BRACHIOSAURUS

SO, I'M OUT WALKING IN THE WOODS AND I COME UPON A Brachiosaurus
amazing. right??
of course I had to look up a few facts:

About 50 feet tall, tiny skull, lowest intelligence of the dinosaurs. (how do scientists figure out these facts?)
Brachiosaurus lived in the middle to late Jurassic period, about 156-145 million years ago. Brachiosaurus was first found in the Grand River Valley, in western Colorado, USA, in 1900.
Brachiosaurus used its large tail as a whip to strike predators and its massive size to crush them. Hey, I know a few dogs that do that!
