Dinosaur Feathers Discovered in Canadian Amber

Today a group of paleontologists announce the upshot of an extensive field of study of several well - keep up dinosaur feathers encased in amber . Their piece of work , which include sample distribution from many stage in the evolution of plumage , pad the determination of other scientist who ’ve suggested that dinosaurs ( wing and otherwise ) had multicolored and filmy feathers of the form you might see on birds today . The researcher also present evidence , based on the feather ’ pigmentation and structures , that today ’s birdie plume could have develop from dinosaur feathers .

We ’ve get under one’s skin a verandah of these challenging plumage preserved in amber .

In a profile of pencil lead investigator Ryan McKellar , The Atlantic ’s Hans Villarica writes :

These specimens stage clear-cut stages of feather organic evolution , from other - stage , unmarried filament protofeathers to much more complex structures associated with New diving birds . . . They ca n’t determine which feathers belonged to razz or dinosaurs yet , but they did observe filament structures that are similar to those seen in other non - avian dinosaur fossils .

Villarica also did io9 readers a favour and inquire McKellar whether this discovery could lead to a Jurassic Park scenario . McKellar said :

Put plainly , no . The specimens that we examined are highly pocket-size and would not be expected to incorporate any desoxyribonucleic acid material . To put this into context , the only genetical cloth that has been recovered from amber is from lumps of mummified insect brawn tissue paper in much youthful Dominican gold that are about 17 million years old and well after the age of dinosaurs .

So much for our dreaming of dino domination .

What you ’ll notice in the picture gallery below is that the researchers are emphasizing two basic piece of grounds : the similarity in coloration to today ’s bird feathers , and the similarity in sound structure or shape . Some of these feather strongly resemble those of diving water birds today ( and the researcher admit one example of a modern diving hiss feather so you’re able to liken them ) . Other structures , however , look nothing like feather of today . In a news report about McKellar ’s findings in Science , Sid Perkins writes :

In one case , the amber hold regularly spaced , empty filaments , each of which is about 16 micrometers in diam , about the size of the finest human hair . The filaments plain have no cell wall , so they ’re not works fibers or fungous thread , McKellar says . And they do n’t have features that depend like small-scale scale , as mammal hair does . “ We do n’t absolutely know what they are , but we ’re pretty certain what they ’re not , ” he notes . They could be protofeathers , McKellar aver .

legion individual filament in Late Cretaceous Canadian amber . These filaments are morphologically similar to the protofeathers that have been found as concretion fogey tie in with some dinosaur skeletons . paint distributions within these filaments set out from translucent ( unpigmented ) to close - black-market ( heavily pigmented ) .

Cross - section through a feather with basally - coiled barbules , companion by a microphysid industrial plant bug . The helical coiling observed within these barbules is most obvious in isolated barbules within the image , and is directly comparable to coils found in innovative bird feathers specialized for water uptake . The high telephone number of coils in the gold - entombed plume is revelatory of diving behavior , but similar social organisation are also used by some modernistic fowl to transport water to the nest .
