Description: Montana Reference Fossil * Compare the upper fragment portion with the W.I.S. bone fragment sample. Both samples are the same size, complex shape, and exhibit the "exact" fracture pattern angles. Note: 25+ WIS fragments have been studied that exhibit the same complex repeating size and shape, suggesting a bone-fossil is the only plausible explanation.
