There were a few fish of the Ordovician, they were all jawless, and were only simple Chordates; but despite the simplicity, they were an evolutionary miracle, seeing they led to the complex vertebrates.
Some examples would be:
-Astraspis
-Thelodonti
-Pteraspida
-Stroinolepis
What else can I help you with?
When did the diversification of jawless fish occur?
Late Ordovician
Ordovician time period?
The Ordovician was in the Paleozoic era, and lasted from 505 to 438 million years ago. Trilobites were common then, and the earliest jawless, bony fish.
What things live in the ordovician period?
Primitive arthropods, fish, orthocones and sea scorpiond.
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 were the Ordovician mammals?
No mammals existed in the Ordovician
What era is the fish in?
If you are asking what era the fish ORIGINATED, then your answer is the Cambrian Period, which was during the Paleozoic Era (544-245 million years ago). They started off as invertebrates, however. The first vertebrate that was a fish was the jawless fish in the Ordovician period. The first vertebrate that was a fish was the jawed fish in the Silurian period.
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).
What came after the Ordovician period?
The Silurian period followed the Ordovician period.
What period came after the Cambrian period?
The Ordovician period came after the Cambrian period.
What was the climax like during the Ordovician 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.
What type of fish was the earliest to evolve?
lobe-finned fish
How do finger structures provide support for evolution?
All vertebrates, from Ordovician fish onwards, have the same basic limb structure. This implies that they all share a common ancestor.
