Troodon (/ ˈ t r oʊ. ə d ɒ n / TROH-ə-don; Troödon in older sources) is a former wastebasket taxon and a potentially dubious genus of relatively small, bird-like theropod dinosaurs definitively known from the Campanian age of the Late Cretaceous period (about 77 million years ago). It includes at least one species, Troodon formosus, known ...
Life restoration of the juvenile type specimen Size of the holotype, compared to a human.. Mei is a troodontid, a group of small, bird-like, gracile maniraptorans.All troodontids have many unique features of the skull, such as closely spaced teeth in the lower jaw, and large numbers of teeth.
The VLM is the extension of Prandtl's lifting-line theory, [2] where the wing of an aircraft is modeled as an infinite number of Horseshoe vortices. The name was coined by V.M. Falkner in his Aeronautical Research Council paper of 1946. [3] The method has since then been developed and refined further by W.P. Jones, H. Schlichting, G.N. Ward and ...
Troodontidae / t r oʊ. ə ˈ d ɒ n t ɪ d iː / is a clade of bird-like theropod dinosaurs from the Late Jurassic to Late Cretaceous.During most of the 20th century, troodontid fossils were few and incomplete and they have therefore been allied, at various times, with many dinosaurian lineages.
[6] Lovelock expressed that SimEarth's simulation has 'a degree of realism' despite it being "little more than a game", and he expressed that he hadn't seen or been involved in any computer simulations of nature on the scale of SimEarth at the time, noting that many professional climate models at the time didn't take clouds, the ocean, or ...
The deadlift is performed by lifting a weight off of the floor until fully upright. This is a compound exercise that also involves the glutes, lower back, lats, trapezius (upper back), and, to a lesser extent, the quadriceps and the calves. Lifting belts are often used to help support the lower back.
When in 1896 the modern international Olympic Games began, weight lifting was an event at the first Games; and since 1920 weightlifting has been a regular part of the Olympics. [ 5 ] [ 7 ] By 1932 the Olympic competition comprised three lifts, all of which are different ways of lifting a weighted barbell from ground to overhead: namely the ...
That same decade Jack Horner reported the discovery of Troodon nests in Montana. [5] Interest in the life history of Troodon continued in the 1990s with a study of its growth rates based on histological sections of fossils taken from a bonebed in Montana [4] and the apparent pairing of eggs in Troodon nests.
