In this section, we have grouped together all the Orders belonging to the Phylum of Arthropods that have an extremely low fossilization potential in Amber and the special Fossil Behaviors.
In other words: RARE INCLUSIONS.
Mexican Amber is derived from the resin of an extinct Species of trees belonging to the Family Leguminosae, Subfamily Cesalpinoideae and Genus Hymenaea. The main Deposit area is located in the southern region of Mexico, Chiapas, on the border with Guatemala.
In Chiapas, this tree is better known under the name of guapinol.
Mexican amber Deposits are located approximately 70 km north of the city of San Cristóbal de las Casas, between the towns of Tapilula (west) and Yajalón (east), along the sides of the Rio Grande, Rio Blanco and Rio Santa Catarina and cover an area of approximately 600 km2.
Amber is found in geological Formations consisting mainly of limestones, siltstones and argillites with high levels of carbonate content, but also geological Formations of marls and sandstones, generally near (or inside) the lignite lenses.
The main Mines are located mainly between 500 and 1000 m above sea level.
The geological age of these Amber Deposits goes back to the period between the Upper Oligocene (about 26 million years ago) and the Lower Miocene (about 22 million years BURMESE AMBER (BURMITE)
BURMESE AMBER (BURMITE)
Burmese Amber, also called Burmite (Amber from Myanmar) originates from the resin of a tree similar to the extinct Agathis.
Burmese Amber Deposits are located in the Hukawng Valley of Myanmar (in the northern part of Myanmar: Kachin Region).
Deposits of Amber from Myanmar are also found in the central part of this country (Magway Region – Gangaw District).
The geological age of both Amber Deposits goes back to the Period between the Upper-Lower Cretaceous (about 108 million years ago) and the Lower-Upper Cretaceous (about 95 million years ago).
Its geological age is of great interest. In fact, in addition to its value on the Collectors’ market, the amber of Myanmar is of great scientific importance because the study of its fossil inclusions allows obtaining information on the paleo-ecosystem of 110-95 million years ago.
