Corsi 522, approx. 145 x 73 x 40 mm, © Oxford University Museum of Natural History

OUMNH Number: 522  
Name and quarry location: Pietra felce dell'Elba, pietra paesina, from the island of Elba, Livorno, Tuscany,  
Geological description: Micritic limestone or calcareous marl showing minor fracture constrained iron-staining giving faint paesina effect. It has abundant areas of dendritic manganese oxides.  
Comments: 'Felce' is Italian for fern and alludes to the dendritic manganese oxides in this stone. It may perhaps be from San Martino, in the middle of the island, where Zuccagni-Orlandini (1842) says a compact limestone with markings of beautiful dendrites, abounds.
