I have always been intrigued by scolecodonts (fossil worm jaws/teeth) ever since finding one on a Ordovician road cut back in 2009. When visiting Dr. Conkin one day I saw a jar in his study with jaws similar to fossils I had been finding. As it turns out these were modern day Nereis sand worms. Here are some images of these creatures, there was no label showing where they were found.
While watching the Smithsonian channel I saw a video on Bobbit worms whose jaws seem very similar to the scoledonts found in the Ordovician rock. See this Wikipedia entry on Eunice aphroditois.
