MICROFOSSILS ARE the tiny remains of bacteria, protists, fungi, animals, and plants. These data were produced by Paul Bown, a shipboard scientist during. The oolitic carbonates could be either an in situ near-shore deposit or resedimented basinal beds. These fossils are large enough to study without a microscope. Put the paragraphs of the argumentative essay in the correct order. Although prokaryotes and protists seem simpler, they arose much earlier than their multicellular descendants and so might be considered more primitive, but some have also existed for at least 3.5 billion years and must therefore be considered very successful indeed. e.g., J Biol Chem or Nature.
