#Ammonites' fate sealed by meteor strike that wiped out #dinosaurs
https://phys.org/news/2024-06-ammonites-fate-meteor-dinosaurs.htmlLate #Cretaceous #ammonoids show that drivers of diversification are regionally heterogeneous https://www.nature.com/articles/s41467-024-49462-z
"their fate was not set in stone. Instead, the final chapter in ammonite evolutionary history is more complex"

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:
http://dx.doi.org/10.4202/app.01033.2022Study 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).

Here we analyze the impact of #facies, #region, #taxonomy, and #collection style over #size #distributions using diameter as a proxy of Late #Devonian #ammonoids in their entirety using non-metric #multidimensional #scaling and #PERMANOVA based on #Kolmogorov distance.
