Hi all, This eggshell fragment is from the Two Medicine formation in Browning, Montana. I'm trying to figure out if it's smooth enough to fall into the Troodon camp or if it's a worn down specimen that previously had ornamentation. I'm leaning towards Troodon eggshell with calcite coating. Thanks!!

"Titanosaur eggshell."
FossilSniper posted a topic in Is It Real? How to Recognize Fossil Fabrications
Claimed to be from the Cretaceous of Argentina. Dimensions are 30 * 29 * 6 mm. No additional information provided. Thoughts? -
I have inherited a 3 generation fossil collection from my grandfather. I will start posting pictures based on what I think is the most valuable and interesting. starting with this reptilian looking egg with an iridescent blue reptile shell it's absolutely phenomenal! roughly 3 and a 1/2 by 2 and a 1/2 inches Let me know what you guys think It's so intriguing it seems like it has an energy of its own when you hold it.

Curious if this "elephant bird egg" is real. The length and width are realistic and it weights about 3 lbs. 14.5 oz. It is smoother than I expected and appears to have been polished in places, especially in spots where some of the sections meet. Surface covered in fine lines (often with branches) as well as small holes. A small flake was examined under a microscope, showing one of the fine lines to consist of a series of holes. Other holes were also visible. I dabbed the flake with vinegar and observed bubbling under the scope. Images show some close-ups of the textured

Hello, I thought I'd share my eggs and eggshell collection. Eggs are all from China. Eggshell are from different places. All of these eggs from China. I hope to add a French egg at some point, and some other types from China.

I enjoy egg and eggshell and wish to buy this. It is from Hell Creek. I don't have any from there. Does anyone know if it is actually eggshell and actually from there? I do not know where ID of triveratops comes from. Seller says was done by paleontoligst and he is relying on their info which they got by comparing to Asian eggshells (protoceratops maybe?). Unless a Triceratops nest has been discovered? I do not think so. Seller took extra photos, but throgh the glass of the frame as he could not open it. Picture 1 look like oviraptor-type eggshells to me. As does picture 3. Pictur

Hello, Any thoughts on this eggshell? Seller has a lot -- all from Nanyang in China. And sold as a bulk lot. But, of the three close in examples, can anyone ID them? I'm especially interested in the top most one. It has an unusual pattern to it with lots of long lines. There was a thread I had, I think from here, about ID'ing fossil eggshell and the different textures, but I can't find it now. Thanks The one on the right looks to be oviraptor?

Hello!! I’ll get right into the backstory. I bought these together, labeled as “Tyrannosaur Eggshells”! Unfortunately they came with no other information They are (as you can see from attached photos) pretty small chunks. I was taken aback by how cheap they were, I’ve never bought dinosaur stuff before though so I’m not sure if that’s a normal price. What you can’t see in the photos: -has glittery and small crystal-like structures that shine in the light. Mostly on the sides of the shell. -Not particularly heavy. Seems to be lighter than what a rock their size w

Think you found an egg? Read this first! Dinosaur Egg Guide- Basic
CBchiefski posted a topic in Fossil ID
The Basic Dinosaur Egg Guide Many people often mistake a concretion for an egg, to help clarify what is a concretion, and what is a real egg, here is a guide. A quick overview with examples: How to spot a concretion: How are they different from eggs? A concretion is a rather common rock made of tightly compressed minerals. Typically, concretions are a smooth sphere or oval with little to no surface texture or just a few bumps. Often nearly a perfect sphere, sometimes more of an oval. In a concretion, there- 14 replies

One of my favorite fossil types. Dinosaur eggs come in all shapes and sizes — from an oval as small as a thumb, to a sphere as big as a basketball. These fossils are often faked by the hundreds, if not thousands, in Chinese factories (China is also the world's richest source of true dinosaur eggs). However, there are also many natural-occurring objects mistaken as dinosaur eggs such as concretions or even fortuitously-shaped rocks. Despite these hurdles, dinosaur eggs remain one of the most desirable of all fossils. NOTE: Dinosaur egg and eggshells, by their nature as an ichnofossi

The Advanced Dinosaur Egg Guide Please share this with those who have egg questions. When possible, technical terms were avoided or defined. Every effort has been made to ensure accuracy, but it is always important to do your own research. This guide is merely a snapshot of information taken from many scientific publications. I am not an expert on eggs, rather I just love sharing what little I have learned over the years, what science has learned over the years. For an overview on how to spot a fossilized dinosaur egg and the sizes of eggs, see the basic guide:

Hey everyone. Little compensation after a unsuccessful and rainy school day My 31 Megaloolithus eggshell fragments have arrived! Very happy with this Dino egg bundle since I did not have any before and bought them all for nothing. Some of them have really stunning detail. A special thank you to everyone who helped IDing them as Megaloolithus . A nice addition to my Dino collection. (Also bought 2 trilobites from the same seller including an Ampyx I will soon be posting .!) Hope you like the post. Kind regards to everyone.

Eggshell experts out there, came across this fragment said to be Pyroraptor South of France. This is the only picture provided...is it rare and is it Pyroraptor?

David Evans and crew from the ROM have been collecting in the Hell Creek of Montana instead of their usual Judith River localities. They have not reported finding much but today's Twitter feed David posted these pictures and commented "We found dinosaur eggshell today! It’s a rarity for the Hell Creek Formation. Thanks to Wendy Sloboda for her expert help finding it.". Have never been lucky enough to find any and like David indicated they are pretty rare in the HC. @-Andy- @HamptonsDoc @CBchiefski hazard a guess what type they are?

I have a large group of dinosaur eggshell fragments from the Nanxiong Formation of China. As they're isolated fragments I know its difficult to narrow them down to any particular oogenus, but I was wondering if it is possible to say anything about them just by surface texture alone? From what I can gather, eggshells with nodes and ridges from this formation would indicate a theropod eggshell, where as the smoother eggshells are more likely herbivour (probably hadrosaur). I've added pictures of each type. I've struggled to find a lot of detail on Nanxiong eggs which

Hey guys! I'm curious about this egg fossil I've got here – it's been preserved with its hollow shell intact and sort of crystalized. I know there are loads of these eggs out there, but I've never seen one like this before so I'm wondering how unusual it really is. The other egg seems to be solid when held under a bright light. Here's what I know about it: – Ophidienovum sp – From a snake, I think – Tertiary/Miocene – From Mainz, Germany – Eggs are 2cm long Would love to hear your input!

Hi all, I have come across numerous theropod eggshells sold as "Oviraptor from Mongolia" through the years. Mostly, I pay them no heed. As I am aware, whole Oviraptor eggs from Mongolia are in fact Elongatoolithus sp. eggs from Guangdong or other parts of China. True Mongolian eggs are very rare. What about these eggshells though? My guess is that thousands of them come out of China, the same way as the eggs and egg nests. But then again, eggshells are more common, and is it that implausible for some of them to be Mongolian in origin? I label mine as being from China, b

I traded some fossils for a bunch of European dinosaur eggshells a few years back, a mix from France and Spain. However, I stupidly misplaced the labels for these two sets of eggshells and now have no idea which site they came from (they appear to be from two different sites, judging by the colouration). I know it's a long shot, but if anyone with an interest in European dinosaur eggshells could shed some light on where these eggshells came from, it would be much appreciated. All are around 2mm tick.

I recently bought this fossil which is a dinosaur eggshell that came from China. It is late cretaceous in age. You can even see red coloration which is the remaining sediment from where it was collected from. I want to know which dinosaur layed it. I think the fossil is Elongatoolithudae which is the type of egg that Oviraptorids layed. Front The back which is very smooth
