The drillhole at CRP-3 was the deepest of the project and offered early hopes of retrieving a long plalaeontological record. However, the reality was that the fossil
content dropped off markedly in the lower half of the hole, leaving some tantalising unknowns and uncertainties concerning palaeoenvironments and biochronology. Thus,
authors agree that the age of the bottom of CRP-2/2A is early Oligocene, as is the top of CRP-3, but the amount of possible overlap is debatable and even slight underlap is
likely. Likewise, despite some palaeontological hints that the lower part of the Cenozoic sequence could be within the topmost Eocene, just how much is uncertain.
