EHINOCEEOTID, indet. 

 A fragment of an upper rhinoceros cheek-tooth from locality 3037 

 represents an indeterminate form. It is possible that future studies 

 with the use of exceptionally good material for comparison may make 

 possible an approximate determination of this tooth. For the present- 

 it is desirable to record the occurrence of rhinocerotid remains at this 

 locality.
