Brachiosaurus

 

• Late Jurassic
• North America and Africa
• 75 feet long (May have been up to 130 feet)
• Was a member of the 'Long-necked' dinosaurs. Many of the bones had openings in them to make the skeleton lighter in weight. These animals were plant eaters. Large adults weighted 90 tons (180,000 pounds), about 12 times the weight of a large male elephant.
