Reconstruction of an orthocerid nautiloid by Nobu Tamura.

Thus, large compound eyes made up of thousands of facets allowed the super-predator Anomalocaris to spot and track its prey.

Thus, Anomalocaris may have been feeding on soft-bodied organisms including on freshly moulted "soft-shell" trilobites (Rudkin, 2009).

Henriksen (1928) attached Anomalocaris to the carapace of Tuzoia, but Briggs (1979) suggested instead that it was the appendage of an unknown arthropod, an idea that turned out to be correct.

Exceptionally preserved soft-bodied fossils of the Cambrian predator and stem-lineage euarthropod Anomalocaris canadensis from the Burgess Shale, Canada.

Much to his surprise, Whittington uncovered two Anomalocaris “shrimp” attached to the head region of a large body, which also had the “jellyfish” Peytoia as the mouth apparatus.

One of them, Anomalocaris “strange shrimp” measuring more than one meter in length was a giant hunter suitable for swimming and catching prey.

articulated specimens of Hurdia (allowing the animal to be reinterpreted as a smaller relative of the largest predator known in the Cambrian, Anomalocaris), and

The creature is related to Anomalocaris, a vicious prehistoric fish whose relatively large size and toothy mouth earned it the nickname "the T. rex of the Cambrian".

This technique proved so successful that it was used in all subsequent studies, leading to spectacular discoveries like the true nature of the animal Anomalocaris.

Based on the latest Museum research, long-extinct animals such as the whimsically-built Opabinia, the fearsome-looking Anomalocaris and the spiny, worm-like Hallucigenia will be brought vividly alive in a fully immersive encounter.

The anomalocaridids could have fed by grasping one end of the trilobite in the mouth apparatus and rocking the other end back and forth with the frontal appendages until the exoskeleton cracked (Nedin, 1999).

Collecting at the Burgess Shale by the Royal Ontario Museum in the early 1990s led to the discovery of several complete specimens, which Collins (1996) used to reconstruct Anomalocaris canadensis with greater accuracy.
