#morphometric — Public Fediverse posts

🌍 Geographic & evolutionary significance: Geometric #morphometric analysis places 𝘗𝘰𝘭𝘰𝘯𝘰𝘭𝘪𝘮𝘶𝘭𝘶𝘴 among the most morphologically extreme austrolimulids, most similar to forms from #australia. This extends their range to Central Europe and reveals Triassic xiphosurids were already widespread by the Early #Triassic, suggesting rapid post-Permian #diversification or earlier dispersal.

New article out today in #Scientific #Data: Lewandowski et al. (2025) present the #Apemen #Faces #Database (#ApeFD)!
620 #hominin faces, with #morphometric data + "vibe check" (#threat, #sociability, #trustworthiness... you name it).

Researchers can use this #open dataset to explore questions on #ocular #morphology, social perception, facial morphology, and even applications in cross-disciplinary fields such as #primatology, #cultural #anthropology, and media studies. Go wild, use it in your research, and e-mail us if you have any questions! :D

Morphological disparity of early #ammonoids: A geometric #morphometric approach to investigate conch geometry of Early–Middle Devonian ammonoids of the Moroccan Anti-Atlas by analysing the shape of their whorl profile:

Study highlights that the increase in #disparity began earlier than the increase in #diversity, but found no evidence for an early burst of #shape diversity (i.e., the rise does not exceed expectations given diversity).
