A New Sauropod: Tastavinsaurus Sanzi Gen. Et Sp. Nov. from the Early Cretaceous (Aptian) of Spain
TLDR
In the cladistic analysis, Tastavinsaurus is the sister-taxon of the North American Venenosaurus within Titanosauriformes, which includes the Brachiosauridae, Somphospondyli, and Titanosaurusia.
A New Crocodylian from the Late Maastrichtian of Spain: Implications for the Initial Radiation of Crocodyloids
TLDR
The presence of basal crocodyloids at the end of the Cretaceous both in North America and Europe provides new evidence of the faunal exchange via the Thulean Land Bridge during the Maastrichtian.
A new basal rebbachisaurid (Sauropoda, Diplodocoidea) from the Early Cretaceous of the Neuquén Basin; evolution and biogeography of the group
Despite that the origin of rebbachisaurids is retrieved as Late Jurassic is not until the upper Lower Cretaceous that this group can be recognised in the fossil record. The group is geographically
Biochronological implications of the Arvicolidae (Rodentia, Mammalia) from the Lower Pleistocene hominid-bearing level of Trinchera Dolina 6 (TD6, Atapuerca, Spain).
TLDR
The Trinchera Dolina Section is able to calibrate, for the first time, the evolutionary level of important biochronological markers with magnetostratigraphy and it is proposed that a radiation of Microtus s.l., along with the first appearance of primitive S. pusillus, are characteristic of the Late Biharian.
Demandasaurus darwini, a New Rebbachisaurid Sauropod from the Early Cretaceous of the Iberian Peninsula
A new medium-sized rebbachisaurid sauropod from the Castrillo la Reina Formation (Upper Barremian-Lower Aptian) in Burgos Province, Demandasaurus darwini gen. et sp. nov., is described. It is known
La Cantalera: an exceptional window onto the vertebrate biodiversity of the Hauterivian-Barremian transition in the Iberian Peninsula
TLDR
The vertebrate association of La Cantalera displays certain differences with respect to those from lacustrine environments of the Hauterivian-Barremian transition of the Iberian Range, including the absence of Chondrichthyes, the merely token presence of the osteichthyans, the scarcity of chelonians, the presence of exclusively multituberculate mammals, the lower diversity of sauropods and the greater diversity of theropods.
What Iberian dinosaurs reveal about the bridge said to exist between Gondwana and Laurasia in the Early Cretaceous
Some Cretaceous dinosaur taxa with a broad enough record on the continents of the northern hemisphere (Laurasia) or in the southern continents (Gondwana) have been interpreted as Laurasian or
An Unexpected Early Rhabdodontid from Europe (Lower Cretaceous of Salas de los Infantes, Burgos Province, Spain) and a Re-Examination of Basal Iguanodontian Relationships
TLDR
The new ornithopod described here is slender and one of the smallest ever reported, and its dentary and maxillary teeth are unique, remarkably similar to those regarded as having a “rhabdomorphan” affinity.
