An archeologist or a paleontologist might use little brushes to dust away sand and dirt to expose what she is looking for.
I got to try using some brushes to look for dinosaur bones. The bones were not real, but that was fine because I still really enjoyed this activity for a very, very long time.
This was interesting to me because I have learned a lot about the esophagus and trachea parts in humans and this is definitely different than how human systems are set up!
