“…Other isolated finds were also made near Soria around the same time ( Lapparent et al 1957 ). In the last thirty years, systematic excavations at a large number of sites distributed across the Iberian Peninsula, mainly in the southern Pyrenees (provinces of Huesca, Lleida, and Barcelona), the Iberian Range (mainly Burgos, Cuenca, Segovia, and Valencia), and the Basque-Cantabrian Region (Condado de Treviño within Alava), have yielded abundant fossils of dinosaurs and other continental vertebrates ( Pereda-Suberbiola et al 1999 b; Pereda-Suberbiola 2006 ; López-Martínez et al 2001 ; Ortega et al 2006 and references therein; Figs 8 , 9 ).…”

The Late Cretaceous was a time of tremendous global change, as the final stages of the Age of Dinosaurs were shaped by climate and sea level fluctuations and witness to marked paleogeographic and faunal changes, before the end-Cretaceous bolide impact. The terrestrial fossil record of Late Cretaceous Europe is becoming increasingly better understood, based largely on intensive fieldwork over the past two decades, promising new insights into latest Cretaceous faunal evolution. We review the terrestrial Late Cretaceous record from Europe and discuss its importance for understanding the paleogeography, ecology, evolution, and extinction of land-dwelling vertebrates. We review the major Late Cretaceous faunas from Austria, Hungary, France, Spain, Portugal, and Romania, as well as more fragmentary records from elsewhere in Europe. We discuss the paleogeographic background and history of assembly of these faunas, and argue that they are comprised of an endemic ‘core’ supplemented with various immigration waves. These faunas lived on an island archipelago, and we describe how this insular setting led to ecological peculiarities such as low diversity, a preponderance of primitive taxa, and marked changes in morphology (particularly body size dwarfing). We conclude by discussing the importance of the European record in understanding the end-Cretaceous extinction and show that there is no clear evidence that dinosaurs or other groups were undergoing long-term declines in Europe prior to the bolide impact.

“…The above-mentioned features appear to be novelties, probably due to the poorly known record of thyreophorans in the Southern Hemisphere 4,[11][12][13][14][15] . Moreover, the mixture of plesiomorphic, stegosaurian and ankylosaurian www.nature.com/scientificreports/ characters of Jakapil may also suggest a basal phylogenetic placement (outside Eurypoda) for this taxon (contra 6 ).…”

“…Scutellosaurus is a small (1.5-2 m body length) and slender thyreophoran with a bipedal life style 9 whereas the larger Scelidosaurus (4.5 m body length) is thought to be facultatively bipedal 10 (body length has not been confidently estimated for Emausaurus). Both Scutellosaurus and Scelidosaurus represent part of the early locomotor diversity of early ornithischians, with obligate quadrupedality evolving in later and larger ankylosaurs and stegosaurs 9 .The fossil record of Thyreophora is mainly known from the northern hemisphere, and its presence in the Gondwanan continents remains poorly known, with only a few ankylosaurian or stegosaurian species, and several indeterminate materials 4,[11][12][13][14][15] .We present here a new thyreophoran genus and species from the Late Cretaceous of South America. The remains were found near the locality of Cerro Policía within the 'La Buitrera Paleontological Area' (LBPA), close to the E. Ramos Mexía Dam, in North Patagonia, Río Negro Province, Argentina.…”

The early evolution of thyreophoran dinosaurs is thought to have occurred primarily in northern continents since most evidence comes from the Lower and Middle Jurassic of Europe and North America. The diversification into stegosaurs and ankylosaurs is obscured by a patchy fossil record comprising only a handful of fragmentary fossils, most with uncertain phylogenetic affinities. Here we report the discovery of a new armoured dinosaur from the early Late Cretaceous of Argentina, recovered phylogenetically using various datasets either as a basal thyreophoran or a stem ankylosaur, closely related to Scelidosaurus. It bears unusual anatomical features showing that several traits traditionally associated with the heavy Cretaceous thyreophorans did not occur universally. Jakapil kaniukura gen. et sp. nov. is the first definitive thyreophoran species from the Argentinian Patagonia. Unlike most thyreophorans, it seems to show a bipedal stance, as in Scutellosaurus. Jakapil also shows that early thyreophorans had a much broader geographic distribution than previously thought. It is a member of an ancient basal thyreophoran lineage that survived until the Late Cretaceous in South America.

“…Latter examination of these bones led others to doubt its identification (Chatterjee and Rudra, 1996;Wilson et al, 2011), or regard it as nomen dubium (Maidment et al, 2008) or ?Stegosauria indet. (Pereda-Suberbiola et al, 2015).…”
