It is also reported that they are susceptible to Narcissus bulb flies. 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. The collection of such fossils from different rock formations and layers enables the geologists to identify the layer of rock they were found in. Characteristics This is because they allow geologists and paleontologists to find the fossil age by examining the relationship of a particular fossil with another event of a specific period.

That is, if a fossil from an unknown period is found near a fossil from a known one, it is assumed that the two species belonged to the same time. Because of its narrow time range, Tropites is a good index fossil (useful for stratigraphic correlations). The rocks should be carbondated to determine which is older. This genus is present from the Jurassic to the Cretaceous periods. Beds that preserve fossils typically lack the radioactive elements needed for radiometric dating.This technique is our only means of giving rocks greater than about 50 million years old an absolute age, and can be accurate to within 0.5% or better. Furthermore, index fossils are classified into three different eras; namely, Cenozoic, Mesozoic, and Paleozoic.
