 Isochrons for Martian Crater Populations of Various Ages
The heavy cratering might be taken a priori as a sign of great age, but we must remember that craters of a few hundred meters diameter can go into saturation in less than the age of Mars.
Figure 12a shows Crommelin crater, in western Arabia Terra that was chosen by Malin and Edgett as an excellent example of exhumed sedimentary layers.
While the lack of craters demolishes the chance for a statistically meaningful fit of crater counts to an isochron, it puts an upper limit on the age – not of the bedrock layers (which may be much earlier) but of the of the exhumation process.

GNS earlier said its study of evidence in New Zealand suggests that the destruction of forests because of the impact winter was largely confined to the American continent, within a radius of several thousand kilometres of the suspected site on the Yucatan Peninsula in Mexico.
Despite its apparent youth, the crater could still be many hundreds of thousands, if not several million, of years old.
