OUMNH Number: 336  
Name and quarry location: Lumachella di San Vitale, mischio di Mizolle, from Mizolle, Val Pantena, Verona, Veneto, Italy  
Geological description: Limestone; a fossiliferous micrite/biosparite with debris of the the lower Jurassic reef-forming 'Lithiotis' bivalve.  
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. The term mischio means 'mixed', an allusion to its different colours, but it is not an alabaster.
