Sumatra Blue Amber (Sinamar Fm., ~30 Ma)

4.3g dark, transparent blue amber from West Sumatra. The inclusion is that of a slightly deteriorated specimen of Pseudomyrmex sp. of ant. There is very little documentation, written or photographic, of the flora and fauna inclusions in Indonesian amber, which makes me all the more excited to have discovered this piece!

Correction (May 6, 2024):

 

I would more accurately list the insects in this piece as being within the Pseudomyrmecini tribe; modern distribution of its members would possibly suggest a Tetraponera sp. rather than Pseudomeyrmex.

 

Also, after conferring with the seller of the amber itself, this material was mined from lignite deposits associated with the Gumai, Air Benakat, and Muara Enim Formations of the South Sumatra Basin: these range in age from 30-6.3 Ma.
