350-410 MILLION YEARS OLD!!! aprox.
This has been varified by Our wonderful Truro Museum, which rely on mainly public funding.
I found this little fossil, amongst many others on The Camel Trail, North Cornwall.
This a Devonian Triobite. The word Trilobite means 3 lobes. They are a well known fossil group of extinct marine Anthropods.
There are around 17,000 known species.
Some species of Trilobites moved on the seabed as preditors, scavengers or filter feeders, although some swam freely feeding on plankton.
Some Trilobites are thought to have evolved a symbiotic relationship with sulphur-eating bacteria from which they obtained food.
