Early Miocene herpetofauna from the Ribesalbes-Alcora basin (Castelló, eastern Spain): a first step toward modern herpetofaunas in the Iberian Peninsula The Early Miocene is a key period in the evolution of modern reptile and amphibian faunas, particularly for snakes. However, there are very few studies focused on herpetofauna in Iberian sites of this...
