view of stone 55

Corsi 55, approx. 145 x 73 x 40 mm, © Oxford University Museum of Natural History

OUMNH Number: 55  
Name and quarry location: Marmo carnagione, marmo cannellino chiaro, probably from the Umbria or Marches regions of the Apennines, Italy  
Geological description: Pelagic limestone from the Scaglia Rossa Formation (Upper Cretaceous-Eocene), mottled grey with a rich fauna of foraminifera and other plankton.  
Comments: Corsi did not give a quarry location for this pink limestone, but it is almost certainly that quarried in the Apennines and long used for building and decoration in that area. For example, the stone from Monte Subasio near Assisi was used strikingly in the decoration of the Basilica of Sant Clara in Assisi. The rectangular marking on the specimen is a residue of glue from a label and demonstrates how very porous this stone is. It does not readily take a high polish.
