The concave valve was so pervasive among strophomenatans that it must have evolved to perform a function, and I conclude that this was to fill with sediment and conceal these animals in their shallow infaunal mode of life.

The Terebratulida, now the dominant group, appeared in the early Devonian and rapidly expanded in the mid-Devonian to produce a number of gigantic forms; a few long-looped and short-looped genera persisted into the Permian. Capable of creating a new organism by combining the genetic material of two gametes, which may come from two parent organisms or from a single organism, in the case of self-fertilizing hermaphrodites.
