Benthic foraminifera are useful for correlation and dating of Paleozoic through Recent marine sedimentary rocks.

Question

Quizplus · Accepted Answer

Benthic foraminifera are single-celled organisms that live in marine sediments, and different species have evolved at different times throughout Earth's history. By studying the fossil assemblages of benthic foraminifera in sedimentary rocks, geologists can often determine the age of the rocks and correlate them with similar rocks in other locations. This makes benthic foraminifera important tools for paleontological and stratigraphic research.
