Good afternoon All. I have another mystery from Alberta. They are just little fragments, (3) but they were all found in the same spot, so may be associated. They have a blue surface, but no other colours. My first thought was ammolite, but there is absolutely no green or red. I did google blue fossils, but came up empty. Does anyone know if blue can happen to any fossil, or is it a trademark of one particular group? I apologize for the low quality photo, I even took them out into the natural light, but this phone camera is the worse. thank you!

A few finds from this weekend. Fortunate enough to have a cottage on Lake Erie, fairly close to Rock Point Provincial Park which is known for it's exposed fossils of a 350 million year old coral reef. About half were found on the beach itself and the other half in the crushed gravel part of the driveway. I'd imagine the beach will keep yielding new finds after every storm, here is hoping for it anyway.

Hi, I'm brand new here. I enjoy being out in nature and collecting bones and rocks I find. Just the other day I found this jaw bone on the banks of a creek near my house in El Dorado County California. It looks to be the size of a cow or horse jaw. I would love to know what animal you all think it is from and especially how old it looks. The blueish color of the teeth has me really intrigued. Thanks for any ideas.

I found this in an abandoned fish nest in a human-made lake. One of my favorite finds!

I had the opportunity to cruise around Wyoming, Colorado, and Utah on my own for 5 days The first day of my fossil hunting excursion was to be spent at the Petrified Blue Forest site in Western Wyoming. Having been there before, I knew fragments of wood abound, many carrying the blue agate on it. But I was determined to find a “large” log this trip. I had researched how to up my odds and stopped at a hardware store the night before and purchased a shovel as step one. So early that morning, I found myself looking out at the vastness of this “forest” thinking where to start. That is when this antelope startled me. After a short stare down both the antelope and I were on our merry way. Soon after stepping out of my vehicle to scout around, I began finding many small pieces of petrified wood with the characteristic blue agate that everyone is after. Here is a piece of wood next to a skull that I do not recognize. Any thoughts about what animal this was? After an hour, and not finding anything substantial, I jumped back into the car and followed an obscure path that led me to the top of a hill. From up here, one can appreciate the vastness of the region. Looking around told me that petrified wood existed even up here. So out came the shovel again. The ground is made up of a loosely broken sedimentary like rock that can be shoveled with some (much) difficulty. As I dug, my eyes were intently focused on the hole created looking for a hint of an algae fossil that has a very distinct look to it. Why look for algae???? Because within the algal mat is where the wood lies! Finally, after many digs, some significant algae appeared in my hole. Here is a picture of it as found and the debris surrounding it removed. A piece of the top layer of algae is removed, exposing the wood inside. Unfortunately, when I tried to wedge the log out of its hiding place it split in two, leaving this piece in tact and the other piece in a crumbled mess. Thank goodness I had purchased a small container of acetone at the store and I immediately added it to the Paraloid B 72 crystals I had brought with me from Minnesota. This stabilized the intact piece fairly well, though I could have used many more resin crystals than what I packed. The Blue Forest wood was deposited into a fresh water, algae filled, shallow lake that was full of silica. Soon after the fresh wood was deposited in the water, algae formed a thick crust around it. Here is a small branch showing the layering of algae. The wood with time shrunk, providing space for the silica rich water to do its thing!!!! In addition to the mineral deposits, this wood has exquisite preservation due to the algae blanket protecting it from the elements. Here is a piece that shows the boring holes by insects as fresh as if they were made today. Now some of my specimens brought home. Unfortunately, the specimens found on top of the Butte contained mostly yellow calcite crystals. Next time I will stay down below and hope for much bluer specimens. Here is a branch that was completely mineralized!!

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

Any idea why these little bones are blue? (I know the look a little green here but in sunlight they’re much more blue.) Found a very remote place in Central Turkey.

Tiger Mountain Amber (Upper-Tukwila/Lower-Renton Formations [Boundary], Middle to Late Eocene)

Incredible blue fluorescence in amber from Tiger Mountain, Washington State, U.S.A. No longwave UV light has been used here; these select pieces fluoresce in the same LED light conditions as Dominican blue amber, and with a strikingly similar coloration. Commercial quantities of blue amber have been officially described to be found in the Dominican Republic, Indonesia, and Mexico (Chiapas); to my knowledge, blue amber has never been described, much less documented, from North American deposits. Total weight is 0.4g, each piece measuring only a few millimeters in length. In the fluorescent video & image, specimens were submerged in water in a borosilicate glass petri dish; also, an additional video and image of the subjects when dry. *Please note there are several condensed air bubbles on surfaces of amber and glass.

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

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

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

Hello! I've been to the main digging site in the Blue Forest of Wyoming a couple of times but would like to try a couple of other sites there. Does anyone have the directions to the other digging areas? Thank you!

Location is in Missouri The area is dated to the Pennsylvanian most likely Raytown, Wyandotte Limestone Formation At this pile I hunt at there are many concretions, but none exude the blue coloring as they are mostly black and much smaller. I am not 100% sure these are fossils but these are the only weirdly hued fossils I have found there. I have found a few teeth from Eugeneodontida, Horn corals, Crinoids, Brachiopods, Nautiloids and petrified wood from the area. I do not have any measuring tools that are not wood when I took these pictures. I apologize and hope this could be a decent size reference.

Hey all. I'm looking for some fossil wood that is a dark blue. Something similar to the color of lapis. Most of the blue forest wood I've looked at is more black than blue. Does anyone have any suggestions?

Couldn't dig because of a shoulder injury, so I took a little walk instead.
