Which of the following is an example of an imprint fossil?
Which of the following is an example of a Cast Fossil?
Petrified Fossils are...
Minerals that replace bone, shell or other hard part of the organism
Organism dies and becomes buried under sediment
Model in the shape of a living thing or it's remains
Tracks, footprints, trails
Under What Conditions Do Fossils Form?
Organism having soft parts like worms and die slowly
Organism having hard parts (e.g., bones
or a shell) and a rapid burial following death.
Organism having died 2 years ago.
Organism having wings only and are uncover for a long period.
What were the sequence and conditions that allowed this organism to become a fossil?
The fish was taken to the top of the mountain by a big bird that lived in the past.
the fish was formed at the top of the mountain by itself.
That the top of the mountain once had a body
of water on it and as that water source dried up a fish was left in the mud and covered by sediment.
The mountain grew fish and they died their and became fossils
