Vetustovermis (from Latin: "very old worm")[2] is a soft-bodied middle Cambrian animal, possibly a cephalopod. The single reported fossil specimen is from the South Australian Emu Bay shale.
The original description of Vetustovermis hedged its bets regarding classification, but tentatively highlighted some similarities with the annelid worms.[2] It was later considered an arthropod,[3] and in 2010 Smith and Caron, agreeing that Petalilium was at least a close relative of Vetustovermis (but that treating it as a synonym was premature, given the poor preservation of the Vetustovermis type), placed it with Nectocaris in the clade Nectocarididae.[1]
Early press reports misspelled the genus name as Vetustodermis.
