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.
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.
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 ...
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.
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]
Argentinosaurus is a genus of giant sauropod dinosaur that lived during the Late Cretaceous period in what is now Argentina.Although it is only known from fragmentary remains, Argentinosaurus is one of the largest known land animals of all time, perhaps the largest, measuring 30–35 m (98–115 ft) long and weighing 65–80 t (72–88 short tons).
The main contender for the largest sauropod and the longest known vertebrate is Bruhathkayosaurus matleyi known from now disentereated remains which was upto 40 m (130 ft) in length and 110–130 t (240,000–290,000 lb) in weight. [139] With paleontologist Michael Benton, giving Bruhathkayosaurus a length of 45 metres (148 ft). [140]
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.
