Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. A substantial hurdle is the difficulty of working out fossil ages. Some typical Despite these advances, we still know relatively little about how development constrained or contributed to trait evolution in trilobites, and almost nothing about the origin of novel traits in trilobites.

In the latter case, trait evolution could still occur through modification of rates of morphological change along otherwise conserved ontogenetic trajectories. Index fossils are used to identify geologic periods, which is why they are also known as guide fossils or indicator fossils. It is said that the very small fossils have proven to be the most useful for dating purposes.

Long-term clade-wide shifts in trilobite segment number and allocation during the Palaeozoic. This era is considered as the age of ancient life. At the clade level, the pattern of expression and release of new exoskeletal segments during post-embryonic development was generally conserved across most species, but the relative timing of different segmentation events could vary, and developmental traits appear to have been relatively labile across the clade's evolutionary history.
