| Se da a conocer un nuevo titanosaurio, Pitekunsaurus macayai gen. et sp. nov., procedente de niveles fangolíticos asignados a la Formación Anacleto (Campaniano Inferior - Medio), correspondiente a los depósitos cuspidales del Grupo Neuquén (Cretácico Superior de Cuenca Neuquina). El ejemplar esta representado por basicraneo, frontal izquierdo, un diente, cuatro vértebras cervicales, tres dorsales y cuatro caudales, ulna y escápula derecha, extremo proximal de fémur izquierdo, fragmentos de costillas y restos indeterminados. Pitekunsaurus está caracterizado por las siguientes autapomorfías: (1) procesos basipterigoides ampliamente separados y proyectados paralelamente, (2) presencia en las cervicales anteriores de pequeñas depresiones o fosas longitudinales... |

| El saurópodo Lirainosaurus astibiae Sanz et al., 1999, un grácil titanosaurio de talla media (entre 8 y 10 m de longitud), fue definido a partir de un fragmento de cráneo, dientes y huesos postcraneales procedentes del Cretácico Superior (Campaniano superior a Maastrichtiano inferior) de Laño, en el norte de la Península Ibérica. En este trabajo se describen nuevos restos fósiles que constituyen el primer registro del género Lirainosaurus fuera de su localidad tipo. El nuevo material, procedente de niveles continentales lacustres de la Formación Sierra Perenchiza (Campaniano superior a Maastrichtiano inferior) de la localidad de Chera (provincia de Valencia, este de España), comprende elementos vertebrales, huesos de la cintura escapular y de las... |

| Abstract We describe a dentary of a new titanosaur sauropod, Baalsaurus mansillai, gen. et sp. nov. from the Late Cretaceous of Patagonia, Argentina. The material comes from the Portezuelo Formation, Neuquén Group. Titanosaur sauropods lower jaws are scarce and only nine taxa with dentaries have been described. There are two types of morphology in titanosaur dentaries; “L” shaped or “U” shaped based on the shape, without a phylogenetic issue. In this paper; we recognize a new taxa, Baalsaurus mansillai, represented by an “L” shaped dentary with three apomorphic characters that are not present in other taxa: dentary alveoli with 10 teeth in the anterior ramus, a ventrally and anteriorly inclined symphysis and a wide ventral Meckelian groove surrounded by a... |

| A forelimb of a new sauropod dinosaur (Angolatitan adamastor n. gen. et sp.) from the Late Turonian of Iembe (Bengo Province) represents the first dinosaur discovery in Angola, and is one of the few occurrences of sauropod dinosaurs in sub-Saharan Africa collected with good chronological controls. The marginal marine sediments yielding the specimen are reported to be late Turonian in age and, thus it represents a non-titanosaurian sauropod in sub-Saharan Africa at a time taken to be dominated by titanosaurian forms. Moreover, Angolatitan adamastor is the only basal Somphospondyli known in the Late Cretaceous which implies in the existence of relict forms in Africa. |

| Speed estimations from trackways of Titanopodus mendozensis González Riga and Calvo provide information about the locomotion of titanosaurian sauropods that lived in South America during the Late Cretaceous. Titanopodus ichnites were found at Agua del Choique, a newly discovered track site in the Loncoche Formation, Late Campanian-Early Maastrichtian of Mendoza, Argentina. This speed study follows the hypothesis of dynamic similarity proposed by Alexander. As a refinement of this method, a complementary equation is presented here based on an articulated titanosaurian specimen collected in strata that are regarded as correlative to those that have yielded Titanopodus tracks (Allen Formation, Neuquén Basin). This analysis indicates that hip height can be... |
