This is a femur from a Miocene Period carnivore. The animal was mid-size between a red fox and a coyote. The bone exhibits evidence of having the distal end gnawed off by another carnivore. It has been examined by both the Nebraska State Museum and the Sternberg Museum of Natural History, and neither institution could identify the bone with certainty.
This bone was found by Jessica Respess on October 8, 2001, in a local sandpit, and she graciously donated it to my collection. Jessica was accompanied by her mother Alana, and sisters Amanda and "Sunshine". This was one of the interested groups I had the pleasure of taking fossil hunting.
The bone as shown is 4.5 inches long.
Tapir Jaw and Molar Cap
These three teeth are from a tapir and include the left P/2, P/3, and M/1 (P4 is missing). They are slightly larger than Tapiravus polkensis for the Late Barstovian of Webster County, Nebraska and somewhat smaller than Tapirus johnsoni from the Clarendonian of Cherry County, Nebraska.
This tooth is from a young rhino, M/3 that was unerupted and still growing in the crypt (note lack of roots). It is unique because of its extremely small size.
Juvenile Gomphothere Jaw & Tooth
This is the front of the lower jaw of a gomphothere (a four tusker). It is the left DP/2 or front first tooth of the baby tooth row. The grove underneath the tooth is the alveolus for the rod-like lower tusk. This tooth is rarely found in the fossil record as it is usually lost. The very unworn nature of the tooth might indicate that this was perhaps embryonic in nature. This tooth is usually lost during the chewing process and falls out of the mouth or is swallowed and eliminated by the gut.
