Scratching My Head

[FrozenInTime]

Hi people,

I recently came across pictures of this fossil on the internet, with an interesting story on determination that was apparently done by our members in the past:

I find it quite amusinginteresting to see that this has been identified as a Ceraurus, and is said to be from the Ordovician?

Would anyone agree with me that this is more likely to be a proetid from either the Permian or Carboniferous period, and because it's from Mississippi, it is likely that - ironically enough - a more exact age could well be Mississippian.

Does anyone know more about the above story?

The fossil itself looks pretty interesting, apart from the wrong ID.
