Although the paper is officially published this Friday, some of you have already found out about it, so I cannot keep it secret any longer. Here is the newest bivalved #arthropod from the Burgess Shale: Balhuticaris voltae. (1/8)

Link: cell.com/iscience/fullt… Balhuticaris belongs to a group of 500 million-year-old carapace-bearing arthropods known as hymenocarines. We think that hymenocarines are probably early mandibulates, the group that contains crustaceans, myriapods and insects, although there are still some debates about it.
