  2. Paleontology in Tennessee - Wikipedia

    en.wikipedia.org/wiki/Paleontology_in_Tennessee

    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]

  3. Dacentrurus - Wikipedia

    en.wikipedia.org/wiki/Dacentrurus

    Dacentrurus (meaning "tail full of points"), originally known as Omosaurus, is a genus of stegosaurian dinosaur from the Late Jurassic and perhaps Early Cretaceous (154 - 140 mya) of Europe. Its type species, Omosaurus armatus, was named in 1875, based on a skeleton found in a clay pit in the Kimmeridge Clay in Swindon, England.

  4. Tyrannosaurus - Wikipedia

    Studies by Dececchi et al., compared the leg proportions, body mass, and the gaits of more than 70 species of theropod dinosaurs including Tyrannosaurus and its relatives. The research team then applied a variety of methods to estimate each dinosaur's top speed when running as well as how much energy each dinosaur expended while moving at more ...

    Additionally, a 2020 study indicates that tyrannosaurids were exceptionally efficient walkers. Studies by Dececchi et al., compared the leg proportions, body mass, and the gaits of more than 70 species of theropod dinosaurs including tyrannosaurids. The research team then applied a variety of methods to estimate each dinosaur's top speed when ...

    Its brain-to-body mass ratio is one of the highest of any non-avian dinosaur Stephanosaurus: 1914 Dinosaur Park Formation (Late Cretaceous, Campanian) Canada ( Alberta) Poorly known Stokesosaurus: 1974 Morrison Formation (Late Jurassic, Kimmeridgian? to Tithonian) United States ( South Dakota?

    A graph showing the hypothesized growth curves (body mass versus age) of four tyrannosaurids. Daspletosaurus is shown in green, based on Erickson et al., 2004. Paleontologist Gregory Erickson and colleagues have studied the growth and life history of tyrannosaurids. Analysis of bone histology can determine the age of a specimen when it died ...

  8. Dinosaur size - Wikipedia

    en.wikipedia.org/wiki/Dinosaur_size

    Predatory theropod dinosaurs, which occupied most terrestrial carnivore niches during the Mesozoic, most often fall into the 100–1,000 kg (220–2,200 lb) category when sorted by estimated weight into categories based on order of magnitude, whereas recent predatory carnivoran mammals peak in the range of 10–100 kg (22–220 lb).

  9. Physiology of dinosaurs - Wikipedia

    en.wikipedia.org/wiki/Physiology_of_dinosaurs

    A graph showing the hypothesized growth curves (body mass versus age) of four tyrannosaurids. Tyrannosaurus rex is drawn in black. Based on Erickson et al. 2004. Tyrannosaurus rex showed a "teenage growth spurt": [56] [57] ½ ton at age 10; very rapid growth to around 2 tons in the mid-teens (about ½ ton per year). negligible growth after the ...
