“…Divergence ages of the clades were estimated by BEAST 2.7.3 [20]. Optimized relaxed clock and Yule models were applied with eight fossil calibration points as prior settings (table 1) according to [21][22][23][24][25][26][27][28][29][30][31][32] shown in figure 2. Details of input into BEAST for the fossil calibrations can be found in electronic supplementary material, table S3.…”

Understanding how animals evolve to become parasites is key to unravelling how biodiversity is generated as a whole, as parasites could account for half of all species richness. Two significant impediments to this are that parasites fossilize poorly and that they retain few clear shared morphological features with non-parasitic relatives. Barnacles include some of the most astonishingly adapted parasites with the adult body reduced to just a network of tubes plus an external reproductive body, but how they originated from the sessile, filter-feeding form is still a mystery. Here, we present compelling molecular evidence that the exceedingly rare scale-worm parasite barnacle Rhizolepas is positioned within a clade comprising species currently assigned to Octolasmis , a genus exclusively commensal with at least six different phyla of animals. Our results imply that species in this genus-level clade represent an array of species at various transitional stages from free-living to parasitic in terms of plate reduction and host-parasite intimacy. Diverging only about 19.15 million years ago, the route to parasitism in Rhizolepas was associated with rapid modifications in anatomy, a pattern that was likely true for many other parasitic lineages.

“…Archaeolepas has a relatively small number (10) of large, robust peduncular plate columns. Descendants of these survived into the Cretaceous (Bosquetlepas and Myolepas), specializing in living intertidally, and developed powerful retractor muscles to hold themselves down on rocky substrates (Gale and Sørensen, 2015).…”

“…Microborings, which are more abundant on capitular cirripede plates from the BCB, are developed as small connected channels and could be caused by algae, hydroids, fungi or even clionid sponges. Similar data of predation on cirripede valves are poorly known, e. g. from the Campanian locality Ivö Klack in southern Sweden (Gale & Sørensen 2015).…”
