| Abstract |
Concretions collected from Motunau and Glenafric
Beaches, North Canterbury, New Zealand, have yielded a
new genus and species of crab, Tongapapaka motunauensis
of the xanthoid family Pseudoziidae and several specimens
of the cancrid crab Metacarcinus novaezelandiae (Jacquinot
in Jacquinot and Lucas), confirming its range from Miocene
to Holocene. These beaches have yielded numerous specimens
of decapod crustaceans, the lobsters and crabs, over the
decades, and the composition of the decapod fauna suggests
an offshore setting for the Greta Siltstone and Mt Brown
Formation exposed at Motunau and Glenafric Beaches, respectively. |
