Trilobites occupied marine environments from tropical equatorial to polar
paleolatitudes. Some families of trilobites
were narrow in their requirements. For example,
the family Bathyuridae (Proetida:Bathyuroidea)
was found only in paleoequatorial regions. Trilobite marine niches ranged from intertidal
and nearshore to deep continental slopes.
