  1. I bought this a few years back and I was wondering if it was amber, copal or plastic. It was labeled as Baltic Amber and it has a spider inclusion in it. Are there any tests I can do to it that are pretty reliable and will not ruin it. I put it in salt water and it sunk to the bottom. Not sure if the mixture was correct. I have a saltwater fish tank and I used water from it for the test because it is the same mixture as ocean water. Thanks for any help.

  3. Some of you may have heard of Boucot's compendium of fossil behaviour. This could/should be in there,if it isn't already ulrichfausectB50H12S5.PDF
  4. Hello, New to this forum. I recently have developed an interest in fossil inclusions in amber. After buying a number of prepared pieces, I decided I would like to try my hand at polishing some of my own. I found myself the owner of several hundred pieces of Dominican amber with inclusions. I have been doing a wet sand, and feel like I am close, but the pieces just don't seem to be getting a nice clear transparent finish. Any tips for finishing? I attached a few photos, the piece with the winged ants is from my collection and was polished by someone else, just for contrast with the one I was working on. I have a few pieces that look like they may have rarer inclusions (one looks like an earwig), so I am hoping to perfect the technique on a few more common pieces before I try my better ones. Thank you! Nathan
  5. I promised someone some literature on Amber. A bit of an experiment for me,because i'm searching now ,at this very moment ,and not proceeding from what i have on my Pc. conserve NB:i don't know what's in Fruitbat's Lib,haven't checked(yet).Everybody should check out that awesome resource
  6. Hi all, I picked up this piece of amber because of the interesting coprolite (caterpillar, I think). Anyway, it also has an interesting flying insect with a white substance surrounding it. The wings also look like they have some sort of protrusions along the edges as well. At first I thought it was some sort of spider silk, but I can't see any fibers. The only other thing I could think of was some sort of parasitic fungus. It was really hard to get a good photo of it. Are there any amber experts out there that have come across something like this?
  7. Could anyone recommend a reputable supplier of Cretaceous amber? thanks!
  8. Lets talk about amber! I would love to pick the brains of experienced collectors. I have done a lot of internet searches and read topics here on this forum, but I would love to know more. Right now I only have one piece (might be copal), that was a gift from someone who went to the big rock show in Arizona. I would love to go to that show myself someday! I have always been fascinated by the little worlds that are in the depths of amber. I would like to buy some more amber for my new collection but I feel the topic is so complicated. The prices range so much for what to the naked eye appears a very similar piece. Best advice on buying amber online? Is it, in your opinion, worth buying rough amber and polishing it yourself? It seems like an interesting treasure hunt! Any thoughts on this inexpensive amber coming out of Indonesia? Any good? Would you ever buy amber where the location it came from is unknown or unrevealed? Does anyone buy in bulk, sight unseen? Advice on storing and safely displaying? Anyone ever coat their amber with anything (wax, polish, etc) to help protect it from changes in temperature and humidity or damage from light? Any help or advice is greatly appreciated! If anyone has photos of their favorite specimens, or specimens you discovered yourself from a rough piece of amber, I would love to see them.

  10. This specimen came from the Baltic Sea of Russia. There are two male non biting midges present in the specimen. Their from the Eocene about 44 million years ago. Photo taken with microscope at 40x magnification.
  11. I am looking for fossil amber (no copal at this time, unless it's something really unusual). Locality is not important. I have a ton of Pleistocene, Pliocene, and Miocene fossils from Florida - most of them are from the Peace River locality (Bone Valley formation, Hawthorn Group). If you have some surplus amber to swap, let me know and maybe we can work something out. Reply here or message me to inquire.
  12. "The tail of a feathered dinosaur has been found perfectly preserved in amber from Myanmar. The stunning discovery helps put flesh on the bones of these extinct creatures, opening a new window on the biology of a group that dominated Earth for more than 160 million years. Examination of the specimen suggests the tail was chestnut brown on top and white on its underside." http://www.bbc.com/news/science-environment-38224564
  13. Hi Whats is insect it ? Burmite amber.
  14. Just found this article about amber that was found containing a feathered tail of a dinosaur. Pretty fascinating! Enjoy http://news.nationalgeographic.com/2016/12/feathered-dinosaur-tail-amber-theropod-myanmar-burma-cretaceous/
  15. Can anyone please help identify this insect? According to the label, the amber is from the Dominican Republic, dated to the Oligocene. Right now I'm guessing this is a black scavenger fly. Thanks in advance.
  16. Recently in the news there has been a lot of discussion about a feathered non-avialan theropod /coelurosaur tail that was found intact, kept preserved for 99 million years in amber. Here is the study published about it: http://www.cell.com/current-biology/pdf/S0960-9822(16)31193-9.pdf and a Nat Geo article http://news.nationalgeographic.com/2016/12/feathered-dinosaur-tail-amber-theropod-myanmar-burma-cretaceous/ On an awesome-ness scale of 1 to Sue, where do you place a fossil find like this? (Feel free to insert your own subjective fossil scale criteria, as well as swapping Sue for another fossil that reperesents a perfect 10 to you) -Curious Fossil noob
  17. this just arrived in the mail today and i thought i'd show you guys, especially since sumatran amber is a new dicovery. this is a 10.1 gram semi rough piece of Blue amber from sumatra, Indonesia, and is early miocene in age. it has a small window polished into it but other than that, it is a rough piece. i may post better pictures that show the blue more, like in the middle of the day.
  18. Has anybody been to a Sayreville amber collecting site lately? Do they exist still? I am working nearby and was hoping to try my luck if I can get away. I've found small pieces on the West Coast but I've read about Sayreville for years. Thanks
  19. Just showing off some of my digital photography with Chiapas Amber. Chiapas amber is some of the highest quality and most difficult to obtain amber in the world. It is harder than most other ambers. Mexican amber is mined from the state of Chiapas, in Southern Mexico, where the veins running through the strata are estimated to be some 24-30 million years old. Here, the amber was formed from the resin of an ancient tropical tree (genus Hymenaec), the same genus of tree that produces the prized amber of the Dominican Republic.

  22. 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 modern epoxy resins), and the tacky resin becomes hard. For all practical purposes, the hardened resin is a "plastic". Exactly when the resin becomes amber/copal, or a fossil, is not definable by any scientific criteria. I would like to see if others have the same thoughts. I am also attaching a picture of the best piece in my collection. "Best" meaning my favorite. This is one of my favorite articles. The following is by Dr. Robert E. Woodruff Emeritus Taxonomist, Florida State Collection of Arthropods Resins are produced by many trees and other plants; Frankincense of the Bible is one of these. Peach and Cherry trees produce resins that children often use as chewing gum. No botanist or paleontologist knows when resins were first produced, but we know it was probably more than 100 million years ago. They are produced to heal wounds, just as our blood coagulates to seal injuries. There is no doubt that these resins have been produced continuously since they first occured. Because they are affected little by the elements, resins are similar to their original form. Only a few volatile oils are eliminated by time and burial (e.g., in marine sediments that are 3000 ft. elevation now). We use Canadian Balsam as the most permanent sealant for cover slips on microscope slides. Unfortunately, no one can presently date these resins by any definitive tests. Because they have been continuously produced, there are no drastic changes from one geological period to another. We can infer age, if we know the age of a sedimentary deposit in which they are found (this would be a minimum, because older material could have been redeposited). There are those (including several scientists) that insist that the word amber must be reserved for certain age resins. With such a continuous resin production, and no clear dating, it could all be called amber. It is a semantic argument, & those who sell Baltic, Dominican, & Mexican "amber" do not want to use the term for any that might be more recent. Obviously a commercial bias is present. They prefer to use the term "copal". Strictly speaking, the Aztec word "copal" is used for all resins! They do not distinguish the Miocene deposits from southern Mexico from the recent resin collected for incense today. Therefore it should not be redefined to fit some new arbitrary definition based on age. It is considered lower class only because of these commercial interests. We have Cretaceous amber (at least 65 million years old) and much Oligocene & Miocene amber, as well as Pliocene (Africa), and many others. We have no dates or specific geological information on Colombian amber. Because of it's color and hardness, we believe it may be Pliocene or Pleistocene (as is some of the Dominican amber from Cotui). Studies underway may clarify the deposits, but evidence suggests that there may be varying geological formations & ages. Mankind (depending on the anthropologist's definition thereof) has been on earth only 3-5 million years. Certainly the Olduvai specimens are fossils (both men & animals) and extremely valuable for study of human evolution. If we assume the Colombian amber is this recent, it still has extremely important value for those studying the fossils. Studies of biodiversity, biogeography, ecology, and evolution, all benefit from the scientific description of these amber fossils. Age is relative, the old man said, but old is not necessarily better. To call the Colombian material anything other than amber is a misnomer! Logically, we should just call everything "resin", with qualifying adjectives of origin or geological formation. I doubt that this would be acceptable to most "amber" dealers!
  23. A friend of mines father found this washed up on a beach many years ago. We think it may be amber but we are looking for confirmation. He has done a few basic tests and he thinks it is amber over copal. Has many insect and plant inclusions, and probably weighs over 20 lbs. Anyone able to confirm this? Is there a way we can easily, definitively find out if this is amber? Thanks coin pictured is a US quarter.
  24. It is a very cool and nice amber. Do you have cool ambers?
  25. I found a great specimen in burmite amber, including a neuropteran eclosing from its larval case. The larva ('ant-lion') can be seen clinging to the leaf, and the adult form was captured emerging; Its wings have yet to expand, etc. and this is a genuine piece of Cretaceous burmite. It shat 3x after eclosing, and there's a homopteran & coleopteran also captured inside. Besides being spectacularly beautiful and crazy timing, I can't seem to find any other instances of such "metamorphosis in the act" in the fossil record... Certainly nothing 100 Mya, with a showy lacewing, and in such clearcut detail. Even the grass(?) is partly preserved where the larval form clung. Any thoughts, pointers, points of reference? Can anyone possibly identify the subfamily or genus? Aquatic or terrestrial "ant-lion"? The images are purely for reference/informational purposes in this forum (not my own), and thanks for any helpful discussion.
