2. Now, look for a card that has either a "T" or "C" written on it. Since this card has a common letter with the first card, it must go on top of the "TC" card. The fossils represented by the letters on this card are "younger" than the "T" or "C" fossils on the "TC" card which represents fossils in the oldest rock layer.
Brachiopods have little pontential for defence, being vulnerable to a broad spectrum of epibiont, especially fast growing ones. Taxa with punctate shell seem to have more protection against epifaunal attachment than those without punctae, although, for example, adult Megerlia truncata and Terebratulina retusa may have numerous epibionts over their …The brachiopod which the shell represents grew for a number of years, but eventually died. At this point the two valves of the shell may have become separated, ...Starting about 250 million years ago, at the end of the Permian period, brachiopod groups disappeared in large numbers, along with 90 percent of the planet's species.

Brachiopods feed on minute organisms or organic particles. Articulate brachiopods, which have a blind intestine, may depend partly on dissolved nutrients. Shells of some articulate brachiopods have a fold, which forms a trilobed anterior that helps keep lateral, incoming food-bearing currents separated from outgoing, waste-bearing currents.
With very few living representatives, brachiopod classification has primarily come from a paleontological perspective, with substantial consideration given to the morphology of the shell. Traditionally, brachiopods have been separated into two major groups: the Inarticulates (brachiopods with phosphatic shells) and Articulates (everything else).Brachial (dorsal) valve: the smaller half of the shell, which supports the …
