    “Sakhalin Amber” Sakhalin Island, Russia Starodubskoye, Nayba River Estuary Naibuchi Fm. (Autochthonous) Middle Eocene (~47.8-38 Ma) Specimen C: 0.35g / 14x8x6mm Lighting: 140lm LED Entry eight of ten, detailing various rare ambers from European, Asian, and North American localities. The island Sakhalin is located in the Far East region of Russia, just north of the island of Hokkaido, Japan. Amber is usually found washed onto the shoreline, near the village of Starodubskoye; it is eroded from coal exposures of the Naibuchi Fm. and carried by the Nayba River, emptying in the Okhotsk Sea. The amber is considered autochthonous (found in original place of formation) or in the case of amber on the shoreline, parautochthonous (carried a relatively short distance from original deposit). Sakhalin amber is a variety of Rumanite which, as has been shown through recent analyses (E.C. Stout, et.al. 2000), is an amber identical or nearly identical to succinite (Baltic amber) that has undergone a high degree of polymerization; significant geological forces (heat, pressure) exerted on the resin during its burial, altered the resin itself and degraded/deformed any biological inclusions contained in the resin. As is often the case with Rumanite, particularly Sakhalin amber, the cavities inside trapped insects are found filled with resin, due to the intense forces the resin was subjected to. Rumanite also has a slightly higher melting point than Baltic amber, at 300-350˚C (as opposed to 250-300˚C). As of 2019, nearly 1,250 insect and arachnid inclusions have been discovered in Sakhalin amber, with aphids and chironomids (non-biting midges) comprising the majority of inclusions; strangely, beetle larvae are more common than their adult forms in this amber. Simetite, as a fresh resin, was believed to have low-viscosity as compared to other ambers; this property made it less likely for animals to become trapped. Interestingly, from a previously-studied collection of Rovno amber, it was found that 23% of all hemipteran inclusions were of the suborder Auchenorrhyncha, namely planthoppers (Infraorder: Fulgoromorpha, Superfamily: Fulgoroidea) and leafhoppers (Infraorder: Cicadomorpha, Superfamily: Membracoidea), with a 10% finding in Baltic amber, and less than 0.3% in Sakhalin amber: the low rates of occurrence in Sakhalin amber are possibly due to the small size of specimens in general, the low-viscosity nature of the resin, and/or a limited presence of planthoppers and leafhoppers in the ancient forest. Only a single leafhopper specimen has been described from Sakhalin amber.

    Siegburgite (Cottbus Fm., 25.5-23.5 Ma [min.])

    From the album: Fossil Amber and Copal: Worldwide Localities

    "Siegburgite" Goitzsche Opencast Mine Bitterfeld-Wolfen, Saxony-Anhalt State, Germany Bernsteinschluff Horizon Cottbus Fm. (25.5-23.5 Ma [min.]) Chemical Composition: C: 81.37%, H: 5.26%, O: 13.37%, Cinnamic Acid: 0.0073% Specimen A (Top Left): 0.4g / 14x12x6mm Specimen B (Top Right): 0.5g / 14x14x8mm Specimen C (Bottom Left): 0.3g / 14x12x4mm Specimen D (Bottom Right): 0.2g / 13x10x4mm *I did not take a photograph of these specimens under longwave UV, due to the fluorescent response of Siegburgite being so weak; they fluoresce a dull burgundy. Siegburgite is referred to as an "accessory resin", but is considered a true amber. It occurs alongside several other accessory resin species, as well as the more well-known Bitterfeld amber. Siegburgite is a fascinating amber, and is one of the few fossil resins classified as a Class III resin; it is essentially a natural polystyrene, found as concretions where it is a binding agent to fine sand and mica: the sand is often evenly distributed, and is variable in proportion to the resin, occasionally more than 60%. Siegburgite is highly flammable. Siegburgite was produced by a plant of the genus Liquidambar (Hamamelidaceae Family, also commonly known as the "witch-hazel" family): within the fresh resin, known as storax or copalm balsam, cinnamic acid and esters quickly decarboxylate (chemical reaction that removes a carboxyl group, and releases carbon dioxide), forming styrene; upon its burial, the newly-formed styrene underwent polymerization over tens of millions of years, as it became polystyrene. It is found in the lignite (German: "Braunkohle"), lignite-sand, and lignite-clay layers of the upper portion of the Cottbus Formation; Bitterfeld amber is also found within this Formation. The amber- and accessory resin-bearing layers are situated beneath the Bitterfeld Main Coal Seam, and above the Breitenfeld Seam. The Goitzsche Mine, from which Siegburgite and other fossil resins were obtained, opened in 1949 and closed in 1991.

  6. From the album: Fossil Amber and Copal: Worldwide Localities

    - Subjects: Three exceptional specimens of amber, recovered from exposures on Tiger Mountain, Washington State; this is the second of two videos detailing the specimens' natural fluorescent and phosphorescent responses: longwave UV light (Convoy S2 flashlight) was used in this entry. All were prepared by hand using a diamond needle file, 240 to 3,000 grit SiC sandpaper, and chromium oxide (ZAM compound) on a Selvyt microfiber cloth. - Amber's Source Formations and Age: The amber-bearing coal contained within the the Tiger Mountain, Tukwila, and Renton Formations spans a geologic timescale ranging from Middle to Late Eocene in age (~41.3-33.9 Ma). - About Amber Phosphorescence: Phosphorescence is the noticeably-extended emission of radiation from an illuminated subject, after the source of illumination has been removed; the atoms of certain hydrocarbons within the amber, when irradiated by high intensity UV wavelengths (LED or dedicated UV light sources), achieve a higher energy or "excited" state; the rotation of atoms becomes the opposite of their rotation in their grounded "non-excited" state, allowing for a longer release of radiation (light). The light emitted in fluorescence and phosphorescence is always a longer wavelength than the source of illumination. *Regrettably, my camera could not record the full duration of the phosphorescence of these specimens, or all other specimens (Chiapas, Sumatra, Baltic, Claiborne, Dominican), for that matter; multiple tests on all three Tiger Mountain specimens showed an average response of nearly 8 seconds, after 4 seconds of sustained direct illumination. These results are comparable to that of the Chiapas amber specimen from one of my previous videos. Source: https://file.dnr.wa.gov/publications/ger_ri21_strat_eocene_king_co.pdf

    - Subjects: Three exceptional specimens of amber, recovered from exposures on Tiger Mountain, Washington State; this is the first of two videos detailing the specimens' natural fluorescent and phosphorescent responses: 140 lumen LED light (yellow phosphor) was used in this entry. All were prepared by hand using a diamond needle file, 240 to 3,000 grit SiC sandpaper, and chromium oxide (ZAM compound) on a Selvyt microfiber cloth. - Brief Description of Deposit: Tiger Mountain amber occurs in lignitic coal seams, mainly contained within two Geologic Formations, namely the Tukwila and Renton (along their boundary); there is also a third, the aptly-named Tiger Mountain Fm., that hosts amber-bearing coal, though not to such a degree as the former two. The Tiger Mountain Fm. (roughly 2,000 ft. in depth) underlies and is inter-bedded with the younger Tukwila Fm., while the Tukwila Fm. is overlain by the Renton Fm.: the amber-bearing coal contained within the three Formations spans a geologic timescale ranging from Middle to Late Eocene in age (~41.3-33.9 Ma). - About Amber Fluorescence: The light blue fluorescence emitted by some of this amber upon exposure to LED and sunlight, bears a remarkable resemblance in color and intensity to that of blue Dominican amber. Various aromatic hydrocarbons, naturally contained within the blue variety of amber, are responsible for this fluorescence. Blue amber is commercially mined from three major sources: Sumatra (Indonesia), the Dominican Republic, and limited production from Chiapas (Mexico) deposits.

    Claiborne Amber (Cockfield Fm., 41.3-38 Ma)

    From the album: Fossil Amber and Copal: Worldwide Localities

    1.4g translucent specimen measuring (mm) 16x15x10; one side presents an unbroken exterior, with slight remnants of sand, clay, and lignitic matrix. This material was recovered from the Malvern Clay Pits, east of Malvern, Arkansas. FTIR spectrum comparison of Claiborne amber to modern Shorea sp. resin points to the Dipterocarpaceae as a probable source for this middle Eocene-aged amber.

    Claiborne Amber (Cockfield Fm., 41.3-38 Ma)

    From the album: Fossil Amber and Copal: Worldwide Localities

    4.1g rough specimen measuring (mm) 25x18x15. This is a section of a run, with successive layers grading from translucent to opaque; portions of the sand, clay, and lignitic matrix coats the exterior as depicted. This material was recovered from the Malvern Clay Pits, east of Malvern, Arkansas. FTIR spectrum comparison of Claiborne amber to modern Shorea sp. resin points to the Dipterocarpaceae as a probable source for this middle Eocene-aged amber.

    11.2g of amber dated to the Maastrichtian stage. This material was recovered from lignite beds in far-northeastern Wyoming; it generally has high clarity with few inclusions of organic detritus.

  12. This weekend I went again to the Baltic Sea coast. This time my target were Miocene deposits of lignite in the cliffs around Chłapowo. This is one of the cliffs I climbed in vain: because the only thing I found has nothing to do with Miocene - it is a piece of a crinoid stem, so most probably Silurian.
  13. This is the most incredible piece of amber ever found. its so unbelievable, that nobody takes me serious when i post images of it anywhere. Facebook groups delete it and block me for posting fake fossils. its still attached to about a foot and a half of the original tree that the sap was secreted from. that in itself is very rare and one of a kind. this part that is wood, has high magnetic attraction. the fact that its included with creatures that have never been identified before, neither in amber or out is another unbelievable aspect of this piece. notice the two creatures in blue. both were stuck on the outer most layer of the sap. with only a very thin layer of amber covering their bodies. notice how high above the surface of the amber this dinosaur looking creature got stuck. then, look at the detail of its face... the two images in blue were taken under UV light. this piece was found in north baja mexico. all of the images of creatures oin this post can be found inside this one piece of amber. nothing has been altered or added, only the one photo of the turtle has the red filtered out so that the image of the turtle can be singled out. where can i take this to get documentation authenticating that its real??? open each image to see the complete images. also if your skeptical about the inclusions or the authenticity of this peace, pm me so i can send you a video of the turtle trapped in the middle of this thick chunk of amber. thanks. shawn
  14. I've been reading about the potential for lignite to spontaneously combust, which has gotten me thinking a bit. It's mentioned in the Wikipedia page for Lignite, as well as in paper such as this: https://www.sciencedirect.com/science/article/abs/pii/S0010218002005539 I sometimes collect pieces of lignite from locations around the UK, if they preserve the shape and texture of the wood. Is there any risk of them suddenly bursting into flames? I'd have thought not, since I've never heard of such a thing happening, but then I suppose not many people collect these bits because they usually fall to pieces after a while (I treat them through soaking in a sugar solution to preserve them). Any thoughts?

    Plant material

    Hi, i wish a good day for all of you. I've visited another new place where i could find miocene plant material in a ligniteous clay.It had rain for days there and the place is covered by vegetation, so i only looked on the border of a road and i found those two items. First photos are taken in daylight, others under a magnifying glass and artificial light. The scale is in centimeters. 1)
  16. In september of 2013 a small piece of history was made in a Late Cretaceous formation here in Tennessee. In that month, I discovered a whole tree which had been fossilized to Jet! Jet is an organic mineraloid substance which is something of a rarity. Other organic mineraloids would be Amber and Pearl. A Mineraloid is something not technically a true mineral because it is derived from matter of an organic nature. In this case, this Jet could be described as a fossil, a mineraloid, or even a semi-precious gemstone. Our ancestors have had quite a long relationship with Jet which stretches back atleast to the Neolithic, like Amber, it has always been a prized material because of its electrostatic properties. So, without further ado, i wish to show the world the first glimpse of Tennessee Jet. & to be sure, i contacted The Tennessee Division of Geology in Nashville, spoke w/ the State Geologist. He was unaware of this mineraloids occurrence in Tennessee's borders....so a cross reference of the latest edition of The Minerals Of Tennessee was quickly made.....it's not in there either! (Truely, Jet is pretty rare everywhere else in America too.) So here is the first photos that anyone has ever saw of this material.....you can plainly see it use to be a tree, now it's Jet! There is an untold hundreds of pounds of this i have found....all still in the shape of a single tree!

    Possible Lignite Cone

    This specimen is late Cretaceous, formation is of marine origin. This perhaps could even be the central part of a depleted cone??? Pollen cone of some sort??? It has a hollow passing through it from end to end. It appears that it cracked somewhat and that surface area then filled in with sand.

    An Amazing Cretaceous Botanical

    This is a paleobotanical i have put the finishing touches on. It is extremely unusual for my area....the only one i actually know of. It simply isn't listed in any of prof. Berry's works, nor any later works by later botanists. It has been shown to 1 paleo botanist and 1 prof. of geology, neither gave me any feedback as to it's possible botanical source. It seems this one is pretty hard to i.d. The specimen comes from a late Cretaceous formation that is marine in origin, and very close to 80 mya. The source layer for this material appears to have been originally deposited as driftwood which in turn became lignite, @ some point iron bearing waters came into contact with the lignite, which in turn covered it over w/ a thin crust- like material. This specimen is fragile, probably as fragile as it was when deposited....if not for the ferro-type crust encasing it, the specimen would have probably never have retained it definition. Truely, i have found tons of lignites, but have never ran up on a specimen of this order. Perhaps it's a new botanic for Tennessee? To me,it looks like araucaria! @ first glance, one would sware it's a cone.....until rolling it over and seeing a branch sticking out the side! This specimen needs an i.d. badly, as,it is perhaps "new" (atleast for Tn, if not more). And the first person to positively identify it will receive credit in a academic paper that is being written. Thanks for taking the time to help.
  19. "Petrified", permineralized, silicified wood from Triassic Newark supergroup in Pennsylvania. Probably Araucarioxylon; same genus as in Arizona Petrified Forest national park. Some specimens have dark lignite on surface. For scale: silver discs in photo are USA quarter coins (0.995 inch or 2.42 centimeters in diameter).
