Illustration. First described in 1973, [3] Shantungosaurus is known from over five incomplete skeletons. Chinese scientist Xing Xu and his colleagues indicate that Shantungosaurus is very similar to and shares many unique characters with Edmontosaurus, forming a node of an Edmontosaurus–Shantungosaurus clade between North America and Asia, based on the new materials recovered in Shandong.
Two specimens still under study in the collection of the Museum of the Rockies - a 7.5 m (25 ft) tail labelled as MOR 1142 and another labelled as MOR 1609 - indicate that Edmontosaurus annectens could have grown to much larger sizes and reach nearly 15 metres (49 ft) in length, [49] [50] similar to the closesly related Shantungosaurus which ...
Restoration. Barsboldia was a large hadrosaur, previously estimated at 10 metres (33 ft) in length and 5 metric tons (5.5 short tons) in body mass. [2] In 2011, the tibial length was measured at 1.4 m (4.6 ft), rivaling that of Shantungosaurus at 1.47 m (4.8 ft) and that of Magnapaulia at 1.36 m (4.5 ft); this indicates that Barsboldia could have possibly reached within the range of 12–14 ...
The largest known land-dwelling artiodactyl was Hippopotamus gorgops with a length of 4.3 m (14 ft), a height of 2.1 m (6 ft 11 in), and a weight of 5 t (11,000 lb), [63] with its closely related European descendant, Hippopotamus antiquus, rivaling it, estimated to be 14.1 ft (4.3 m) in length and 7,700–9,300 lb (3,500–4,200 kg) in weight.
In 1977 James Hopson introduced the use of estimated encephalization quotients to the topic of dinosaur intelligence, finding Edmontosaurus to have an EQ of 1.5, above that of other ornithischians including earlier relatives like Camptosaurus and Iguanodon and similar to that of carnosaurian theropods and modern crocodilians but below that of ...
The authors estimated the size of Hatzegopteryx by comparing the humerus fragment, 236 mm (9.3 in) long, with that of Quetzalcoatlus, of which one specimen has a 544 mm (1 ft 9.4 in) long humerus. Observing that the Hatzegopteryx fragment presented less than half of the original bone, they established that it could possibly have been "slightly ...
February 10, 2025 at 1:30 AM. Meat enthusiasts have long endorsed the "carnivore diet," a meal plan that includes consuming only animal products such as meat, dairy and eggs — but the program is ...
Saurolophinae is a subfamily of hadrosaurid dinosaurs.It has since the mid-20th century generally been called the Hadrosaurinae, a group of largely non-crested hadrosaurs related to the crested sub-family Lambeosaurinae.
