From the album: Fossil Amber and Copal: Worldwide Localities
6.4g specimen measuring 40x25x14mm (see related entry). This is incredibly-rare material, with next to no information available on it; this copal originates from sandstone deposits and can be found both in-situ and ex-situ. This particular specimen was recovered from a farmer's field in rural Costa Rica many years ago, and is part of a small lot of similar material; unfortunately, the specific location of the deposit this specimen came from is unknown. This material is noticeably harder than Colombian copal, but still reacts to acetone; the exterior of this piece has a slight layer of sandston© Kaegen Lau

Indonesian Red Copal (Subsoil to Surface Horizons, Late Holocene)
Barrelcactusaddict posted a gallery image in Members Gallery
From the album: Fossil Amber and Copal: Worldwide Localities
This specimen weighs 36.0g and measures 65x40x25mm; several small fragments of plant material are contained within its translucent, reddish mass. Originating from the island of Java, this variety of copal is a fairly recent discovery; it is recovered from various soil levels, near to or on the surface of the rainforest floor. Rough specimens usually exhibit a thick, whitish exterior crust; Indonesian red copal is very soft, reacts readily with acetone, and can be scratched with a fingernail. -
Hi everyone, I am new to this forum and have been loving it. I found a very fragile ammolite preserved in mudstone (I believe) and I want to seal it to preserve it and prevent it from falling apart. What can I use? Can resin/epoxy be used?

I’m a fisherman and I’ve just done a trip on a Beamer trawler. We were fishing 20 miles south of lizard point in Cornwall and caught this in one tow. The skipper and his father both said they’ve seen this before but it’s not common, neither knew what it is exactly. It was in one lump but my fellow crewmen hit it with a rail pin and it split. Can anyone tell me what it is? It’s very pretty and I can see loads of inclusions when I hold fragments up to the light. It also smells strongly of pine.

Ok so I was thinking of using resin to coat a skull I have in my collection. Its rather pricey so I wanted to make sure I could protect it from any further damage. The skull appears to be coated with something already since I see a shiny texture in some areas, so should i bother using a resin on it as well ??

I was encouraged to share this in the forum so here it goes. I was given a pile of "amber" and two pieces that may or may not (most likely not) have something inside. After the "amber" failed the saltwater float test it was proposed that I may have copal, NOT amber. I tried my best to take as clear of pictures as my camera phone would allow. The first piece supposedly it has a "bug or stick or something" inside. The copal, if it really is copal, does not appear very clear, even with a light source behind it. The second piece is a little more transparent when the light shines throug

What do you use to back thin fossils? I have some nice pieces preserved in shale which came up pretty thinly. I'd like to reinforce to make sure they dont break. Thanks Liam

I am quite new to preparing and preserving fossils and am not very knowledgeable on resin coatings. I have been told that Poly Methyl Methacrylate has some similar properties to Paraloid and can be dissolved and used to coat fossils. Is there a reason it is not used for this purpose? Thank you very much for the info.

Genuine amber not releasing smell when heated.
MarielleK posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone. So I have a question about a piece of burmite amber in my collection that I am certain is authentic. It does not release a smell when heated...I've found that my darker colored specimens will release a stronger pine smell than the lighter colored ones, however. Why is this one not giving off any smell? I'm sure it's being heated to a temparure high enough to release the smell. It passed the saltwater test, distinguishes from copal with the acetone test, and has cracks and chips characteristic of amber. It has a rather large inclusion of half of some species of grasshopper. I've -
Hi there, I am looking for accurate replicas of actual dinosaur fossils: claws, teeth, skulls, skeletons, etc. I have seen several different resin replicas floating around eBay and Amazon, etc. but I am not looking for toys or other enhanced replicas or cheap models. I am looking for actual casts of real specimens, something worthy of a museum (maybe not museum price though?). I am especially interested in claws and skulls, both for reference material and display. Something durable too, so no ceramic, glass, etc. Does anyone know of a reputable site for this? Also,

I have been doing some recent work with Columbian Amber/Copal and thought I would throw this out for a general discussion. It is fun, if nothing else Most of my life I have believed that there is no difference between Copal and Amber. I know chemically there is no difference between the two. Amber/Copal from the same plant from different time periods, even millions of years apart are identical. Fossil resin's molecular make-up is mostly carbon and hydrogen atoms that form hexagonal rings. Molecular bonding between the rings increases over time (called polymerization, as in moder
