En Afrique du Nord, peu de matériel fossile a été décrit et attribué à des représentants des familles Agamidae et Chamaeleonidae. Le site d’Ifri n’Ammar a livré des restes (fragments de crânes, dentaires, maxillaires et vertèbres) qui ont été attribués à Agama bibronii (l’agame de Bibron; Agamidae) et à Chamaeleo chamaeleon (le caméléon commun ; Chamaeleonidae). Du point de vue chronologique, les restes de ces deux espèces ont été récoltés dans des niveaux se situant entre 83 ± 6 ka et 171 ± 12 ka pour Agama bibronii et entre 83 ± 6 ka et 130 ± 8 ka pour Chamaeleo chamaeleon. Les affinités bioclimatiques de ces deux espèces renseignent sur la présence aux alentours d’Ifri n’Ammar d’un milieu rocheux avec persistance de zones arborées, notamment durant la période comprise entre 83 ± 6 ka et 130 ± 8 ka, corrélée au stade isotopique 5. L’étude paléontologique entreprise sur les restes fossiles de ces deux espèces apporte une contribution importante à la connaissance des Agamidae et des Chamaeleonidae pléistocènes du Maroc.
In North Africa, few fossil materials have been described and attributed to representatives of the Agamidae and Chamaeleonidae families. The Ifri n’Ammar site yielded remains (fragments of skulls, dentaries, maxillae and vertebrae) which have been attributed to Agama bibronii (Bibron’s agame ; Agamidae) and to Chamaeleo chamaeleon (common chameleon; Chamaeleonidae). Chronologically, the remains of these two species were collected in levels dated between 83 ± 6 ka and 171 ± 12 ka for Agama bibronii and between 83 ± 6 ka and 130 ± 8 ka for Chamaeleo chamaeleon. The bioclimatic affinities of these two species provide information on the presence around Ifri n’Ammar of a rocky environment with persistence of wooded areas, in particular during the period between 83 ± 6 ka and 130 ± 8 ka, correlated with Marine Isotopic Stage 5. The paleontological study undertaken on the fossil remains of these two species gives an important contribution to the knowledge of the Pleistocene Agamidae and Chamaeleonidae of Morocco.
