What are the parasites living in the feathers of dinosaurs? Source:

looks like an unknown parasite, stuck in amber

Today we know that many dinosaurs were covered with feathers, but it was not always so. From childhood we are told about the giant reptiles, and the film portrayed it as a scaly . Agree, after this, to imagine a formidable and frightening creature, covered with feathers from head to toe is not so simple. The reality is, as always, proved to be much more resourceful than we thought. Recently, researchers discovered amber in which was stuck a feather of a dinosaur, riddled with unknown insects. Scientists have estimated the age of the finds in 99 million years, and that means feathered monsters ate unknown to science parasite, whose appearance is strongly reminiscent of the lice.

To fall on our planet 65 million years ago, the true masters of this world were dinosaurs. But do not think that parasites avoid them — as shown by the results of a study published in the journal , the tiny parasites are apparently fed on the feathers of the dinosaurs.

First parasites that feed on feathers

The Tiny insects stuck in the resin of about 99 million years ago. Little pieces of Burmese amber, scientists have discovered a couple of feathers, and next to them 10 , similar to lice. On one of the feathers clearly visible bite marks. The researchers are convinced that the world's first discovery of the insects that fed on the feathers. At least of all registered cases. The discovery pushes back the origin of these insects is about 55 million years. However, previous studies have shown that in the past, many of the animals suffered from blood-sucking ticks.

Carefully read the discovery, the scientists came to the conclusion that insects belong to a previously unknown mind Mesophthirus engeli, are the nymphs — early stage of development . The bodies of the nymphs was tiny and wingless, and their length reached to 0.14–0.23 mm. in this case, the jaws of insects were observed at least four prongs. Scientists believe that the adults reach a length of about 0,5 mm. This puzzled the researchers, as previously discovered insects that era was much bigger. Perhaps for this reason, studying fossils, experts still have not found the ancient lice.

this is A Dracula — the blood-sucking mites that feasted on dinosaurs 99 million years ago. The researchers found it in the amber in 2017

However, the detection of even insects in ancient amber — a rarity. The team studied 1000 copies, containing preserved feathers of birds and dinosaurs, before to detect insects. Opening showed that the behavior of insects when feeding feathers arose, at least in the mid-Cretaceous period. Obviously, the parasites fed on the feathers of dinosaurs and feathers of primitive birds. As for the two feathers with a length of 12.7 mm and 13.6 mm, the researchers suggest that they probably originated from two species of dinosaurs, one of which was peneration — the bird-like theropod — though with confidence I can not talk about it.

Whatever it was, obtained the first evidence that feathered dinosaurs suffered from who chewed their feathers. Damage to feathers these tiny insects, have demonstrated Parallels with the damage that is applied to modern parasites, the study showed that these insects have evolved with feathers.
