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.
He estimates a femoral length of 3–3.5 m (9.8–11.5 ft) and a dorsal-sacral length of 7.7–9 m (25–30 ft), much longer than those of the largest titanosaurs. This is larger than Carpenter's estimation, and he stated that the known vertebra could not be plausibly accommodated within a sauropod smaller than 35 m (115 ft).
Among living dinosaurs, the bee hummingbird (Mellisuga helenae) is smallest at 1.9 g (0.067 oz) and 5.5 cm (2.2 in) long. [41] The smallest theropod overall (including avians) is the currently extant bee hummingbird at 6.12 cm long and 2.6g for females, and 5.51 cm long and 3.25g for the males.
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.
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 ...
The longest dinosaur known from reasonable fossils material is probably Argentinosaurus huinculensis with length estimates of 35 metres (115 ft) to 36 metres (118 ft) according to the most recent researches. [23] [24] However the giant Barosaurus specimen BYU 9024 might have been even larger reaching lengths of 45–48 meters (148–157 ft).
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 ...
Amphicoelias. Amphicoelias (/ ˌæmfɪˈsiːliəs /, meaning "biconcave", from the Greek ἀμφί, amphi: "on both sides", and κοῖλος, koilos: "hollow, concave") is a genus of herbivorous sauropod dinosaur that lived approximately 150 million years ago during the Tithonian (Late Jurassic Period) of what is now Colorado, United States.
