Abstract. We know that the fossil record is incomplete. But how incomplete? Here we very coarsely estimate the completeness of the mammalian record in the Miocene, assuming that the duration of a mammalian species is about 1 Myr and the species diversity has stayed constant and is structurally comparable to the taxonomic diversity today. The overall completeness under these assumptions appears to be around 4%, but there are large differences across taxonomic groups. We find that the fossil…

Life rather than climate influences diversity at scales greater than 40 million years.
The diversity of life on Earth is controlled by hierarchical processes that interact over wide ranges of timescales1. Here, we consider the megaclimate regime2 at scales ≥1 million years (Myr). We


Completeness of the mammalian fossil record in the Iberian Neogene
It is concluded that the mammalian fossil record from the Neogene of the Iberian Peninsula is very complete, being a good indicator of how complete the record of terrestrial organisms can be at least under certain favorable conditions.
Absolute measures of the completeness of the fossil record
Quantitative, widely applicable absolute measures of completeness at two taxonomic levels for a broader sample of higher taxa of marine animals than has previously been available are presented and it is found that completeness is rather high for many animal groups.
Completeness of the eutherian mammal fossil record and implications for reconstructing mammal evolution through the Cretaceous/Paleogene mass extinction
The completeness of the eutherian fossil record through geological time is evaluated and supports the “explosivemodel” of early placental evolution, whereby placentalmammals originated around the time of the K/Pg boundary and diversified soon after.
How good was the fossil record? Clues from the Californian Pleistocene
The living members of 113 families of bivalves and gastropods of the Californian Province include 698 species living at shelf depths, of which 538 or 77% are known as Pleistocene fossils from the
Global Completeness of the Bat Fossil Record
It is suggested that 88% of bats that existed never left a fossil record, and that the fossil record of bats is indeed poor.
Completeness of the known graptoloid palaeontological record
Using a high-resolution chronology of graptoloid first and last appearances, we apply mathematical models that allow the simultaneous inference of the probability distribution of species durations
Fossil preservation and the stratigraphic ranges of taxa.
The higher estimates of completeness at smaller geographic scales support previous suggestions that the incompleteness of the fossil record reflects loss of fossiliferous rock more than failure of species to enter the fossilrecord in the first place.
Quality of the fossil record through time
It is shown that new assessment methods, in which the order of fossils in the rocks (stratigraphy) is compared with the order inherent in evolutionary trees (phylogeny), provide a more convincing analytical tool: stratigraphy and phylogeny offer independent data on history.
Miocene Hominids and the Origins of the African Apes and Humans
It is suggested that the last common ancestor of chimpanzees and humans was morphologically unique, but more chimpanzee-like than hominin-like: a knuckle-walker with a chimpanzees-sized brain, canine sexual dimorphism, and many probable behavioral similarities to living chimpanzees.

The fossil record was already well known 150 years ago, when Charles Darwin published On the Origin of Species, and it is central to Darwin's theories; yet it is commonly claimed that the fossil record is woefully incomplete.
