White and Megatooth Sharks
Figure 7
Crustacean remains and burrows from the Middle Eocene (Lutetian) gravels at Dalum. (1) Burrows by crustaceans, with large burrows of Ophiomorpha isp. and other smaller burrows in bioturbated glauconitic sands of the Fürstenau Fm. at the Osteroden sand pit (see also burrows in Figure. 3(d)). (2) Refilled Ophiomorpha isp. burrow fragment, phosphorite concretion (SCB no. Invert-41). (3) Encrusted Ophiomorpha isp. burrow fragment, phosphorite concretion (SCB no. Invert-38). (4) Refilled burrow fragment, phosphorite concretion (SCB no. Invert-40). (5) Triaxonic burrow fragment, phosphorite concretion (SCB no. Invert-39). (6) Abdomen fragment from the lobster Hoploparia sp., phosphorite concretion (SCB no. Invert-14), dorsal. (7) Carapace of the lobster Hoploparia sp., phosphorite concretion (SCB no. Invert-16), lateral. (8) Lower pincer of the lobster Hoploparia sp., phosphorite concretion (SCB no. Invert-13), lateral. (9) Crab Zanthopsis large right pincer, phosphorite concretion (SCB no.
