The big deal is that present day theories about how the Ice Age took place describe it as a slow process requiring thousands of years, meaning that when ice slowly formed over the land mass, it would have been impossible to conceal pine needles and blades of grass still thriving. What this core sample reveals is that the ice sheet must have formed very quickly. In other words, the grass and pine needles were abruptly covered with a massive sheet of ice that left the plants in a relatively preserved state that could be dug up and identified thousands of years later. In a similar way, scientists have also found frozen animal specimens that appear to have fresh flowers still in their stomachs, even while buried deep under the frozen ice.
What all this suggests is that geographic changes may happen far more rapidly than most scientists currently believe. Perhaps these Ice Ages are brought on by events that elapse in mere hours rather than thousands of years. If so, it would require rewriting the history of planet Earth and challenging the firmly held beliefs of geologists and Earth scientists alike.
