Could there be dinosaurs frozen in Antarctica?
Today, the continent of Antarctica holds the evidence of that ancient world, frozen beneath its ice and snow. As the climate changes again, melting Antarctic ice is allowing scientists to discover the remains of the past—including the fossils of those distinctive dinosaurs like Cryolophosaurus and Glacialisaurus.
Was Antarctica a jungle?
Today, the South Pole records average winter temperatures of 78 degrees Fahrenheit below zero. But roughly 90 million years ago, the fossils suggest, Antarctica was as warm as Italy and covered by a green expanse of rainforest.

What was found in Antarctica?
The scientists found the secret subterranean habitat tucked away beneath the Larsen Ice Shelf — a massive, floating sheet of ice attached to the eastern coast of the Antarctic peninsula that famously birthed the world's largest iceberg in 2021.
Why there is no trees in Antarctica?
There are no trees in Antarctica because it is both too cold and too dry for them to grow. Trees need a relatively deep layer of warm soil in which to plant their roots and Antarctica is much too cold to provide this.
Did they find a dragon in Canada?
Newly-identified pterosaur species had a wingspan of 10 metres. A huge, flying reptile that weighed as much as several adult humans combined and had the wingspan of a small plane soared over Alberta during the Age of Dinosaurs — and researchers have now identified it as a new species.

Have they ever found dinosaurs in ice?
Palaeontologists working on top a frozen Antarctic mountain have extracted a rock and ice fossil popsicle encasing the remains of a massive, previously unknown dinosaur. They used jackhammers, rock saws and chisels at a punishing 4200 metres to unearth the dinosaur, which represents a new genus and species.
Why are there few fossils in Antarctica?
It's because ninety-eight percent of the continent is covered in ice. Seriously, it's hard enough digging a camping latrine in icy ground. A fossil excavation is just well-nigh impossible.
What was the first fossils found in Antarctica?
The first fossil found was the Plesiosaurs, (marine reptile), it was found in Seymour Island in 1982.
Why are dinosaur fossils found in Antarctica?

The discovery of a single sauropod vertebra on ...
What continents were connected to the Earth by the Sauropods?
When the sauropods roamed the Earth, Antarctica was connected to South America and Australia, so sauropods could have simply walked from present-day continent to present-day continent, Paulina Carabajal said. The landmass of Antarctica itself was not as far south as it is today, so the continent would have been warmer, she said, although far from balmy.
Where are sauropods found?
The discovery of a single sauropod vertebra on James Ross Island in Antarctica reveals that these behemoths, which included Diplodocus, Brachiosaurus and Apatosaurus, lived on the continent in the upper Cretaceous Period about 100 million years ago. " Sauropods were found all around the world, except Antarctica, " said study researcher Ariana ...

What is the average annual temperature of the Antarctic Peninsula?
Unlike today’s temperatures in the Antarctic Peninsula, fossilised leaves found in sandstones and siltstones in the James Ross Basin of the Antarctic Peninsula region indicate that the mean annual temperatures for the area were 13 – 21°C ( 55 – 69°F). The fossil plants are indicative that the area had a warm climate without extended periods of winter temperatures below freezing, along with adequate moisture in the air for growth.
Why did the Antarctic forest go extinct?
During that time, volcanoes in Siberia released an enormous quantity of greenhouse gases into the atmosphere. The scientists found that the forests had a low diversity of plants each, and specific functions affected how the whole forest responded to environmental change. This is in contrast to modern forests today, which have wider plant diversity and therefore are more adaptable to change. Nonetheless, the Antarctic forest was quite resilient, with the plants able to survive through polar extremes of 24-hour light in summer and complete darkness in winter.
What did scientists find in Antarctica?
Meanwhile, researchers from UW-Milwaukee climbed the frozen slopes of the Transantarctic Mountains and found grey rocks containing fossils from Antarctica’s forested past. They found fossil fragments of 13 trees and discovered fossils of trees that are over 260 million years old, meaning that this particular forest was growing at the end of the Permian Period, before the first dinosaurs. At that time, Antarctica was still at the South Pole. The scientists were hoping to find fossils from the Permian Period, as this period ended 251 million years ago with a mass extinction caused by a sudden shift from icehouse to greenhouse conditions. During this time, more than 90 percent of species disappeared, including the polar forests.
What does the coarse sand that buries the trunks show?
However, the coarse sand that buries the trunks shows the power of floods in the area that eventually covered the whole plain in thick sediment. Fossilised leaves found in the area show that there was a large diversity of plants that once lived there.
How long ago did the plant life on the peninsula begin?
Over a three-year period, scientists determined the exact species of plants that existed on the peninsula 12 million years ago and found that the fossil record indicted a long, gradual process of glaciation over the peninsula.
How did the Permian period end?
The scientists were hoping to find fossils from the Permian Period, as this period ended 251 million years ago with a mass extinction caused by a sudden shift from icehouse to greenhouse conditions. During this time, more than 90 percent of species disappeared, including the polar forests.
How much does an elasmosaur weigh?
They estimate that the as-yet-unnamed elasmosaur weighed between 11.8 tons and 14.8 tons, with a head-to-tail length of nearly 40 feet. While some previously known Aristonectes have weighed about 11 tons or so, most other elasmosaurs only come in at around five tons. “That guy is big!”.

What Hampers Archeological Efforts in Antarctica?
- Besides frozen ground, archeologists and paleontologists find the same problems in Antarctica that other scientists do. The Antarctic Treaty System is a necessary peacekeeping operation, but it can present some sticky red tape. Threats of climate change give digging expeditions an “It’s now or never” feel to them. Scientists of all branches want to study Antarctica, but in a way that …
Current Exploration Efforts in The Antarctic
- Recent studies of the Antarctic fossil record have led scientists to conclude that a dearth of carbon dioxide can lead to global cooling. One such “icehouse state” occurred on Earth thirty-four million years ago. Before this event, Antarctica was a lush rainforest rather than the frozen waste it is now. This conclusion was drawn from the analyzation of microscopic fossils from bacterial …
The Likelihood of There Being More Fossils in Antarctica
- Antarctica is a very big continent. There probably are a myriad of fossils there. Excavating for them is the hard part. The British Antarctic Survey has collected some forty thousand specimens since their conception in the 1940s. Many of these fossils are the shells of invertebrates that have been instrumental in dating the surrounding rock. Most o...
Going to Antarctica?
- Would you like to go to Antarctica to look for fossils to bring home? Tough! Unless you’re part of an official scientific expedition, getting there will be hard enough. There are no commercial flights to the region, so tourists usually get there by cruise ship. The International Association of Antarctica Tour Operators wish for travel in Antarctica to be both safe and environmentally resp…
Conclusion
- It is quite surprising to find that a place like Antarctica was at one point rich in plant life and populated by dinosaurs. Finding fossilized remains of these former lifeforms is difficult to start with. Extracting them from frozen earth is even harder. Still, it is important to learn what life was before humanity.
