The body of the Triceratops was big and round, planted on top of short sturdy legs. It was 8 meters long, about 3 meters tall and weighed somewhere between 6 and 8 tons (the size of an elephant). Triceratops means "Three Horned Face" in Greek. It is called that because it has three horns - two above its eyes and one on its nose. It had a big frill that extended up above the head.
A T-rex, or Tyrannosaurus rex, was a dinosaur with skin of a crocodile-like texture. They were approximately forty feet tall, but their jaws and mouths were massive in proportion to their body. They stood on two legs and had two small arms.
T Rex was a large theropod dinosaur, which meant it had birdlike hip bones, and was a large carnivore. It stood nearly twenty feet tall, and was forty or more feet long, and weighed 4-6 tons. It was the largest of the Cretaceous Period tyrannosaurs, which included Albertosaurus, Tarbosaurus, Nannotyrannus, and many others. It walked on two large hind legs, and had very small, nearly useless forelegs.
Trilobites resembled horseshoe crabs.They were marine invertebrates that had hard shells. The body was divided into three parts ("tri"), the cephalon (head), the segmented thorax, and the pygidium (tail piece). These arthropods had jointed legs, compound eyes, and antennae. They ranged in size from less than 1/4 inch to over 2 feet long.
It looks like a hippopotamus with three horns, one each in front of the ears and another one on the snout, a little higher from the nose. It has a skin-like frill like that of an iguana's. I saw pics of a triceratop varying in color, green, gray, brown and black. Hope that helps. :)

Troodon was 7.9 feet long, which was relatively small for a dinosaur. It weighed 110 pounds. Troodon had long, slender hind limbs, which suggest that it ran quickly. It had large, retractable claws on its second toes, which for practicality, were raised off the ground when running. It had large eyes for night vision and a light, forward-facing skull for depth perception.

It looked a lot like a shark with an elongated snout and an extra pair of anal fins.

Trilobites are arthropods (like spiders)
Because they are powerful evidence for the Theory of Evolution. There are thousands to millions of species of trilobites. Some look like pillbugs to ones that walking pincushions. The range of trilobites grow tremendously with the fossil record. As the Cambrian Period advances the diversity of trilobites grows to massive levels. Plus they are among the oldest fossils found, about 500 million years old. They ebb and flow with current accepted extinction events too, rather than with the proposed theories presented by Creationists. It is more interesting to look at trilobites from why they support evolution. Science is about gaining support for a theory, not disproving.
The Trilobites was created in 1984.
Shale is the usual rock type to look for.
Trilobites did not have jaws, therefore they could not bite.
Trilobites are extinct but they were marine animals.
Scientists believe that trilobites reproduced sexually. These prehistoric and extinct creatures were a type of arthropod that probably laid eggs. Trilobites lived about 250 million years ago.
Where DID trilobites live? In the ocean, between 530 million and 250 million years ago.
Trilobites became extinct about 250 million years ago, in the Mesozoic Era.
The first trilobites lived in the Cambrian then lived all the way through the permian
