Description: Here is a neat little piece of lower jaw from a leptomeryx Deer. It is a partial lower jaw with a nice chunk of the left side intact. I prepped it and left it with the matrix on the bottom. My airblaster hasn't been working very well lately or I could have cleaned the teeth better. Cool display piece that sits nicely and measures about 1 x 1.5 inches. Cool fossil from the oligocene epoch.LeptomeryxFrom Wikipedia, the free encyclopediaJump to navigationJump to searchLeptomeryx Temporal range: middle Eocene to Late Oligocene[1]Skeleton, Paleontology Museum of ZurichScientific classificationKingdom:AnimaliaPhylum:ChordataClass:MammaliaOrder:ArtiodactylaFamily:†LeptomerycidaeSubfamily:†LeptomerycinaeGenus:†Leptomeryx Leidy, 1853Type species†Leptomeryx evansi Species[2]†L. blacki†L. evansi†L. mammifer†L. obliquidens†L. speciosus†L. yoderiLeptomeryx is an extinct genus of ruminant of the family Leptomerycidae, endemic to North America during the Eocene through Oligocene 38–24.8 Mya, existing for approximately 13.2 million years. It was a small deer-like ruminant with somewhat slender body.Mounted skeletonL. evansiFossil distribution[edit]Sites and species recovered:Titus Canyon, Inyo County, California (L.blacki) ~30.6—33.9 Ma.UNSM Sx-8 (Orella C), Sioux County, Nebraska (L. elissae) ~33.9—24.8 Ma.Anxiety Butte, Saskatchewan, Canada (L. sp., L. evansi) ~38—24.8 Ma.Calf Creek, Saskatchewan, Canada, (L. mammifer) ~38—33.3 Ma.Toadstool Park, Sioux County, Nebraska (L. speciosus) ~37.2—33.3 Ma.[3]Medicine Pole Hills, Bowman County, North Dakota (L. yoderi) ~38—33.9 Ma.[4]References[edit]^ Webb, 1998, p. 474.^ Webb, 1998, p.471.^ Paleobiology database: Toadstool Park collection^ Paleobiology database: Medicine Pole Hills collectionWebb, S.D., 1998.
