Diversity of tooth mineralisation patterns at the base of crown chondrichthyans Communications Biology - The study of three in situ preserved chondrichthyan tooth files reveals histological and developmental disparity at the stem of crown chondrichthyans and provides insights...

Our work on the histology and mineralization patterns of 3 Devonian chondrichthyan taxa from Morocco is finally out now! I am very happy to share this work and hope there will be more to come about early shark tooth histology!
Thanks to all my co-authors, especially Hector Botella!

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

A blue unopened box of Kleenex tissues with a pattern of smiling prehistoric sea creatures on it. There is also a fun fact about Dunkleosteus on the top, that it lived 358 million years ago and was as big as a great white shark.

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

Thanks!

Pleased to have played a small part in this paper, led by @aminff.bsky.social Amin El Fassi El Fehri, describing “A new origin of the ‘modern’ lungfish #dentition revealed by taxonomic overlap between #Devonian and #Carboniferous dipnoans” out today in @peerj.bsky.social 🦷🐟 peerj.com/articles/193...

Delighted to have the first paper of my PhD published today in @peerj.bsky.social on a wonderful lungfish tooth plate from Morocco 🐟🦷! With @draliceclement.bsky.social, @merlegreif.bsky.social, & colleagues. peerj.com/articles/193...

As my very first post here on Bluesky I am happy to share our article in Royal Society about tooth wear and diet in the large Devonian chondrichthyan Ctenacanthus concinnus from Morocco
