Trilobite fossil age
How to date a fossil. There are two main methods to date a fossil.These are: absolute dating methods that tell us the actual age (in years) of an object. There are many absolute dating methods. A high-resolution 3-D scan of a fossilized trilobite reveals what the ancient marine arthropod ate before it died: shell fragments, bits of sea urchin-like creatures and other bottom-dwellers ...

Such correlation can be on a worldwide scale. Ammonites can be used to distinguish intervals of geological time of less than 200 000 years’ duration. In terms of Earth history, this is very precise.For over a century, this Devonian-age quarry has been noted for its fossil-rich fauna, which in addition to countless pyritized brachiopods and an array of coral calices and crinoid stems, features three trilobite species -- two types of phacopid (Eldredgeops milleri and Phacops rana crassituburculata) and one proetid (Dechenella lucasensis). Fossil evidence shows some trilobites plowed through the seafloor, searching for prey. Trace fossils of trilobite tracks show these hunters were able to pursue and capture marine worms.

Planktonic graptolites, one branch The earliest trilobites had complex, compound eyes with lenses made of calcite. Some trilobites had small eyes or no eyes at all, and probably lived in dark or muddy environments. Trilobites ranged in length from 1 millimetre (0.04 in) to 72 centimetres (28 in), with a typical size range of 3–10 cm (1.2–3.9 in). Indeed, when trilobites of a similar age are viewed together, and then compared and contrasted with other existing specimens, their fossils often provide an unrivalled perspective on the primordial forces that helped shape Planet Earth. Perhaps nowhere is this phenomenon more evident then when dealing with the Middle Cambrian trilobite Paradoxides.
