Can anyone shed some light on how these fossils, which are often seen in either single specimens or large slabs, ..how they are polished to such a clear diplay, and then on the back side there is normally a similar fine cut, but with a very bad finish.
Also, i find that these fossils are ussually all the same color, this is due to the fossilization conditions such as, materials, region, era, ect... Correct?
Also peculiar that they often do not contain other traces of the organism.
