Week Three

This week marks the end of week three of the internship. After reading the article, I learned quite a bit. I have been working with specimens from the late Cretaceous period, and had some backround on the organisms that lived durring that period when reading the article. It is common knowledge that the most accepted theory on how the dinosaurs died is by an asteroid impacting the earths surface. I always believed that the force of the impact is what killed the dinosaurs. However, it is. elieved that the dust that came up after the impact is what actually killed the organisms that were currently living. The dust in the air did many things, incliding make it impossible for plants to photosynthesize. This resulted in 3/4 plant species dying, leaving no food sources for animals like dinosaurs.

The article also taught me that an extraterrestrial body such as an asteroid wasn't the only potential ending to the mass extinction. Researchers have also theorized that there may have been a series of volcanic erruptions where modern day India is. It is important that researchers and scientists continue to develop technologies to more effectively solidify theories on how the dinosaurs met their ending.
