  1. Good morning! I have a question. How old is the copal from Montagne d'Ambre in Madagascar? I recently purchased two such specimens with insect and plant inclusions and I am delighted with them. The age given in scientific literature is: 1-2 million years, 100,000 years, 50,000 to 60,000 years, 1,000 years, several hundred years, even 300 years. What is the truth, or at least which of these answers is more likely?
  2. I recently obtained this piece of amber, which was described as being from Myanmar, and therefore of cretaceous age. I got it very cheaply, I'd say (from a well known auction site), and this led another collector to rather rudely assert that it was fake. I have no reason to assume that it is fake, but at the same time, I'm having trouble proving that it's authentic. When I poke it with a hot needle, the needle makes an impression but doesn't slice straight through it. Dark grey smoke rose from it, which didn't smell of plastic. When I rub it vigorously with a soft cloth, it gives off a mild resinous aroma, but doesn't get sticky. It floats in salty water, in the same way as my Dominican amber does (my Baltic amber slowly sank, but I suspect I didn't have enough salt in the water). I haven't been able to get it to hold a static charge, but then I can't with any of my amber, so I must be doing that all wrong. I wouldn't normally post most of these pictures, because all but one qualify as photographic failures, but I've since re-polished the surfaces for future photography (my spare-room studio being out of action at present). Note a seed (?) of some kind just above the antenna, near the top, and some kind of larva or something to the left of the millipede. That looks like a tiny beetle on the left hand side of this one. General inclusions, including bubbles and an insect 'riding' on one, centre-right. One of the pseudoscorpions. There are various other inclusions too, including another pseudoscorpion and one tiny spider. I don't see any way in which this is an out-and-out fake (e.g. plastic). So that leaves the possibility that it's authentic, or copal, or that it's amber with the insects inserted afterwards. I'm very doubtful of the later, because they are randomly placed in the amber and I don't see any signs of tampering. That would seem like a lot of effort for something sold for £35/$45. It doesn't seem to have any of those little oak hair things that you get in Baltic amber. Not sure whether cretaceous amber, or copal, have those or not. I'd welcome any thoughts on this. Thanks.

    Amber or Copal?

    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

    Gigantic Chunk of Amber?

    I don’t know from which locality this specimen originated. I found it among my late grandfather’s property. From what I can gather, this is an extremely large specimen of amber. It weighs approximately 110 lbs, measures approximately 22” x 18” x 11” and features many interesting inclusions from what i can see. I’ve performed a scratch test, hot needle test, acetone test, smell test, saltwater test, UV light test, and specific gravity test… all of which seem to confirm its identity as amber. If this is true, however, based on the information I can find, it would seem that I’ve come into possession of one of the largest pieces of amber on record. You can imagine my skepticism at having made this discovery in a small neighborhood in southern Indiana… I haven’t a clue what to do next—please help!
  5. 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 sandstone matrix, and the clarity is variable throughout the piece.

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

    This specimen weighs 8.5g and measures 34x29x20mm. It contains several dual-phase bubbles (some with mobile gas bubbles), with one being quite large; a translucent layer surrounds most of the chambers. The piece originated from the La Guajira Department of Colombia, and was recovered from deposits/diggings several miles south of the Cerrejón Coal Mine; the depth(s) of these diggings, and the copal-bearing sediments' geological age are unknown, though some sources claim it comes from the same Paleocene strata found in the Cerrejón mine to the north. Still, this material reacts quite readily to acetone and other mild solvents, and cannot be considered to have undergone substantial polymerization (i.e., it is not a mature fossil resin).

  10. 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.

    Madagascan Amber Copal

    From the album: Robs Fossil Collection

    Hand polished piece of Madagascan amber Copal. This Copal has not had a definite date put upon it yet, but it is thought to be a similar age to the Columbian Copal, so that would place it in the Pleistocene age until more accurate dating. It is thought that similar environments around the world at that time created amber copal that has formed almost identical to each other and the insects are similar too, if not the same, just like today. Copal Size: 5.5cm
  12. 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.
  13. Hello everyone! I was just curious as to what you think of this specimen. I'm aware users here are (understandably) very sceptical of lizards in amber/copal, so I'd love to hear what you have toto say about it. Here are the details: Species is unknown From Colombia, thought to be from Pliocene/Pleistocene The lizard measures 30 millimetres. Total measurement with copal is 50 x 40 x 0.50 mm Full image: Base - partial tail and leg, with one foot visible on the right Torso - possible predation? Also note the little stump where the leg should be. Head - possible mineralised blood above head? Note large bug on the left Bugs located at the top, to the right of the head
  14. 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 through with the exception of the mysterious dark object lurking on the middle. (queue the spooky music!) Personally I think that both of these may just be dirt that accumulated in a crack when the copal was forming a long ago but this has apparently been a topic of hot debate. So if ya'll got any opinions on the matter, I'd love to hear them...or if you don't want to share your opinions, just tell me that I've discovered some weird new sub-species of dinosaur and I'll be happy with that. lol

    Calling Bug People!

    I bought this bit of Madagascar copal a year ago, then finally got a decent microscope to see the bugs this week. They are less than a mm each. Now I'm stumped. I am a certified *modern* naturalist. I know something about insects. This one fits all the defining characteristics of an adult insect - probably Coleoptera - except that I only see four legs and may or may not have had antennae at some point. The heads are not very clear at any angle. On the bottom view, there are nubs at the end of the abdomen that *could* be legs, but that is the wrong place for insect legs. On the side views, it looks like there might be legs folded backward, as is common with some beetles, but the underside view also does not show any attachment points where there might have been legs that broke off. Any paleo-entomologists out there to point out what I am clearly missing in these pictures?

    Amber? Copal? Any ideas?

    I inherited a friend's mineral collection. Lot's of interesting specimens of turquoise, petrified wood, crystals, etc. He lived in New Mexico and I know some of the pieces are from U.S. southwest area. That's about all I know. This one's a mystery, and he really didn't have any idea either where it came from. Has a strangely organic look to it though. Any insight or thoughts will be appreciated. Thanks!

    Copal.jpg

    From the album: MY FOSSIL Collection - Dpaul7

    Copal SITE LOCATION: Columbia TIME PERIOD: Recent Era (several hundred to several thousand years old) Data: Copal is a name given to tree resin from the copal tree Protium copal (Burseraceae) that is particularly identified with the aromatic resins used by the cultures of pre-Columbian Mesoamerica as ceremonially burned incense and other purposes. More generally, the term copal describes resinous substances in an intermediate stage of polymerization and hardening between "gummier" resins and amber. The word copal is derived from the Nahuatl language word copalli, meaning "incense". Copal that is partly mineralized is known as copaline. Grimaldi (1996) referred to copal as subfossil resin, several hundred to several thousand years old, that may take a high polish, but will craze deeply on the surface after only a few years when the volatiles from the original resin evaporate.
