“…These specimens have more recently been assigned to the taxa Astrophocaudia and Cedarosaurus by D'Emic (2013). Indeterminate sauropod fossils have also been reported from the Cloverly Formation (e.g., Ostrom, 1970;Oreska and Carrano, 2013), while in Texas the ichnotaxon Brontopodus birdi has been reported from multiple localities (e.g., Langston, 1974;Pittman, 1989). Additionally, specimens assigned to nodosaurids and Tenontosaurus have been reported from the Paluxy Formation (Langston, 1974;Weishampel et al, 2004).…”

“…have also been recovered from the formation (e.g., Langston, 1974;Weishampel et al, 2004). As noted, both ornithomimosaurs and dromaeosaurs are known from Aptian to Albian deposits in the American west (Ostrom, 1969;Ostrom, 1970;Ostrom 1976;Cifelli, 1997;Cifelli andGardner, 1997, Weishampel et al, 2004;Signac and Mackovicky, 2010;Oreska and Carrano, 2013;Brownstein, 2017a).

“…Analytic comparisons of the Arundel Clay fauna and those of these two units (Table 1 of Appendix 1) show the Arundel fauna is somewhat similar in composition to that of the Ruby Ranch in containing Deinonychus, Tenontosaurus, Acrocanthosaurus, or a similar taxon, a large nodosaurid, and a large titanosauriform (e.g., Leidy, 1865;Marsh, 1888;Kranz, 1996;Weishampel, 2006;Ostrom, 1970;Weishampel et al, 2004;Mori, 2009;Woodruff, 2012;D'Emic and Foreman, 2012;Mannion et al, 2013;Oreska et al, 2013). Notably, ornithomimosaurs and neoceratopsians are absent from the Ruby Ranch Member, though they are present in both the Arundel and the Cloverly Formation along with a large nodosaurid (Sauropelta), Deinonychus, Acrocanthosaurus, Tenontosaurus, ornithomimosaurs, and titanosauriforms (Ostrom, 1969(Ostrom, , 1970(Ostrom, , 1976Kranz, 1996;Chinnery et al, 1998;Makovicky and Sues, 1998;Gignac and Makovicky, 2010;Woodruff, 2012;Oreska et al, 2013;Farke et al, 2014;Brownstein, 2017a).…”

Additional fossils assigned to Sauropelta have been recovered from middle Cedar Mountain Formation (Jensen, 1984;Weishampel et al, 2004).…”

The biogeography and ecology of the Cretaceous non-avian dinosaurs of Appalachia

The Cenomanian to Maastrichtian of the Late Cretaceous saw the flooding of the interior of North America by the Western Interior Seaway, which created the eastern landmass of Appalachia and the western landmass of Laramidia. Though Appalachian dinosaur faunas are poorly known, they are nevertheless important for understanding Cretaceous dinosaur paleobiogeography and ecology. In order to better track the vicariance of eastern and western North American dinosaur faunas over the duration of the Cretaceous, the former were compared with the latter from the Aptian to Maastrichtian Stages of the Late Cretaceous using several similarity indices. The data gathered from biogeographic similarity indices suggest that an almost completely homogenous North American dinosaur fauna found in the Early Cretaceous experienced significant vicariance, splitting into a Laramidian fauna differentiated by the presence of ceratopsids, pachycephalosaurids, saurolophids, lambeosaurines, ankylosaurids, therizinosaurids, and troodontids and an Appalachian fauna characterized by the lack of the aforementioned groups and the presence of non-hadrosaurid hadrosauroids, massive hadrosauroids, basal hadrosaurids, leptoceratopsians, "intermediate"-grade tyrannosauroids, and nodosaurids between the Cenomanian and Campanian, with these two faunas later experiencing limited dispersal after the disappearance of the Western Interior Seaway from the American Interior during the Maastrichtian. Dinosaur provincialism and ecology on Appalachia are also investigated and discussed.
