Found this on the beach at Trouville-sur-Mer in France, on 11 May 2018. It was laying in the sand, close to a trash can. Considering the strong smell of sand within the skeleton, it must have been near the sea for a very long time.


What species is this from?

Also posted on other identification websites and fora:


The length of the bone (the piece remaining) is under 12 centimeter.

The height of the only easily removable tooth (the smallest remaining one) is under 25 milimeter.

  • $\begingroup$ Can you do a close up shot of the teeth from above, so we can see the crown layout, that is one of the main ways to identify mammal material. $\endgroup$ – John Jul 16 '18 at 15:39
  • $\begingroup$ Sasquatch for sure :p. $\endgroup$ – theforestecologist Jul 17 '18 at 1:42

It would be great to have a scale bar in the photo, so that the size would be easier to determine. However, by the shape of the teeth, I will propose that it is the back half of the jaw of a pig. Here is an image from the National Maritime Museum:

Pig

This one is from Vanuatu and has a rather elaborate mesial portion of the jaw, but the teeth look very similar. It's virtually impossible to know the bone's age or species, however.

  • $\begingroup$ Thank you for your answer. Yes, posting these images on Identification apps/websites/fora, I also became aware of the usefulness of a scale bar. Within a couple of weeks, I can take high-resolution pictures with a scale bar. --- Do you think any conservation archive, museum or researcher could be interested in analysing or conserving the specimen? How would I be able to find such an interested party easily? $\endgroup$ – Vincent Mia Edie Verheyen Jul 16 '18 at 14:19
  • $\begingroup$ without knowing what rock it came out of there is not a lot that can be done scientifically with what you have. Although someone might be interested in trying to figure out where i eroded out from. Contact the nearest natural history museum. $\endgroup$ – John Jul 16 '18 at 16:00
  • $\begingroup$ I agree with @John. Without additional provenance information, it's not much use scientifically. However that does not mean that a local museum would not be interested in it for display. $\endgroup$ – kmm Jul 16 '18 at 16:45
  • $\begingroup$ @kmm I have added new pictures, which show the bone with teeth from above and also feature a scale bar. Please update your answer if appropriate. $\endgroup$ – Vincent Mia Edie Verheyen Jul 23 '18 at 12:11
