Herbivorous Dinosaurs

Some grew to magnificent sizes such as the more well known dinosaur, the Brachiosaurus. Brachiosaurus had a giraffe-like stance and measured a great height of 40 - 50 feet (12 - 16 metres). Their length could measure 86 feet (around 26 metres).

This huge Brachiosaurus dinosaur would probably have eaten around 183 kilograms (400 pounds) of food per day to meet its daily energy requirements. Brachiosaurus probably roamed in herds and may have migrated when they depleted their local food supply. Brachiosaurus may have hatched from eggs, like other sauropods.

Huge Dinosaurs

Recent research has suggested that the Sauroposeidon dinosaur (which means Earthquake God Lizard) was a colossal 60 feet tall and weighed around 60 tons and was the largest dinosaur that ever walked the earth. This dinosaur could have peered through a 6 floor building window with ease.

This ground shaking monster had the longest neck in fossil records. Professor Cifelli led the team that examined bones unearthed in south-eastern Oklahoma in 1994. When they were first catalogued, he thought they might be the trunks of prehistoric trees. However, closer examination revealed that they belonged to the Sauroposeidon dinosaur, a larger relative of the better-known Brachiosaurus, which could stretch its head up to 13.5 metres (45 feet). Each of the neck bones of the Sauroposeidon measured around 120 centimetres (4 feet) long. The neck of the Sauroposeidon is about a third longer and a lot more specialised than that of the Brachiosaurus. Find out more about the Sauroposeidon dinosaur here.......

More About Dinosaurs

Dinosaurs are a specific subgroup of the archosaurs, a group that also includes crocodiles, pterosaurs, and birds. although pterosaurs are close relations, they are not true dinosaurs. Dinosaurs were vertebrate animals that dominated terrestrial ecosystems for over 160 million years, first appearing approximately 230 million years ago. At the end of the Cretaceous Period, 65 million years ago, dinosaurs experienced a catastrophic extinction, which ended their dominance on land. Taxonomists consider modern birds to be the direct descendants of theropod dinosaurs. Interpretations of dinosaur behaviour are generally based on the pose of body fossils and their habitat, computer simulations of their biomechanics, and comparisons with modern animals in similar ecological niches. As such, the current understanding of dinosaur behaviour relies on speculation, and will likely remain controversial for the foreseeable future. However, there is general agreement that some behaviours which are common in crocodiles and birds, dinosaurs closest living relatives, were also common among dinosaurs.
