Where was it found?
Marine. Lived across the globe, from China to Rome to the United Kingdom.
Diet and foraging method
This species is extinct, their diet can only be hypothesized. Some think they are analogous to modern crustaceans and therefore were hunter/scavengers, others think they were filter feeders.
Trilobites had compound eyes and thus had one of the most sophisticated visual systems of the animal kingdom in their time.
Social organisation and mating system
Did you know that...?
Collecting trilobite fossils has a long history, some fossils have been found in human burial mounds dating back more than 50,000 years.
