Fossils of fish appeared approximately 500 mya during the what?
Fossils of fish appeared approximately 500 million years ago during the Cambrian period. This period saw the rapid diversification of life forms in the oceans, including the development of early fish species.
What period came after the Cambrian period?
The Ordovician period came after the Cambrian period.
Where and when did the first plant evolve?
Fossils of the earliest land plants come from the Ordovician period (roughly 450 million years ago).
Was their an ice age in the Ordovician period?
Yes, it is believe that there was a glaciation at the beginning of the ordovician, and posibly one nearing the end. It is generally thought to be a period of tropical temperatures, and high sea levels.
The Ordovician period follows the extinction at the end of which period?
The Ordovician period follows the extinction at the end of the Cambrian period.
Index fossils include ostracoderms?
Ordovician Period
What period did life move to land?
The period during which life began to move on land was the Ordovician Period. It was during this time that evidence of plant spores from living fossils were found on land.

What first evolved during the Ordovician period?
During the Ordovician period, the first land plants evolved, as well as the first jawless fish, jawed fish, and arthropods like trilobites. This period also saw the emergence of the first coral reefs.
What was the largest landmass during the Ordovician period?
During the Ordovician period, the supercontinent Gondwana was the largest landmass on Earth. Gondwana included parts of present-day Africa, South America, Antarctica, Australia, and the Indian subcontinent.
What is the dominant plant of the Ordovician period?
Algae was the dominant plant of the Ordovician. There were little to no other plants (other then algae) during the Ordovician. In the Ordovician, the common types of algae were Stromatolites (Blue green algae), and Tetradium (Red algae).
The Ordovician period follows the extinction at the end of which period?
The Ordovician period follows the extinction at the end of the Cambrian period.
Where was New York State located during the Ordovician Period?
During the Ordovician Period, which lasted from about 485 to 444 million years ago, New York State was situated near the equator in a shallow marine environment. The region was primarily covered by a warm, shallow sea, leading to the deposition of sedimentary rocks rich in marine fossils. This period saw significant geological activity, including the formation of limestone and sandstone deposits that are prominent in New York today.
