Hello! I asked this question in the Facebook group so I apologize if any of you are seeing it for a second time, but it was buried in a comment chain so I’m hoping to get a few more expert eyes on it. I received this beautifully prepared Keichousaurus today and it’s truly awesome to see it in person, but now that I’m able to inspect it more closely I’m thinking it may be a composite. There are a few things making me lean that direction: 1) There is an obvious mismatch in the patterns on the matrix, both front and back, when comparing the chunk that the body is on to the chunk that the skull is on. For example, the partial fish fossil on the righthand side just abruptly stops at the seam (last photo, blue arrow) … but it’s maybe possible that this is due to variable flaking/weathering and reattachment 2) The head is dorsal while the body is ventral … but I know it’s possible for this to happen naturally if the neck is twisted 3) The white “veins” that appear to run across both plates (skull and body) are, I think, true calcite veins in one plate and scratches intentionally placed to match on the other. For example, the red arrow in the last photo points to a junction where a true calcite vein from the body plate should cross the skull, but no vein is visible in the skull. A “vein” reappears above the skull but I believe this is just a surface scratch. On the other hand, the skull is perfectly sized and aligned to the “horns” (retroarticular processes) present on the body plate. This seems incredibly difficult to achieve in a fossil of this size. This specimen was prepared in the US and I have no reason to believe the skull is fake, but the uniform spacing and shape of the teeth also looks off to me. That may just be due to incomplete preparation of the area, I can’t tell even under 10x magnification. In any case it’s beautiful to look at, I was just a little disappointed to see that it may be a composite. What are your thoughts?

Oviraptor Egg Authenticity
dkurbel posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, I'm new to the site. Can you help me determine if this "Oviraptor Egg" is authentic? It was purchased from a popular auction site and received less than a month ago. It is claimed to have been purchased from a Japanese collection which originally purchased the egg from its original owner in Mongolia in the 1980's.

Hello. I found these fossils for sale and thought they looked interesting. I am new in the hobby and this is my first time I am thinking of buying an eurypterus. I wanted some opinions before I proceed if they look alright and which of these two in your opinion seems nicer (I know it is personal the matter of opinion but I would love to read your opinions).

I need some reassurance about some trilobites I want to buy. I believe in my rookie eyes that they look alright but as people told me before in this forum I want also some opinions before I proceed as I am new.

Hello to anyone reading this. I want to know if anyone has been involved with AAPS and if anyone has purchased anything from their members. If a fossil dealer is a member of AAPS can I have confidence that they're selling genuine fossils? I would like opinions from anyone who knows more about this. Thank you.

Hi, my daughter is into gems, fossils crystal. So we have been getting into it too. A few years ago in Canada we came across an antique shop where we bought a Megladon tooth as the owner was a prospector by trade and said he had found it in North Carolina. No certification but looks cool. It is small weighs about 3.3 oz. I was wondering if anyone can tell if it is real or a fake? Thanks for your help!

Brachiosaurus Bone Fragment Authenticity
King Butler posted a topic in Is It Real? How to Recognize Fossil Fabrications
Ok a website I was looking at is selling what it claims to be pieces of Brachiosaurus Bone. I cannot post photos because I would incriminate the seller, but the piece looks genuine enough. What I want to know is the likelihood of it actually being Brachiosaurus. By my understanding their fossils are quite rare so even a small fragment of the genuine article would not be cheap, these ones are offered at 19 dollars. According to their information, their pieces comes from a Brachiosaurus femur from the Morrison Formation in Utah. The Morrison Formation is the right, and as I understand only, place to find such fossils if this was genuine but it's also a place were other sauropod fossils are found. They also include an image of some fossil bone that I assume the piece was taken from, but it's give no true scale to it or shape. It sounds a little to true good to me, but what do you all think based on the info they provide. I personally doubt it, but I thought it couldn't hurt to ask. -

Doubts about iguanodon jaw fossil authenticity
Sergio Barbeira posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello to everyone! This is my first discussion on this forum. I have just started to collect dinosaur fossils and I wanted to learn from all of you. Specially to identify a real fossil from a fake one, if that is possible. I have found an interesting fossil that I would like to purchase if it is authentic, but I have several doubts. The fossil is an Iguanodon Jaw (see pictures attached) discovered in Isle of Wight, UK. The dealer says that this bone belonged to an iguanodon that would have lived approximately 120 million years ago. They also told me that the jaw has been restored from two fragments that had broken naturally; both these pieces are associated and from the same animal. What do you think. Any clue would be appreciate. Thank you so much!!

Keichousaurus - real, fake, altered?
Wrangellian posted a topic in Is It Real? How to Recognize Fossil Fabrications
Came across this one and wondered if it was fake or doctored. I have my suspicions - for one, the legs look disproportionate, but I wouldn't know. I wouldn't mind having one of these if it's real and the price is right. This is the only pic available... maybe not big enough to tell anything for sure? but I know some of you have a pretty good eye!

Could experts share the primary indicators to check for regarding authenticity of a Mosasaurus jaw specimen? - specifically root / tooth junctures.

Authenticity of these pieces? Jade? Aventurine? Malachite?
Gemstonefreak posted a topic in Rocks & Minerals
Could someone help me classify these stones?

I found this on a golf course in MA. It is so symmetrical and resembles other seemingly legitimate eggs here. The continuity of the surface and lack of "inclusions" make it hard for me to think it's a rock. Any thoughts ? I can send better pictures to those who may care..... Thanks. -Bill

Greetings Fossil enthusiasts- My sister brought me a wonderful gift when she got home yesterday. It will always keep its sentimental value to me, but I'm curious if this fossil is real or fake? I've been looking up and down all over the internet and I have no clear cut answer so I'm hoping one of you can help me. I have a hunch it is a fake of some sort- but it's still neat nonetheless. I appreciate any and all feedback. Thank you, and have a wonderful day friends. Pictured is the specimen flipped to show both sides.

I've recently bought this fossil from a seller on Instagram and these are the seller's pictures, but after some recent digging, I was introduced to the reality of counterfeit and fake ones. Does this one look real or fake? The seller doesn't have location of discovery and I've been trying to google how to learn whether it's real or fake but I haven't gotten far. Thanks for your time!!

Hello everyone, I am a total novice, interested in buying a spinosaurus tooth to start my collection. I have been trying to do my research into reputable online dealers. Generally I have found that a few well-known sites are recommended (paleogallery, arizona skies, indiana9fossils, etc). Recently I stumbled across a site called Fossils Meteorites and More. They also are listed under the same name as sellers on ebay. Their prices seem reasonable but I hesitate to buy without have heard anything about them. Does anyone here know of this dealer? Appreciate the help!
