Iridium is a very rare element in Earth's crust, however rocks that have an age equal to that of the K-T boundary are significantly enriched in iridium. It is theorised that this enrichment is due to the impact of an asteroid with Earth (as asteroids are rich in iridium and the resultant massive explosion spread iridium enriched debris all over the world). This asteroid impact is thought to have been a significant event in the mass extinction even that wiped out the dinosaurs.

This is known as the Alverez hypothesis. For more information, please see the related link.
