About This Item

Fish TB, Vertebra Fossilized

The vertebra here is from a fish that was fossilized many years ago...perhaps during the Devonian period, just after the Silurian period, 400 million years ago.

The Phylum Chordata includes only 2% of all animal species: reptile, amphibian, birds and mammals. The remainder of all life on earth has no spinal cord. This distiction made possible a vastly different organization of more motile and efficient killers. The rest of the life on earth is built on more primitive designs and includes insects, mollusks, worms.

The Paleozoic age is divided into 7 periods. Between 2 of these periods ordovician and silurian, green plants differentiated into vascular plant that are more like trees of today and less like algae.

During this time also millipedes first showed up on land and sea scorpions roamed the seas, jawed fishes for the first time swam the seas and whole classes of life became extinct. The trilobite fell pray to the relentless surge of geologic evolution and never again ruled the seas. They are considered the second most famous fossil after dinosaurs and are never found in the fossil record after their Permian extinction event 250 million years ago.

This travel bug is dedicated to a friend and teacher Ula Gaha.
