Question: Which fossils do you think would be the oldest which would be the youngest Why?

The oldest layers are on the bottom, and the youngest layers are on the top. Because sediments sometimes include once-living organisms, sedimentary rock often contains a lot of fossils. Fossils are once-living organisms that have been turned into rock, in which the shape or form of the organism can still be seen.

What are the oldest to youngest fossils?

The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently). A fossil is the remains or traces of plants and animals that lived long ago.

Which fossil sequence is an order from oldest to youngest?

The law of superposition simply states that for non- deformed geologic strata, “sedimentary layers are deposited in a time sequence, with the oldest on the bottom and the youngest on the top”.

Which fossils will be the oldest?

The oldest known fossils, in fact, are cyanobacteria from Archaean rocks of western Australia, dated 3.5 billion years old. This may be somewhat surprising, since the oldest rocks are only a little older: 3.8 billion years old! Cyanobacteria are among the easiest microfossils to recognize.

Do fossils hold their value?

Although the highly publicized sale of unique fossils such as the Tyrannosaurus rex “Sue” or Tarbosaurus bataar (which has subsequently been seized by Federal authorities for repatriation to Mongolia) leads the public to believe all fossils are increasing in value, our findings suggest that the fossils most in demand
