Dippy. Dippy is a composite Diplodocus skeleton in Pittsburgh 's Carnegie Museum of Natural History, and the holotype of the species Diplodocus carnegii. It is considered the most famous single dinosaur skeleton in the world, due to the numerous plaster casts donated by Andrew Carnegie to several major museums around the world at the beginning ...
Bucky is one of the few dinosaur fossils found with a furcula; [66] Bucky's furcula was the first one found for the genus Tyrannosaurus. [67] Bucky also has a nearly complete set of gastralia, or belly ribs, and an ulna, or lower arm bone. As of now, 101 bones, or about 34% of Bucky's skeleton, has been discovered and verified. [62]
It was an extremely important find: Hadrosaurus was one of the first nearly complete dinosaur skeletons found (the first was in 1834, in Maidstone, England), and it was clearly a bipedal creature. This was a revolutionary discovery as, until that point, most scientists had believed dinosaurs walked on four feet, like other lizards.
Ott & Larson, 2010. Triceratops (/ traɪˈsɛrətɒps / try-SERR-ə-tops; [1] lit. 'three-horned face') is a genus of chasmosaurine ceratopsian dinosaur that lived during the late Maastrichtian age of the Late Cretaceous period, about 68 to 66 million years ago in what is now western North America. It was one of the last-known non-avian ...
Ceratosaurus / ˌsɛrətoʊˈsɔːrəs / (from Greek κέρας/κέρατος, keras/keratos meaning "horn" and σαῦρος sauros meaning "lizard") was a carnivorous theropod dinosaur that lived in the Late Jurassic period (Kimmeridgian to Tithonian ages). The genus was first described in 1884 by American paleontologist Othniel Charles ...
Furthermore, bones include a number of elements formed in the skin such as gastralia, bony scutes, and spikes. [21] Paleontologists most frequently study the morphology of bones, but also their histology (the inner microstructure up to the cellular level) and chemical composition provided important insights into dinosaur biology. [22]
The function or functions of the horns and frills have been debated for many years. Styracosaurus was a relatively large dinosaur, reaching lengths of 5–5.5 metres (16–18 ft) and weighing about 1.8–2.7 metric tons (2.0–3.0 short tons). It stood about 1.8 meters (5.9 feet) tall. Styracosaurus possessed four short legs and a bulky body.
Dilophosaurus (/ daɪˌloʊfəˈsɔːrəs, - foʊ -/ [ 1 ]dy-LOH-fə-SOR-əs, -foh-) is a genus of theropod dinosaurs that lived in what is now North America during the Early Jurassic, about 186 million years ago. Three skeletons were discovered in northern Arizona in 1940, and the two best preserved were collected in 1942.
