This study deals with the herpetofaunal fossil and subfossil remains from the Cadet 2 site (Marie-Galante, Guadeloupean Archipelago). This study provides new data concerning the herpetofaunal community since the Late Pleistocene by revealing the early local occurrence of some taxa (Eleutherodactylus sp., cf. Sphaerodactylus sp., Ameiva sp., cf. Capitellum mariagalantae, Anolis cf. ferreus, cf. Antillotyphlops sp., cf. Alsophis sp. and Colubroidea sp. 1) and possible Pleistocene extinctions (Boa sp. and Colubroidea sp. 2). Moreover, the first metric data for fossil Marie-Galante anoles show clear size stability throughout time. As regards the evolution of the island herpetofaunal biodiversity, our work points to the long-term stability of the fauna before human colonization and subsequently to the marked impact of human-caused environmental disturbances during colonial but also Pre-Columbian periods.
