Feathered dinosaurs were eaten by lice-like insects, study says

Paleontologists have found that feathered dinosaurs had been eaten alive by lice-like bugs, based on a brand new research.

The researchers checked out items of amber, roughly 99 million years outdated, and located that the feathers are coated with lice-like bugs that belonged to a newly found species, referred to as Mesophthirus engeli. Of the 1,000 specimens that had been examined, 10 of them had the bugs and, in a single case, a feather confirmed indicators of being eaten.

“This new insect clade reveals a sequence of ectoparasitic morphological characters resembling tiny wingless physique, head with robust chewing mouthparts, strong and quick antennae having lengthy setae, legs with just one single tarsal claw related to two further lengthy setae, and so forth,” the researchers wrote within the research’s summary.

“Most importantly, these bugs are preserved with partially broken dinosaur feathers, the harm of which was in all probability made by these bugs’ integument-feeding behaviors,” they continued. “This discovering demonstrates that feather-feeding behaviors of bugs originated at the very least in mid-Cretaceous, accompanying the radiation of feathered dinosaurs together with early birds.”

One of many research’s co-authors, Chungkun Shih, a visiting professor at Capital Regular College in China, advised The Guardian “[t]his is the earliest recorded, or formally documented, [instance of] lice or louse-like bugs feeding on feathers.”

The specimens of M. engeli had been nymphs and would have doubtless reached roughly 0.5 millimeters in size when totally grown, the researchers discovered.

Shih mentioned the minuscule measurement of the bugs shocked him.

“Primarily based on our research of fossil fleas, we thought that if we had been in search of lice, the scale could also be greater than at present’s lice, however [they] turned out to be very small,” he advised The Guardian. “That may clarify why on compression fossils [in rocks] we can not discover any lice.”

The feathers are doubtless from two sorts of dinosaur, together with a pennaraptoran, The Guardian reported.
