Why are fossils so rare?
Fossils are rare because their formation and discovery depend on chains of ecological and geological events that occur over deep time. … As such, finding fossils involves not only perseverance and luck, but the discovery of any particular fossil also depends on the chance that the specimen preserved in the first place.
How are fossils classified?
Trace fossils are classified in various ways for different purposes. Traces can be classified taxonomically (by morphology), ethologically (by behavior), and toponomically, that is, according to their relationship to the surrounding sedimentary layers.
