TEHRAN (Tasnim) - An array of perfectly preserved insects and even a spiders web, encased in 112-million-year-old amber, have been found in a quarry in the Amazon rainforest. Amber deposits come from two main sources: the above-ground parts of trees and the roots. Those from above the ground sometimes preserve the remains of insects and other life forms that got stuck in the resin that then turned to amber. This is the first time that [Mesozoic] amber with bio-inclusions of insects and spiders has been found in all of South America and they are certainly new species, Delclos said. We cannot have a Jurassic Park from Cretaceous amber, at least with current techniques, says Delclos.
