But how can old bones tell scientists anything? More in-depth information about old civilizations is also available due to radiocarbon dating results on bones. Write down at least three new facts you learn about radioactive decay. The protein, which is mostly collagen, provides strength and flexibility to the bone whereas the hydroxyapatite gives the bone its rigidity and solid structure.

However, the open lattice structure of the hydroxyapatite makes it highly contaminated with carbonates from ground water. How did you guys start off like did you start off with very few people or a lot and i love these types of things i want to be a archealogist when i grow up! This is the excerpt for a placeholder post.

Archaeologists unearthed the bones of at least five people at Jebel Irhoud, a former barite mine km west of Marrakesh, in excavations that lasted years.

No cancellation charges are applied if a charred bone is deemed unsuitable for dating after pretreatment. Archaeologists have long used carbon dating also known as radiocarbon dating to estimate the age of certain objects. In recent years, forensic scientists have started to apply carbon dating to cases in which law enforcement agencies hope to find out the age of a skeleton or other unidentified human remains. The remains, which resemble modern humans more than any other species, were recovered from the base of an old limestone cave that had its roof smashed in during mining operations at the site.
