A new origin of the ‘modern’ lungfish dentition revealed by taxonomic overlap between Devonian and Carboniferous dipnoans
Lungfishes (Dipnoi, Sarcopterygii) initially radiated in the Early Devonian, and reached the apogee of their diversity during this period, especially with regard to their dentitions. Following the end...

Devonion fishies Elpistostege (close relative of the famous Tiktaalik) and couple of bothriolepis swimming by. Needs updating but still thinking this is one of my better paintings I have done

My girlfriend found this at the store today- a tissue box with stylized #paleoart of prehistoric, pre-Mesozoic sea creatures on it! Very unexpected- features anomalocaris, tremataspis, zenaspis, and dunkleosteus.

Synchrotron CT reveals a slew of gnathostome characters in a jawless fish. Time to rethink the jawless-to-jawed transition for the umpteenth time. Also a much appreciated update to osteostracan internal anatomy.

So we’re just supposed to share our world with these psychos who can bomb & kill anywhere and anytime they want. This is supposed to be our new normal. There is so much more death to come, and we are supposed to be okay with it, or even thankful for the slaughter.

Latest Devonian sagenodontid from Morocco. Further evidence that the Carboniferous-Permian lungfish assemblage (ctenodontids, conchopomatids, sagenodontids, gnathorhizids) all originated by the Hangenberg extinction rather than a single Carboniferous diversification
