Abstract: A characteristic fauna of dinosaurs and other vertebrates inhabited the end-Cretaceous European archipelago, some of which were dwarves or had other unusual features likely related to their insular habitats. Little is known, however, about the contemporary theropod dinosaurs, as they are represented mostly by teeth or other fragmentary fossils. A new isolated theropod metatarsal II, from the latest Maastrichtian of Spain (within 200,000 years of the mass extinction) may represent a jinfengopterygine troodontid… Show more

“…Nontyrannosauroid coelurosaurs, including maniraptorans, provide further data for comparison. Sharpey's fibers do not appear present in the subarctometatarsalian metatarsals of troodontids sectioned to date (Varricchio 1993;Erickson et al 2007;Sellés et al 2021), nor have they been reported from midshaft thin sections of ornithomimosaur fourth metatarsals (Watanabe et al 2013;Cullen et al 2014). To date the only published, histologically confirmed occurrence of Sharpey's fibers in a theropod metatarsal are those of the distal end of metatarsal II of Xixianykus zhangi, an alvarezsaur which also has an arctometatarsalian pes (Qin et al 2019).…”
