I am so unbelievably proud to present 8 years of hard work: the worlds oldest octopus is not an octopus...

Pohlsepia is actually a really rotten Nautiloid (but oldest soft tissue nautiloid ever found!). 🐙❌

We can learn unimaginable amount of things bout the history of life, climate, geosystems and the processes of evolution from the fossil record. But we need strong database curation and financing infrastructure.

Our new paper 'A covarion model for phylogenetic estimation using discrete morphological datasets,' is out in SysBio!
We introduce the "covariomorph" model in RevBayes to capture character and lineage specific rates of morphological traits.

Are interphylum spiralian relationships resolvable? The phyla making up the major animal clade of Spiralia have been clear since the advent of molecular phylogenetics; the relationships between these spiralian phyla have not. The lack of consensus over the relationships between these important animal phyla might be a clue implying their emergence in an explosive radiation. Focusing on the five largest spiralian phyla (Annelida, Brachiopoda, Mollusca, Nemertea and Platyhelminthes) and using two phylogenomic datasets, we have applied site-bootstrapping and taxon-jackknifing to explore this example of taxonomic instability. Analyses on the 105 possible rooted trees relating them showed that interphylum branches are very short. Preference for rooting Spiralia on Platyhelminthes is a long-branch artefact. Most analyses on the 15 unrooted trees showed a preference for the same topology but the support over other solutions was non significant. We conclude that the spiralian phyla emerged in rapid succession resulting in a difficult to resolve radiation. The deep history we infer for Spiralia has wide ranging implications for our interpretation of Cambrian fossils and for the evolution of traits such as biomineralization, segmentation and larvae. Impact Statement Analyses of two independent phylogenomic datasets suggest an explosive radiation at the origin of Spiralia, with implications for understanding the group’s evolutionary history. ### Competing Interest Statement The authors have declared no competing interest.

Exciting news! Our invited perspectives in npj Biodiversity looks at how marine life bounced back after the worst mass extinction ever, the Permian‑Triassic Mass Extinction (PTME) ~252M years ago. Big questions: fast or slow? recovery or restructure?

Our new paper is online! We found that 1) today's shark & ray diversity was already reached ~100Ma; 2) that the K/Pg extinction was not catastrophic; 3) that the max diversity was reached ~50Ma; and 4) that today's diversity is depleted compared to the past.

New paper alert! 🚨 🐌

We studied historic Antarctic fossils from the Zinsmeister Collection to assess whether the K-Pg extinction, as recorded on Seymour Island, was sudden or gradual. We found that benthic life thrived in the 4 million years before the K-Pg.
