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).
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.
The largest found so far is estimated to have been 30.5 cm (12.0 in) long including the root when the animal was alive, making it the largest tooth of any carnivorous dinosaur yet found. [54] The lower jaw was robust. Its front dentary bone bore thirteen teeth. Behind the tooth row, the lower jaw became notably taller. [51]
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).
The fifth set of tracks, alternatively, were made by a carnivore called Megalosaurus, reported Reuters. Megalosaurus was a theropod, a class of dinosaurs that were ancestrally carnivorous, bipedal ...
Recent size estimates in 2023 have placed this sauropod reaching lengths of up to 44 m (144 ft) long and a colossal weight range of around 110 000 – 170 000 kg (240 000 – 370 000 lb), if these upper estimates up true, Bruhathkayosaurus would have rivaled the blue whale and Perucetus colossus as one of the largest animals to have ever ...
“I had found buffalo and cow bones in the past and knew these were definitely bigger,” Jessin, 12, told The Post of the discovered leg bone. “It was pretty cool.”
The UK's biggest ever dinosaur trackway site has been discovered in a quarry in Oxfordshire. About 200 huge footprints, which were made 166 million years ago, criss-cross the limestone floor.
