Corsi 511, approx. 145 x 73 x 40 mm, © Oxford University Museum of Natural History

OUMNH Number: 511  
Name and quarry location: Alberese limestone, from Florence, Tuscany, Italy; and most probably from Valdarno  
Geological description: Micritic limestone or calcareous marl from the Upper Cretaceous Alberese Formation. Fractures are calcite-filled.  
Comments: Only very slight 'paesina' effect (microfracture controlled iron-staining) is evident, and under no circumstance could this stone be called 'verde'. It is an example of Alberese limestone (described in Price, 2007).  
References: Corsi (1825) 127, 130; Price (2007) 99
