By integrating our results with developmental data, we propose a new hypothesis for the early evolution of the echinoderm anteroposterior axis. This allows us to reconstruct how the pentaradial body plan of living echinoderms like starfish evolved from a bilaterally symmetrical ancestor.

Our phylogenetic analyses place Atlascystis and other non-pentaradial fossil taxa as stem-group echinoderms, revealing the evolution of the phylum through successive bilateral, asymmetrical, triradial & pentaradial stages.

We describe a new bilaterally symmetrical fossil echinoderm, Atlascystis acantha, from the Cambrian of Morocco. By analysing its growth, we are able to recognize the presence of ambulacra, thereby establishing homologies between bilateral, asymmetrical & radial echinoderms.

Pleased to share a new report, led by @harrysavage.bsky.social, documenting the first evidence of attachment in the Cambrian echinoderm Pahvanticystis. polar.pan.pl/article/item...

For #FossilFriday, I'm delighted to share this amazing new specimen donated to the NHM. The slab preserves over 100 specimens of the Middle Jurassic crinoid Isocrinus nicoleti. This is the subject of ongoing research with Tim Ewin, Ebony Cutcliffe, @egmitchell.bsky.social & @echinerd.bsky.social .

For #FossilFriday, here is a quick volume rendering of a 450-million-year-old fossil starfish from the Lady Burn Starfish Beds of Girvan, Scotland. Scanned by @agneselanzetti.bsky.social at the Natural History Museum.

Very pleased to share our latest paper on simulating the formation of trace fossils, with applications for understanding the colonization of land by animals. Led by Zekun Wang at the Natural History Museum, with Neil Davies, Alex Liu and Nic Minter doi.org/10.1098/rspb...
