May I ask your opinion ? hadrosaurus egg (of course.. :-)
Apollo 15 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello from Switzerland. I'll be happy to write some lines in the member introduction forum this week-end, but I must admit I need help regarding this egg asap. It'll be offered in a auction house in France next week. Provenance China, Xixian, Hunan, 6.6 inches long. I read here all the pages regarding fakes, but it's hard when you're a newbie (I'm an amber collector) regarding dino eggs.. Thanks in advance, Jacques.

Could I ask everyone’s opinion. I purchased some Amber from China. I was told it was real, but I am not sure. I tried the salt water test and it does not float with two cups of warm water and a quarter cup of salt. Another piece that was purchased from a reputable seller does float. When I add A lot more salt then it all floats. Can anyone help me? Here are some photos with and without UV light.

Xixia Amber (Gaogou Formation, 100.5-85.8 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Amber Xixia Basin, Xixia County, Henan Province, China Gaogou Formation (100.5-85.8 Ma) Total Weight: 10.1 grams Overview: These pieces are all unwashed and still have an extremely fine layer of sediment; each has high clarity and rich color, many are naturally droplet-shaped, and individual measurements range from 1 to 8 millimeters in length. A few fragments of coal are also present within the lot. Prevalence, Inclusions, Botanical Source: Amber itself is quite common within the Xixia Basin, hosting China's largest amber reserves, but despite this is very rarely seen on the market. It has also been studied very little, mostly due to the fact that biological inclusions have not been known to occur in it. An araucarian source for this amber was determined based on chemical analysis. Geological Setting, Associated Fossils, Age: Amber occurs as lenses and droplets within the middle unit of the Gaogou Fm., in fine-grained sandstone which is non-marine in origin; the middle unit measures up to 440 meters thick, and also contains dinosaur egg and bone fossils, of at least 6 different genera: the presence of some of these species indicate an age of early Late Cretaceous. At other nearby amber sites (Wuliqiao Town) the presence of ostracod and bivalve fossils indicate a slightly younger age (middle to upper Late Cretaceous). Plant and pollen fossils are not known from the amber-bearing strata at Wuliqiao Town. Given the alluvial setting the amber is found in, and the absence of plant macrofossils in the matrix, I feel it may be possible that the amber was redeposited making it somewhat older than its host strata.

Is this a Zhuchengtyrannus tooth? I am currently looking for better photos from the seller. If the seller sends me a picture, I will post the picture. Production area information Xingezhuang Formation from the Wangshi Group, Zhucheng city, Shangdong, China

Recently, I learned that Chinese fossils are prohibited by law from being transported outside of China.I have a question. Can I buy fossils that have been transported outside China before a law banning transportation outside China is enacted?

A seller as a precambrian fossil listed as Eoandromeda octobrachiata. Is it this species or is it something else. It comes from guizhou China.

A well prepped keich? Must be fake.
JBkansas posted a topic in Is It Real? How to Recognize Fossil Fabrications
I haven't seen keichousaurus with hollows in the matrix like in this specimen (but they don't look like the bubble defects from a replica mold). I'm guessing it's real but I've never seen one without all of the prep damage that is typically present..thumb.jpg.f0dc8fbde9aa1f2428c7977aea627cf5.jpg)

Hello everyone, I recently came across some fossils posted on our favorite auction site described as Onychodont teeth from Yunnan, China. This immediately caught my eye and I decided to send in a very low offer, not expecting to even purchase or bid, just to see how much the seller might ask for a fossil like that. Surprisingly the offer was accepted, and after a few weeks this fossil arrived. It's a 3cm long tooth on a Limestone matrix with other fragmented remains from fish. I know that identifying Devonian fish teeth is something that is very difficult to do, so I am not expecting that it can be done with this specimen, but I wanted to know if there's any reason to believe it could've come from an Onychodont like the seller claimed. Additionally, I asked the seller where in Yunnan this was found and I was told it comes from Wuding County, I was wondering if by any chance anyone might know what formation this may have them come from, I looked it up and a number of fossils described from the Haikou Formation come up, although I couldn't find much more info on the formation itself to confirm if this could be the origin of the fossil. As always, thank you for reading and any assistance you may be able to offer.

Keichosaurus real or fake?
sokastar05 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, everyone. I am a first time poster. I received a Keichosaurus fossil as a gift. My grandfather purchased it many years ago in Alberta, Canada at a gem show. Could you please have a look at the pictures I took and let me know if you think this fossil is real or fake. Thank you kindly!

I'm looking at purchising a fossil that is labeled anomalocarid. It's not super well preserved, but looks like part of an anomalcarid arm. Is it an anomalocarid or something else.
