what are examples of body traces
shells, bones, teeth
what are examples of traces
tracks, trails, burrows, nests, and feces
what do kind of information do fossils provide
information on ages, depositional environments and evolution
what are favorable conditions for fossilization
-durable skeleton
- living where burial in sediment was likely
- avoided decay, scavenging, and metamorphism
what are the basic requirements to become a fossil
-oxygen poor environment
- low energy setting
- rapid burial in fine grained sediment
what is Taphonomy
the study of all factors that affect an organism from time of death to the time of discovery as a fossil
