S2. Original references of analyzed specimens (figure 3 and table 2). from Rostrum morphology and feeding strategy of the baleen whale indicates that right whales and pygmy right whales became skimmers independently

Baleen whales have lost their functional teeth and begun to use their baleen plates to feed on small prey. Modern baleen whales exhibit different types of feeding strategies, such as lunging, skimming and so on. The evolution of feeding strategy in the Chaeomysticeti is an important step in consider...
