Here is a interesting cranidium of some sort Odontopleurid. Could this be for example Apianurus???

Cranidium is a very fragile and its widht is ca. 10 mm.

Cranidium is from:
Pooleville member, Bromide fm.
Ordovician, Blackriverian.
Criner Hills, Carter co., Oklahoma, USA.

Hi Jani,

sorry, no idea. For the moment I have the problem, that I can't see the feautures of a trilobite Cranidium.
I know how Apianurus should look like, I found to specimen (Cranidium only) in erratic boulders along the Baltic coast, but on this specimen I can't see the glabella or the characteristic spines from the occipital ring.

The strong tuberculation might be a hint that your fossil might belong to a strong ornamentated trilobite, like some Lichids, but for the moment I can't help.

all the best,
Jens

Mystery is solved. It is a partial cranidium of Apianurus barbatus.

Species is published in 1956 by Whittington; Silicified Middle Ordovician trilobites: The Odontopleuridae. Bulletin of the Museum of Comparative Zoology.
