Each fossil with the layer where it will be present based on are layer A-BIRDS, layer B -dinosaurs , layer C-amphibians, layer D-Corals ,layer E -trilobites.

<h3>What is the oldest fossil layer?</h3>

The Pilbara area of western Australia's Strelley Pool is home to the oldest known fossils. Stromatolites are fossilized mats of microorganisms wedged between sedimentary layers. The fossils have an age of 3.4 billion years.

<h3>How are the layers containing the fossils organized?</h3>

The Law of Superposition, which asserts that in undisturbed rock sequences, the bottom layers are earlier than the top ones, is the foundation for this theory. Because of this, certain fossil discoveries can be dated using the strata—a particular stratum of rock—in which they were discovered.

1. Do some research and try to identify one to three types of microbes cultured on your plates. Using any resources available to
yarga [219]

Answer:

I have identified <em>Escherichia coli </em>and<em> Bacillus sp.</em>

Explanation:

I obtained my sample from soil, in a park near my house. The common bacteria on soil are gram positive and gram negative.

I found rods, and some are gram positive and long. They others are gram negative and very small and short.

The color of the gram positive is a dark blue, almost purple, and they are big and abundant, they are almost in lines, so I think they are a species of <em>Bacillus.</em>

The gram negative bacteria are extremely small and they look hot pink. They are very probably enterobacteria, and the most common enterobacteria is <em>Escherichia coli</em>. They do not have a particular order of arrangement.
