Supersaurus was likely the world's longest dinosaur — around 137 feet, on average, from nose to tail. Scientists crowned the world's longest dinosaur — a Supersaurus longer than 3 school buses ...
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).
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.
The largest freshwater turtle of all time was the Miocene podocnemid Stupendemys, with an estimated parasagittal carapace length of 2.86 m (9 ft 5 in) and weight of up to 1,145 kg (2,524 lb). [296] Carbonemys cofrinii from the same family had a shell that measured about 1.72 m (5 ft 8 in), [ 297 ] [ 298 ] [ 299 ] complete shell was estimated at ...
Dinosaur fans who responded to the museum's request for input overwhelmingly chose to call the Natural History Museum's new 70-foot-long sauropod 'Gnatalie.'
It is among the longest dinosaurs ever discovered, with the three known specimens reaching 33–40 meters (108–131 ft) in length, with the largest individual possibly exceeding 40 meters (130 ft) in size. [4] [5] Mass estimates for the WDC and BYU specimens tend to be around 35–44 metric tons (39–49 short tons) in body mass. [5]
The previous record for the smallest non-avian dinosaur egg, according to Guinness World Records, measures 45-by-20 millimeters (about 1.77-by-0.79 inches). Discovered in Japan's Tamba City, this ...
While dinosaurs such as Supersaurus were probably longer, fossil remains of these animals are only fragmentary and D. hallorum still remains among the longest known dinosaurs.
