The paleontologist Gavin Young, named the fossil agnathan Pituriaspis doylei after the nicotine-containing drug pituri, as he thought he might be hallucinating upon viewing the fossil fish's bizarre form. The first specimens of P. doylei were empty sandstone casts of the head shields, with none of the original bone remaining.
