Massive salt accumulations, or giants, have formed in highly restricted marine basins throughout geological history, but their impact on biodiversity has been only patchily studied. The giant the Mediterranean Sea as a result of restriction its gateway to Atlantic during Messinian Salinity Crisis (MSC) 5.97 5.33 million years ago. Here, we quantify changes associated with MSC based compilation fossil record. We conclude that 86 endemic species 2006 pre-MSC survived crisis, and present eastward-decreasing richness gradient was established after MSC.

Abstract Haliotis Linnaeus, 1758, a commercially important gastropod, is the only known genus in family Haliotidae (Mollusca, Vetigastropoda, or abalone) worldwide. Its poor Cenozoic record and high intraspecific variability resulted different interpretations of nomenclature, impeding robust species-level taxonomy biogeographic history. Among best-studied forms, three subspecies H. tuberculata 1758 currently inhabit temperate waters Mediterranean eastern Atlantic. New findings Pliocene Tuscany (Italy) are presented here, European revised. On basis multivariate analysis shell morphometrics for first time applied to study fossil abalones, consistent with chronostratigraphic geographic framework, plioetrusca n. sp. introduced volhynica Eichwald, 1829 lamellosoides Sacco, 1897 reinstated as valid species. Some recently described forms from Spain placed synonymy lamellosoides. ovata Michelotti, 1847 proposed ancestral taxon modern , via .
