  1. Some of you may know me to be an avid dinosaur-egg collector. Sadly, most eggs these days come only from China or European countries. Recently, I was lucky enough to acquire a North American dinosaur egg - A Maiasaura peeblesorum egg from Browning, Montana. This hatched egg dates to the late Cretaceous, and is inflated unlike other eggs from that area. Maiasaura is the very picture of motherly dinosaurs and nesting behavior; this egg is thus one of my favorite fossils.
  2. These are a few of the pdf files (and a few Microsoft Word documents) that I've accumulated in my web browsing. MOST of these are hyperlinked to their source. If you want one that is not hyperlinked or if the link isn't working, e-mail me at joegallo1954@gmail.com and I'll be happy to send it to you. Please note that this list will be updated continuously as I find more available resources. All of these files are freely available on the Internet so there should be no copyright issues.

  3. Hello fellow dinosaur enthusiasts! I'm currently bidding on a what they say is an Segnosaurus egg on a website. I contacted the person and she said he bought it years ago also on a website. Now is the thing she doesn't have an proof of authentication and if I look around the internet all the other Segnosaurus eggs have more smooth shells. But this might be that it was found in a different type of soil. According to her the egg was found in Xixia, China. I hope one of you guys can shed a light on this if this is an authentic egg or not.
  4. Every day I look through a collection of websites and online auctions for any good deals on dinosaur fossils. Occasionally a real steal of a deal is found, but when it comes to eggs most of what I see is fake. Counterfeit dinosaur eggs are continually found, mostly being sold by the same sellers from China and Malaysia. I personally fell for this trap last year and spent a lot of money on "eggs" that were man made. This is a topic that is brought up every few months on this thread to warn fellow collectors and I think its time again to repost what many others have posted before. There was a good short article that was written by Bill Merz and distributed at last year's Tucson Gem and Mineral Show where he points out some of the most common examples of mass manufactured fake eggs.
  5. I think I discovered what looks like a fossilized egg. I have included a few pics, hope they help with an ID! Thanks in advance
  6. hi guys i love to hunt fossils and minerals, found this peculiar egg? help identify, if you need more info or pics, thanks
  7. Egg came from China (unfortunately I don't have a specific area). It came from the Cretaceous time period. Dimensions (Length x Width x height) The fossil is 12cm (~5in) x 10cm (~4in) x 10cm and weighs 2.5kg. I'm not sure what kind of species this came from however I'm curious if anyone can tell me from the pictures. Either way I'm glad I have a fossil egg of some kind even though I may not know what species it is. (I'm also I little worried that it may not be an egg at all as people do mistake fossil eggs quite commonly. However I can get a full refund so no worries).
  8. Found these online. I suspect they're fakes. Beware. Not surprising if they are fake, besides, they're from China. (not saying that all fossils being sold from China are fake.)

  12. I just acquired what looks to be a very unusual egg. This single egg comes detached from a clutch of upright eggs in an antique shop in Singapore; owner would not reveal where it origins from. The egg is white, and covered in reddish-sand matrix that can be scrapped off with a needle. This egg measures 7.66 cm long (I lack measurement of the nest, owner wouldn't let me take more pics). My first thought were that these are Troodon eggs, as "upright eggs" are a characteristic of troodon eggs as far as I know. 1) Thomas(Tom) Kapitany said these looks like it came from China. He didn't personally give it an ID, but mentioned he had seen these identified as Protoceratops before. 2) Seth Sorenson said there's no way to confirm it as Troodon without skeletal material, but he said they look like small ceratopsian eggs to him. He also mentioned Protoceratops eggs have been found in standing clutches before. 3) Laogao, a fossil egg expert from China said this looks like Troodon eggs from Henan. 4) Dr. Kenneth Carpenter said these are most likely theropod eggs of the Elongatoolithus(egg oogenera) family. Without microscopic examination or confirmation of their origin, he could not give any further identification though. With such little information, I am aware there's no way to give a definitive ID of the dinosaur that laid these eggs. I'd still like to ask for your opinions though on what you believe this egg might be.

  17. I saw a clutch of eggs today in a local flea market and took a look at it and saw quite an interesting texture on it. I have seen pictures and handled a few Hadrosaur eggs before, and I am not familiar with this kind of texture and feel and so I took a few photos to share to ask some egg experts here if this is common for a Hadrosaur Egg to look like this? Or is the specimen possibly a fake? Here are the pictures of the specimen:
  18. A gentleman gave me this object and claimed it was a dinosaur egg fossil he found on his property in TN. It doesn't appear to be any type of geode I have ever seen, but i'm unsure if it is in fact a dino egg.

  25. Hi can I get some second opinions on whether if these are Segnosaur eggs or not? They seem to look like segnosaur egg pics that float around online, but they seem to also look very much like concretion stones. So I can't be sure how you can tell them apart. Anyhow here are the pics: Specimen A: Here is another, Specimens B: Thx for the expertise and input
