Description: The Tully monster was a soft-bodied, aquatic creature that lived about 300 million years ago and is Illinois' official state fossil. It was about a foot long with a torpedo-shaped body, a long snout with a claw-like mouth, and two eyes on stalks. While some research in 2016 suggested it was a type of jawless fish, its classification remains a mystery, with other studies arguing for an invertebrate or a completely different lineage I miss them a lot.
