Is this fossilized bone or just weathered rock?

I found this in the hills between Lordsburg and Silver City, New Mexico.  Appears to be 90 percent chalcedony or quartz.  Made up of small grains all oriented along the length of the stone. 

Thanks.

Hi, do you see any foramen (holes by wich passes the blood vessels like thé ones on the photo below) on your specimen ?

 Once the smooth exterior of a bone is worn off the identity gets very difficult. This looks like a heavily mineralized very tumbled bone to me. Am assuming the outcropping sediments in the area are suitable for fossils.

Thank you for the reply.  The nearest exposed sedimentary layers are about 2 miles up slope from the location that I found this.  Few fossils found in the location that I was in, but they do exist there.  The area is mainly eroded material from the mountains.

No foramen.  Completely mineralized and highly eroded.
