Comparing the geological and fossil records: Implications for biodiversity studies / Сравнение геологической летописи и летописи окаменелостей: Значение для исследований биоразнообразия

A correlation exists between the quality of the rock record and the diversity of fossils recorded from that rock record but what drives that correlation, and how consistent that correlation is across different environments, remain to be determined. Palaeontologists wishing to investigate past diversity patterns need to first address issues of geological bias in their data.
