Fig 4 in The last giants: New evidence for giant Late Triassic (Rhaetian) ichthyosaurs from the UK

Fig 4. Invertebrate and trace fossils found on the bone surface of the BAS surangular, BRSMG Cg3178. A-B. Associated bivalves, including Atreta intrusstriata (A) and Plagiostoma giganteum (B); it is worth noting that a small group of the latter are preserved adjacent to the coronoid process, see Fig 2C. C-D. Examples of the probable scavenging marks that are also observed in the Lilstock surangular, see Lomax et al. 2018, Fig 4. https://doi.org/10.1371/journal.pone.0300289.g004
