To conclude that a mass extinction had occurred at a certain point in the fossil record, scientists would primarily look for a dramatic change in the number and types of fossils from one layer to the next. This indicates a significant loss of biodiversity and the arrival of new species, which are characteristic signs of mass extinction events.
