The enigmatic Middle Devonian chordate Palaeospondylus gunni from the the Achannaras Slate Quarry, Caithness, Scotland, has recently been reinterpreted as a member of the Cyclostomata (the group that includes living jawless fishes). If this interpret

The well known Middle Devonian (Eifelian–Givetian) lungfish Dipterus valenciennesi from Scotland, UK, has been studied for more than one hundred years though our understanding of the neurocranium and cranial cavity is incomplete. Micro-CT scanning
The Dipnomorpha include the extinct Porolepiformes, in addition to Powichthys and Youngolepis and the extant Dipnoi (lungfish). As sister group to the Tetrapodomorpha, the Dipnomorpha hold a valuable place in our understanding of early sarcopterygian

The enigmatic Devonian fossil Palaeospondylus gunni was identified as a larval form, metamorphosing into the lungfish Dipterus valenciennesi. Morphological features used to identify P. gunni as a larval lungfish include enlarged cranial ribs, rudimen
