This is a list of dinosaurs whose remains have been recovered from Appalachia. During the Late Cretaceous period, the Western Interior Seaway divided the continent of North America into two landmasses; one in the west named Laramidia and Appalachia in the east. Since they were separated from each other, the dinosaur faunas on each of them were ...
Stromatoporoids lived in Tennessee during the Ordovician. [2] Ordovician trilobites were preserved in Rutherford County. [4] Silurian Tennessee remained covered by seawater. [1] The Silurian fauna of Tennessee included brachiopods, bryozoans, crinoids, and gastropods. [5] Tennessee was still submerged into the ensuing Devonian period. [1]
Restoration. The juvenile specimen of Appalachiosaurus measures approximately 6.5 m (21 ft) long and 623 kg (1,373 lb). [1] [4] So far, it is only known from partial remains, including parts of the skull and lower jaw, as well as several vertebrae, parts of the pelvis, and most of both legs.
Dryptosaurus (/ ˌ d r ɪ p t oʊ ˈ s ɔːr ə s / DRIP-toh-SOR-əs) is a genus of eutyrannosaurian theropod dinosaur that lived on the island continent of Appalachia approximately 67.6 million years ago during the end of the Maastrichtian age of the Late Cretaceous period.
Borealopelta was a large dinosaur, measuring 5.5 metres (18 ft) long and weighing 1.3 metric tons (1.4 short tons). The Suncor specimen is remarkable for its three-dimensional preservation of a large, articulated dinosaur complete with soft tissue.
Fossils of Tawa-like dinosaurs have also been found in South America, which has important indications about paleogeography. During the Early Jurassic Period, dinosaurs such as Dilophosaurus, Anchisaurus, Coelophysis (formerly known as Megapnosaurus), and the early thyreophoran Scutellosaurus lived in North America.
Paleoecological analysis indicates that Sauroposeidon lived on the shores of the Gulf of Mexico, in a river delta. Extrapolations based on the more completely known Brachiosaurus indicate that the head of Sauroposeidon could reach 16.5–18 m (54–59 ft) in height with its neck extended, which would make it one of the tallest known dinosaurs ...
Skulls of the three species compared: P. perotorum (with inaccurate epiparietal placement), P. canadensis, and P. lakustai Pachyrhinosaurus canadensis, was described in 1950 by Charles Mortram Sternberg based on the holotype incomplete skull NMC 8867, and the paratype incomplete skull NMC 8866, which included the anterior part of the skull but was lacking the right lower mandible, and the "beak".
