A perfect presentation of a nicely prepared fossil Ammonite, the Golden Ratio in nature, on a base of the matrix in which it formed. An incidental series of unidentified straight-shelled ammonites are revealed in cross section as a result of the preparation of the matrix. A cut base provides a confident foundation for this classic representation of our natural history. Morocco. 6" x 3" x 4.5", 2.4 lbs.
