Robin's Great Coloring Pages: Tyrannosaurus rex and Triceratops Coloring Pages

These are my two newest dinosaur drawings. They were done while I waited for my surgery at the hospital two days ago. I had to have my stent in my trachea replaced.

The first drawing is of a T. rex mother about to flee from an erupting volcano. T. rex lived at the end of the Cretaceous Period and there was an upsurge of volcanic activity those last five million years of the Cretaceous Period.

The latest studies on T. rex say that it may have been as heavy as 19,500 lbs. That is about 9.5 tons. One specimen, nicknamed Scotty, was a Tyrannosaurus rex that was that big. It had injuries consistent with fighting with other T. rex.

It also had bone growth rings that indicated that it was 28 years old when it died. That makes it the oldest. . . and the biggest T. rex ever found.

This T. rex drawing is of a mother with two chicks in her mouth. Evidence suggests that Theropod dinosaurs were hatched in more or less a helpless form. So adult dinosaurs of their species had to care for them. This led to the idea that T. rex was probably a gentle and caring parent.

Like crocodilians, perhaps T. rex parents carried their chicks in their mouth. My surgeon, at the University of Utah Hospital, saw this drawing and my Triceratops drawing and he made copies for his grandchildren to color.

Triceratops was no helpless victim to T. rex, although the Triceratops WERE preyed upon by T. rex. There are fossilized feces called coprolites that came from a T. rex and they have pieces of Triceratops bone in them. I myself have some Tyrannosaur coprolite with pieces of bone embedded in it.

But Triceratops had huge horns as long as broom handles. Triceratops had a shield or frill protecting his or her neck. This made a front-facing Triceratops a formidable opponent. In fact, Triceratops even had a ball joint connection of skull to body. So Triceratops could whip its head around and wield those big brow horns like a double sword.

Triceratops was a Ceratopsian dinosaur and there is considerable evidence that Ceratopsians lived and traveled in herds. So, since there is ALSO evidence that T. rex lived and hunted in packs, it is quite possible that T. rexes, if they wanted to feat on Triceratops meat, had to isolate one animal from the herd. Modern wolves to this with bison or buffalo.

So, here are the two dino drawings, that I did in ink while waiting for my surgery. By the way, the surgery went great so I will be drawing and posting more coloring pages for a while yet. (God willing.)

This Triceratops calf can be altered to be a female by just drawing in a few eyelashes. This is a cartooning trick. You just add eyelashes to make the animal a female.
