Fossils are fascinating because they are clues to the past.
By analyzing animal or plant fossils, we can extract data and learn much more about their biology and behavior. There are several ways in which paleontologists study fossils to determine their age and other factors. Plant and animals are turned into fossils in a variety of ways.
The rocks themselves were never alive, but their existence shows the very simple single-cell organisms that made them were present on Earth hundreds of millions of years earlier than previously thought. Vickie Bennett from the Australian National University, who also worked on the study, said the research provided a new perspective on Earth's history and "turns the study of planetary habitability on its head"."Rather than speculating about potential early environments, for the first time we have rocks that we know record the conditions and environments that sustained early life," she said.
The discovery could help the hunt for life on Mars, considered the most likely location for microbial life-forms among other planets in the Solar System.
So let’s say I am hiking in the wilderness and fall over dead near some rocks and I’m lucky enough to be buried by a landslide so that my remains become fossilized. However, I’m sure this future archaeologist would use more than one technique to date my fossil remains.
These layers build up over time to create solid rocks.So we need to be careful about dating and dates because dates can be easily deceiving.Below is a link that shows some of the various dating techniques used to date fossil remains of early humans et al.so you can still see some of the original features," he said. Although many people think that fossils are only bones, they can also be several other things, including prints, pieces of plants, nests, eggs, and animal droppings.
