Megalodon (bivalve)

Megalodon is an extinct genus of bivalve molluscs that reportedly lived from the Devonian to the Jurassic period.[1] It is not clear, however, that all the fossils assigned to Megalodon from that span of time really belong in the same genus. Jurassic relatives of Megalodon such as Pachyrisma grande were closely related to the rudists.[2]

gollark: Perhaps the answer lies in competition maths problems. Those generally have something weird like the year as a solution, so they could probably be tweaked to 1, right?
gollark: Of course, a smart person would just type it into wolframalpha. I'll check if it accepts this.
gollark: Yes, that.
gollark: Dan just said it had to be a very hard problem which is also hard to understand for laymen with an answer of 1.
