Fossilized snapshot of mass death found on North Dakota ranch

In other words, in a cow pasture near Bowman in southwestern North Dakota, DePalma had found a geological snapshot of the day the dinosaurs died. An interesting site
Rudy Pascucci was along with DePalma when he made the fateful decision to visit the cattle ranch near Bowman instead of driving to an established fossil bed in Harding County, South Dakota. The fossil site near Bowman, which DePalma calls Tanis, a reference to a lost Egyptian city, demonstrates how extinctions could occur rapidly even thousands of miles from the asteroid crash site.
