... Fossils of large ornithopods were initially reported in the first half of the 19th century from the findings of Sussex (England), that were described by Gideon Mantell (Mantell, 1825). Since then, these dinosaurs have been of particular interest (e.g., Cope, 1869;Huxley, 1870;Dollo, 1905;Gilmore, 1909;Norman, 1980Norman, , 1986Norman, , 2011Norman, , 2014Sarjeant et al., 1998;Carpenter and Wilson, 2008;Maidment et al., 2013;Maidment and Barrett, 2014), likely because they are widely represented by tracks and bones in the Lower Cretaceous fossil record, particularly those of non-hadrosaurid styracosternans in Europe (e.g., Mantell, 1825;Hooley, 1925;Lapparent and Zbyszewski, 1957;Antunes, 1976;Paul, 2008;Carpenter and Ishida, 2010;Norman, 2010Norman, , 2012Norman, , 2015Gasulla et al., 2014Gasulla et al., , 2015Gasulla et al., , 2022Figueiredo et al., 2015Figueiredo et al., , 2022bFigueiredo et al., , 2023Verdú et al., 2015Verdú et al., , 2017Verdú et al., , 2018Verdú et al., , 2019Verdú et al., , 2021Fuentes-Vidarte et al., 2016;Shillito and Davies, 2019;Lockwood et al., 2021; https://doi.org/10.1016/j.palwor.2024.03.005 1871-174X/Ó 2024 Elsevier B.V. and Nanjing Institute of Geology and Palaeontology, CAS.
