Matthew Bonnan [42] [43] has shown that sauropod dinosaur long bones grew isometrically: that is, there was little to no change in shape as juvenile sauropods became gigantic adults. Bonnan suggested that this odd scaling pattern (most vertebrates show significant shape changes in long bones associated with increasing weight support) might be ...
At 40 centimetres (16 in) long, the skull of Lishulong is larger than any other sauropodomorph from the Lufeng Formation. The cervical vertebrae are very large and elongated; the centrum of the first preserved cervical vertebra (the axis) is 16.3 centimetres (6.4 in) long, and the centrum of the last preserved cervical vertebra (the tenth consecutive bone in the series) is 19.9 centimetres (7. ...
The neck posture and feeding strategies of sauropod dinosaurs is a controversial topic. Andreas Christian and colleagues analysed the neck of M. youngi and found that when articulated in a neutral posture, the neck was almost straight, with a slight upward bend at the base and a slight downward bend towards the head. The base of the neck has ...
Diplodocus is among the most easily identifiable dinosaurs, with its typical sauropod shape, long neck and tail, and four sturdy legs. For many years, it was the longest dinosaur known. For many years, it was the longest dinosaur known.
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 ...
The neck, of which all 18 vertebrae are present, is nearly 15 meters long and is the longest complete neck ever discovered of any animal. [2] The vertebral column is overall among the most complete of any sauropod specimen from Asia. [1] The cervical [1] and dorsal vertebrae [3] have been described in detail.
Diplodocoidea is a superfamily of sauropod dinosaurs, which included some of the longest animals of all time, including slender giants like Supersaurus, Diplodocus, Apatosaurus, and Amphicoelias. Most had very long necks and long, whip-like tails; however, one family (the dicraeosaurids ) are the only known sauropods to have re-evolved a short ...
The genus is a member of the Diplodocinae, a subfamily of large long-necked dinosaurs with whiplike tails. Ardetosaurus represents one of many distinct sauropod taxa that coexisted in this formation. The Ardetosaurus holotype was collected in 1993 before being shipped to Switzerland, from which it was later sent to Germany, where it was damaged ...
