Given:
half life of 
= 6000 years
%quantity contained in sample, 
= 6.25% 
original quantity = 0.0625
Formula used:
Formula for carbon dating is given by:
where,
= amount of radio active material
= amount of original material
= half life
Solution:
Using the formula mentioned above with suitable values given:
t = 24005.097 years
Therefore, the estimated age of the sample of the mummified skin is 24005.097 years
The reason behind the assemblages of fossils is so different because there was a rapid continental drift.
<h3>What is
continental drift?</h3>
When there was a motion that took place among the tectonic plates and as a result there was the movement of the continents. It was a hypothesis in the context of the Earth's continents.
According to it, it is the Earth's continents that have been moved over geologic time relative to each other. Because of all this, there was an appearance of the drift across the ocean bed. All this resulted in assemblages of fossils in such a way, that it appears different on different continents.
Thus, the assemblages of fossils were seen so differently because there was a rapid continental drift.
