Pushing Back Amber Production

  pages={51 - 52}
Amber from 320 million years ago is surprisingly similar to that formed much later by resins from flowering plants. Amber, the fossilized remains of tree resin, was precious and warm to Neolithic peoples, who gathered it from the cold shores of the Baltic Sea at least 13,000 years ago. Deposits of amber from Lebanon preserved insects trapped in it nearly 130 million years ago. On page 132 of this issue, Bray and Anderson (1) report that plants have been making amber for at least 320 million… 
Amber Sources and Trade in the Prehistory of the Iberian Peninsula
The use of amber is documented in the Iberian peninsula since the Palaeolithic. The procurement and trade of this fossil resin has often been considered in discussions of long-distance trade and the
IR and py/GC/MS examination of amber relics excavated from 6th century royal tomb in Korean Peninsula.
Ctenolepisma longicaudata (Escherich, 1905): a common, but previously unregistered, species of silverfish in the Faroe Islands
Although previously unregistered in the Faroes, a citizen-science approach using social media showed that C. longicaudata is widespread and common, and can be more of a problem in archives, museums and alike.
Changes in IR Spectra of Ambers with Accelerated Aging
Amber has been used as gemstones and artifacts from the period of the Three Kingdoms or earlier, which are discovered in the process of excavation now. It is, however, very difficult to discuss the
Analysis of changes in composition of amber with ageing using pyrolysis/GC/MS
Abstract: Ambers have been used mostly as beads, jewelry and ornaments from ancient times and excavatedas a buried artifact. When excavated, they are severely weathered to be cracked, exfoliated and

Note on the discovery of Carboniferous amber associated with the seed fern Linopteris obliqua, Sydney Coalfield, Nova Scotia, Canada
We report on a discovery of amber from the Carboniferous sedimentary rocks of the Sydney Coalfield, Nova Scotia, Canada. The amber occurs in the form of droplets and as a linear feature and ranges in
Electrostatic Telegraphy17531816
A fter being rubbed against cotton or wool, amber acquires a static electric charge and attracts lightweight objects such as pieces of dried grass or dried leaves (Fig. 1). Amber has been prized for
Gems Through the Ages
Since thousands of years, gems were used as tools and amulets often associated with social status and money. At the beginning, gems were used in their rough form, or polished with curved surfaces or


Identification of Carboniferous (320 Million Years Old) Class Ic Amber
It is found that amber from the Carboniferous, dating to more than 300 million years ago, has a similar chemistry to that of amber from angiosperms that evolved about 150 million years later, demonstrating that preconifer gymnosperms evolved the biosynthetic mechanisms to produce complex polyterpenoid resins earlier than previously believed.
Examination of associations from some of the earliest terrestrial communities indicates that herbivory probably extends to the Early Devonian, in the form of spore feeding and piercing-and-sucking.
Carbon-13 nuclear magnetic resonance spectra have been examined under high resolution conditions for 31 samples of fossil resin that have been dated to the Cretaceous period. Samples from Alaska,
