During the 4.5 billion-year adventure of the planet we live on, there have been 5 great kidollarsonic extinctions. This is one of the great extinctions and the last.65 million years ago was the K-T extinction that took place and brought the end of the osaurs.A larger meteor on Everest
In this extinction that occurred after collided with our planet, the vast majority of living species disappeared.
Osaurs are the last until this meteor strike. for 175 million years was the ruler of the planet. Evolved into hundreds of different species, the osaurs lived in a lush world in abundance, but an unexpected meteor had wiped out everything about the osaurs from the map.what is left of the osaurs is the birds. Birds are the only living thing that has the remains of the osaurs and still bears traces of them today. But of course, in the evolutionary process between osaurs and birds, there are also intermediate forms that can neither be called birds nor osaurs.
A fossil of a ‘half bird, half-asaurus’ creature that lived 120 million years ago has been discovered in China:
Many studies have found fossils that allow us to better understand the connection between osaurs and birds. The last example came from northeastern China.Head that looks just like Tyrannosaurus rex but a fossil whose body resembles today’s sparrows or hummingbirds has been discovered.
The size and yellow of the fossil found is astonishing. This tiny creature’s head resembling a Tyrannosaurus rex only 2 cm in size. Paleontologists examining the fossil state that the tiny creature belongs to an early bird group known as enantiornithines, which went extinct millions of years ago. Although this group of birds disappeared during the Great Extinction, it is known that some of its features are seen in many birds today.in the evolutionary process leading to modern birds is known to have an important place.
