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.
What can scientist inferred by looking at fossil footprints?
what type of dinosaur it is and its weight
What is an ancient fossil that are found in dome-shaped rocks composed of thin layers of sediment pressed tightly together called?
Stromatolites
Are stromatolites fossils of early organisms?
That's right; stromatolites are fossils of very old bacterial colonies. Stromatolites are layered accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains by bio-films of microorganisms, especially cyanobacteria (commonly known as blue-green algae). Stromatolites are a major constituent of the fossil record for about the first 3.5 billion years of life on earth and were responsible for creating the atmosphere we breathe.
What two major developments helped scientists explain the fossil record?
The principle of fossil succession and the theory of evolution have helped scientists explain the fossil record.

What is the most common precambrian fossil are layered mounds of calcium carbonate called?
stromatolites
Name of the oldest fossil found in Australia?
The oldest fossils in Australia are 3.5 billion year old stromatolites. Stromatolites are layered accretions of prokaryotic microbes, most often made up of photosynthetic organisms. Stromatolites still live in Australia today.

Stromatolites
How scientists estimate the age in years of a fossil?
Scientists can use carbon dating to determine the age of a fossil.
What process do scientists think provided earth with an oxygen-rich atmosphere?
Scientists believe that stromatolites were responsible for providing an oxygen-rich atmosphere in precambrian times. Stromatolites are structures formed of sediment. The cyanobacteria that formed these structures were photoautotrophs that used sunlight, carbon dioxide and water to produce their food and a byproduct of oxygen.

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

The principle of fossil succession and the theory of evolution have helped scientists explain the fossil record.
What are the oldest fossil and what have they told us about the first organisms?
Some of the oldest known fossils are stromatolites, dating to 3.5 billion years ago. Stromatolites still exist today. They are round colonies of photosynthetic, single felled organisms without nuclei (prokaryotes).
Which scientists inferred that an atom positive charge must be clustered in the nucleus?
