Cambrian evolutionary radiation: context, correlation, and chronostratigraphy—overcoming deficiencies of the first appearance datum (FAD) concept

E Landing, G Geyer, MD Brasier, SA Bowring - Earth-Science Reviews, 2013 - Elsevier
Use of the first appearance datum (FAD) of a fossil to define a global chronostratigraphic
unit's base can lead to intractable correlation and stability problems. FADs are diachronous …
