OUMNH Number: 207  
Name and quarry location: Breccia de' Gherardeschi, perhaps from Tuscany, Italy  
Geological description: Limestone. A bio-pel micrite crowded with small intraclasts and shell debris. Anastomosing white material is calcite-replaced scleractinian coral. Note the extensive development of stylolites.  
Comments: It is not clear why Corsi associated the stone with the Gherardesci. They were a prominent family in the Republic of Pisa from the 11th to the 13th centuries, and there is a Gherardesca Chapel in the church of San Francesco in Pisa, where perhaps this stone is used. The quarry location may be in Tuscany, but is not confirmed.
