Precambrian is a geologic period that extends as back as 4.500 million years ago. Fossils are very rare from that period of time.

What fossil records do you have from the Precambrian life?
very little, there are stromatolites, domed mates of microscopic algae that are aged as precambrian. No other fossils in the precambrian
For which segment of the Earth's geologic history are fossils rarely found?
precambrian
What geological period has fossils of the most primitive life forms?
20,000 b.c.
The lack of Precambrian index fossils is the primary reason that?
correlation between rock units is impossible
Why are there few fossils from the precambrian era?
Actually, it isn't really true! We now know (unlike Darwin who would have rejoiced to know what we now know!) that fossils in the PreCambrian are numerous and spread world-wide. But many are very small and not easily recognised or exist in specialised geologically circumstance, often preserved in relatively little-known places. Much PreCambrian rock is igneous, products of vulcanism, and obviously do not preserve fossils. But where suitable conditions prevailed, unusual fossils can be found are a the subject of a great deal of study. Many of the best preserved are where fine volcanic ash settled over the ancient seabed preserving the soft-bodied forms which were around 500-600ma ago. Precambrian fossils may be found at several localities in UK (notably Charnwood Forest in Leicestershire), in Canada, Namibia, Russia, China and especially in Australia.
What fossils are from the Precambrian era?
Stromatolites
Any precambrian tine animals and plants that have turned into fossils?
Yes, although the fossil record for the precambrian period is scarce. See related link.
What are the most common precambrian fossils are?
stromatolites
What are the most common precambrian fossils called?
stromatolites

One reason fossils are rarely found in Precambrian rocks is that?
Precambrian rocks contain relatively fewer fossils than rocks from different eras. This may be due to the fact that the rocks from this era were subject to a lot of heat and pressure, or were exposed to erosion.
For which segment of the Earth's geologic history are fossils rarely found?
precambrian
Fossils of organisms found in the early precambrian are all of?
unicellular prokaryoytes
What are most common Precambrian fossils of layered mounds of calcium carbonate called?
stromatolites
What prevents us from finding precambrian fossils?
Most rocks from that era are deeply buried.
What geological period has fossils of the most primitive life forms?
20,000 b.c.
What have scientist inferred from fossil stromatolites?
Stromatolites were much more abundant on the planet in Precambrian times which means that fossils found around stromatolites are typically from the Precambrian era.
