view of stone 443

Corsi 443, approx. 145 x 73 x 40 mm, © Oxford University Museum of Natural History

OUMNH Number: 443  
Name and quarry location: Broccatello di Maran, from Maran, Verona, Italy  
Geological description: Rosso ammonitico Jurassic pelagic limestone. It is a heavily stylolitised pebbly fossiliferous micrite, either an intraformational conglomerate or a debris-flow.  
Comments: The Verona/Vicenza area, Veneto, Italy is indicated as the provenance by the black number painted on the reverse (see pdf of further information about Verona specimens). In 1899 William Brindley confirmed this stone came from the district of Verona and gave its alternative names, broccatello, rosso broccato, and rosso sanguino. No place called Maran has been located. Perhaps Corsi meant Mazan, but the stone from there described by Jervis (1889) does not match this sample. He records a broccatello from Sant'Ambrogio di Valpolicella. Brindley notes that ‘St Georgio & St Ambrogio all apply to the same locality'. Other examples of this stone seen in the Natural History Museum, London are only labelled as coming from the Verona area.
