Glossopteris also produced very characteristic striated bisaccate pollen. My post doc involved studying such pollen and using it to correlate the strata.
Scott's Bag of Rocks - The Evidence That Proved Earth's Continents Move
​In March 1912, five men were dragging themselves across the white ice desert of Antarctica, fighting against death. Their bodies were frozen solid. Their food was finished. The storms showed no sign of stopping. The only thing they needed to do to save their lives was to travel as light as possible. However, there was a heavy load they decided not to leave behind. It was not gold or diamonds. It was a bag of rocks weighing about 16 kilograms.
​Even today, that decision is considered with respect as one of the most amazing sacrifices in the history of world science. This is because, at an extremely critical moment, they valued science more than saving their own lives.
​In 1911, the Terra Nova expedition team, led by British naval officer Captain Robert Falcon Scott, and another team led by Norwegian explorer Roald Amundsen set off for Antarctica. They went to claim the historic honor of being the first to step on the South Pole. But Captain Scott's British team did not go just to cross the Pole. They had another serious purpose. It was a massive scientific project to conduct extensive research on the geology, biology, meteorology, and glaciology of Antarctica.
​However, the historic honor of stepping on the South Pole first went to the Norwegian team led by Roald Amundsen. They successfully reached the South Pole on December 14, 1911.
​Captain Scott and his group reached the South Pole 34 days after Amundsen, which was on January 17, 1912. Even so, Scott’s team left a more valuable legacy to the world through their scientific discoveries than Roald Amundsen, the Norwegian who arrived first.
​Scott's team included geologists, biologists, meteorologists, and even glaciologists. During the journey, they continuously measured and recorded data on temperature, atmospheric pressure, wind patterns, and snow structure. They also collected a large number of biological samples, including penguin eggs and marine life from Antarctica.
​But unfortunately, they did not get the chance to return. On the way back from the South Pole, all five members of the group—Scott, Edward Wilson, Henry Bowers, Lawrence Oates, and Edgar Evans—died due to extreme cold, hunger, and blizzards.
​On a snowy day in November 1912, another search team traveling through the silent white desert of Antarctica found the frozen bodies of Captain Robert Falcon Scott and his group inside their small tent. They had disappeared months before. When they were found months later, there was only a heavy bag of rocks near the bodies.
​Those were not ordinary rocks. They contained a collection of fossils of an ancient plant called Glossopteris. These unique samples were collected by Dr. Edward Wilson, a geologist and doctor in Scott's team, from rock walls near the Beardmore Glacier in Antarctica. Later tests revealed that these rocks contained leaf fossils of Glossopteris, an ancient, extinct fern-like plant.
​Even while standing at death's door, these explorers, who had abandoned every non-essential item to make the journey easier and reduce weight, had carried this collection of rocks and fossils weighing 16 kilograms on their sledge until the very last moment.
​Why did a group of starving men, with no strength even to take a step, carry such a heavy bag of rocks even in the face of death? Why didn't they abandon it until the very end?
​Historical Note (February 7, 1912 - From Scott's Diary)
"I decided to camp and spend the rest of the day on geological research... We were able to find coal layers and clear plant fossils between the 'Beacon Sandstone' rock walls."
​This ancient plant named Glossopteris, which lived over 250 million years ago, had been found not only in Antarctica but also in India, Africa, Australia, and South America. Even though these countries are separated by oceans today, it was a big question for scientists how the same plant spread across countries so far apart.
​In 1885, Austrian geologist Eduard Suess proposed an idea that South America, India, and Australia were joined together in the past as a supercontinent called "Gondwana." When this concept was presented, Antarctica was not included because nothing was known about Antarctica's geology at that time.
​In 1912, the same year Scott died, Alfred Wegener from Germany introduced the theory of Continental Drift to the world. Wegener pointed out that continents are moving away from each other and that the continents that are separate today were once parts of a huge landmass named Gondwana. But strong evidence was needed to prove this.
​The Glossopteris fossils brought by Scott's team became the strongest physical evidence that Antarctica was also part of this Gondwana continent and that these continents were joined together in the past. These fossils showed that Antarctica, where the entire land is covered by thick ice layers today and no plant can survive, was once a land covered with forests with a mild climate. Along with that, the idea that the continents of the Southern Hemisphere were connected was strengthened.
​This is because the seeds of the Glossopteris plant are very heavy. Therefore, they cannot be carried thousands of kilometers away by wind or sea water. So, finding this plant on many continents is concrete evidence for the argument that those continents were joined together in the past.
​Later, in the 1960s, with the discovery of Seafloor Spreading, the Continental Drift theory moved one step forward and gained full acceptance in the scientific world as Plate Tectonics. It was confirmed that Earth's crust consists of several plates, and these plates are constantly moving, colliding, and drifting apart due to heat waves inside the Earth.
​Unfortunately, Alfred Wegener did not know about these fossils found by Scott from Antarctica when he wrote his world-famous book on Continental Drift, "The Origin of Continents and Oceans." (This book contained the evidence and theory that all of Earth's continents existed as one single supercontinent called "Pangea" in the past, and later they separated from each other and drifted to their current locations.)
​Although Captain Scott and his team lost the race to conquer the South Pole and died tragically, that 16-kilogram bag of rocks they did not abandon paved the way to rewrite Earth's geological history.
​Today, research in Antarctica continues to expand our knowledge about the history of the Gondwana supercontinent, how continents broke apart, Earth's climate change, and plate movements. But on the first pages of that massive scientific journey, the story of a bag of rocks that was not abandoned even near death cannot be forgotten. The sacrifice of those brave explorers, who fought for science and knowledge until their last breath even while fighting between life and death under extremely difficult conditions, remains an immortal memory written in golden letters in scientific history.
​Science is not something that is always born in a laboratory. Sometimes it can be born within a few ordinary rocks held in the hands of men fighting for life in the middle of a blizzard. If Scott's team had abandoned that bag of rocks that day, no one knows if they might have lived for a few more days. But the lesson the rocks they brought taught the world is clear today. Even though a human life ends, the journey in search of truth never ends.
