In 1984, the paleontologists Raup and Sepkoski argued that there is a cyclical pattern to the extinction events recorded in the fossil record. The pattern implied a 26 million year cycle, itself indicative of an extra-terrestrial cause. There are no known terrestrial causes for such massive and regular extinctions. Could Planet X be to blame, perhaps through showering Earth with comets as it achieves perihelion?
the cycle of these extinction events is to be believed (and
it remains controversial among scientists), then any direct
extra-terrestrial cause must be coincident with that enormous
time-scale. So it would not be satisfactory, then,
to associate a 26 million-year extinction cycle
with a planet whose orbit is measured in thousands of years
only. Nibiru’s relatively short orbit (Zecharia
Sitchin’s ‘Sar’ of 3600 years) could only
produce a random pattern of extinction events on this time-scale.
The 26 million-year cycle would have to be a coincidental pattern, which is an unsatisfactory explanation scientifically.

Tragedy in the Carribean
Sixty-five million years ago about 70% of all species then living on Earth disappeared within a very short period. The disappearances included the last of the great dinosaurs. Paleontologists speculated and theorized for many years about what could have caused this "mass extinction," known, as the K-T event (Cretaceous-Tertiary Mass Extinction event). Then in 1980 Alvarez, Alvarez, Asaro, and Michel reported their discovery that the peculiar sedimentary clay layer that was laid down at the time of the extinction showed an enormous amount of the rare element iridium. First seen in the layer near Gubbio, Italy, the same enhancement was soon discovered to be world wide in that one particular 1-cm (0.4-in.) layer, both on land and at sea. The Alvarez team suggested that the enhancement was the product of a huge asteroid impact.

scientists could have also used Mass
By taking the sample and pulverizing it, heating it and sending the particles through a
Mass Spectrometer they could count each element in the sample.
