Brachiosaurus

Brachiosaurus, whose name signifies "arm reptile," was the giraffe dinosaur of the Jurassic. With its long neck (very nearly 30 feet in length) and tall front legs, this goliath sauropod could nip new shoots from the highest points of trees in excess of 40 feet over the ground.  in case Brachiosaurus were alive today, it could look into fourth story windows. This is the biggest sauropod known from almost complete skeletons. For some scientistss, this is the boss for size. Gauging 50 tons, probably as much as seven elephants, Brachiosaurus was a gigantic dinosaur that needed to take care of continually. The front legs were taller than the back legs, and the tail was generally short.  Brachiosaurus was weighty toward the front and light in the back. the rib confine was gigantic, but since the legs were so tall, the stomach was so distant the  ground that a stegosaurus could stroll under it. The long neck and front legs look like the body of a giraffe, and it is concei

Maiasaura peeblesorum

Space-travelling dinosaur may seem like science fiction, but one dinosaur actually made it into space in 1985. Astronaut Loren Acton packed bone fragments from a historic Montana dig before boarding space lab 2, making Maiasaura the first dinosaur to orbit the earth. That might have given some paleontologists reason to grin, but what probably excites them more is taking a look back 65-80 million years before the Maiasaura's trip to the stars, when this duck billed plant eater lived among the likes of Tyrannosaurs and velociraptor. 



 The duck-billed Maiasaura were big dinosaur and big eaters. These herbivores had fiber-rich diets that consisted of berries, seeds and up to 20 pounds of leaves a day. However, oddly enough, its sharp, enameled teeth lined its cheeks rather than its beak. Weighing in at about 8,000 pounds, the Maiasaura were part of the Hadrosauridae family, growing to be about 30 feet long and 8 feet tall. It could navigate on either two or four legs, but perhaps had a bit of an uneven stance, as it had a stubby arms with four-fingered hands and hooved back legs. Its strong tail was presumed to be used as a balancing device.

 The Maiasaura specimens found to date have all come from the late cretaceous period's two medicine formation in western Montana. Because fossils have been discovered in groups totaling up to 10,000 Maiasaura are alleged to be herders who needed to travel seasonally I search of food, and then returned annually to breed in their home colonies. There is a reason the Maiasaura have been nicknamed the "good mother lizard". Scientists repeatedly found fossils alongside nests that consisted up to 25 grapefr-sized eggs. It is believed that the Maiasaura moms nurtured the hatchlings until they at least doubled in size longer than many other dinosaurs stayed with their young.
