[MARMAM] Request for Pontoporia skull and mandibles pictures, photographs and/or papers

Dear fellow MARMAMERS, I write on behalf of Dr. Omar Linares, from the Universidad Simón Bolívar in Caracas, to request for any article, paper, illustration and/or pictures of Pontoporia skull and mandibles. We have reference by Higa et al. (2002), but mandibles are lacking. We thank you very much in advance for your help.   cheers   Jaime
