Amber (Tukwila Fm./Renton Fm. [Boundary], Middle to Late Eocene)
3.0g of amber from the 9.2g lot depicted in the associated entry. This amber is middle to late Eocene in age (about 41.3-33.9 Ma), and comes from coal seams along the boundary of the upper Tukwila/lower Renton Formations. It is found in association with Pinus sp. and Metasequoia occidentalis remains, which were the most probable sources of the amber; association with Metasequoia sp. is even more prevalent among the amber from the Blakeburn Mine (i.e., amber from the Allenby Fm. near Coalmont), as Metasequoia imprints are especially abundant at that site.
