These bivalves are known as pachyodonts.
Description
The thick triangular shell in this genus is capped by a smaller dome-shaped shell. Some of the pachyodonts possessed open passageways through the shell that allowed for fluids to pass. These pachyodont bivalves were habitually sedentary and grew upright with the pointed end anchored in the substrate.[2]
gollark: An important recentish discovery: blue LEDs. Those require exotic materials of some kind, as far as I know, and like all semiconductory stuff large amounts of complex machinery to produce them.
gollark: Is everyone just supposed to have precision manufacturing equipment so they can all try out new inventions randomly?
gollark: Are you just meant to have a basement operation doing highly advanced chemical synthesis or something for, say, new drug testing?
gollark: Also, many modern discoveries are basically impossible without stuff like "laboratories" and "full-time scientists" and supply chains providing the stuff they need.
gollark: As you go over that you probably have to keep adopting more and more norms and then guidelines and then rules and then laws to keep stuff coordinated.
