Which group of plant evolved during the Mesozoic Era is dominant plant?
Precambrian
Which group of plants evolve during the mesozoic era and dominant today?
Precambrian
How are animals from the Precambrian era generally characterized?
The animals in the Precambrian Period were soft bodied animals. This Era was dominated by single celled organisms: algae, bacteria. Also in existence were jellyfish, spiders, crabs, and worms.
What kind of animals developed near the end of first era?
Animals without backbones, called invertebrates, developed near the end of the Precambrian. Imprints of jellyfish and marine worms have been found in late Precambrian rocks. Because invertebrates were soft, they weren't easily preserved as fossils. This is one of the reasons why the Precambrian fossil record is so sparse.
Which best describes organisms of the Precambrian era?
single-celled organisms and soft, boneless animals
What Were the dominant plants in the precambrian?

the Precambrian era
What animal first appeared during the precambrian era?
As far as we know for the majority of the Precambrian super-eon the only life on earth was bacteria.At the very end of the Precambrian multicelled life evolved. Amonst them jellyfish, invertibrates, sponges and pretty much a prehistoric version of most sealife today. There is also very suggestive evidence for simple plant life in the form of green algae in the Precambrian.
Where was precambrian era?
it was on earth the precambrian era is an era that happend several million years ago on the earths surface
What main characteristic distinguishes the fossil record of the Paleozoic Era from that of the Precambrian Era?
In the beginning of the Paleozoic Era, animals began to develop hard parts like shells and bones.
