Question details
-Plot the data qiven in Q1
-the numbers indicate the sample number of the conodont data.
- the letters indicate the volcano ash beds some of which has radiometric data associate with.
-we want to know the absolute age of the strepthonathodus.
tem and stage boundaries Conodont Data 1. The list below shows the occurrences of key con- odont species in the Usolka River section. Using this data, plot the ranges of all conodont spe- cies on figure 2.3. Ranges of S. bellus, S. pawhus- kaensis, and S. brownvillensis have already been done by way of example.
