Like all sauropod dinosaurs, Brachiosaurus was a quadruped with a small skull, a long neck, a large trunk with a high-ellipsoid cross section, a long, muscular tail and slender, columnar limbs. [51] Large air sacs connected to the lung system were present in the neck and trunk, invading the vertebrae and ribs by bone resorption , greatly ...
Brachiosaurus humerus bone. In 1903, Elmer Samuel Riggs described and named Brachiosaurus. In 1904, he created a new sauropod family, the Brachiosauridae. [9] [1] He published a complete description of the phenotype after examining the humerus, femur, coracoid, and sacrum of the Brachiosaurus holotype that had been prepared at the Field ...
Sauropod neck posture is a subject occasionally debated among scientists, with some favoring postures closer to horizontal whilst others a more upright posture. Research has looked at various avenues of evidence and analysis including: attempting to reconstruct the neutral posture of their necks and estimating range of motion by studying the ...
Of about 600 bones checked, bite marks - often deep grooves left in stout bone - were detected on 68 of them, spanning 40 ind Bone bite marks reveal dinosaur predator-prey dynamics Skip to main ...
Originally, these Supersaurus and Brachiosaurus bones were believed to represent a single dinosaur that was estimated to reach about 25 to 30 meters (82 to 98 ft) long, 8 meters (26 ft) high at the shoulder, 15 meters (49 ft) in total height, and weighing maybe 70 t (77 short tons).
The fibula (plural: fibulae) or calf bone is a long bone located lateral to the tibia; together, the two bones form the lower leg. Generally more slender than the tibia, it is especially thin in derived theropods and birds. [1]: 147 [25]: 53 foramen
A crocodile-like creature bit the neck of a flying dinosaur some 76 million years ago – and scientists have proof.. Archaeologists found the fossilized neck bone of the young pterosaur in Canada ...
The tibia and fibula bones are different from the slender bones of Diplodocus but are nearly indistinguishable from those of Camarasaurus. The fibula is longer and slenderer than the tibia. The foot of Apatosaurus has three claws on the innermost digits; the digit formula is 3-4-5-3-2. The first metatarsal is the stoutest, a feature shared ...
