Which fossilized organisms are most likely found in Earth's lowest rock layer?

Question

A. snails
B. reptiles
C. bacteria
D. dinosaurs

Answer 1

The organisms most likely to be found in Earth's lowest rock layer are C. bacteria. In geological terms, the oldest layers of rock, known as the "Basal" or "Lower" layers, often contain early life forms, which primarily include microorganisms like bacteria. Larger, more complex organisms like snails, reptiles, and dinosaurs appear in the fossil record in later layers.
