Glossary
CARBONATE: A rock that contains
high levels of calcium carbonate, i.e. limestone.
MARLS: These contain 35-65% calcium carbonate and the rest of
the rock is made of clay.
DOLOMITES: These are usually formed by the dolomitization of limestones.
This occurs when magnesium is added to the sediment or the rock
during its formation.
SHALE: A fine grained sedimentary rock that splits easily.
DISARTICULATED: A skeleton where the bones have become separated
and are no longer together. The opposite is articulated, where
the skeleton is complete. There can be varying degrees of disarticulation,
ranging from one or two bones being lost to all the bones becoming
separated and being found as solitary fossils.
