|  Description:
The Ctenacanthids are named for Ctenacanthus, a genus erected
by Louis Agassiz based upon a distinctive spine whose name means “comb
spine”. Note the excellent skin details and spines preserved
here. I disagree with the assignment and feel this one is far
more likely to be an acanthodian. Regardless of the correct placement,
this is a fine example.
