Palaeopython
Palaeopython is an extinct genus of snake from the Eocene of Europe. The genus has been used to refer to large Western and Central European snake vertebrae from the Eocene. P. cadurcensis and P. filholii originate from France; P. ceciliensis originates from Germany; and P. helveticus originates from Switzerland. A species known from multiple well-preserved specimens found in the Messel Pit of Germany, P. fischeri, was named by Stephan Schaal in 2004, but examination of the genus showed that it represented a distinct lineage; it was renamed Eoconstrictor fischeri in 2020. An additional species, P. sardus, was described in 1901 by Alessandro Portis from the Middle Miocene of Monte Albu. However, a reevaluation of the holotype specimen of this species revealed it to actually belong to an indeterminate acanthomorph fish.
