Figure 7—1–3, Parapostibulla murphyi; 1, views of the pedicle valve of the brachiopod Composita subtilita with the larger holotype 1890TX1 (left) and the smaller paratype 1809TX2 (right) and several Spirorbis worm tubes. The fracturing of the shell resulted from deformation, rendering the brachiopod dorsal-ventrally compressed, x3.9; 2, enlargement of the holotype 1809TX1. Note that some of the cover plates (most notably along the proximal C ambulacrum) are shifted revealing several floor plates and that the peripheral rim is partly disrupted along the DE interambulacrum, x7.7; 3, paratype 1809TX2. Note the nearly straight ambulacra indicating that this is a juvenile specimen, x7.9. 4–8 Parapostibulla hybolopus; 4, paratype SIU 1502-6. Note the short straight ambulacra of this juvenile specimen, x12.3; 5, specimens of Parapostibulla hybolopus attached to the pedicle valve of the productid brachiopod Antiquatonia portlockianus, SIU1510-1-11, including the holotype SIU1510-7 indicated by the arrow, x2.4; 6, holotype SIU1510-7. Note the lip on the hydro-gonopore and the open aperture, x8.5; 7, paratype SIU1502-3, x7.6; 8, paratype SIU 1502-12, x10.4. Note the slight curvature in the ambulacra

FIGURE 1—Lithology of the Muldraugh Formation hardgrounds. 1, CMC-P2743. Small specimen of Torquerisediscus kypsi n. gen. and n. sp. from surface C. The specimen is attached to a brachiopod fragment along with a spirorbid, whitened, x5.2; 2, CMC-P2702. Specimen of Torquerisediscus kypsi from surface A. Note that the pedunculate zone is fully articulated but the interambulacral areas and ambulacra are completely disarticulated, immersed, x1.25; 3, CMC-P2723A. Hardground from surface C. The right side of the slab has a small cluster of spirorbids attached directly to the surface. The left side has a productid brachiopod incorporated into the surface. The pedicle valve is eroded through appearing as an outline below the specimen. A small specimen of Torquerisediscus kypsi is attached to the interior surface of the brachial valve. In the extreme lower left is a larger eroded specimen of T. kypsi attached to the hardground, whitened, x1; 4, CMC-P2724. Small slab with the holotype of Ulrichidiscus spinosus n. sp. Note that the brachiopod incorporated into the hardground is encrusted by spirorbids and an alloporid coral, whitened, x1.2
