What is one of the primary reasons given for why there are very few fossils from the earliest (pre-Ediacaran fauna) animals?
A. The area covered by land, where early
animals lived, was small so there were fewer
opportunities for sedimentary rocks to form
fossils.
B. The area covered with water was much
smaller than present day, so there were fewer
places for fossilization to occur on the ocean
floor.
C. The earliest animals were soft-bodied and
did not have requisite body parts that could
be fossilized through mineralization.
D. The earliest animals were distributed in
high-oxygen environments, and
decomposition occurred too rapidly for
fossilization to occur.
