Brachiosaurus Questions and Answers

Q: What is the tallest dinosaur?
from Jerome I, Melbourne, Victoria, Australia; June 19, 2001

A: The brachiosaurids (like Ultrasauros, Sauroposeidon, and Brachiosaurus) are the tallest known dinosaurs.



Q: How does the blood get to the Brachiosaurus' head?
from Taylor W, R., Manitoba, Canada; June 14, 2001

A: BrachiosaurusBrachiosaurus and some of the other large sauropods (the huge long-necked plant-eaters) needed to have large, powerful hearts and very high blood pressure in order to pump blood up the long neck to the head and brain. The head (and brain) of Brachiosaurus was held high (many meters) above its heart. This presents a problem in blood-flow engineering. In order to pump enough oxygenated blood to the head to operate Brachiosaurus' brain (even its tiny sauropod brain) would require a large, powerful heart, tremendously high blood pressure, and wide, muscular blood vessels with many valves (to prevent the back-flow of blood). Brachiosaurus' blood pressure was probably over 400 mm Mercury, three or four times as high as ours.



Q: Were the brachiosaurus front legs or back legs longer?
from ?, ?, ?, ?; May 12, 2001

A: Unlike most dinosaurs, the front legs of Brachiosaurus were longer than the back legs.

Q: Do the tallest dinosaurs always wiegh the most? Why or why not?
from Dave D, Poway, California, United States; April 24, 2001

A: No, the tallest animals are not necessarily the heaviest. For a modern-day example, compare the giraffe and the elephant. The giraffe is much taller, but the elephant weighs much more. Looking at dinosaurs, the giraffe-like Brachiosaurus, Sauroposeidon and Ultrasauros were the tallest dinosaurs, but other sauropods (like Argentinosaurus) weighed more.



Q: What was the diet of herbivore dinosaures during the jurrasic period?
from Siena W., Bolinas, California, United States(unfortunately); April 12, 2001

A: There were many different types of plant-eating dinosaurs during the Jurassic and they ate different plants. For example, Brachiosaurus probably ate leaves from high in the trees, but Stegosaurus probably ate low-lying plants.



Q: when did brachiosaurus live (era and year)
from Rosceda R., ?, ?, ?; April 5, 2001

from Kolby M, Fort Smith, Arkansas, USA; March 12, 2001

A: Brachiosaurus averaged about 40-50 feet (12-16 m) tall.



Q: How long was Brachiosaurus' neck?
from Emily and Sarah, Coralville, IA, USA; February 19, 2001

Q: What happened to the ultrasauros
from tf, Calyton, NM, United states; January 14, 2001

A: Ultrasauros is a dubious genus; it is thought that its fossils are probably bits of a huge Brachiosaurus (the enormous shoulder bone) and a Supersaurus (the vertebrae).



Q: When did Brachiosaurus became extinct.
from Linnea.G., Cumberland, Wisconsin, U.S.A.; January 10, 2001

Q: What does a Brachiosaurus's digestive system look like?
from Mary F., Anchorage, Alaska, USa; January 2, 2001
