Ammonoids are a group of extinct marine mollusk animals that are now an iconic fossil group often collected by amateurs. Over 350 million years of evolution, ammonoids developed increasingly elaborate shells with fractal-like geometry. For nearly 200 years, scientists have debated the reason why these animals show a trend of increasing complexity in their shell structures.

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).
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.
Ammonites are an extinct and charismatic lineage that persisted for over 300 million years. They were used, with other fossils, to corroborate the principle of faunal succession and launch the field of biostratigraphy. Despite intense research, many important questions remain unanswered. Furthermore, outdated hypotheses persist. Many new findings include a better understanding of their appearance in life, their locomotion, and their role in long gone ecosystems. And, of course, there are still c
