Gillicus is a member of the teleost family of fossil fish. It closely resembles a modern day Tarpon and grew to lengths of over six feet long. While Gillicus appears toothless, it actually has microscopic teeth. Unlike its relatives, Xiphactinus and Saurodon, Gillicus was a filter feeder which ate zooplankton, much like modern baleen whales.
