As the Earth’s surface transforms, entire ecosystems come and go. The anatomy of fossil plants growing in the Andean Altiplano region 10 million years ago calls current paleoclimate models into question, suggesting that the area was more humid than models predict.
These maps dramatically illustrate how rising sea levels completely altered the shape of Panama’s coastline, creating islands and submerging large areas of land.
By integrating machine-learning technology with high-resolution imaging, scientists are improving the taxonomic resolution of fossil pollen identifications and greatly enhancing the use of pollen data in ecological and evolutionary research.
Coming from a humble family, Félix Rodríguez decided from a young age that he would focus on his education in order to secure a better future for himself and his family. At different points in his life he said yes to the opportunities that were presented to him, with a curious heart. This led him to learn from world-class experts, get training abroad and become a paleontologist at the Smithsonian (STRI) working in the Panama Paleontology Project. Listen to him describe his anecdotes and experiences as a paleontologist in the tropics.
The disproportionate extinction of South American mammals when the Americas collided is still evident today
The next time you eat seafood, think about the long-term effects. Will consistently eating the biggest fish or the biggest conch, mean that only the smaller individuals will have a chance to reproduce?
The new graphic novel tells the story of the Isthmus’ formation and evolution through the adventures of a young Panamanian girl.
About 66 million years ago, a huge asteroid crashed into what is now the Yucatan, plunging the Earth into darkness. The impact transformed tropical rainforests, giving rise to the reign of flowers.
Large marine animals generally have unique functions for the ecosystem. They are also more susceptible to extinction when their habitats are altered. Around 3 million years ago, at least one third of the marine megafauna became extinct, possibly due to sea level fluctuations and the contraction of coastal habitats. This also led to a loss of some of their ecological functions. In the current era, many large marine animals are deemed at risk of extinction. What will be the consequences of this potential loss?
Sharks’ bodies are covered with tiny, tooth-like scales called denticles. Shed denticles settle to the ocean floor, where they remain in sediments for years and can be used to understand which sharks lived on a reef in the past.
