They're actually from down under, so yeah it makes sense. Aussies do grow up hearing more about Gondwana than Americans do, very generally, because as this post began with, present day Australia has a Gondwanan legacy.

And King Gizzard are generally scientifically and intellectually curious . . . their lyrics are filled with clever bits of scientific and mathematical lacuna, viz "Tetrachromacy" and clever lines like "I am everyone and every zero."
