Overview of the Jurassic Period☆ K.N. Page, in Reference Module in Earth Systems and Environmental Sciences, 2014 Brachiopoda and Bryozoa. Although the last spiriferid brachiopods persist into the Lower Jurassic, the articulate orders Terebratulida and Rhynconellida dominate normal-marine Jurassic brachiopod faunas.Brachiopod assemblages are generally impoverished. Of spiriferids, only Cyrtospirifer kadrlouensis Abramian is present. At the end of the Famennian, the beginning of the formation of the Sphenospira julii–Spinocarinifera nigra zone coincided with the beginning of the first (Etroeungt) wave of the transgressive depositional cycle, which …

The easiest differences to identify are in the shells of clams and Brachiopods. Mollusk shells are divided into left and right while Brachiopod shells are divided top (dorsal) and bottom (ventral). The shells of mollusks are usually equal on the right and left.

Spiriferid are brachiopods filtering feeders that fed on organic particles washed around by the ocean currents. The valves (each shell side) has pronounced folds and sulcus (furrow, fissures). They lived in mud by anchoring to the sea floor with a fleshy stalk called a pedicle that protruded from the shell’s hinge.In the extant articulate brachiopods, the tentacles of the lophophore lack supporting structures such as muscle fibres or bones (Reed & Cloney, 1977; Williams, 1997a). To avoid deflection of tentacles by water flow, a slower internal flow appears to have preferred for feeding in articulate brachiopods (LaBarbera, 1977; Dhar et al., 1997). 3 : Brachiopod^microgast ropod biofacies (98/53A) : A = rhynchonellids, B = spiriferid brachiopod; scale bar 2 mm. 4 : Ammonoids from the microgastropod^crinoid biofacies (A^C natural size, D^G U ...2015. 8. 2. ...

Brachiopod. Brachiopods ( / ˈbrækioʊˌpɒd / ), phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection.

Brachiopod Fossils. The most common seashells at the beach today are bivalves: clams, oysters, scallops, and mussels.
