Two historical collections of Mesozoic ammonites from the Tardàra Mountain (SO Sicily), housed in the “Gaetano Giorgio Gemmellaro” Museum of the University of Palermo, have been revised in this paper. The former and the older collection, studied by Mariano Gemmellaro in the 1919, it is composed of 27 specimens, attributed to 5 genera. All the taxa studied by the Author were referred to the Middle Jurassic, Macrocephalites macrocephalus Zone (early Callovian stage). The second collection, studied by Francesco Bruno in the 1954, consists of 46 specimens attributed to 13 genera. The species identified by Bruno were referred to a chronostratigraphic range spanning from Callovian to Tithonian (M…
The occurrence of the extinct shark genus Sphenodus in the Jurassic of Sicily
2015
During the systematic revision of some historical collections containing Mesozoic ammonites, housed at the "G.G. Gemmellaro" Geological Museum of the Palermo University, a fossil shark’s tooth has been discovered.

The specimen is part of the Mariano Gemmellaro Collection which mainly consists of Middle-Upper Jurassic ammonites coming from Tardàra Mountain, between Menfi and Sambuca di Sicilia (Agrigento Province, Southwestern Sicily). Some of the ammonite specimens were listed, but not illustrated, by M. Gemm…
