Stethacanthus was an odd,
dogfish-sized shark of the Carboniferous Period, about 320 million
years ago. The brush-like dorsal fin with enlarged denticles on its
flattened top and corresponding denticled patch on top of its head
have generated much speculation about their possible function. I
join in this 'game', suggesting a new possibility for how this weird
structure may have been used.
