Trilobite appendages

Schematic drawing of a trilobite segment with appendages in cross section. This conceptual drawing is the result of an interpretation of a number of (partial) reconstructions in literature and well-preserved fossils of trilobite limbs.

Dorsal morphology

Overview of mayor dorsal features of the trilobite exoskeleton using two examples with a distinctly different morphology, illustrating how a similar body plan can produce very distinct forms. This was key to the enormous adaptive capacity of trilobites troughout their evolution.

Stratigraphic chart

 Stratigraphic chart, to scale. Based on data and standards of the ICS. The animal diagrams are indicative for the taxonomic diversity of some iconic taxa, including trilobites. The graph includes a chart of approximate extinction rates, highlighting major extinction events. Age indications are in millions of years.
