       Sidneyia is thought to have been a carnivore of other bottom dwelling marine organisms,‭ ‬scouring the ocean floor and sensing them out with its antennae.‭ ‬So far Sidneyia is known from well over a hundred specimens,‭ ‬with many more likely to yet be found.‭ ‬Individuals ran from about five centimetres to just under thirteen centimetres on length.‭ ‬Sidneyia was named by Charles Walcott in‭ ‬1911,‭ ‬and he named it after his son Sidney who actually discovered the first specimens.
