A HISTORY OF NOTTINGHAMSHIRE 



No record of fish remains appears to exist from the Permian of the 

 county, but about twenty years ago there were discovered in the roof of 

 a coal-seam in Clifton Colliery teeth, spines and vertebras of large fishes. 

 The spines were reported to resemble those of the Palaeozoic genera 

 Ctenacanthus and Gyracantbus, but it does not appear that any proper 

 description of the specimens has ever been published.
