Whole dinosaur eggs are highly sought-after fossils. The ones usually available to collectors are Hadrosaur eggs, Oviraptor eggs and Segnosaur eggs from China. This thread deals specifically with hadrosaur eggs. Hadrosaur eggs (Dendroolithus sp.) as we know from the market are in fact various dinosaur species, often hadrosaurid (many collectors/dealers lack the tools or discipline to examine eggshells under microscopes or have accredited museums examine them). Commercially available eggs vary greatly in price, anything from 150 USD to 1,500 USD depending on quality, size, hatched/unhatched and prep work. They usually range from 3.5 inches to 7 inches in diameter, and are mostly hatched types (which means the egg is in fact empty. If you prep out the bottom matrix, chances are it's hollow). However, hadrosaur eggs are also one of the most commonly faked, or mistaken fossils in the world. Anything from pieces of rock, pebbles, septarian nodules, concretions, or even chemically-etched objects are sold as eggs. There are several online right now. Here are examples of false hadrosaur eggs we often see in the market. Here are examples of partial/composite hadrosaur eggs (Note these ones are real to an extent. They can be a more economical choice as long as you know what you are getting).

Hello, I'm wondering if the pictured fossil is a genuine one, or a forgery. I can see that the fingerbones seem to be painted, though I'm not sure about rest - it seem a bit sketchy, with the oddly round "dots" around the bone structure, and a bit obvious touch-ups by brush on the "seam" of the broken matrix (close to the leg). The neighboring insect also seem odd (especially the front, with brushstrokes...) I'm aware that the piece is touched up/enhanced, though I'm wondering how much of the real thing is in that frog? It's supposed to be a chinese Genibatrachus from Liaoning;

Hi, just want to share with you one of my specimens and would like some opinion with regards to the potential ID of this theropod indet. tooth from the Yixian Formation in Liaoning province. As I have little familiarity with Chinese theropods and don't see a whole lot of real specimens reference pics available unlike their Moroccan or USA counterparts. Any input or insight from experts or experienced collector would be greatly appreciated. Here is the tooth in question and it's details that I gathered: The tooth measures about 1.5" measured straight with some visible restorations on the specimen This is the cross-section of the tooth taken from the base: This is the up-close visual of the distal serration: The serration extends down to the base with a serration count of approximately 3 serrations per mm. This is the visual of the mesial serration side: The serration extends down to only about 1/3 of tooth and the serration count is also approximately 3 serrations per mm Please let me know your thought and appreciate all opinions, thank you in advance!
