The specimen is a partly preserved atlas from an elasmobranch measuring 14mm times 9mm. Both the cranial and the caudal ends are well preserved with articular facets, whereas both the neural arch and the "transverse process*" are broken. It is not possible to taxonomical identify the specimen at the present stage, but further studies might encircle it. A preserved atlas has not been observed before and with well preserved tesserae (not to be confused with dermal bone tissue in ostracoderms and placoderms) makes this specimen unique I propose this tooth being declared Danekræ.
* There are substantial differences between the atlas and all the remaining trunk vertebrae, which do not possess transverse processes and in lack of terminology I have used the term transverse process!
