The Kem Kem Group is a lowermost lithostratigraphic unit from the Upper Cretaceous that extends along the border between Algeria and Morocco, in the northern region of Africa. This geological unit has yielded several tetrapod fossils, including a well-represented assemblage of theropod dinosaurs, after more than eight decades of research. Here, we...
A new member of Spinosauridae from the Enciso Group (uppermost Barremian–lower Aptian) from Igea (La Rioja, Spain) is here erected on the
basis of axial, pelvic girdle, and hindlimb elements that exhibit a unique combination of characters. Riojavenatrix lacustris gen. et sp. nov. is one of
the latest Iberian and European spinosaurid taxa. It retain...
The end of the Cretaceous saw the evolution of endemic dinosaur faunas on different landmasses, driven by continental fragmentation. Understanding the evolution of these biogeographic patterns is important for understanding the evolution of Mesozoic ecosystems. However, the faunas of the southern land masses remain understudied relative to the inte...
Among the many valuable uses of the artificial intelligence in the field of museums, it may assist the classification of out-of-context items. This paper deals with the problem of the identification of dinosaur teeth (a type of fossil that is usually found scattered), which can be tackled by means of multivariate algorithms (such as the principal c...

Spinosaurid dinosaurs show a wide geographical and temporal distribution, being present in Gondwanan and Laurasian landmasses, at least, during the Lower Cretaceous and the Cenomanian. European spinosaurids are more diverse than previously thought with five, and probably six, currently recognised genera. The revision of CPI 477, a fragment of a lef...
The discovery of new vertebrate fossil sites with skeletal remains in the Enciso Group of Igea (La Rioja) is showing the relevance of the area to study the palaeobiodiversity of Early Cretaceous vertebrate faunas from the Iberian Peninsula. At Peña Cárcena hill two sedimentary environments have been inferred: a mixed siliciclastic-carbonate lacustr...
Dinosauro teropodoak erregistro fosilean nahiko urriak dira eta askotan aurkitutako fosil bakarrak hortz isolatuak dira. Teropodoen hortzekin, ordea, azterketa paleontologiko anitz egin daitezke, metodologia kualitatibo eta kuantitatibo mota desberdinak erabiliz. Hortzetatik abiatuz, teropodoen biosistematika burutu eta talde honen erregistro fosil...
A total of 227 theropod teeth have so far been recovered from the upper Campanian Laño site (northern Iberian Peninsula). The teeth were studied for their qualitative and quantitative features. From the theropod sample found at Laño, seven morphotypes attributed to five taxa are identified: a medium to large abelisaurid (Arcovenator sp.) and four s...
Theropod behaviour and biodynamics are intriguing questions that paleontology has been trying to resolve for a long time. The lack of extant groups with similar bipedalism has made it hard to answer some of the questions on the matter, yet theoretical biomechanical models have shed some light on the question of how fast theropods could run and what...
The revision and recent discoveries of new theropod material in the Iberian Peninsula shows that spinosaurids were more common and diverse than previously expected with the description of Vallibonavenatrix, the identification of Baryonyx and the probable spinosaurid Camarillasarus. Findings of spinosaurid remains in the Enciso Group (upper Barremia...

Twelve isolated spinosaurid teeth from the Enciso Group of the eastern Cameros Basin (La Rioja, Spain) have been studied. The fossil material has been found in five sites near the town of Igea, where a fluvio-lacustrine system with marine influence was developed during the Barremian-early Aptian. Besides the study of the qualitative and quantitativ...
