The whole digestive system of the Cambrian arthropod Sidneyia inexpectans is reconstructed.
- •
It has 3 pairs of digestive glands and an abdominal pocket in which food remains are concentrated.
- •
Sidneyia fed on trilobites, brachiopods, possibly agnostids, worms and undetermined animals.
- •
Sidneyia was a durophagous, non-selective carnivore with predatory and/or scavenging habits.
