CAMBRIAN
Period
The Cambrian period was characterized
by an interesting diversity of life in the seas. Life had not yet
evolved upon land. The highest forms of life existing at this time
were the trilobites, which reached lengths up to two feet. But
most trilobites were about an inch long, some were so small that
their fossil remains can be seen only with a microscope. Here is
shown a view of the ocean floor during this period with a
gathering of denizens from its shadowy depths. Species include Paradoxides
gracilis (trilobite), Hydrocephalus minor
(trilobite), Peronopsis integra (trilobite) Stromatocystis
pentangularis, & Acadocrinus nuntius.
