Baculite

Baculites are cethalopods with straight shells. They existed 200MYA. They were able to glow in the dark.

The biggest Baculite was 6ft. long, but most were 4ft. long.

They had the same eating habits as Cuttlefish do today. They catch small animals with their tentacles and rip up their prey with their beack.

They were mostly found in the Western part of America.
