[Bonetools] unusual fish bones- worked?

[h13017cho at helka.iif.hu]

Dear colleagues,
    
    A friend and colleague from Israel, Irit Zohar,  has written about some 
veryunusual fish bones from a 800,000 year old archaeological site in the 
Jordan Valley.
   She says she hasnever seen marks like this on the bones and that they 
are unusually polished looking -  even for fish bone.  I am sending along the 
pictures she sent. they are not the best but for the moment they will have to 
do. Any ideas - they look like nothing very special to me but then I am not 
used to looking at tools from such ancient contexts?  Her e-mail is:
 zoharir at post.tau.ac.il

Best alice
