How did the Phacops rana become extinct?
The Phacops rana, a species of trilobite, became extinct during the end-Devonian mass extinction, which was likely caused by a combination of climate change, volcanic activity, and a drop in sea levels. These environmental changes likely disrupted the trilobite's habitats and food sources, leading to their extinction.
Why is phacops rana a type of trilobite considered a good index fossil to use to estimate the age of a layer?
Phacops rana is considered a good index fossil because it lived during a specific geological period, primarily the Devonian, which allows geologists to date rock layers accurately. Its widespread distribution and distinctive morphology make it easily recognizable and useful for correlating the ages of different rock formations. Additionally, it existed for a relatively short geological time span, enhancing its effectiveness in identifying and dating specific strata.
