Wrong! Science is precise when current data is available.
Here you are talking about hundreds of millions ago, so scientists must try to put 2 and 2 together by extrapolation of old data such as bones of ancient creatures.

There is no such thing as 'precise science' when it comes to investigating data and things from many millions of years ago. A lot of it is extrapolation and guesswork and theories, such as the theory of evolution, which is still unproven and may never be.
