• If compared with the amphibians and reptiles currently living near the Venetian Lagoon (see Sindaco et al. 2006; Bonato et al. 2007; and Sillero et al. 2014), the assemblage of the Tenuta Zuccarello well clearly lacks various taxa, notably anurans of the Bufotes viridis complex and the genus Pelophylax as well as wall lizards of the genus Podarcis. It is not easy to explain the absence of common taxa such as these ones in terms of environmental features of the area in the past, taking also into account the wide range of habitats that they inhabits today. Moreover, it has to be noted that at least some of these taxa has been found in nearby sites of similar age (e.g. green frogs in Lova di Campagna Lupia and Oderzo; Delfino et al. 2008). Their absence from Tenuta Zuccarello is therefore puzzling. Of course, as far as small lacertid lizards like Podarcis are concerned, they might be represented, though unrecognised, among the small lacertid remains identified only at family level. On the other hand, almost all of the taxa found in the Roman well are still represented near the Lagoon. The only exception is Bombina, which currently lives in most of the Veneto region (Bombina variegata; Bonato et al. 2007; Sillero et al. 2014), but not near the Lagoon. The other two fossil occurrences of the genus in Veneto, both Early Pleistocene in age, are located in the Verona province (Delfino et al. 2008; Villa et al. 2018), that is within the current range of B. variegata. Tenuta Zuccarello represents therefore the first occurrence of Bombina outside its current range.

• The well has an average diameter of 80 cm and was filled by clayey-silty and clayey-sandy sediments. Two different filling sequences were recognised, but they are considered approximately coeval. A rather large number of faunal remains were found in the well, representing both invertebrates (molluscs) and vertebrates (amphibians, reptiles, birds, and small mammals).
