A small fraction of all genera dominate the fossil record.
What is it about?
There are fossil organisms that are familiar to any student who has taken a class in paleontology and that are frequently encountered during even a casual collecting trip to a unit of the right age. In this paper, we have quantified the histories of these dominant genera and compare them to the remaining far more diverse but less common genera.
Why is it important?
Even though dominant genera made up only a small fraction of all genera, the turnover patterns “at the top” closely resembled from the much large datasets that include all genera.
