Ethiopian Amber (Debre Libanos Sandstone; 23-16 Ma)
Barrelcactusaddict posted a gallery image in Members Gallery
From the album: Fossil Amber and Copal: Worldwide Localities
4.7g polished specimen of amber from one of several deposits near Alem Ketema, Amhara Region, Ethiopia; piece measures 35x24x17mm. There is a thin vein of transparent material, while the rest is heavily included with organic detritus; some small fragments of plant material are seen in the transparent portions (see associated photo). The green coloration is partly due to the amber's autofluorescence initiated by the LED light (transmitted) during photography; the clear portions of this specimen present a yellow-green base color in incandescent light, and emit a greenish fluorescence in sunlight© Kaegen Lau

4.7g polished specimen of amber from one of several deposits near Alem Ketema, Amhara Region, Ethiopia; piece measures 35x24x17mm. This view of the specimen displays organic detritus inclusions: in particular, a long fibrous subject (at center, beneath fluorescent layer) can be seen. The green coloration is partly due to the amber's autofluorescence initiated by the LED light (transmitted) during photography; the clear portions of this specimen present a yellow-green base color in incandescent light, and emit a greenish fluorescence in sunlight or LED light.

Sumatra Blue Amber (Sinamar Fm., ~30 Ma)
Barrelcactusaddict posted a gallery image in Members Gallery
From the album: Fossil Amber and Copal: Worldwide Localities
Palm-sized piece roughly 80g in weight. There is a very thin layer of coal on the top and bottom of the piece, making it a good example of a seam-type formation. It's blue coloration is purely surface fluorescence, initiated in this case by a 140 lumen LED light; this fluorescence (especially under a non-LW UV light) is caused by the presence of an exceptionally high concentration of various hydrocarbons contained within the amber.© Kaegen Lau

Palm-sized piece roughly 80g in weight, from the previous entry. Transmitted light through the deepest portion of the piece displays the amber's deep red coloration.© Kaegen Lau

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

From the album: Fossil Amber and Copal: Worldwide Localities
4.3g dark, transparent blue amber from West Sumatra. After grinding and polishing, I was surprised to discover that it contains 2 ants and 2 winged ants (possibly wasps); these were a little tricky to photograph, due to the amber's strong fluorescence under 140 lumen LED light, so these inclusions had to be backlit. I used a Canon EOS 500D, Canon 60mm f/2.8 Macro Lens, and combined 2x and 4x Hoya circular magnifier lenses (8x).© Kaegen Lau

4.3g dark, transparent blue amber from West Sumatra. Lateral view of the same Psudomyrmex inclusion in the previous entry. The antennae appear to have clubbed tips, but each is actually coated/overlain by a congealed drop of resin within the amber itself (this type of suspended resin formation is characteristic of and common in Indonesian amber).© Kaegen Lau

4.3g dark, transparent blue amber from West Sumatra. This displays 3 of the 4 inclusions contained in the piece itself, each one a Pseudomyrmex sp. (the winged ants may possibly be wasps, but it is unlikely).© Kaegen Lau

4.3g dark, transparent blue amber from West Sumatra. The inclusion is that of a well-preserved Pseudomyrmex sp. of ant. There is very little documentation, written or photographic, of the flora and fauna inclusions in Indonesian amber, unfortunately.© Kaegen Lau

Small (5-8g) partial nodules of raw blue amber from the east flank of the Bukit Barisan range of West Sumatra. These pieces are clear as glass, and fluoresce very nicely under a 140 lm LED light. *This Sumatra material (and Indonesian amber in general) is believed to have been produced by a parent tree belonging to the Dipterocarpaceae family; it's spectroscopic signature is also incredibly similar to Bitterfeld amber (also produced by a dipterocarp source tree). **This blue amber's particular locality is part of the Sinamar Fm., and the layers containing the resin are dated to be approximat© Kaegen Lau

Hello all, I need some help identifying this gastropod. It is from the Babcock Ranch northeast of Cape Coral and Ft. Myers. We collected these fine specimens from some of the "spoils" near the golf course. It appears to be a gastropod, but that is as far as I can go with the identification. Does anyone have any idea what the age and formation would be at this former quarry site? Most of my references would say "undifferentiated Pilo-Pleistocene deposits. Attached is a photo and a kmz link to the site. Thank you in advance! Greg Kruse Casper, WY Babcock

In the daylight, this is an articulated Exogyra shell from the Cretaceous New Egypt Formation as it runs through Mullica Hill, New Jersey. I brought it home because it had an interesting bit of vivianite replacement covering half the surface of one valve. When I brought it home, I noticed some white material inside the shell cavity. I figured it might be calcite, which sometimes fluoresces. So, I pulled out my UV lamp. To my shock, not only did the white material glow an interesting powder blue color, but the majority of the one valve glows an intense, bright red! Meanwhile, the other valve do -

I was playing around with the UV lamp in my lab, seeing what might unexpectedly glow this afternoon. This was a nice surprise. It's an internal mold of Bacculites sp. with sutures that fluoresce orange under 345nm UV light. Bright orange like this usually indicates calcite, a mineral that makes up fossil shells and some modern ones, too. Between the mud-filled chambers, the shell was preserved while the exterior of the cone wore away. The shell material was either calcite to begin with or, more likely, began as aragonite (same chemical compound as calcite, but different crystal structure and g© C. 2020 Heather J M Siple

a freind went for a fossil hunting in China's Beipiao, a well know lagerstatte of jehol biota ( early cretacous/late jurasic) . By chance he used a home UV light to check his pieces, just to find that one of them become fluorescent and revealing much more details. this should be a tyipcal Lycoptera davidi or sinensis

From the album: Fluorescent Petrified Wood
One of Delaware's many mysteries is the petrified wood found near Odessa and Smyrna. The general consensus is that is cypress wood of some kind and it was buried under Pleistocene sediments. However, the origin of the wood and the age have yet to be figured out. Some say Miocene. Others say as old as Cretaceous. There are no other co-occurring fossils in the deposit to give any clues. The photo on the right was taken using a 395 nm UV lamp. -
