In what era had small simple marine organisms?
Precambrian Era
Early organisms in the Precambrian era converted to oxygen.?
Carbon dioxide
Why are more fossils found in the paleozoic era than in the precambrian era?
During the Precambrian times, life was mostly limited to single celled organisms. Life that was not single cellular didn't have any hard body part (like teeth, bones, shells, etc.) and so they weren't preserved.
What are the four geologic time scale eras from oldest to most recent?
The 4 eras are Cenozoic era, the mesozoic era, the paleozoic era, and the precambrian era.
What era featured the longest periods with no life forms on Earth.?
Precambrian
In what era had small simple marine organisms?
Precambrian Era
Which example best describes life in the precambrian era?
During the late Precambrian, about 560 million years ago, the first confirmed macroscopic multicellular organisms appeared. Around 558 million years ago, the first mollusk, Kimberella,appeared in the fossil record.
Early organisms in the Precambrian era converted to oxygen.?
Carbon dioxide
Early organisms in the Precambrian era converted what to oxygen?
Carbon Dioxcide
Which describes the correct order of the geologic time scale from oldest to most recent?
ok im going to start off by saying this, the last answerer is stupid, and doesnt know what he is talking about. it goes from: PERIOD ERA EPOCH there you go ;)
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.
Did the precambrian era occur first?
Yes. The first era was the precambrian era followed by the paleozoic era then the mesozoic era than the Cenozoic era.
Historians know least about era do?
**Precambrian**
When was the Founding Era?
the Precambrian era
What is the oldest era geologically?
The oldest geological era is the Precambrian period. It is the period of Earth's formation, as well as the origin of the first single and multi-celled organisms.
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 did jellyfish eat during the precambrian time period?
Jellyfish were not even alive during the Precambrian era because only single-celled organisms lived.
