In contrast, trilobite size was strikingly correlated with fluctuations in marine redox (i.e., marine oxygen levels), especially during the well-known anoxic events of this interval.

Our research covers trilobite taxonomy, phylogeny, functional morphology, biogeography, and the refinement of the geological timescale. Trilobites provide an unparalleled sample set for understanding ...

More than 22,000 species of trilobite have been named. This is largely because the trilobite exoskeleton was made of a ...
