Dominican Amber (La Toca Fm., 20.43-13.65 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
A rare and very unusual specimen, weighing 10.0g and measuring (mm) 40x31x20. Most dominican amber is transparent to translucent, yet this specimen is more akin in appearance to the "butterscotch" variety of Baltic amber; I have not determined if the turbidity is due to microscopic air bubbles, or organic inclusions, though it is most likely the former. This type of dominican amber is sometimes seen as a thin layer/flow overlying transparent material, but this specimen is mostly whole, and it's unaltered exterior does not indicate to its having overlain any previous flows. I uncovered this piece while cleaning a 2kg lot of mine-direct material.© Kaegen Lau

Coleoptera with exuded gas bubbles; these are likely methane, and could be the by-product of methanogenic bacteria inside a xylophagous (wood-eating) species. Some adult members of the Cetoniinae subfamily (family: Scarabaeidae) are xylophagous and known to produce methane; while this is known from Recent species, it's possible such characteristics could be found in extinct members of the Scarabaeidae or Scarabaeoidea (superfamily). This inclusion is contained in the same specimen depicting pholadid crypts. Provenance of specimen is Tanai Township, Myitkyina District, Myanmar.

Polished specimen containing sediment/calcite-filled domichnia (burrows/crypts) formed by mollusks of the family Pholadidae (likely subfam. Martesiinae): these features were formed while the resin was in a marine environment and after it had sufficiently hardened, all preceding its burial and subsequent diagenesis.

From the album: Robs Fossil Collection
Hand polished piece of Madagascan amber Copal. This Copal has not had a definite date put upon it yet, but it is thought to be a similar age to the Columbian Copal, so that would place it in the Pleistocene age until more accurate dating. It is thought that similar environments around the world at that time created amber copal that has formed almost identical to each other and the insects are similar too, if not the same, just like today. Copal Size: 5.5cm -
Hi all! First post here, spent some time reading the tips and rules so I hope I got everything right, but if I didn't please let me know. I just got this specimen from a seller in Indonesia, who claimed it was Sumatran blue amber. The 'blue' part is skeptical, though it does seem to fluoresce a bit in direct sunlight. I've run all the amber tests I am capable of doing (the rub-and-smell test, the static test, scratch test, black light test, acetone test) and for all intents and purposes it does seem to be amber, but I noticed last night when I was playing around with the black light, the amber retains a very faint residual glow after the black light is turned off, and the glow fades rapidly. I can't seem to find any resources online about whether this is normal or not, so I figured I should ask here. The pictures below are three of the amber piece in standard room lighting, one of the residual glow, and one of the UV fluorescence (I removed it from the scale paper as the white was washing out the blue fluorescence on-camera).

Taxonomy according to GBIF: Smarididae are large predatory mites with long oval bodies that are clearly pointed at the front. The (recent) predatory mites are usually red in color and densely hairy with slender, sometimes very long legs. They have either one or two pairs of eyes. Identified by Dr. J. Dunlop (Museum für Naturkunde, Leibniz Institute for Evolution and Biodiversity Science in Berlin, Germany) and Dr. J. Makol (Department of Invertebrate Systematics and Ecology, Wrocław University of Environmental and Life Sciences, Poland) as Smarididae indet. References: Dunlop, Jason A., Frahnert, Konrad, and Makol, Joanna (2018). A giant mite in Cretaceous Burmese amber. Foss. Rec., 21, 285–290. Wohltmann, Andreas (2010).

Cretaceous Burmite Feathers appear to show Color
Biotalker posted a topic in General Fossil Discussion
This piece of amber containing an inclusion of feathers was extensively cracked but had an interesting feature: it appears to show a silver reflective color in a distinct pattern. These tiny feathers have an apparent reflective substance on certain parts of primarily two adjacent feathers that show this pattern. In some angles a silver color is visible. How common is this? Do you think this is an actual color on whatever bird/non-avian dino it was a part of?

Cretaceous Burmite Dipteran stuck in amber just after Eclosion
Biotalker posted a topic in General Fossil Discussion
This dipteran became stuck in amber approximately 100mya just after eclosing (coming out from its pupal case as a new adult). The shape of the wing indicates it was in the process of unfurling and therefore never took flight..thumb.jpg.e66245b14bc9201eb2b7ae7611f8c3c7.jpg)

Burmite Cretaceous Soft Tissue: Remarkable preservation of Dipteran Indirect Flight Muscles
Biotalker posted a topic in General Fossil Discussion
Here is a Cretaceous Burmite Midge that appears to show preservation of the indirect flight muscles in one hemithorax. Indirect flight muscles distort the thorax cuticle from the inside to indirectly move the insect’s wings and power flight. While this level of microscopy cannot prove the tissue is muscle, it seems likely that the two sets of power muscles for flight are visible in this fossil: six dorsolongitudinal muscles (DLM) and six dorsoventral muscles (DVM). There are smaller muscles that play a role in guidance and directional movement that may be present but cannot be unambiguously determined without better tools. This midge is on the surface of the amber on its mid-sagittal plane with half of the insect gone..thumb.jpg.25c917daa2096aaeb8ab619338c9e8f8.jpg)

Sumatra Blue Amber (Sinamar Fm., ~30 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
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

Sumatra Blue Amber (Sinamar Fm., ~30 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
4.3g dark, transparent blue amber from West Sumatra. This inclusion is most likely a winged ant of the Pseudomyrmex genus, although it may possibly be a wasp. A positive identification of both winged subjects is challenging, due to their deteriorated state and their position within the piece.© Kaegen Lau

Sumatra Blue Amber (Sinamar Fm., ~30 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
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

1.2 gram amber from Tiger Mountain, King County, WA. Smaller inclusions consist mostly of slightly darker, congealed resin positioned along natural flow lines; this feature is by far most commonly seen among the Indonesian ambers. The few large, dark masses are botanical debris. Image taken under approx. 10x magnification with a Belomo Triplet loupe. This amber is middle to late Eocene in age (about 41.3-33.9 Ma), and comes from coal seams along the boundary between the upper Tukwila/lower Renton Formations.© Kaegen Lau

Two exceptionally fluorescent pieces of amber from Tiger Mountain, King County, WA. These were illuminated with a 140 lumen LED penlight, not a long wave UV light; this is a surprising feature for amber of this locality, as blue amber is only well-documented to come from the Dominican Republic, Indonesia, and Chiapas. 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.© Kaegen Lau
