Young Birds Living In The Same Period As Dinosaurs

The age of dinosaurs should be a time that everyone is very familiar with. Although this age is now very far away from us, it has to be said that, some fossils from the dinosaur period showed that the earth was also very prosperous at that time, especially that there are many large animals, like dinosaurs, which dominated the earth at that time. Dinosaurs were so big that almost no other animals on land could match them. Many of the fossils found today showed that animals at that time seemed to be extremely large. So were there any smaller animals at that time?

Scientists have been trying to find out the answer of this problem. It seems that most of the creatures were on land or in the sea at that time, were there any birds flying in the sky? We all know that there are many kinds of natural animals, and many kinds of birds flying in the sky particularly. At the age of dinosaurs, there were birds really, but they were different from the birds we have today.

Researchers have discovered an ancient bird at a Spanish fossil site that lived about 127 million years ago.The bird was a striking contrast to the dinosaurs of the dinosaur era, as they were not so large. On the contrary, it was quite small, only about 1/5 the weight of the golf ball, and about the size of the small grasshopper we see today.This kind of bird is unimaginable for the human being. The fossilized bird we found is about two inches long, which weighs is about 8.5 grams.

Until now it has been the smallest bird that ever found at the dinosaur period.The bird was very small, but almost all the bones in the fossil have been preserved completely fortunately. Because of the complete preservation of its skeleton, it is very helpful for people to study the community and characteristics of this kind of bird. But it is a pity that the bird is extinct, which means that there are no immediate relatives.

The newly discovered bird was not specifically identified as belonging to any particular species. It belonged to the Enantiornithes family, which was the most abundant birds at the cretaceous period. It was extremely widespread but was almost disappeared in the third cretaceous extinction event.

Although it is not clear that which species it belonged to until now, it didn’t dampen scientists' interest in these fossils, on the contrary, it attracts a great deal of interest in studying what makes the bird so special. Scientists imaged the samples of the birds by using the technology of synchrotron radiation, which is advanced and can help paleontologists learn more about this kind of birds.

By using this technology, scientists found that the bird was died from an accident shortly after hatching. Because the bird's breastbone was found in the fossil, and its breast looked soft, without the mature and hard solid bones, which means that at this time it was made of cartilage. Of course, this features are also very helpful for scientists to speculate on the life style of this kind of bird at that time.These features indicates that the birds which were hatched during the cretaceous period, should not have been able to fly.

In addition to this feature, scientists also analyzed its bone pattern and found that there are many differences from our current bird models. In other words, their evolution is rather different than we thought in fact. Perhaps what we thought is wrong, it should be diversified instead of simplexed.

As for the newly discovered bird, although it could not fly to find food at that time, it is likely that it did not rely directly on its parents to live and get food.Perhaps they were independent and seek food in other ways.Just like the chickens we see now, they can't fly in the sky but they are independent and can live a good life.

We can infer from the fossil that, although most of the earth's distribution is some of the larger organisms at the age of dinosaur,however, it cannot be ruled out that there were some smaller creatures at that period, which were just ignored by human being.
