Brachiopod
Absolute age differs from relative age in that it states exactly how old something is, instead of how old it is compared to something else. The age of most fossils, including those of brachiopods, are determined using the carbon dating method.
The Brachiopod is the official state fossil. After lobbying by students and teachers at a Louisville middle school, the Kentucky State Legislature designated the brachiopod the state fossil in 1986; aspecific species was not named. Though they resemble clams, brachiopods are not related to them. There are hundreds of species of brachiopod found in Paleozoic strata throughout Kentucky. They lived attached to the sea bottom or some object on the sea bottom. A few brachiopods survive in the deep oceans today.

Brachipods evolved about 540 million years ago during the Cambrian period. They still exist today, so they also were alive during all of periods between now and the Cambrian.
