My kids love dinosaurs and other prehistoric creatures. However, people who exploit this genre don't seem to keep up with the research. Here are some points that everyone should make note of, especially toy and film makers:
Tyrannosaurus Rex has TWO FINGERS. Other theropods may have three or more but T-Rex has TWO. He also has a horizontal body, not the verticle, upright posture of some dude in a rubber Godzilla suit.
Brontosaurus has been removed from the world of dinosaurs. What paleantologists thought was Brontosaurus was the body of one dinosaur with the skull of another. The corrected version is now called APOTOSAURUS. From now on, if you are thinking brontosaurus, say apotosaurus instead.
Dimetrodon was not a dinosaur. He was a precursor to dinosaurs and is just considered a prehistoric reptile with legs out to the sides of his body (Dinosaurs have straight up and down legs).
There are NO Sabre Tooth TIGERS. The are known as Sabre Tooth CATS. Stop saying "tiger."
The consistency has to start somewhere. Please feel free to correct me if I'm wrong on any points.
