In human beings, the mouth is the only bodypart that comes equipped with teeth. Well, there are fables of the fearsome vagina dentata and even — top men, beware! — of the occasional anus dentatus. Now the wonderful world of prehistoric nature brings us a penis dentatus. Or so we learn from the latest WIRED.
From WIRED Science, “An Ancient Penis Worm With Rings of Sharp Teeth Has Been Discovered in the Grand Canyon: The 500-million-year-old fossil, containing a species named in honor of the krayt dragons in Star Wars, is a much larger ancestor of phallic marine worms that can be found on the seabed today” by Marta Abba on 8/19/25:
Penis worms are marine creatures with a distinctly phallic appearance. There are more than 20 known species living across the world’s oceans today, as well as a number of extinct ones, like this new discovery. The researcher who made the find was searching for fossils in the Grand Canyon and named the species Kraytdraco spectatus in honor of the huge burrowing krayt dragons that appear in the Star Wars universe. Details of the discovery were published in the journal Science Advances.
