Rovno Amber (Mezhigorje Fm., 33.9-28.1 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Roughly 12g specimen of amber mined from the Klesiv Deposit of the Rivne region in the Rivne Oblast of Ukraine. It was originally coated in a 2mm red oxidized crust, typical of this locality. It is believed that the presence of this crust is an indicator that amber from this particular locality underwent little to no re-deposition throughout its diagenesis, and oddly contains the majority of described insect-included Rovno material.© Kaegen Lau

19.0g specimen of hand-polished amber from the Rivne region of Ukraine. It contains numerous botanical debris, although I have not observed any definitive insect inclusions. It is what would be termed a "run"; this specimen has over 12 successive layers that would have run down the side of the tree (the depicted piece would be properly-oriented if rotated 90˚).© Kaegen Lau

Rough amber from an old site near Coalmont, British Columbia. The original site is now closed to collecting, since a mining company somehow got a court injunction and has "jumped" the owner's legal, active long-standing claim. The claim owner has informed me that he is not able to collect larger specimens (>3g fraction), as he had been able to in the past.© 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
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 approximately 30 Ma (Oligocene, mid-Rupelian); the amber-bearing strata of this formation is located at a depth of approximately 32-39 m, and is composed of hard, banded coal (sub-divided into two layers of slightly different grades, 2.5m and 4.5m thick). I have 15 pieces, and these are the ones I haven't yet pre-formed. The piece in the upper-right corner is pre-formed (diamond needle files), and it is ready for increasing grades of sandpaper (240-3000 grit), and a final polish with a denim cloth and polishing compound (ZAM).© Kaegen Lau

Rovno Amber (Mezhigorje Fm., 33.9-28.1 Ma)

83.8g raw amber mined from the Rivne region in Ukraine. The "eye hole" was likely formed when the organic matter (i.e., tree branch) the resin encased, was likely dissolved/washed away during the resin's diagenesis and redeposition (Baltic and most Rovno material is generally believed to have been redeposited).© Kaegen Lau

43.7g rovno amber from the Klesiv deposit, Ukraine. The thick, oxidized crust (≈2mm) is typical of material from this specific area; when backlit, it appears a deep cherry-red, but this is only due to the oxidized layer.© Kaegen Lau

Associated Cenozoic sea turtle carapace from Summerville, SC lag deposit
fossil_lover_2277 posted a topic in Fossil ID
So I just finished piecing together the remains of a partial sea turtle carapace that I dug out of a lag deposit just outside the town of Summerville in South Carolina. Anyone potentially know any taxonomic information on it, such as what genus or species it might be from? Conversion from inches to cm: 10 inches = 25cm; 5 inches = 12.5cm; 1 inch = 2.5cm

This was found between glacial and non glacial quaternary sediment. Slightly north of Ocean shores, WA. NOT on the beach, but where the forest meets the beach and erosion is occuring. I brought this to the only fossil shop local to me and all they recommended bringing it to another shop hours away so trying my luck here! You can see the vertebrae which after taking a soft brush to curves around in the shape of a I, the clearly visible vertebrae at top are the largest in with, however the length of each remains the same as the width lessens. There are at least 9 vertebrae I can count. The width starts at .25", there is 1" of vertebrae exposed prior to curving back up, 2" total exposed vertebrae. Curious if where it starts curving are joints? You see in pictures where it curves that specific block looks different from the rest. What is your best ID guess? Thank you so much!!!

Dear collectors! I'm curious If someone interesting for my collection of Mollusc, mainly gastropods and bivalves from tertiary of Europe. I have more than 1000 specimens! I'm open-minded and accept all offers! I am interested in quality fossils and NOT quantity!

I need help identifying this fossil, or eliminating possibilities. I found this while searching for Native American artifacts and other fossils. It was in a stream. Found in North East Nebraska. Geologic research says the area it was found is within the Ogallala formation from the Tertiary Period. Several members of a FB group think I might have a fossil fungi and have asked for samples,, which I am reluctant to attempt to chip off myself. Several of the photos show signs of fungi. I know that fossilized mushrooms are extremely rare in the fossil record, usually only being found encased in amber, and never in physical form. Thanks.

Hello, A colleague of mine shared some pictures of an interesting rock she found. It was found loose by a creek in the Denver area. It looks to me very much like an inner era, although it may well be something else. None of us are able to positively identify it. I'm sure someone here can confirm whether or not it is a fossil, and what it might be. The creek in question flows from the east, and my understanding is it would have to be a tertiary or quaternary fossil if it is indeed a fossil.

In preparation for a planned outing next week with my oldest son to hunt for fossils in the Lincoln Creek formation, I went to an outcrop of the local Blakely formation this afternoon, and now that I'm primed to spot concretions, I saw a few right away. I only grabbed one to bring home (just had a small bag), but I may go back and grab some more later. Since I lack the proper tools to prepare a fossil that's in a concretion (at least for now!), I just used my trusty hammer. I'm not really seeing any fossil remains here, but it does have a really interesting funnel shaped part coming out of one side. Maybe it's some kind of burrow that later filled with different sediment? Or just purely geological? There's also a lot more of the center bit to expose, but I didn't want to keep whacking once it shattered, since I'll probably just destroy any fossil remains that are in there. Anyone have any thoughts on this? Should I try to whack it one more time? Toss it? Secure it back together and save it for another day?

So I found this one near Tukwila Washington. I think the first one is just a clam of some kind and the second one I have NO IDEA. If anyone has a clue please let me know. I can take new pictures if needed. (Area I collected it from was in a mountain in Tukwila (more like a huge hill) and it used to be a shallow ocean back millions of years ago)
