Hyracodon Crossed Jaw on Matrix, Fossil, South Dakaota, Oligocene, R1079

 
  
  

   
    Type:
   
   Fossil partial jaw from
   
    Hyracodon nebraskensis
   
   .  This jaw is a cris-cross flipped mandible that has teeth pointing in opposite directions.  I don't usually see them jumbled like this.  It has no restoration and I prepped it with the matrix intact.  Will make a nice addition to the collection.
