The extinction of dinosaurs is considered one of the significant events of history as it brought a new era. Along with its Mammal Evolution. New species got introduced, and earth as a planet evolved to start a new phase of its living. But it is essential to note that Dino Extinction was not the end of events in that arena. The trove of fossils has shown that mammals have evolved after the Dinos got extinct due to crashing of an asteroid into the earth.
What Published Papers Have To Say About Trove Of Fossils Explaining Mammal Evolution
Mammal evolution has passed through a variety of stages since the extinction of dinos. This particular theory is explained through many published research papers. But first, let us know what “mammals” really are. Mammals are those animals who have glands that can produce milk. A published paper sheds light on the fact of how the ecosystem has recovered after the asteroid hit the earth. Ecosystem generally means the incorporation of the surrounding with different species. There were about 1000 vertebrates whose fossils included 16 mammal species. This trove of fossils also included different plant species
Continuous Records Of Mammal Evolution
This discovery of fossils led to the study of those things for which the archaeologists depended entirely on the teeth. The sites with the continuous records of fossils, a team of scientists were able to make out from the presence of volcanic ash that there was the presence of radioactive material. Moreover, the presence of fossils of ferns proved that there was an ecological disturbance because they only grow in disturbed areas.
Rebounding Of Plants And Animals
Many types of research showcased the foundation of plants and animals. Furthermore, researchers said that plants and animals rebounded. They discovered that palm forests replace ferns pretty soon. The variety in plants is what led to bringing distinction in mammals because now plant species were capable of supporting large mammal populations and fulfill their dietary needs. Also, there was diversification which brought evolution among mammals as the animal populations now were more sturdy and actively built than earlier. The mammal populations which grew after the extinction of dinosaurs were a hundred times big. This was after roughly seven lakh years of the extinction event.
Adding To Crucial Timeline
Earlier, there was a timeline lack because of not many things to prove the timeline and what happened in it. But the Colorado fossils not only help in giving information about the mammal evolution but also provided a proper timeline to the things. The fossils consisting of volcanic ash gave knowledge about the changes in biodiversity over time and also gave information about the temperature changes since ancient times. The site had layers of fossils putting light upon the years after extinction and was of paramount importance. The scientist was also able to make out what kind of dinosaurs used to move into the forests before they got extinct.
The study of these materials led to discoveries and filled up the blank places. The gain in the reviews made it possible to look forward to the future aspects and also helped in relating the processes of the present evolution to the past ones.
