Trilobites are also make up a very large percentage of the arthropod fossil record, and the reason for this is that this exoskeleton, the part that you can see in the picture here, was really heavily biomineralized. What that means is that the animal was putting a lot of minerals into its exoskeleton; in this case, calcium carbonate.
