Baltic amber with insect in bulk
Baltic amber is fossilized resin of pine from Nordic region about 44 million years old. At that time there was a relatively mild climate and the pine forest stretched out far into the Nordic area with trees up to 40 meters high. By resin trapped insects are exceptionally well preserved and have learned a lot of science on evolution between these fossil specimens and our current bugs.
All in all pretty suggestive piece of earth history which inspired Steven Spielberg in the making of the film Jurassic Park. Do you know the professor still with his cane? It also includes a piece of amber with trapped insect. Unfortunately, it is not yet possible to obtain DNA from the trapped insects.
You get randomly selected pieces from a larger amount. All documents contain at least traces of insects, but generally the bugs have been completely preserved in amber. The amber has a size of approximately 10 t / m 25 mm, the insects have dimensions ranging from 1 to 3 mm.
