Wellmann Method of Strain Analysis • uses bilaterally symmetric objects, such as shell fossils to determine a strain ellipse for a sample
Wellman’s s Method Cont… 1. number each fossil 2. draw arbitrary reference line 3. draw reference line/pts. on tracing paper 4. draw hinge and median lines at each reference point for each fossil 5. make a point for line intersections 6. draw best fit ellipse through points
