Astronium truncatum
Oligocene
Ruby River Formation
Ruby River Basin, Madison Co.
Montana, USA.

The main flower is preserved in crisp relief, showing a clearly defined central floral structure with radiating petal impressions, while subtle venation and organic texture remain visible within the surrounding matrix. The secondary flower, positioned nearby on the same slab, provides exceptional compositional balance and enhances the scientific and visual appeal of the specimen.
Beautiful 32mm flower on 110mm slab with couterpart flower attached to the slab as well.
