∙ 10y agoTrilobites are an entire extinct class. Within the arachnid class, eurypterids (giant sea scorpions) have been gone since the Devonian, and a little while later in the insect class griffinflies (giant dragonflies such as Meganeura) followed suit. That's the most prominent vanished groups. :)
