In case you missed it, there was a paper in Biology Letters last week that
announced the finding of the oldest known animal sperm found in a worm
cocoon, most likely from a branchiobdellid.
You can read the article here: (Biology Letters:
http://rsbl.royalsocietypublishing.org/content/11/7/20150431).
Also the write-up about the article in National Geographic (
http://news.nationalgeographic.com/2015/07/150714-fossilized-sperm-found/)
and Smithsonian magazine (

Enjoy!
