Advanced notes
Because of the bilateral symmetry and preservation at first glance this could be mistakenly identified as a brachiopod. Other specimens, with different preservation, show that this is in fact a bivalve, and once you have seen enough of these you will know that Dunbarella is a bivalve not a brachiopod.
