Are trilobites fossils rare?
Complete trilobite skeletons are relatively rare, and were probably preserved when the sea floor was buried by mud during major storms. Normally, the membranes that hold the skeleton together will decay and the skeleton will fall apart. The various pieces will be scattered by waves, currents or scavenging animals.
How are trilobites fossils made?
Fossil formation is revealed by erosion. Wind, rain, freeze and thaw, even earthquakes will help force the trilobite out of its burial ground and out into the light. If he or she is lucky enough, the trilobite will reveal itself in time to be spotted by a rock-hounder or fossil-digger.
Why are trilobite fossils so common?
Because of their diversity and an easily fossilized exoskeleton, they left an extensive fossil record with some 17,000 known species spanning Paleozoic time. Trilobites have been important in biostratigraphy, paleontology, and plate tectonics research.

Why are trilobites special?
Because they appeared quickly in geological time, and moulted like other arthropods, trilobites serve as excellent index fossils, enabling geologists to date the age of the rocks in which they are found. They were among the first fossils to attract widespread attention, and new species are being discovered every year.
