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.
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 ...
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 fossil skull of the new species, dubbed Oculudentavis, meaning "eye tooth bird," is just over half an inch long.
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 ...
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.
The dinosaur lived 150 million years ago in the late Jurassic period, making it millions of years older than the terrifying Tyrannosaurus rex that roamed the Earth some 66 million to 68 million ...
