A study by the University of Granada (UGR) in Spain on Thursday presented new indications about the rapid recovery of life in the area where the asteroid that killed the dinosaurs fell, and caused the huge Chicxulub crater, on the Mexican Peninsula from Yucatan.

The research shows that life on the sea floor of the Chicxulub crater was recovered after the impact of the aforementioned asteroid, in a diverse and significant way, in just 700,000 years, a rapid period of time at a geological level.
The asteroid that hit Earth about 66 million years ago, represented one of the five great mass extinctions of the Phanerozoic, specifically the one related to the Cretaceous / Paleogene limit that caused the extinction of the dinosaurs on our planet.
According to an international study, in which the #UGR, life took ‘only’ 700,000 years to recover in the place where the asteroid that killed the dinosaurs hithttps://t.co/mulbYZ96Ok

The professor of the Department of Stratigraphy and Paleontology at the UGR, Francisco Javier Rodríguez-Tovar, one of the research participants, assures that in the range of a few dozen years, after the impact of the aforementioned asteroid, the community of organisms generating Traces had been recovered in full on the globe.
“However, this recovery was not sudden, but the product of different phases of diversification, stabilization and consolidation. According to the characteristics of the traces and the organisms that generated them, the importance of biological productivity is confirmed as the key factor in this rapid recovery, “explained Rodríguez-Tovar.
The study compares the referred mass extinction with those of other times, recognizing similar patterns between these events, but with an important difference regarding recovery time, suggesting a revealing new line of study in the evolution of life in the Earth and its recovery after such extreme natural events.
