• ref 29608: "During the 2001 field survey, local collectors reported the fortuitous finding on the surface, in the neighbourhood of the village of Ambondromamy (Fig. 3), of two cranial fragments with well preserved teeth still in place, belonging to two different kinds of fossil reptiles. After several events, the two cranial fragments were acquired in Europe by Gilles Emringer and Francois Escuillié of the Eldoniasociety of Gannat, France, with the purpose to make them available for scientific description. The first specimen, a sauropod mandibular fragment now housed in the Toulouse Natural History Museum, was studied by E. Buffetaut (Buffetaut, 2005). G. Pasini was able to see the second specimen in June 2003 and to recognize that the teeth still implanted in the bone were identical to the teeth he had collected in the field in the meantime, during the prospecting activity in April 2003. Therefore the Museo Civico di Storia Naturale di Milano acquired the specimen, in order to study it together with the isolated teeth collected around the same area."
