The hidden pattern of the primary teeth in an ancestral ray-finned fish provides a clue to how the strange lungfish dentition could have evolved simply by modifying the growth mode of bone. More information in this newly published piece from @uuvertpalaeo.bsky.social here: doi.org/10.1111/joa....

Continuing our celebration of #fossilfriday, Maíllo and colleagues perform osteohistology of an ornithopod from Aliaga (Spain), finding it matured at ~7 years and died aged 9–12. This first use of the three-front model in an #ornithopod reveals strong bone-to-bone variability doi.org/10.1111/joa....

These findings are important because they contribute to a growing body of evidence that many of the mammals that took over ecosystems from the dinosaurs were similar in lifestyle to those living today. onlinelibrary.wiley.com/doi/10.1111/...

By cutting the bones to reveal #cellular signals of growth, they found that this species grew much like living placental mammals (as opposed to marsupials). It reached close to full size in one year, and then lived for 3–4 years afterwards.

Growth patterns of an #extinct #mammal that lived just after the extinction of the #dinosaurs were studied. This particular species, Conoryctes comma, is important because its relatives are one of the only groups of mammals known from fossils both before and after the #extinction.

📰 Cranial scans in South Africans revealed higher facial asymmetry in female and Black individuals, especially in nasal and temporal regions. These shape shifts may not skew IDs but should be considered in anthropological analyses of ancestry, health, and human variation 📰:
