@Yara_Haridy Finally, there are some with very multisegmented bodies, which inspired the idea that all Cambrian "bivalved arthropods" were stem-euarthropods. Their position is a bit more controversial, then, but they can have really bizarre carapaces!

@Yara_Haridy Another group are the hymenocarines. These have mandibles, and thus, are probably either stem crustaceans or stem mandibulates (crustaceans and myriapods). We know some of them were already carrying their eggs below the carapace and could also attach to each other in conga lines.
