Burmese amber is an invaluable source of scientific knowledge: the fossilized resin age 98,79 ± 0,62 million years frozen, a variety of fauna inhabiting our planet. Before scientists found mostly land animals: marine organisms had no chance to get into the hardened resin of coniferous trees. More surprising was the recent discovery in the piece of amber was cephalopod mollusk Ammonite.
The specimen, found in the North-East of Myanmar, gave scientists a collector who bought it in Shanghai for $ 750. The seller is assured that the resin envelops the land snail. However, the computer and x-ray scan revealed the presence of a complex of internal chambers, which do not have snails, but there have Ammonites. A small piece of amber (33 mm in length, 9.5 mm in width and 29mm in height with a mass of 6.08 g) was a real cemetery for 40 organisms. In addition to the Ammonite, it was concluded mites, flies, beetles, parasitic wasps, cockroaches, millipedes, isopods, and four shell Gastropoda.
The exact age of the fossils is not installed. On the basis of uranium-lead Dating of zircons from the adjacent rocks, we can conclude that amber got there 98.8 million years ago. According to scientists, in the moment of falling drops of resin on the shore were the remains of Ammonites and other animals made by the waves. Judging by the diameter of the shell (12 millimeters), the Ammonite died in a young age. Soft tissue not preserved; emptiness fills a large amount of sand. According to another version, the remains could be tossed by strong waves or even a tsunami so high that they are trapped in the resin of the riparian trees.
Although the sequence of events is not to recreate certainly, the discovery is important in any case for the science: it’s not every day you get the chance to explore the remains of marine life millions of years stored in amber captivity. Look at the bird-man in Burmese amber.
