Tyrannosaurus rex vs Triceratops horridus

This blog post is about T. rex and Triceratops.  These two animals were some of the last non-avian dinosaurs to live on the Earth.  They were big and they were rivals.  Fossilized droppings are called coprolite.  Coprolite has been found that contains pieces of what are obviously Triceratops bones.  Since we know that T. rex had very powerful jaws we can infer that that coprolite was once droppings from a Tyrannosaurus rex.  There were many Triceratops in the late Cretaceous Period.  They were herding animals.  Triceratops was the biggest Ceratopsian dinosaur to ever live.  But Tyrannosaurus rex was one of the largest land predators to ever live, and T. rex had the strongest bite force of any animal that ever lived.

Triceratops horidus had a ball joint where its head attached to its neck.  This meant that it could swing its long brow horns like two long swords.  Triceratops was around 30 feet long and 10 feet tall.  Triceratops had the biggest head of any land animal ever!  Its brow horns were the length of broomsticks...but much sharper and much stronger!  Recent estimates of Triceratops weight put it at up to 26,000 lbs, (12,000 kg).  

Tyrannosaurus rex was 40 feet long and 18 feet tall.  It had a crunching bite that could crush right through bones.  When a T. rex killed an animal, the prey was eaten... bones and all.  Models of T. rex jaws have been built based on the muscle scars found on the jaw and skull.  Those models could crush bone with ease.  T. rex teeth were up to 9 inches (23 cm) long.  Some new computerized estimates of the biggest known T. rex, Sue, put her weight put it at 18,000 lbs, (8,160 kg).  Sue's fossilized skeleton is at the Field Museum of Natural History in Chicago.

So, Tyrannosaurus rex was taller than a full sized Triceratops, but a full sized Triceratops was actually heavier than the biggest known T.rex.  Both had deadly weapons to use in a fight.  Therefore we can see that a fight between T. rex and Triceratops would have been quite a match!

Today's drawings are individual drawings of T. rex and Triceratops.  I will eventually do a coloring page drawing of the above "T. rex vs Triceratops".  For now enjoy coloring today's dinosaurs.  Technically Triceratops is my favorite herbivorous dinosaur and T. rex is my favorite carnivorous dinosaur. The below drawings are done in part with dot shading.  Feel free to color the dotted areas as well as the other parts of the pictures.  I hope you enjoy coloring them.

The dot pattern is to show where the person coloring
 the picture COULD use a darker color.

Triceratops horridus with Bulls eye Pattern
The spots are done in a bulls eye or target pattern.
 This can also be called a false eye pattern that helps make the
 animal look bigger to a predator.
