How I make a difference

In my internship, I clean and organize microfossils that came from an expedition from Ellen Thomas somewhere around 1980's. What I do is important because, when the mud is finally off the fossils, people can now study them and be able to tell what time period the fossils came from and what the climate was around that time. My PI is a new mother right now, so I haven't been able to talk to her about the work I'm doing, but I know it's very important since Ellen Thomas, the person's whose forams we are cleaning told us that we were part of a big help.
