I will trade these fossils for one well preserved European goniatite or European triassic ammonite (specimen with 5 to 8 cm preferentially) because that kind of specimen is lack in my teaching collection. Note the Anorthopygus orbicularis is not a common species and, apart the incomplete test, has an exceptional detailed preservation, rarely seen. 

Best regards,

Ricardo

Anorthopygus michelini Cotteau, in Cotteau & Triger, 1860

Other Very rare species. Specimen unprepped, it could be much better after that, but not perfect because it misses the periproct area. Differs from Anorthopygus orbicularis in being much more conical in profile.

New one

Interesting specimen of Anorthopygus orbicularis (note that it was treated with wax) with organisms encrusted on the test (not really epibionts). Black and white image to improve the visualization of encrusted organisms. I will trade this fossils for one well preserved European goniatite or European Triassic ammonite.
