Anagenetic evolution and peramorphosis of a latest Devonian conodont from Holy Cross Mountain (Poland)
Abstract. I explored the fossil record of the Dasbergina marburgensis → Dasbergina trigonica lineage in Kowala, situated in the Holy Cross Mountains of central Poland. Through biometrical measurements of the platform P1 element, I traced the trajectory of anagenetic evolution. The collected data reveal a gradual shift in the morphology of elements, encompassing the development of branches, a change in the platform line, and transformations of the basal cavity. An interesting aspect lies in the ontogeny evolution, which I studied using rhythmic increments corresponding to potential days of the animals lifespan. Notably, the organogenesis of branches, calibrated based on ontogeny, indicates that these conodonts underwent a process of peramorphosis. Furthermore, this study introduces an alternative approach for age correlation during the latest Famennian period and perspectives on the evolutionary history of Dasbergina.
期刊介绍:
The Journal of Micropalaeontology (JM) is an established international journal covering all aspects of microfossils and their application to both applied studies and basic research. In particular we welcome submissions relating to microfossils and their application to palaeoceanography, palaeoclimatology, palaeobiology, evolution, taxonomy, environmental change and molecular phylogeny.
