Brachiopods have one of the longest histories and best fossil records of all invertebrates. They lived in the mud or were attached to the sea floor, filter-feeding on organic particles carried by ocean currents. Their fossils are mostly found in muddy sediments, such as the Wandrawandian Siltstone around Ulladulla Harbour.Although the last spiriferid brachiopods persist into the Lower Jurassic, the articulate orders Terebratulida and Rhynconellida dominate normal-marine Jurassic brachiopod faunas.

Open-ended tubes were found extending inward from the inner surfaces of brachial valves of three different species of Emsian spiriferid brachiopods. It is believed that these tubes were formed by the outer epithelium of the brachiopods, precipitating shell material around a small commensal filter feeding organism living in the outer mantle cavity. Computational fluid dynamics simulations were performed to examine the passive recruitment of epibionts onto Devonian spiriferide brachiopod host shells.
