Echinodermata resting place
oilshale posted a fossil in IchnofossilsAsteriacites lumbricalis are five-rayed trace fossils found in marine sedimentary rocks. They record the burrows of ophiuroid and asteroid sea stars on the sea floor. Here in this particular case it can be assumed that these traces originate from Palaeocoma escheri Herr, 1865 (or Ophioderma escheri), a brittle star, whose remains were found to hundreds in situ in the same layers.
