It's the brachiopods!The Sinnipee Group is a geological group in Wisconsin. It consists primarily of sedimentary carbonate rocks. Primarily made of dolomite, it also has limestone as a secondary component and can even have shale imbedded with it.

Brachiopod belongs to phylum Brachiopoda. It has a shell with unequal two valves. On the other hand, bivalve belongs to phylum Mollusca and has a shell with equal two valves. Furthermore, brachiopods live only in marine habitats while bivalves live in both marine and freshwater environments. How can you identify a brachiopod?Brachiopods. Brachiopods are rare in modern oceans, but were very common in the past (only 325 living species but more than 12,000 fossil species).

Even though brachiopods are among the most significant components of the marine fossil record by virtue of their considerable diversity, abundance, and long evolutionary history, fewer than 500 species are extant. Reconciling ...Brachiopod fossils have been useful indicators of climate changes during the Paleozoic era. They do look rather like bivalves, but their internal organisation is quite different.
