An article published in the journal “Papers in Palaeontology” describes the discovery of a species of bryozoan called Jablonskipora kidwellae which constitutes an evolutionary missing link. These are the first modern bryozoans that grew in a structure and their study could help shed light on the evolution of these small invertebrates that live in colonies and are part of a phylum that emerged in the Cambrian period, about 500 million years ago.
