Mississippian
Brachiopods are one of the most abundant group of invertebrates in the fossil record. These filter
feeders have been around since the earliest Cambrian and although rare still survive today. They
reached their zenith in the Palaeozoic period, but at the mass extinction at the end of the Permian
they never recovered to their former level of diversity and were rapidly replaced by the bivalves.

The brachiopod animal lives within a pair of shells (valves), much like a modern day clam, but has a
body form that is significantly different thereby placing them in their own phylum.

The earliest Cambrian forms are typically small and simple, but throughout the Ordovician and
Silurian they rapidly diversified. Although some are known from these periods, it was during the
Devonian that the number of medium and large species reached a peak. (Faunas from New York,
Ohio, Morocco, Oklahoma and Tennessee are all characterised by this enlargement in comparison
to those seen in the Silurian).

Brachiopod faunas worldwide were hit hard by the Devonian mass extinction events and although
they persisted for another 100 million years through the Mississippian, Pennsylvanian and Permian
they remained consistently small and notably less diverse in morphology. Of the groups that
remained 90% went extinct with the Permian extinction.

There was a recovery in the Jurassic where some medium sized forms appeared, and although they
persisted through the period the bivalves had been able to better adapt to the post extinction seas
and filled many of the niches once filled by brachiopods. With the end Cretaceous mass extinction
the brachiopods faced yet another challenge but were able to endure and can still be found in
oceans today.

With more than 500 million year of history, brachiopods are an important index fossil and present a
vast array of forms for the collector.
Offered below is a large selection of brachiopods ranging from the Cambrian to Cretaceous.
