Taco-shaped arthropod from Royal Ontario Museum’s Burgess Shale fossils gives new insights into the history of the first mandibulates

A new study, led by palaeontologists at the Royal Ontario Museum (ROM) is helping resolve the evolution and ecology of Odaraia, a taco-shaped marine animal that lived during the Cambrian period. Fossils collected by ROM reveal Odaraia had mandibles. Palaeontologists are finally able to place it as belonging to the mandibulates, ending its long enigmatic classification among the arthropods since it was first discovered in the Burgess Shale over 100 years ago and revealing more about early evolution and diversification.

Thanks to #SoftTissuePreservation, we now know what Tuzoia, a Cambrian #arthropod first discovered 100 years ago, actually looked like https://www.livescience.com/taco-lookalike-arthropod-tuzoia

Tuzoia was a predator or scavenger that feasted on the remains of creatures littering the seafloor. The arthropod could likely flex its carapace outward as it moved, enabling its legs to touch the ground and scuttle across it.
