FIRST RECORD OF DINOSAURIA (ORNITHISCHIA, HADROSAURIDAE) FOR THE PROVINCE OF LA PAMPA (ARGENTINA) AND ITS... more FIRST RECORD OF DINOSAURIA (ORNITHISCHIA, HADROSAURIDAE) FOR THE PROVINCE OF LA PAMPA (ARGENTINA) AND ITS PALEOGEOGRAPHIC IMPLICATIONS. Dinosaur remains were recorded for the first time in the province of La Pampa, Argentina. They are from the lowest levels of the Allen Formation, Late Campanian-Early Maastrichtian in age. These remains are incomplete cervical, dorsal, sacral and caudal vertebrae, scapula, coracoid, femur and phalanges which may be assigned to Hadrosauridae (Ornithischia, Ornithopoda). The caudal centra are anteriorly hexagonal, condition that has been interpreted as a synapomorphy of Hadrosauridae by many authors. In addition, the presence of dorsal neural arches with diapophyses strongly upward oriented and relatively short neural spines suggests referral of these remains to Hadrosaurinae. Athough some differences with respect to Kritosaurus australis are evident, a more precise systematic assignment is difficult in view of the fragmentary state of these remains. The fossils were found in sandy facies of littoral deposits, influenced by river flow and tides, related to the first Atlantic marine event for the Neuquén Basin. From a paleogeographic standpoint, this new record of Hadrosauridae adds new evidence on the immigration of these dinosaurs from North America toward the end of the Cretaceous. The record from the Allen Formation and equivalent units of northern Patagonia suggests a physical connection between both Americas during the Campanian.

Malarguesaurus florenciae gen. et sp. nov., a new titanosauriform (Dinosauria, Sauropoda) from the Upper Cretaceous of Mendoza, Argentina

by Bernardo González Riga

Malarguesaurus florenciae gen. et sp. nov. is a new and robust somphospondylian titanosauriform (Dinosauria,more Malarguesaurus florenciae gen. et sp. nov. is a new and robust somphospondylian titanosauriform (Dinosauria,
Sauropoda) from the Neuque´n basin, Mendoza Province, Argentina. The specimen comes from Upper Cretaceous strata assigned to the Portezuelo Formation (upper Turonian-lower Coniacian). It includes proximal, middle and distal caudal vertebrae, chevrons, dorsal ribs, and appendicular bones.
Malarguesaurus is characterized by the following association of characters: (1) proximal caudal neural spines vertically directed, with a concave caudal border, and a caudodorsal corner forming a right angle; (2) procoelous-opisthoplatyan proximal and middle caudal vertebrae associated with procoelous distal
caudal centra; and (3) distal caudal neural spines having a concave and depressed dorsal border. A preliminar cladistic analysis placed (Ligabuesaurus+ Malarguesaurus+Phuwiangosaurus)) as a sister
taxon of Titanosauria. Unique among the titanosauriforms, Malarguesaurus has procoelous distal caudal centra associated with procoelous-opisthoplatyan proximal caudals. This discovery is a new evidence of the morphologic diversity of the South American sauropods.

Braincase anatomy of the titanosaurian sauropod Lirainosaurus astibiae from the Late Cretaceous of the Iberian Peninsula

by Verónica Díez

DÍEZ DÍAZ, V., PEREDA SUBERBIOLA, X. and SANZ, J.L. 2011. Braincase anatomy of the sauropod dinosaur Lirainosaurus astibiae (Titanosauria) from the Late Cretaceous of the Iberian Peninsula. Acta Palaeontologica Polonica, 56 (3): 521-533.

Lirainosaurus is the only titanosaurian sauropod described to date from the Late Cretaceous of the Iberian Peninsula.... more Lirainosaurus is the only titanosaurian sauropod described to date from the Late Cretaceous of the Iberian Peninsula. The type of Lirainosaurus astibiae consists of both cranial and postcranial remains that were found as disarticulated elements in the Laño quarry (Treviño, northern Spain). This taxon was diagnosed originally on the basis of vertebral and appendicular autapomorphic traits. The study of a paratypic skull fragment and a second referred specimen provides information about its braincase morphology. Lirainosaurus is regarded as a derived titanosaur on the basis of the complete fusion between the prootic and the exoccipital−opisthotic complex, the position of the cranial foramina, and the shape and orientation of the occipital condyle. The braincase of L. astibiae appears to be diagnostic in the presence of a foramen distally on each basal tubera. The absence of median subcondylar foramina in the basioccipital may be an autopomorphic trait or be due to ontogenetic growth. A comparison with other partial skulls known in Europe suggests a high diversity during the Campanian/Maastrichtian, with at least three different titanosaurian species living in the Ibero−Armorican Island.
