Dinosaur fossils can found rocks dating

Fossils are usually found within rocks of the Earth's crust.

We know that organisms have evolved and changed over the years because of the clues that fossils give us.

The in situ U-Pb technique involves laser ablation to remove minute particles of the fossil which then undergo isotopic analysis.

The results have now been published in Geology, the journal of the Geological Society of America.

Other examples of fossils used for age dating are conodonts, foraminefera, trilobites, brachiopods, some bryozoans, some species of crinoids, fossil pollen, and even dinosaurs just to name a few.
