In an article on geology.com, there is news of early life forms being preserved in rock in a remote area in Africa. In the Tables Mountains of South Africa fossilized life forms that are billions of years old have been found preserves with guts, eyes and muscles. The reason for such well preserved fossils are the layers of algae it has been preserved in and a past ice cap that covered the rock it is in. Over the past few hundred years a dry wind has slowly revealed these underlying fossils. Perhaps if geologists kind identify other rock layers with these similar features we may be able to find fossils of this same condition. To go about doing this, we may just look at rock that we know have previously been covered by ice as well. One thing is for sure, when all the glaciers in the world are gone we can look forward to extremely well preserved fossils.
