ANS: T PTS: 1 REF: 21.4. Paleozoic Invertebrate Marine Life Fusulinids are suspected to have hosted photosymbionts as modern larger benthic foraminifera (Ross, 1972, Shi, 2008, Groves et al., 2012), and their shells may have been used functionally as the greenhouses with the keriotheca honeycomb in the interior wall serving as “pore cups” to hold these symbionts (Shi, 2008). Accordingly, the large ...In summary, the test walls of the studied large, fusiform fusulinids contain two layers with different textures: a microgranular texture making up the main part of the test (keriotheca) and a nanogranular outer lining (tectum).
