Like MF1, it also includes skeletal detritus of bryozoan, crinoids, ostracods and
brachiopod shells.
After the opportunistic strategy conducted by Soaresirhynchia bouchardi the distribution of the post-ETMEE
brachiopod assemblages is markedly influenced by the depositional sequences, entailing premature turnovers and involving the earlier record of homeomorphic morphotypes of younger terebratulides and rhynchonellides.

Bioclasts are about 60% and includes predominantly
brachiopods, bivalves and different types and shapes of
brachiopod spines.

The maximum width (mm) of each tagged
brachiopod was measured to the nearest 0.5 mm using vernier calipers.

The present research was aimed at introducing Late Permian
brachiopods in stratigraphic section so as to determine their age and stratigraphic correlation as well as stratigraphically examining the value of recognizing
brachiopod fossils (Figure 2).
Astonishingly, abundance did not help
brachiopod species persist for extended periods outside of the extinction event.
The phosphatized examples, in contrast, are elongate to round in outline and variably 'segmented' or spiriform; one specimen contains numerous
brachiopod shell fragments and was clearly produced by a predator or scavenger.
The
brachiopod shells were examined under a camera lucida and transverse serial sections were obtained by gridding one internal mold with 600 powder on glass plate.
Although the systematic position of that
brachiopod is uncertain, its shell structure is of interest as it differs from those of the other Cambrian lingulate
brachiopods identified in the same region.
