite journal|last=Wang |first=Xiaoming |author2=Benjamin Wideman |author3=Ralph Nichols |author4=Debra Hanneman |title=A new species of Aelurodon (Carnivora, Canidae) from the Barstovian of Montana |journal=Journal of Vertebrate Paleontology |volume=24 |issue=2 |pages=445–452 |date=June 2004 |url=http://www.nhm.org/expeditions/rrc/wang/documents/Wangetal2004MontanaAelurodon.pdf |accessdate=2015-04-14 |doi=10.1671/2493 |format=PDF |deadurl=yes |archiveurl=https://web.archive.org/web/20081216211915/http://www.nhm.org/expeditions/rrc/wang/documents/Wangetal2004MontanaAelurodon.pdf |archivedate=December 16, 2008 }} 3. ^Aelurodon, Age Range and Collections, PaleoBiology Database yu 4. ^{{cite web|url=http://bnhm.berkeley.edu/browse/vertebrates_Mammalia_Carnivora_Canidae_Aelurodon_all.php |title=Archived copy |accessdate=2006-04-12 |deadurl=yes |archiveurl=https://web.archive.org/web/20110718011855/http://bnhm.berkeley.edu/browse/vertebrates_Mammalia_Carnivora_Canidae_Aelurodon_all.php |archivedate=2011-07-18 |df= }} List of Aelurodon specimens from the Berkeley Natural History Museum.
