What were the dominant animals in the preCambrian era?
The dominant organisms during the Precambrian include the proarticulatans, such as Dickinsonia, Yorgia, and Praecambridium which were a group of "air-mattress" organisms possibly related to modern day placozoans, rangeomorphs, such as Rangea, and Charnia, which were frond-shaped organisms that had bilateral to radial symmetries, and the trilobozoans, like Tribrachidium, which were disk-like organisms with a tri-radial symmetry, possibly related to cnidarians.The ancestral mollusk, Kimberellia, is found throughout Precambrian strata of the world.There were also sponges, and what have been interpreted as the polyps and medusae of cnidarians during the Precambrian, as well. Very primitive worms and arthropods appear at the very end of the Precambrian, as it transitions into the Cambrian period.
