Brachiosaurus is a well-known sauropod dinosaur. Its name comes from its long upper arm bone, which is taller than most people. For almost 100 years, it was considered the tallest dinosaur at over 20 meters, but taller ones have since been discovered.

Brachiosaurus was discovered in 1900 in Colorado and named by Elmer Riggs in 1903. It was originally thought to have lived during the Jurassic period in the United States, Africa, and Europe. Scientists believed Africa and North America were connected then, but the African Brachiosaurus is now considered a different genus called Giraffatitan.

New studies suggest Brachiosaurus held its neck at a 45 to 60 degree angle, not as high as once thought.

I have a male, two females and two juveniles in my collection. By the way sexual dimorphism or differences is almost impossible to tell from fossil remains, although the debate does continue.

Again our intrepid big game hunter is shown for size comparison. He is even dwarfed by the “baby” on the right. Imagine mounting that on your wall!
