About 66 million years ago, a massive asteroid collided with what is now known as Yucatan, plunging Earth into darkness. The impact transformed the tropical rainforests, giving birth to flowers.
Today, tropical rainforests are a hotspot for biodiversity and play an important role in global climate systems. A new study was published today in
La science It sheds light on the origins of modern rainforests and can help scientists understand how tropical forests will respond to the rapidly changing climate of the future.
The study, conducted by researchers at the Smithsonian Tropical Research Institute (STRI), showed that an asteroid collision that ended the dinosaur reign 66 million years ago also caused the extinction of 45 % of plants in what is now Colombia, giving way. at risk of extinction. The reign of flowering plants in modern tropical forests.
Life-size models of the Megalodon were built at the Smithsonian Museum of Natural History in Washington DC, and another at the Western Australian Museum Boola Bardip in Perth. Scientists wanted to determine how big the megalodons actually were.
However, the two beasts vary in size - the Smithsonian s is 15 metres while the Perth one is 14 metres.
Both of these are slightly smaller than the 18 metre depiction which scientists had believed megalodons grew to, which prompted a scientific investigation.
John Long, strategic professor in palaeontology at Flinders University, and Mikael Siversson, head of deparment, Earth and planetary sciences at Western Australian University, began analysing teeth of megalodons and discovered the species was actually bigger than previously thought.

UNCW marine mammal team plays role in identifying previously unknown whale species, 17 years later By WECT Staff | February 16, 2021 at 9:52 AM EST - Updated February 16 at 4:34 PM
CAROLINA BEACH, N.C. (WECT) - All the way back in 2003 two members of the UNCW Marine Mammal Stranding Team were called to Carolina Beach to check out a whale that had washed ashore - when they got there - they realized it was something they had never seen before.
Now, more than 17 years later, it turns out they were right.
