摘要

摘要我在波兰中部圣十字山脉的科瓦拉探索了 Dasbergina marburgensis → Dasbergina trigonica 系的化石记录。通过对平台 P1 元素的生物测量,我追溯了基因演化的轨迹。收集到的数据揭示了元素形态的逐渐变化,包括分支的发展、平台线的变化和基底腔的转变。一个有趣的方面是本体演化,我利用与动物寿命潜在天数相对应的节律增量对其进行了研究。值得注意的是,根据本体演化校准的分枝器官发生过程表明,这些锥齿动物经历了一个变态过程。此外,该研究还为法门纪晚期的年龄相关性提供了另一种方法,并为 Dasbergina 的进化史提供了新的视角。

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.
