Mexican amber, also known as Chiapas Amber is amber found in Mexico, created during the late Oligocene and Early Miocene epochs of the Cenozoic Era in southwestern North America. As with other ambers, a wide variety of taxa have been found as inclusions including insects and other arthropods, as well as plant fragments and epiphyllous fungi.
Context
Mexican amber is mainly recovered from fossil bearing rocks in the Simojovel region of Chiapas, Mexico. It is one of the main minerals recovered in the state of Chiapas, much of which is 25 million years old, with quality comparable to that found in the Dominican Republic. Chiapan amber has a number of unique qualities, including much that is clear all the way through and some with fossilized insects and plants. Most Chiapan amber is worked into jewelry including pendants, rings and necklaces. Colors vary from white to yellow/orange to a deep red, but there are also green and pink tones as well. Since pre-Hispanic times, native peoples have believed amber to have healing and protective qualities. The largest amber mine is in Simojovel, a small village 130 km from Tuxtla Gutiérrez, which produces 95% of Chiapas' amber. Other mines are found in Huitiupán, Totolapa, El Bosque, Pueblo Nuevo Solistahuacán, Pantelhó and San Andrés Duraznal. According to the Museum of Amber in San Cristóbal, almost 300 kg of amber is extracted per month from the state. Prices vary depending on quality and color. The amber dates from between 22.5 million years old, for the youngest sediments of the Balumtun Sandstone and 26 million years old for the oldest La Quinta Formation.
Origin
The amber was produced by either the two extinct leguminous trees Hymenaea mexicana or Hymenaea allendis, both of which were initially described from fossil flowers included in Mexican amber.
Fossil inclusions
The Tityus apozonalli scorpion holotype fossil is composed of a very complete adult male recovered from the Guadalupe Victoria site. The amber dates from between 23 million years old at the oldest and 15 million years at the youngest. The Guadalupe Victoria site is an outcrop of amber bearing strata belonging to the Mazantic Shale and Balumtum Sandstone. The deposits preserve a transitional river or stream environments near the coast and preserves fossils of a mangrove forest ecosystem. Asteromitesmexicanus is an epiphyllous coelomycetes fungus species recovered on a petal.
