the History of Dinosaurs

I apologize if the titles of these posts make it sound like you will actually be learning something from reading my blog. I am more of a "looker" than a reader. I don't really remember reading any of the plaques in this part of the National History Museum last week, but here are some "Wacky and Interesting Facts" that I just Googled for you ~
** The heaviest dinosaur was the Brachiosaurus at 80 tons. It was the equivalent to 17 African Elephants. The Brachiosaurus was 16m tall and 26m long and is the largest dinosaur skeleton to be mounted in a museum. ** The smallest fully-grown fossil dinosaur is the little bird-hipped plant-eater like Lesothosaurus, which was only the size of a chicken. Smaller fossilized examples have been found but these are of baby dinosaurs.
*A Stegosaurus had a brain the size of a walnut - only 3 centimeters long and weighing 75 grams. ** The dinosaur with the longest name was Micropachycephalosaurus meaning "tiny thick-headed lizard". Its fossils have been found in China, and it was named in 1978 by the Chinese palaeontologist Dong.  ** The oldest dinosaurs known are 230 million years old, and have been found in Madagascar. As yet they have not been formally named. Before this Eoraptor, meaning "dawn thief" had held the title at 228 million years.
The only fact I can remember reading in the museum (since I didn't take any pictures of the information panels) is that one kind of dinosaur is 6 pounds when it is born, but as an adult weighs 12,000 pounds. Or maybe it was 120,000 pounds!? I should read more. Knowledge is power!
