Detecting speciation in the fossil record is a particularly challenging matter. Palaeontologists
are usually confronted with poor preservation and limited knowledge on the
palaeoenvironment. Even in the contrary case of adequate preservation and information, the
linkage of pattern to process is often obscured by insufficient temporal resolution.
Consequently, reliable documentations of speciation in fossils with discussions on
underlying mechanisms are rare. Here we present a well-resolved pattern of morphological …
