For decades, Compsognathus was known as the smallest known non-avian dinosaur, [5] although some dinosaurs discovered later, such as Mahakala and Microraptor, were even smaller. [ 25 ] [ 26 ] The German specimen was estimated to be 70–75 cm (28–30 in) [ 5 ] and 89 cm (35 in) [ 3 ] in length by separate authors, while the larger French ...
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 specimen is actually a very large plesiosaur, possibly reaching 15 m (49 ft) in length. The media published exaggerated reports claiming it was 25 metres (82 ft) long, and weighed up to 150,000 kilograms (330,000 lb), which would have made it among the largest predators of all time. [38] [39]
Compsognathus longipes was formerly the smallest known dinosaur. It was around the size of a chicken when fully grown: around 1 m (3 ft 3 in) long and weighing 2.5 kg (5.5 lb). [ 24 ] However, recently discovered adult specimens of other dinosaurs are smaller than Compsognathus , including Caenagnathasia , Microraptor and Parvicursor , all of ...
Pterosaurs included the largest flying animals ever to have lived. They are a clade of prehistoric archosaurian reptiles closely related to dinosaurs. Species among pterosaurs occupied several types of environments, which ranged from aquatic to forested. Below are the lists that comprise the smallest and the largest pterosaurs known as of 2022.
Paleontologists classified a new species of sauropod that now ranks as Australia's largest dinosaur. The species was known as Australotitan cooperensis. Behemoth 98-foot-long dinosaur confirmed to ...
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 ...
