Here is a link to a recent publication describing the most complete known fossil primate specimen–Darwinius masillae–from PLoS One. The fossil dates to the early-middle Eocone (~41 million years ago). I would love to write more, however the article is summarizes the findings better than I could with my current schedule. I am very busy preparing for fieldwork. Tomorrow I leave for Ethiopia. My next post will be from the Simien Mountains.
