What kind of organisms do the earliest fossils represent?
The earliest fossils represent plants.
When did land based animals first become common?
Land based animals first became common in the Paleozoic Era. It is the earliest era of the 3 in the Phanerozoic Eon.
Where might you find fossils?
you might find them i desert
Can you find dinosaurs fossils in Tennessee?
yes
What are the most common types of fossils found in Florida?
The most common four types of fossils are:mold fossils(a fossilized impression made in the substrate - a negative image of the organism)cast fossils(formed when a mold is filled in)trace fossils = ichnofossils(fossilized nests, gastroliths, burrows, footprints, etc.)true form fossils(fossils of the actual animal or animal part).
What kind of organisms do the earliest fossils represent?
The earliest fossils represent plants.
What domain do fossils of 3.5 billion years ago belong in?
They are fossils cyanobacteria from the Archaean eon.
Where are the earliest fossils found?
In undisturbed strata, the oldest fossils will be the deepest from the surface.
What eon did the paleozoic era come from?
The Paleozoic Era is part of the Phanerozoic Eon. It is the earliest era within the Phanerozoic Eon, spanning from around 541 to 251 million years ago.
Fossils in Precambian rocks are rare while there are many fossils in rocks from the Phanerozoic eon. What does this evidence suggest?
The rarity of fossils in Precambrian rocks suggests that complex life forms were either not abundant or not yet evolved during that time, as the earliest life forms were primarily simple, single-celled organisms. In contrast, the abundance of fossils in Phanerozoic rocks indicates a significant increase in biodiversity and the evolution of complex multicellular organisms, which thrived in various environments. This shift highlights a major evolutionary transition and suggests that the conditions for fossilization and the development of diverse ecosystems became more favorable during the Phanerozoic eon.
What eon did the earliest known rock form?
The earliest known rocks on Earth, dating back around 4 billion years, belong to the Archean Eon. These rocks provide evidence of the formation of the Earth's crust and the beginning of plate tectonics.
Is Sahara some of the earliest human fossils have been found?
No, the Sahara desert is not where some of the earliest human fossils have been found. The earliest human fossils have been discovered in other parts of Africa, such as the Great Rift Valley and South Africa. The Sahara, being a desert, is not conducive to preserving fossils from this early period.
Which of the following types of life is NOT represented in the earliest fossils?
eukaryotes
Fossils of the earliest humans have been found in what country?
The Sahara
What part of the world was the earliest human fossils are located in?
Africa
What marks the end of the Precambrian Eon?
The end of the Precambrian Eon is marked by the beginning of the Phanerozoic Eon, approximately 541 million years ago. This transition is characterized by a significant increase in the diversity of multicellular life forms and the appearance of abundant fossils in the geological record.
During which era did the earth not have a crust?
The Hadean Eon covers the time from accretion to the earliest known rocks.
