Xixia Amber (Gaogou Formation, 100.5-85.8 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Amber Xixia Basin, Xixia County, Henan Province, China Gaogou Formation (100.5-85.8 Ma) Total Weight: 10.1 grams Overview: These pieces are all unwashed and still have an extremely fine layer of sediment; each has high clarity and rich color, many are naturally droplet-shaped, and individual measurements range from 1 to 8 millimeters in length. A few fragments of coal are also present within the lot. Prevalence, Inclusions, Botanical Source: Amber itself is quite common within the Xixia Basin, hosting China's largest amber reserves, but despite this is very rarely seen on the market. It has also been studied very little, mostly due to the fact that biological inclusions have not been known to occur in it. An araucarian source for this amber was determined based on chemical analysis. Geological Setting, Associated Fossils, Age: Amber occurs as lenses and droplets within the middle unit of the Gaogou Fm., in fine-grained sandstone which is non-marine in origin; the middle unit measures up to 440 meters thick, and also contains dinosaur egg and bone fossils, of at least 6 different genera: the presence of some of these species indicate an age of early Late Cretaceous. At other nearby amber sites (Wuliqiao Town) the presence of ostracod and bivalve fossils indicate a slightly younger age (middle to upper Late Cretaceous). Plant and pollen fossils are not known from the amber-bearing strata at Wuliqiao Town. Given the alluvial setting the amber is found in, and the absence of plant macrofossils in the matrix, I feel it may be possible that the amber was redeposited making it somewhat older than its host strata.

Hi, I am on the hunt for fake or synthetic amber with inclusions, and only fake or synthetic. The symposium that my society is hosting is having a silent auction and I would love to find someone to approach to make a donation request for a piece of fake amber with an inclusion. I have tried Google but all the results are for how to avoid fake amber, which is the opposite of what I am trying to do.

Amber with fluorensce & pine smell, but not floating
GEORGE-GR-68 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi members, glad to be here, I have a collection of fossils that mainly I want to ID and see also if they are real. My topic now is for amber beads but not sure if they are real or fake. I tried the following: UV light: Fluoresce green (light green) Hot needle test; It smells sweet pine ( after few seconds, not immediately). No definitely not plastic, in Greece there are pines I know the smell. Needle does not penetrate easily the beads. BUT I tried seawater, does not float, I tried also a lot of cooking salt (with iodine) and tap drinking water very warm, (not distilled water) in a stainless metal pan bowl (I had seen in a you tube video was not recommending metal bowl,I do not know why). I have put so much salt that it does not dissolve anymore. Result: They drop., Funny they seem to float a bit before they drop to the bottom, they do not drop down like rocks. Also if rubbed (for a minute) on a sweater (cotton or wool) the bead does not create static electricity, I do not feel my hair going up when I place the bead on my head. So two white flags and two red flags. Do I have topal? (I have no idea if topal behaves differently than amber) Do I have a plastic fake that smells like pine? Or I have real amber but I do something wrong? Any help? Thank you for any possible answer. Note: the same happens for various different beads ie: creamy yellow, light brown with spangles etc. -

I frequently purchase a large amount of amber from someone I know in Burma. Most of these pieces I only have some idea of what's in them until I get them in hand and am able to look at them myself under my microscope. I recently received another large shipment and it included this piece in it. As soon as I started looking at the inclusion I knew I had to make a post here for more opinions on the piece before I get my hopes up to much. However to me this 100 percent looks like a parasitic fungus that infected a Diptera. I'm not an expert by any means, but I've always had an interest in mycology, specifically parasitic fungi such as Cordyceps. Before I get my hopes up, what do you all think? It's definitely attached to the Diptera. I looked at it from every angle possible. I will be getting a macro photography set up but that won't be for a few more months so unfortunately this is the best photos I can get. All opinions are welcome, thanks!!

There are cross hatch patterns in the wood making it almost look woven. The rock imbedded in it or attached to it looks like amber. its bright yellow and dark when no light is behind it. The amber or agate looks like it has some of the same fiber pattern around the edges.

I was working on sorting through large group of amber I recently acquired, and this one struck me as interesting. I think I have seen this insect before, but having a hard time placing it. Raptorial legs, and an interesting snout/mouth piece. Any ideas?

Borneo Amber (Upper Nyalau Fm., 20.44-15.97 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Borneo Amber Merit Block Coal Deposits Kapit Division, Sarawak State, Malaysia Upper Nyalau Formation 20.44-15.97 Ma Weight: 351.5 grams Dimensions: 123 x 86 x 45 millimeters The specimen arrived freshly cut from what was a larger, football-sized specimen; with a minor amount of shaping/sanding, I then polished it as best I could. This material is very soft, so a glassy polish similar to that of harder ambers isn't possible. Borneo amber is essentially coeval in age with Sumatra amber, or at least its Formations (upper Gumai, Air Benakat, and lower Muara Enim), being Early to Middle Miocene in age. Like Sumatra amber, it is derived from a dipterocarp tree source, and is similar in color, clarity, and hardness. Both ambers also were deposited during periods of active volcanism, and indicators are easily seen in much material (esp. Sumatra amber): light-colored, opaque "swirls" are a common sight and are actually tiny suspended droplets of congealed resin, having formed in the presence of considerable heat. Direct and indirect effects of volcanism, such as reduced light due to ash clouds, caused great stress to the resin-producing trees, and enormous quantities of resin were produced: the largest single specimen of amber in the world was uncovered in Sarawak, and weighed 68 kilograms (~150 pounds).© Kaegen Lau

Is this genuine praying mantis amber?

Hey all, here's the latest 99-myo addition to my amber collection. Not sure I've seen too many other scorpions as large or well-posed as this beefy fellow; he's a little over an inch long not including the pincers/arms. It's a thin piece so the often foggy clarity of Burmese amber is luckily avoided here with little oxidation.

Hi everyone, I have a habit of framing my best fossils. However, I found quite a bit that are so tiny, I’m not exactly sure how to frame them. First off, the fossils are Amber. I found a bunch of tiny pieces while I was cleaning my room in the bottom of a bin. I actually didn’t know I had them. I confirmed it was Amber today by doing multiple tests. I’m trying to figure out how to frame these. Part of me wants to encase the amber in resin, then frame that. However, I’m not sure if this is advisable. Can someone give me an opinion or advice on how I should I attempt to frame these? Pictures are attached, Jared

Hi everyone, I was going through my rock collection, and I found a bunch of very tiny rocks at the bottom of the box. I immediately thought they looked like Amber or Copal. I took them out of the box, and I did the UV test. It turns out, I was right. It’s either Amber or Copal. I can tell by how it is glowing under the UV light. I pulled out my microscope and looked inside it, and did not see any insects. Oh well, I said. Then, I decided to do the hot needle test on one of the small pieces. During the test, the small piece broke, and it was kind of sticking to the needle a little bit. (The needle went in a little bit, making it stuck.) However, the needle did go in slightly before the small piece broke. Judging from the information I have, can anyone tell me if this is Amber or Copal? If you need more information or another test, I will do it. Pictures are attached, Jared

Feather and Skin in Burmite Amber
Rikache posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi there everyone! I’ve been wanting to expand my amber specimen collection for quite some time now and I recently came across a seller (which will remain unnamed per the forum rules) with some very interesting and unique listings posted on their page. I’ve included images of the specimens below; I was really hoping that y’all could give them a look and let me know what y’all think. The first specimen looks to have a lizard/snake skin inclusion. The second specimen contains small feather inclusions along with some even smaller organic matter. Both of these specimens are said to be Burmese amber (dated around 99 million years) mined in both Hkamti, Sagaing Division and Tanai, Kachin State, Myanmar. I’d love to hear your thoughts on whether these seem legit or not. And incase I do decide to acquire them, I’d greatly appreciate any tips on how to test them in person. Thank you all!

Taxonomy from Makarkin 2016. From Makarkin 2016, p, 127: "Derivation of name. From the Greek paradoxos [παράδοξος], paradoxical, strange, and Sisyra, a genus-group name of the family, referring to its mouthparts, which are unlike those of other sisyrids. Gender feminine. Diagnosis. May be easily distinguished from all other known genera of Sisyridae by a combination of the following character states: enormously long siphonate mouthparts likely lacking mandibles [mandibulate mouthparts in other sisyrids]; several setiferous calluses on head, pronotum present [absent in other sisyrids]; very long, slender hind legs (hind tibia and tarsus together more than 2/ 3 of forewing length) [hind tibia and tarsus together ca. 1/2 of forewing length or shorter in other sisyrids]; deeply forked CuP, AA1 in forewing [these shallowly forked or simple in other sisyrids]; complete inner gradate series of crossveins in hind wing [incomplete in other sisyrids]; RP with five branches in hind wing [two-three branches in other sisyrids]." Quote from a private message from Dr. V. Makarkin (October 2022): 'Dear Thomas, This specimen belongs certainly to Paradoxosisyrinae and is very similar to Paradoxosisyra groehni. But in Burmese amber, there are rather numerous other species of this subfamily, partly described in the attached paper. So, it may be identified today as 'Paradoxosisyrinae similar to Paradoxosisyra groehni' Identified by Dr. V. Makarkin, Paleontological Institute of Russian Academy of Sciences, Moscow.

Question regarding differentiating mosquitos, gnats, midges etc. in Burmese amber
Vytis posted a topic in Questions & Answers
I was wondering is there any way to determine the differences between these insects in Burmese amber? Is there anything different in comparison to their modern counterparts? I am looking into getting a mosquito, but midges look almost identical with the exception of the proboscis.- 3 replies
