considered to be a primitive fish with an elongate eel-like body,
there is no universal agreement into what Palaeospondylus
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.
