Otoliths found in situ in fossil fish specimens offer the rare opportunity to relate taxa based on articulated skeletons and isolated otoliths. Here, we describe for the first time otoliths found in situ in two moderately well-preserved articulated skeletons belonging to the extinct lotine fish genus Palaeomolva, and, more particularly, to the species P. tarchanica Daniltshenko, 1947 recently discovered from the middle Miocene (Tarkhanian) of the NW Caucasus in Russia. The otolith-based species Brosme heinrichi Gaemers, 1976 known from a single large specimen from the middle Miocene of the North Sea Basin is now referred as a junior synonym of Palaeomolva tarchanica. The affinities of the known species of Palaeomolva are also briefly discussed.

Reappraisal of the record of the genus Paraisurus (Chondrichthyes; Lamniformes) from the Lower Cretaceous of northern Italy

Isolated and associated teeth of the poorly known lamniform shark Paraisurus macrorhizus are described from the Lower Cretaceous of northern Italy. These fossils, coming from a quarry located in the surroundings of the city of Trento (Trentino-Alto Adige, northeastern Italy), were preliminarily reported in 1927 by D’Erasmo with a problematic age attribution. Based on calcareous nannofossil analyses of the embedding matrix, the fossils are herein assigned to the Albian. The fossil record of Paraisurus is briefly reviewed, and a comparative morphometric analysis is carried out. The PCA analysis on a small data set highlights the existence of two distinct morphotypes that correspond to the two species Paraisurus macrorhizus and P. compressus. This analysis also suggests that P. amudarjensis should be regarded as a junior synonym of P. compressus. Specialised dental features of the genus Paraisurus are also discussed.

New Late Pleistocene leopard fossils from Equi (Massa, Italy) rediscovered in the Manodori Collection, Musei Civici Reggio Emilia, Italy

Seven leopard fossil bones from the important site of Equi (Massa, Italy), stored in the Musei Civici Reggio Emilia (Guido Manodori Galliani Collection), have been studied. These leopard fossils provide new and important data on this elusive and rare felid. The described specimens could represent at least two individuals, one female and one male. This note represents an important enhancement of our knowledge of Late Pleistocene European leopards, especially considering their scarcity in the fossil record.
