OUMNH Number: 910  
Name and quarry location: perhaps breccia corallina, from Verzirhan, Bilecik,Turkey  
Geological description: Heavily sheared and recrystallised limestone breccia, almost entirely altered to fine-grained marble.  
Comments: We have been told this is a variety of breccia corallina, quarried near the village of Vezirhan in Bilecik, Turkey close to a tributary of the River Sakarya. In Roman times the area was Bythinia and the river was called Sagarius. No.404 is a very typical example.
