Tiger Mountain Amber (Upper-Tukwila/Lower-Renton Formations [Boundary], Middle to Late Eocene)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Incredible blue fluorescence in amber from Tiger Mountain, Washington State, U.S.A. No longwave UV light has been used here; these select pieces fluoresce in the same LED light conditions as Dominican blue amber, and with a strikingly similar coloration. Commercial quantities of blue amber have been officially described to be found in the Dominican Republic, Indonesia, and Mexico (Chiapas); to my knowledge, blue amber has never been described, much less documented, from North American deposits. Total weight is 0.4g, each piece measuring only a few millimeters in length. In the fluorescent video & image, specimens were submerged in water in a borosilicate glass petri dish; also, an additional video and image of the subjects when dry. *Please note there are several condensed air bubbles on surfaces of amber and glass.

Anchor Point Alaska Miocene plant materials
Sjfriend posted a topic in Partners in Paleontology - Member Contributions to Science
I have been in contact with the head of the University of Alaska Fairbanks and Museum for a couple years showing some of my better plant fossils from my area. Miocene age, Beluga Formation, This last week I had a Masters Degree student come and visit my collection and my local site. She is going to do her thesis on the local miocene flora. There are papers on plants presumed to be older and younger but none from this section of the formation. I donated approximately 100 lbs of specimens to the University of Alaska Fairbanks Museum of the North to be used by her then put in the Museum's collection. Based off the papers from other Alaska sites, it appears to be a mix of Salix, Betula, Alnus, Ficus, Populous, Metasequioa, Glyptostrobus, Taxodium and probably others. I know there are at least a few that are not described from this formation based off looking through the papers. Included in the specimens are leaves, twigs, branches, aments (cones and catkins) and other inflorescences. I know there are cones from 3 different families based on shapes and sizes. The student and her professor were quite thrilled and impressed by specimens they were able to take back. I will be donating a lot more from my previous trips after high grading them. And, now I am helping as an offical on-site field agent for this now official University project. So all my digging here for the next 3 years (expected length of project) will be for the university museum. Fine by me as plants are not my #1 fossil to collect.- 4 replies
