For example, cracks in the sediment running along the fossil, plant roots and animal burrows against the fossil, and even different sized substrates other than the normal sediment lying against the fossil can change the color on parts of the fossil. These complicating factors, and others, can give the fossil a beautiful multicolored appearance; it can give them a cloudy, speckled, and even a streaked appearance.
