Anomalocaridids are iconic Cambrian animals, originally found in the Burgess Shale deposits in Canada. From the Genus Anomalocaris, their name translates as 'strange shrimp' owing to their initial misidentification from incomplete remains. In fact, it took until 1985 to realise that three different animals were all actually disarticulated parts of the same animal! Our knowledge of these enigmatic creatures has increased exponentially in recent years owing to many exciting new fossil discoveries, as well as reanalysis of old specimens using new technologies. Researchers are building up a picture of a group of animals far more diverse than previously expected, including apex predators as well as possible filter feeders and scavengers. Their temporal range is surprising too - they survived the end Cambrian extinctions when many other taxa died out, and many questions about their ecology, relationships and extinction remain to be answered.
