: Its extreme neck length has led to intense speculation about its cardiovascular system. To pump blood to its head, Barosaurus would have required an exceptionally large heart and high blood pressure, leading to some (largely dismissed) theories that it may have had as many as eight hearts.
: Studies of its vertebrae have identified "pneumatic hiatuses," indicating it possessed complex air sac systems similar to modern birds, which would have helped lighten its massive frame. Public Exhibits and Impact
: Adults typically measured between 24 and 27 meters (79–89 feet) and weighed roughly 12 to 20 metric tons.
Barosaurus is often the "forgotten" giant of the Late Jurassic, living in the shadow of its more famous cousins like Diplodocus and Apatosaurus . However, a review of this "heavy lizard" reveals a creature with proportions that push the limits of vertebrate biology. Anatomical Highlights
: Research has sometimes confused Barosaurus fossils with Supersaurus due to the massive size of individual vertebrae.
