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.
Size of three specimens (holotype in green) compared to a human. Deinocheirus is the largest ornithomimosaurian (ostrich dinosaur) discovered; according to the 2014 description, the largest known specimen measured about 11 m (36 ft) long, with an estimated weight of 6.36 t (7.01 short tons). [1]
Plesiosuchus compared to a human. The largest thalattosuchian as well as the largest teleosauroid was unnamed fossil remain from Paja Formation, which may belongs to animal with length of 9.6 m (31 ft), [364] which is as large as outdated length estimate of the Early Cretaceous Machimosaurus rex, more recently estimated at 7.15 m (23.5 ft) in ...
Size comparison of a human to Q. northropi (green) and Q. lawsoni (blue) In 1975, Douglas Lawson compared the wing bones of Quetzalcoatlus northropi 's holotype to equivalent elements in Dsungaripterus and Pteranodon , and suggested that it represented an individual with a wingspan of around 15.5 m (51 ft), though presented alternative ...
Giganotosaurus (/ ˌɡɪɡəˌnoʊtəˈsɔːrəs / GIG-ə-NOH-tə-SOR-əs[2]) is a genus of theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 99.6 to 95 million years ago. The holotype specimen was discovered in the Candeleros Formation of Patagonia in 1993 and is ...
Argentinosaurus (meaning "lizard from Argentina") 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).
Scientists have confirmed the discovery of a new dinosaur species in Australia, one of the largest found in the world, more than a decade after cattle farmers first uncovered bones of the animal.
Size compared with a human. Turiasaurus is believed to be the largest dinosaur ever found in Europe, and is among the largest dinosaurs known. It was originally estimated at over 30 metres (98 ft), possibly around 36–39 metres (118–128 ft) in length and with a weight of 40–48 t (44–53 short tons). [1]
