Brachiosaurus is estimated to have been between 18 and 22 meters (59 and 72 ft) long; body mass estimates of the subadult holotype specimen range from 28.3 to 46.9 metric tons (31.2 to 51.7 short tons). It had a disproportionately long neck, small skull, and large overall size, all of which are typical for sauropods.
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 ...
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.
One of the most extreme cases of island dwarfism is found in Europasaurus, a relative of the much larger Camarasaurus and Brachiosaurus: it was only about 6.2 m (20 ft) long, an identifying trait of the species. As for all dwarf species, their reduced growth rate led to their small size.
After researching 1948's "International Motion Picture Almanac," film historian Terry Ramsaye cited the inspiration as Herrick's mother's cousin, a Texas wheat farmer named Oscar Pierce.
