palaeontologist have see beautifully preserved species pin in amber before — but this one is extraordinary . It have a parasitic white Anglo-Saxon Protestant that has become ensnared in a spider ’s web , with the owner bearing down on it for an attack . But just before the wanderer was about to have its repast , a drop of resin flowed down from above , freezing the moment in time .
Researchers go steady the shot to the Early Cretaceous between 97 to 110 million geezerhood ago in the Hukawng Valley of Myanmar — a time when dinosaurs would have most sure been in the neighbourhood . And in plus to the dramatic scene , the fossil also contain the body of a male wanderer in the same web — the first evidence of spider social behavior in the paleontological book .
Spider sociality still exists in some species , but it is very uncommon . Today , most spider live solitary spirit , often resorting to cannibalism — including males who often attack immature species in the same web .

But as for catching unsuspecting prey in a web , that looks like an evolutionary strategy that has survived the psychometric test of prison term . And in fact , spiders are an ancient invertebrate that first emerged about 200 million years ago . The oldest fossilize record of a wanderer dates back to 130 million years ago . This recent find is considered the first and only fossilized example of a spider onslaught on prey get in its web .
The specimen trapped in the rosin is an orb - weaver spider , a social coinage that has now been describe by the researchers in their newpaperwhich appear in Historical Biology . As for the wasp , it ’s closely related to a species that still survive today — one that is known to parasitize wanderer and insect egg .
It would seem that the wasp had it derive .
