  Paleogeography and diffusion of astriclypeids (Echinoidea Clypeasteroida) from Proto-Mediterranean basins

  ABSTRACT
  In this paper, the authors retrace the geological changes that during the Neogene have modified the paleogeography of the Western Mediterranean up to its current set-up. It is assumed that migration and probably also speciation of the involved astriclypeids (particularly Amphiope L. Agassiz, 1840 and Echinodiscus Leske, 1778) are closely related to those changes.
