Mario Tozzi (1959-) is a well respected Italian geologist and environmentalist. He has written on various scientific matters and has been a consultant on a number of television programmes. He has also had an asteroid, 11328 mariotozzi, named in his honour.
Tozzi has given his support to Sergio Frau’s theory which locates Atlantis in Sardinia. A number of video clips(a) on the Internet will be of interest to Italian speakers as will Tozzi’s blog on the Italian National Geographic website(b). He has also suggested that if Sardinia was Atlantis, then the Etruscans may have been Sardinians(c).
