A male of the extinct leaf-beetle species Calomicrus eocenicus embedded in Baltic amber is found and compared with an earlier known female. The beetle genitalia are illustrated in detail using X-ray microtomography. The male is smaller than female and has a modified last abdominal segment. The extinct species (about 40 million years old) possesses typical sexual characters which are similar to the characters of extant beetles within the group.

New fossil species of skin beetles (Dermestidae) from two bioinclusions in Eocene ambers (Baltic and Rovno) are described and compared with extinct and extant congeners. The affinity of the Rovno and Baltic amber varieties is briefly reviewed. The checklist of the described beetles (57 species) from Rovno amber is compiled and presented for the first time.

Peltochelys duchastelii is an enigmatic fossil turtle from the Early Cretaceous of Bernissart, Belgium. Here we provide an alternative interpretation of the morphology of this turtle, which suggests for the first time relationships with paracryptodires, a now extinct group of turtles known from coeval deposits throughout western Europe and North America.

We describe a new species and genus of weevils, Baltacalles triumurbium, from the Eocene amber of the Sambia Peninsula (Kaliningrad Region, Russia). The new fossil represents the first Eocene representative of the group. In addition to the taxonomic work, the locally distinct deposits of Baltic amber in the Kaliningrad Region are listed, discussed, photographed and mapped. The importance of the possible exact labeling of the amber material is underlined.
