Final answer:
Fossils are classified into the Linnaean classification scheme using the traditional biology taxonomy system. Scientists consider various characteristics and use flow charts to identify the phylum and class of the fossils.
Step-by-step explanation:
The classification of fossils follows the traditional biology taxonomy system, known as the Linnaean classification scheme. The major ranks in this scheme are domain, kingdom, phylum, class, order, family, genus, and species. When classifying fossils, scientists consider characteristics such as the type of skeleton, body plan, habitat, and feeding behavior. They also use flow charts and observations to help identify the phylum and class of the fossils.
