       Usually considered to be a primitive fish with an elongate eel-like body,‭ ‬there is no universal agreement into what Palaeospondylus actually was.‭ ‬In the past Palaeospondylus has been proposed to be a larval lungfish,‭ ‬unarmoured placoderm,‭ ‬ an arthrodire,‭ ‬a chimaera and even a larval tetrapod.
       A primitive fish that might be similar to Palaeospondylus in form,‭ ‬and also known from Scotland,‭ ‬is Jamoytius.
