At first, there were not many methods of dating were available, but now with advancement in the technology, we mainly have two types of techniques to ascertain ages of ancient belongings.

Potassium-40 on the other hand has a half like of 1.25 billion years and is common in rocks and minerals.

This makes it ideal for dating much older rocks and fossils.

In relative dating the exact age of the object is not known; the only thing which made clear using this is that which of the two artifacts is older.This uses radioactive minerals that occur in rocks and fossils almost like a geological clock.It’s often much easier to date volcanic rocks than the fossils themselves or the sedimentary rocks they are found in.The Wheeler Formation has been previously dated to approximately 507 million year old, so we know the trilobite is also about 507 million years old.But, how can we determine how old a rock formation is, if it hasn’t previously been dated?
