As far as importance goes, paleontology deals with the study of things long past and long dead, but that doesn't mean it isn't relevant to the age that we are living in. There are just a few of the many specialized fields of study within the science of paleontology. The Triassic climate was dry and warm. Some creatures also can be preserved as fossils in tree sap, like insects in amber, or preserved in ice, like ancient mammoths found in the ice of the Arctic!

Once you are in high school, take as many science and math courses as you can, which can help you prepare for a college major in biology or geology. Dinosaurs are some of the organisms that have lived on Earth in the past, so paleontologists do study dinosaurs. From these tiny organisms, larger animals began to evolve and believe it or not, some even suggest that we came from them as well! As long as the ice doesn't melt the fossil may be preserved for thousands of years. The T-Rex is 22 long and has 39 detatchable organs and other body parts. I've read that there are some pretty giant craters from meteors, several of which are suspected to be the one that killed the dinosaurs off -- so have people checked the rocks near those craters for layers of dust or ash from the dinosaur eras?

Dinosaurs lived between 250 and 65 million years ago, from the early Triassic period to the end of the Cretaceous period. So seek out illustrations that provide kids with reconstructions of dinosaurs in ecological context. Plants and animals leave behind more than just their bodies for paleontologists to study. Radiometric dating can reveal the age often tens of millions of years of a rock or fossil or a tiny grain of pollen by measuring how much its radioactive elements have disintegrated.
The oldest fossil ever discovered was that of a cyanobacteria in Archaen rocks excavated in western Australia. For example, in 2007 in Mexico, a miner found a preserved in amber that may be 25 million years old.

Fossils were being discovered long before man truly realised what they were. For another child's book that encourages critical thinking, see Sneed B. You get two figures plus a really big Spinosaurus and it's babies and eggs. Paleontology simply deals with rocks so old that they are fossilized. Paleontology is the study of plants and animals that lived millions of years ago.
