Author biographies Plain-language and multi-lingual abstracts PDF version. Biomineralised exoskeletons of trilobites are ideal for recording abnormalities, documenting injuries from failed attacks, and understanding predation in the fossil record. The illustration of new injured Cambrian-aged trilobites is particularly important for elucidating aspects of early Paleozoic predator-prey systems and identifying groups that were targets of this early predation. We document six new abnormal trilobite specimens from the Royal Tyrrell Museum of Palaeontology, including the first evidence for injuries on the corynexochid trilobite Hemirhodon amplipyge. These new data highlight the importance of museum collections in uncovering unique and informative specimens for studies of predation on early animals. Russell D. Brayden Holland.

Boulder, CO, USA – The meters-long, carnivorous “shrimp” from hell that once ruled the SOFT-FOOD of ANOMALOCARIS a half billion years ago may have been a real softy, it turns out.
