This is an Enantiornithes bird found at Liaoning of China. Note the chest region in which it looks like remnant of skin (and feathers around the body too). Also, there is a pair of long tail feathers. What do you think about its authenticity?

No fossils found, but picked up a 10,000-year-old relic. Anyang river, Henan, China
hiposong posted a topic in Fossil Hunting Trips
Long time no see! How are you everyone?! Here's the story.On June 20, we had just stopped raining, it was cloudy, and I thought it wasn't too hot, so I went to look for a fossil that I had found earlier. It suddenly looked like a spindle worm. But the structure is different. I don't know what it is. Who can tell me? Trapezoid, 2cm long, 1cm wide.Found in the Anyang River. Wow, let me start by sharing with you what I had for breakfast. This kind of food is only available in our city. It's called 'Bian Fen Cai(You know KFC, we jokingly call it BFC)'.Transparent noodles are made of sweet potatoes.Green vegetables, tofu and pig's blood are added and stewed in bone broth.Why don't many regions eat animal blood? Difficult question, but we have a lot of blood food here, and there's a legend that goes back a long time.During the hunting days here, blood and guts were difficult to preserve, so the men turned them into food, bringing easy-to-preserve meat to the women and children of the camp. Digress, this is delicious. Why have I been missing for so long? In 2021, we had a lot of rain here, and my car went for a swim like this. So I can't go far away.So I went by bike. It only took me an hour. Digress again,I miscalculated. There was no sun, but the earth was steaming.When I was frustrated at not finding such a fossil, I casually picked up a rock with the stone skipping.I suddenly realized that the Anyang River had no such stones. It was covered in mud, but I could tell it was flaky mica sandstone.Between this rock source and the Anyang River, there are other rivers that isolate the sediment.So it has to do with Cultural relic. Yes, its edges are ground. There are perforations on both sides, but they're not pierced. Found some information, it should belong to the Xiaonanhai culture.Carbon-14 dates this civilization to about 13,000 years ago.This civilization is on the Anyang River, and interestingly, the earliest writing in China is also on the Anyang River.As for the fate of the stone, of course, it is donated to the museum. Ah, our city is really Historical cities. Have a good day. Wait, who's gonna tell me what that fossil is?

Are these footprints of dinosaur? It's about palm size. Found at Guizhou near the site in which Keichousaurus was found.

This is an ichthyosaur skull found at Xingyi, Guizhou of China (the type locality of Keichousaurus hui). The snout is very short and the eye socket is quite big compared to other species of ichthyosaurs found in the area. Could it be the skull of Shastasaurus liangae? The article on S. liangae is attached. ? pone.0019480.pdf

This was sold to me as a piece of Miocene feline jaw - potentially pristifelis.
GarethGP posted a topic in Fossil ID
This was sold to me as a piece of Miocene feline jaw - potentially pristifelis. The seller didn't have a firm ID and I understand because it's so fragmentary that it might just be impossible. He believed it was likely from Asia somewhere. Thoughts? Does it at least look feline?

Hello! I bought these Cambrian soft tissue fossils supposedly from Yunnan in china off of online auction site. I won them in a bid for suspiciously cheap. They seem real to me, but I’d be interested in confirmation of that. I’m also interested what you guys have to say as to what these are. Thanks! One is listed as Naraoia spinosa, the other, fainter one is listed as Vetulicola.

Hi everyone! One of the goals for my collection is to eventually own a keichousaurus fossil as they’ve come to really fascinate and captivate me. I’ve done some research externally and on the forum about how to identify real or fake or restored keich fossils and I wanted your guys’ input on this specimen I’ve recently come across. Admittedly, the prep work on this keich fossil, if real, is pretty bad and is definitely not something I’d go after, but I wanted to see if my bit of research has payed off. My guess is that the specimen is real, however, it seems to me like it’s had a very unpleasant acid prep done to it with some sort of restoration in the distal bones, possible in the tail too. What do you think? I’d love to hear your guy’s thoughts.

Marine Lizard Skeleton--KEICHOUSAURUS Guizhou Province
Lucid_Bot posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, I'm currently looking to purchase reptile material and found this Keichousaurus fossil from the Guizhou Province of China. It is being offered on a popular auction site. It is supposedly Triassic. Is this fossil genuine? Restored? Thanks for the help.

I purchased this as a supposed Silurian Megalograptus from Yunnan a while back. The seller gave me additional information that it came from the Devonian Cuifengshan Formation in Qujing, Yunnan, China. However, the genus Megalograptus is Ordovician in age. I'm not really familiar with eurypterids, so maybe it's not even a sea scorpion. It certainly looks like some kind of invertebrate though. But maybe it's just indeterminate debris.

benthic phototrophic macroalgae indicate taht 'Snowball Earth' might have been 'Slushball Earth'

This is a partial skull of an ichthyosaur from Yunnan of China. There is a big circular part below the skull, is it a detached eye socket?

Hello, Could I get an identification for this fossil from the Cambrian of Yunnan, China? It was described as a "Chancelloria", but I don't know if that specific genus is described from this locality and the sclerites aren't star-shaped. It may be a related Chancelloriid, and it seems there are several described from China. My best guess is something like Allonia: https://www.researchgate.net/publication/316342674_Chancelloriid_Allonnia_erjiensis_sp_nov_from_the_Chengjiang_Lagerstatte_of_South_China http://www.paulselden.net/uploads/7/5/3/2/7532217/zhaoetal2018small.pdf I wish I could get higher-res photos of the sclerites but unfortunately I don't have a camera besides my phone. PS. Also, what could that grey+orange conical object next to the Chancelloriid be? Part of a trilobite genal spine?

So I purchased 19 assorted Miocene-aged teeth from (according to the American seller) China a few years ago. The seller had given most of them a vague label (which I've labelled the pics with) - but wasn't able to get more specific. Could anyone help me narrow down which species they might be? Are there resources people are aware of that could help point me in the direction of being able to ID these teeth? Or is it very unlikely I'll get any definitive ID on these and I'll just have to accept a broad family-level description of what they are? I attached an extra picture of a giraffid tooth from the same collection - I reached out to a Chinese expert on miocene teeth from china and he believes "that it's a lower right canine and that it might belong to Palaeotragus or Palaeotragus-sized giraffid based on size". I thought FF members might find some interest in that.

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.

Partial Jurassic Neuroptera Insect with Beautiful Wing Preservation
Biotalker posted a topic in General Fossil Discussion
Here is my recent acquisition from Inner Mongolia of China in the Jiulongshan formation, more commonly and famously known as Daohugou, which dates to middle Jurassic around 165 mya. The part and counterpart partial insect fossil appears to be a neuropteran, perhaps related to the family of Grammolingiidae (a group of lacewings that include “Jurassic butterflies”, so named on account of their huge spotted wings). Only one of the wings and a small part of another were found in the fossil. The wing, however, is slightly more than two inches (5cm) long. The head and thorax but not the abdomen are intact. I am sharing these images because I think the fossilization is remarkable. Dense tissue like the head and thorax are harder to interpret than the thin wing. But wow, the details that can be seen under the scope are amazing! No ambiguity as we sometimes see with dragonfly fossils!

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.
