Contoh fossil

• Chitinozoans and a few graptolites were found in the unit, but no other fossils.

• However, their exact stratigraphic relation to the trace fossils is not clear.

• In this chapter typical examples of the kinds of fossils most commonly encountered are illustrated by beautiful specimens.

• At the opposite end of the scale from the phylum is the smallest unit of classification usually used for fossils: the species.

• The small, lentil-shaped fossils are a separate form of the same species.

• Most bivalve fossils are a few centimetres long; the ideal size for collecting.

• Here, no vertebrates at all could be found, the fossils consisting only of invertebrates such as the trilobites.

• However, this technique only provides an external morphological description of putative fossilized cells and is incapable of distinguishing between abiotic fossils of similar morphologies.
