In this approximately 3000 word article, we will provide an in-depth overview of major groups of fish that lived during the Paleozoic Era.

The fossils of these ancestral fish date as far back as the Middle Jurassic period, which took place about 170 million years ago.

For decades, the coelacanthexisted only in fossil records—until one turned up in a South African fishing net. It was 1938 when a museum curator in East London noticed an unfamiliar fish in a ...
