OUMNH Number: 337  
Name and quarry location: Lumachella di San Vitale, from the province of Verona, Veneto, Italy  
Geological description: Fossiliferous limestone with a biosparite matrix. Large shells of 'Lithiotis ' bivalves are filled with calcite spar. Stylolites are evident.  
Comments: This is an example of lumachella di San Vitale, a Lower Jurassic limestone containing the elongate sparry calcite-filled shells of the reef-forming bivalve Lithiotis. It is named after the village of San Vitale di Roverè, a source cited by both Pollini (1817, 1825) and Jervis (1889), but was also obtained from other locations in the Anguilla, Squaranto and Pantena valleys of Verona, as well as other places to the north and east. It is not an alabaster, and is not from Cremona.
