Fossils
I. Fossils
Remains
or traces of living things
from long ago.
Bones or footprints preserved in
stone
Provide direct evidence of
organisms that lived long ago and
changes in the environment.
Organism dies and is
buried in sediment
Sediment turns into
rock over time. Fossil
created!!
II. Original Remains
Actual
bodies or parts of
organisms are called original
remains.
Can be trapped in ice, amber
(tree sap), or Tar (thick oily
liquid).
III. Fossils in Rocks
Mold-
visible shape left over by an
animal.
Cast- a solid model in the shape of
the organism
Petrified- cells are replaced by
minerals
Carbon Film- visible layer of carbon
producing image
Trace- footprints, trails, holes, feces
IV. Fossils show change
Ice
Cores- Tubular sample shows
layers of snow and ice over many
years.
Scientists can analyze air trapped
in ice, dust, ash, and fossils.
Aid in understanding climate and
how weather patterns have
changed.
