Fossil Amber with Insect included inside mm 17 x 10 x 4 Fossilized Resin from the Baltic Tertiary Cenozoic Oligocene Collecting Paleontology Plant Botany Museum.

Pleasant fossil sample of Baltic Amber from the lower Oligocene, representative collectible find of good quality, color and transparency, with clear details of the Insect -a Cockroach- which remained incorporated and perfectly preserved, with head, body, legs and antennas still visible.
No restoration at all. Only a piece, as in photo.
You can adder the magnifying glass-box (see Equipment Catalog).

Amber is fossilized resin. Resin is an organic mixture emitted by conifers, which can subsequently fossilize and solidify over time.
Resin means any mixture produced by a plant, of the fat-soluble type, consisting of volatile and non-volatile terpene compounds and/or phenolic compounds.
However, resins are a complex group of solid or occasionally liquid substances that tend to dry in air, insoluble in water but soluble in alcohol, ether and chloroform. Of very variable chemical composition, they are produced by plants both spontaneously and following stress (wound, pathogen attack); their role is probably to protect the plant from insects, fungi or other infections, or to close wounds.
They are also often confused in scientific literature with other very different substances: gums; mucilage; fatty oils; waxes; lactics. Resins are usually classified into the following 4 types: Consistent resins, Balms, Oleoresins, Gummoresins.
Currently, Fossil Amber or Baltic Amber is commonly collected in Poland, Lithuania, Latvia, Russia, Denmark, Germany and Sweden.
Fossil amber has also been found in sediments from the Carboniferous, a geological period before the appearance of angiosperms. Amber has the property of becoming electrified by rubbing. The greatest scientific importance of amber is due to the inclusions contained therein. In fact, the resin droplets, falling on insects and other small animals, could completely incomporate them, suffocating them and keeping them almost intact for millions of years. The hardening of the resin and its transformation into amber (Amberization) is a particular fossilization process which thus allows the anatomical characteristics of the preserved organisms to be studied in detail. Fossilizations in amber have allowed scholars to study the characteristics of insects and other small animals that lived in the geological past, providing very important data for understanding biological evolution, which otherwise would not have been available.
Amber is found, almost always in the form of nodules, included in sedimentary rocks.
The Amber Road, once also called the "Imperial Way", is a route of approximately 418 km that crosses the Baltic countries and Russia, traditional producers of fossil amber. Baltic amber is characterized by containing a large quantity of succinic acid, from which the mineralogical name of "succinite" derives. Although the major deposits are found in that area, the amber, over time, has been eroded by marine sediments, carried inland by storms and carried by streams and glaciers to secondary deposits found in the most of eastern and northern Europe, dating back to the late Eocene. Baltic Amber deposits are the largest and most extensive in the world and also the most studied since the 19th century. Baltic Amber appears to be 90% from a single paleobotanical source, but which source this is is not yet clear.
