The more slowly an organism is buried with sediment after death, the more likely it is to become a fossil. B. Organisms with hard parts made of shell or bone are more likely to become fossilized. C. Low-energy environments are not suitable for preserving fossils. D.Abstract. Trilobites offer one of the best fossil records of any arthropod group. This is due to a number of factors, most notably the combination of (1) having inhabited areas where organisms are more likely to be buried and ultimately fossilized; and (2) having had a highly biomineralized exoskeleton more likely to survive the stresses of fossilization.Despite the huge abundance these diverse animals in our fossil records, much of their basic biology is still unclear, like what they ate.
