  • Conodonts - ScienceDirect
    Conodonts were discovered by Christian Pander in 1856 and are among the most useful fossils for dating strata over their ∼300-million-year evolutionary history (Corradini et al , 2024) The distribution of conodonts in space and time, now extensively researched, has proven that they are among the most important biostratigraphic tools for correlation of marine rocks from the upper Cambrian
