Mandible excavated from Stainton gravel beds.

My Daughter found this jaw fragment from a new dig in a section of packed gravel 5 metres east of my main dig at Stainton, at the moment i can not identify it. The teeth don't match bovine horse or cervidae that i have or have viewed. The radius i believe could be from the same animal? it apeares to be cervidae?
