Fig. 3 in Trepostome bryozoans encrusting Silurian gastropods: A taphonomic window and its implications for biodiversity

Fig. 3. Thin sections of trepostome bryozoan Homotrypa cochlea sp. nov. from Upper Leintwardine Formation; Ludfordian, upper Ludlow, Silurian; Delbury Quarry, Shropshire, UK. A. NMW 2019.21G.5.2, encrusting colonies comprising multiple layers caused by self-overgrowths (A1), apex of gastropod shell encrusted with bryozoan colony (A2), colony does not grow over the gastropod shell aperture (A3, A4). B. NMW 2019.21G.6.2, colony encrusting apertural side of shell thinner than on the abapertural side, arrow indicates Trypanites boring in bryozoan colony. C. NMW 2019.21G.7.3, colony can be seen inside the aperture of gastropod shell.
