ああサメの歯は鱗が発展したものなのかとか、
Stethacanthusの頭部もこんなんだったのかとか、
これ何に使うのかとか、思いました。

Hey psst, come here... you like sharks? How's about a shark-ish thing that has a bunch of spikes on its head?
Stethacanthus was a shark relative where the male of the species had bristly little spikes all over its head and hammer-like dorsal fin! Wacky!
Bonus: shark with a mohawk
