First, there is unavoidable imprecision in the laboratory-calculated age.

In ultraclean laboratories, analytical uncertainty can be as low as ±10 years (1 sigma), but in most laboratories, it is of the order of ±50 years (1 sigma).

Plant fossils in growth position on a surface over which a landslide travels are ideal material for dating because the landslide killed the plants; in other words, the ages of the fossils and the landslide are the same, given the aforementioned uncertainties.

Similarly, radiocarbon ages on growth-position fossils associated with a surface directly below lake sediments deposited in a landslide-dammed lake can be reliably linked to the age of the event.

Relative dating methods were the first dating techniques to be developed, and are still widely used.

The radiocarbon dating method was developed in the late 1940's by Dr. Libby, who later won a Nobel Prize in chemistry for this work.

More correctly, the derived ages should be considered “maxima” for the time of the event.

It is possible, for example, that a dated piece of wood recovered from landslide debris came from a dead tree, rather than from a living one.

Care is also required in interpreting radiocarbon ages.Unfortunately, such occurrences are extremely rare. All fossil plant material and bones entombed in landslide deposits are “detrital,” that is, they have been transported to their depositional positions.As such, there is no certainty that the organism was killed by the landslide, which is the conceptual assumption many researchers make when interpreting radiocarbon ages on such fossils.Radiocarbon dating is based on the fact that a radioactive isotope of carbon( Potassium argon dating is an absolute dating technique that can be used on volcanic rocks.
