The snout and lower jaw are extremely robust, short, and high and only bear a few large teeth with serrated edges (resembling those of some terrestrial carnivorous archosaurs). This unusual morphology contrasts with the long and gracile snout and lower jaws bearing numerous teeth, which are present in the closest relatives of D. andiniensis (and interpreted as indicating feeding on small fish or mollusks). Thus, the morphological diversity of pelagic marine crocodyliforms was wider than had been thought.<\/jats:p>","DOI":"10.1126\/science.1120803","type":"journal-article","created":{"date-parts":[[2005,11,11]],"date-time":"2005-11-11T01:43:48Z","timestamp":1131673428000},"page":"70-73","source":"Crossref","is-referenced-by-count":81,"title":["An Unusual Marine Crocodyliform from the Jurassic-Cretaceous Boundary of Patagonia"],"prefix":"10.1126","volume":"311","author":[{"given":"Zulma","family":"Gasparini","sequence":"first","affiliation":[{"name":"Consejo Nacional Investigaciones Cienti\u0301ficas y Te\u0301cnicas (CONICET), Departamento de Paleontologi\u0301a de Vertebrados, Facultad de Ciencias Naturales y Museo, Universidad Nacional de La Plata, Paseo del Bosque s\/n, 1900 La Plata, Argentina."},{"name":"Mathematical Biosciences Institute, The Ohio State University, 231 West 18th Avenue, Columbus, OH 43210, USA."},{"name":"CONICET, Centro de Investigaciones Geolo\u0301gicas, Facultad de Ciencias Naturales y Museo, Universidad Nacional de La Plata, Calle 1, 644, 1900 La Plata, Argentina."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diego","family":"Pol","sequence":"additional","affiliation":[{"name":"Consejo Nacional Investigaciones Cienti\u0301ficas y Te\u0301cnicas (CONICET), Departamento de Paleontologi\u0301a de Vertebrados, Facultad de Ciencias Naturales y Museo, Universidad Nacional de La Plata, Paseo del Bosque s\/n, 1900 La Plata, Argentina."},{"name":"Mathematical Biosciences Institute, The Ohio State University, 231 West 18th Avenue, Columbus, OH 43210, USA."},{"name":"CONICET, Centro de Investigaciones Geolo\u0301gicas, Facultad de Ciencias Naturales y Museo, Universidad Nacional de La Plata, Calle 1, 644, 1900 La Plata, Argentina."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis A.","family":"Spalletti","sequence":"additional","affiliation":[{"name":"Consejo Nacional Investigaciones Cienti\u0301ficas y Te\u0301cnicas (CONICET), Departamento de Paleontologi\u0301a de Vertebrados, Facultad de Ciencias Naturales y Museo, Universidad Nacional de La Plata, Paseo del Bosque s\/n, 1900 La Plata, Argentina."},{"name":"Mathematical Biosciences Institute, The Ohio State University, 231 West 18th Avenue, Columbus, OH 43210, USA."},{"name":"CONICET, Centro de Investigaciones Geolo\u0301gicas, Facultad de Ciencias Naturales y Museo, Universidad Nacional de La Plata, Calle 1, 644, 1900 La Plata, Argentina."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"221","reference":[{"key":"e_1_3_1_2_2","first-page":"263","year":"1973","unstructured":"W.
