"The Archbishop" is a giant brachiosaurid sauropod dinosaur similar to Brachiosaurus and Giraffatitan. It was long considered a specimen of Brachiosaurus (now Giraffatitan) brancai due to being found in the same formation in Tendaguru, Tanzania.
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 ...
Traditionally, the distinctive high-crested skull was seen as a characteristic of the genus Brachiosaurus, to which Giraffatitan brancai was originally referred; however, it is possible that Brachiosaurus altithorax did not show this feature, since within the traditional Brachiosaurus material it is known only from Tanzanian specimens now ...
The crests and frills of some dinosaurs, like the marginocephalians, theropods and lambeosaurines, may have been too fragile to be used for active defense, and so they were likely used for sexual or aggressive displays, though little is known about dinosaur mating and territorialism. Head wounds from bites suggest that theropods, at least ...
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 ...
It simply may have been too risky, they said, for a predator - even one weighing multiple tons - to try to bring down an adult sauropod perhaps five to 10 times more massive like Brachiosaurus.
Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
Sauropods, the giant long-necked long-tailed four-legged herbivorous dinosaurs, are among the most common and famous Morrison fossils. A few have uncertain relationships, like "Apatosaurus" minimus (possibly a basal titanosauriform) and Haplocanthosaurus.
