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.
