Bruhathkayosaurus. Bruhathkayosaurus (/ bruːˌhæθkeɪoʊˈsɔːrəs /; meaning "huge-bodied lizard") is a controversial genus of sauropod dinosaur found in the Kallamedu Formation of India. The fragmentary remains were originally described as a theropod, but it was later determined to be a titanosaurian sauropod.
Patagotitan. Patagotitan is a genus of titanosaurian sauropod dinosaur from the Cerro Barcino Formation in Chubut Province, Patagonia, Argentina. The genus contains a single species known from at least six young adult individuals, Patagotitan mayorum, which was first announced in 2014 and then named in 2017 by José Carballido and colleagues.
One of the longest complete dinosaurs is the 27-metre-long (89 ft) Diplodocus, which was discovered in Wyoming in the United States and displayed in Pittsburgh's Carnegie Natural History Museum in 1907. [26] There were larger dinosaurs, but knowledge of them is based entirely on a small number of fragmentary fossils.
It exceeded 3 m (9.8 ft) in length, and would have weighed in at around 200 kg (440 lb), much larger than any other known mustelid, living or extinct. [154] [155] [156] There were other giant otters, like Siamogale, at around 50 kg (110 lb) [157] and Megalenhydris, which was larger than a modern-day giant river otter. [158]
Macronaria is a clade of sauropod dinosaurs. Macronarians are named after the large diameter of the nasal opening of their skull, known as the external naris, which exceeded the size of the orbit, the skull opening where the eye is located (hence macro - meaning large, and – naria meaning nose). Fossil evidence suggests that macronarian ...
Since then, somewhat larger size estimates have been made, placing Maraapunisaurus at 70 [3] ―120 [4] tons in mass and 35–40 metres (115–131 ft) long, which still makes Maraapunisaurus the third longest animal to have ever lived behind Bruhathkayosaurus and - if one were to count extremely abnormal Barosaurus specimens - BYU 9024, as well ...
This is an incomplete list that briefly describes vertebrates that were extant during the Maastrichtian, a stage of the Late Cretaceous Period which extended from 72.1 to 66 million years before present. This was the last time period in which non-avian dinosaurs, pterosaurs, plesiosaurs, and mosasaurs existed.
Supersaurus (meaning "super lizard") is a genus of diplodocid sauropod dinosaur that lived in North America during the Late Jurassic period. The type species, S. vivianae, was first discovered by Vivian Jones of Delta, Colorado, in the middle Morrison Formation of Colorado in 1972.
