A new species of Geochelone (Testudinata: Testudinidae) from the Pleistocene of Florida (U.S.A.)

  • Walter AUFFENBERG

Abstract:

A new species of fossil land tortoise, Geochelone mlynarskii, is described from the Coleman IIA, late Irvingtonian mammal age, middle Pleistocene, central Florida, U.S.A. It is clearly a member of the turgida-complex (sensu Aufeenberg , 1963). The new species differs from its closest relative Geochelone incisa (Hay) (Rancholabrean faunal age, Florida) in its significantly smaller adult size and in certain measurements and architectural details of especially the plastron.
