Hello everyone!
I have recently purchased this skull roof from an actinolepid placoderm from the lower Devonian of Ukraine,
The fossil was labelled as Kujdanowiaspis, but there is also a closely related genus found there called Erikaspis.
I have been looking at several papers to try and see what distinguishes the two and if it is possible to tell what mine is but right now I am not sure.
Any help identifying the genus and even species if possible would be great,
Thank you
