Paleontology radiometric dating

Trace fossils may not include an actual fossilized dinosaur, but in some cases they offer information that complete fossils cannot.

Trace fossils have offered Paleontologist information regarding the external appearance of dinosaurs, including the texture of their skin, and in some cases the presence of feathers.

Coprolites- One way of finding out information about any creatures, especially dinosaurs, is to find out what they ate and Coprolites provide us with evidence of that.

Coprolites are fossilized dung, and can be analyzed to find out what kind of food the creature that left it consumed.

Geochemical Evidence- Geochemical evidence reveals many of the secrets that the naked eye cannot, and by using this technique both Paleontologist and Archeologist as well search for prehistoric life whose traces have been trapped inside of rock.

Scientists use geochemical evidence to search for previous life forms such as Eukaryotic cells, which are the building blocks of multi-cellular organisms.

It is assumed that the accretion of the Earth began soon after the formation of the Ca-Al-rich inclusions and the meteorites.

Since the accretion time of the Earth is not exactly known yet, and the predictions from different accretion models vary between several millions up to about 100 million years, the exact age of the Earth is difficult to define.

Created by a group of scientists who together studied the fossil record and began to notice some interesting characteristics of the fossils they studied, Paleontology evolved each time a new discovery was made.Occasionally the stomach contents of dinosaurs have been fossilized themselves, such as other dinosaurs that became a source of food.These unique specimens provide us with information regarding the hierarchy that existed in the dinosaur world and the interactions between the creatures.Scientists gather information about dinosaurs by relying upon a variety of resources at their disposal, the first of which being human intuition and the ability to observe and theorize.Fossils and the timeline established by the fossil record help scientists turn theory into fact by providing credible evidence that can either support or discredit their theories.

This age represents a compromise between the oldest-known terrestrial minerals – small crystals of zircon from the Jack Hills of Western Australia – and astronomers' and planetologists' determinations of the age of the solar system based in part on radiometric age dating of meteorite material and lunar samples.
