Biological hard tissues are a rich source of design concepts for the generation of advanced materials. They represent the most important library of information on the evolution of life and its environmental conditions. Organisms produce soft and hard tissues in a bottom-up process, a construction principle that is intrinsic to biologically secreted materials. This process emerged early on in the geological record, with the ons...

The population dynamics of the fossil micromorphic brachiopods from shallow‐water Miocene deposits (calcareous clays to hard bottom of reef cavities) of the Roztocze Hills, south‐eastern Poland were studied by means of size‐frequency distributions. The following four species, which all also occur in the Recent Mediterranean, were used for the study: Megathiris detruncata (Gmelin), Argyrotheca cuneata (Risso), A. cordata (Risso...
