Mosses (Bryophyta).
The Ordovician period came after the Cambrian period.
The Ordovician period follows the extinction at the end of the Cambrian period.
During the Ordovician period, there was a rapid diversification of marine life, with the development of complex ecosystems and the proliferation of different species. The climax of the Ordovician period was marked by a significant increase in biodiversity, including the emergence of new groups of organisms such as jawed fish and terrestrial plants. This heightened diversity laid the groundwork for the subsequent evolutionary radiations seen in the following periods.
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.
During the Ordovician period, several key index fossils were present, including trilobites like Asaphus and Flexicalymene, brachiopods such as Orthida and Strophomena, and graptolites like Didymograptus. These fossils are significant because they help geologists identify and correlate Ordovician rock layers across different regions. Their widespread distribution and rapid evolution make them excellent indicators of the period's marine environments.
They became extinct in the mass extinction at the end of the Ordovician Period.
The Silurian period followed the Ordovician period.
The Ordovician period came after the Cambrian 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.
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.
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 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.
