In Canada, researchers came across another amazing find. The jaw of the Hadrosaurus - a duck-billed dinosaurs that lived in the late Cretaceous period.
This is reported by the publication Science.
"It's not every day that scientists dig up a dinosaur jaw or excavate the remains of fossilized insects. Therefore, paleontologists could not believe their luck," - writes the edition.
It is noted that in 2010, scientists found the jaw of a duck-billed hadrosaur aged 75 million years in the Provincial Park of dinosaurs in the Province of Alberta in Canada. It had a seven-centimeter-long blob of amber that contained traces of wood and aphids (which suck plant sap).
The paleontologists believe that after the Prosaurolophus hadrosaur died—and the flesh had decayed off its jawbone—it washed into a river.
There, a blob of sticky resin from either a redwood or an araucarian conifer tree also fell. The blob, containing an unlucky aphid, washed up against the bone and was pressed against it by the flow of water, the scientists argue. It was then covered in sediment for tens of millions of years, during which time the resin hardened into amber.
The find is the first of its kind in North America and carries a load of mysteries about the dinosaur habitat.
"In particular, the traces of plants and insects inside confirm the hypothesis of many paleontologists: that some hadrosaurs, including the nine-meter-long Prosaurolophus, fed on coniferous trees near coastal floodplains," the scientists add.
Earlier, "Apostrophe" reported that archaeologists from Germany discovered a 3000 year old bronze sword that is preserved in excellent condition.
