European ornithomimosaurs (Dinosauria, Theropoda) : an undetected record

Early Cretaceous ornithomimosaurian theropod dinosaurs have been reported from various localities in Asia, whereas they remain poorly represented and extremely rare in North America, Africa and Europe. So far, the only known European ornithomimosaur is Pelecanimimus from the Barremian of Spain. The recent discovery in southwestern France of a lignitic bone bed in Angeac, which has yielded several hundred ornithomimosaur bones, sheds new light on the ornithomimosaurian fossil record. Based on this new material, we re-evaluate here the systematic position of various isolated theropod bones from the Wealden of England, including historical taxa of uncertain affinities. Based on a unique combination of derived characters, Thecocoelurus and Valdoraptor are linked to the Angeac taxon but are considered to be nomina dubia. Valdoraptor from the Valanginian of West Sussex appears to be the oldest known ornithomimosaur together with the contemporaneous Nqwebasaurus from South Africa. Ornithomimosaurs were a common component of the Early Cretaceous European dinosaur fauna. Their presence in Spain, France and England further strengthens the palaeobiogeographic affinities of the European fossil biota with that of Asia during this period

The Gravettian child mandible from El Castillo Cave (Puente Viesgo, Cantabria, Spain)

Objectives: This article documents an incomplete child's mandible found in H. Obermaier's excavation campaign (in 1912) in El Castillo Cave, Spain. This fossil was assigned to what was then considered a phase of the “Aurignacian-delta”. Materials and Methods: We exhaustively analyzed the original Obermaier documents, with particular attention to those corresponding to the year of the discovery. We extracted a bone sample to radiocarbon date the fossil directly. We also followed established methods to measure, describe and compare the mandible with other human remains. Results: The analysis of Obermaier's documents and new data derived from modern excavations, show that the mandible was discovered in an interior area of the cave. Direct radiocarbon dating yielded a result of 24,720 ± 210 BP and 29,300 – 28,300 cal BP, a date similar to those known for the Gravettian technocomplex both in the El Castillo site and across Europe. The jaw corresponded to a child aged 4–5 years, with modern morphology, but with a certain robustness, especially in the symphyseal region. Comparisons were made with several modern children (Granada, Spitalfields, and Black series) and with immature fossils (European Aurignacian and Gravettian). The few differences between the modern and the fossil children are related to the symphysis and mandibular corpus thickness and height, and to the symphyseal morphology and larger teeth dimensions. Paleoisotopic data for Castillo C correspond with a varied diet. Numerous cutmarks were identified in the midline internal symphyseal region. Discussion and Conclusions: The results agree with those published for other fossils of similar age and chronology (e.g., the mandible of the Lagar Velho child) and show clear differences from the jaws of the young Neanderthals. The interpretation of the original data on the mandible discovery may indicate the destruction of a burial and the displacement, by percolation or by a den, at least of part of the skeleton. The perimortem manipulations in the child's mandible are the first described in the Gravettian world of Western Europe
