A beautifully preserved comma shrimp (Pancrustacea: Peracarida) from the Plio‐Pleistocene of Japan and the fossil record of crown Cumacea

open access: yesInvertebrate Biology, Volume 143, Issue 3, September 2024.
Abstract Comma shrimp, or cumaceans, are diverse benthic crustaceans, yet they are one of the groups with the poorest fossil record, hindering our understanding of the evolution of the group in deep time. Here, we describe a new species of fossil comma shrimp, Makrokylindrus itoi sp. nov., from the Plio‐Pleistocene of Japan.
