Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive titanosaur Argentinosaurus huinculensis, which is the largest dinosaur known from uncontroversial and relatively substantial evidence, estimated to have been 70–80 t (77–88 short tons) and 36 m (118 ft) long.
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).
Gargantuavisis the largest known bird of the Mesozoic, a size ranging between the cassowaryand the ostrich, and a mass of 140 kg (310 lb) like modern ostriches.[491] In 2019 specimens MDE A-08 and IVPP-V12325 were measured at 1.8 m (5 ft 11 in) in length, 1.3 m (4 ft 3 in) in hip height, and 120 kg (260 lb) in weight.
The discussion of which theropod was the largest was revived in the 1990s by new discoveries in Africa and South America. [1] In their original description, Coria and Salgado considered Giganotosaurus at least the largest theropod dinosaur from the southern hemisphere, and perhaps the largest in the world.
Sauropods are one of the most recognizable groups of dinosaurs, and have become a fixture in popular culture due to their impressive size. Complete sauropod fossil finds are extremely rare. Many species, especially the largest, are known only from isolated and disarticulated bones. Many near-complete specimens lack heads, tail tips and limbs.
Titanosauria have the largest range of body size of any sauropod clade, and includes both the largest known sauropods and some of the smallest. [25] One of the largest titanosaurs, Patagotitan, had a body mass estimated to be 69 tonnes (76 tons), whereas one of the smallest, Magyarosaurus, had a body mass of approximately 900 kilograms (2,000 lb).
Titanoboa (/ ˌtaɪtənəˈboʊə /; lit. 'titanic boa') is an extinct genus of giant boid (the family that includes all boas and anacondas) snake that lived during the middle and late Paleocene. Titanoboa was first discovered in the early 2000s by the Smithsonian Tropical Research Institute who, along with students from the University of ...
Scotty (dinosaur) Scotty is the nickname for the Tyrannosaurus rex fossil, catalogued as RSM P2523.8, that was discovered in Saskatchewan, Canada in 1991. The fossilised remains were painstakingly removed, almost completely by hand, over two decades from the rock in which they were embedded. [1]
