Hi my name is Roanne.New to this site.I recently hiked out here in northern Arizona where a freiind of mine told me they found fossil eggs. I did come by a spot where it looks like the so called eggs got washed down the mountain. We are talking more than one size egg here. Arizona's climate is quite different than other parts of the us. I find tons of petrified wood all over my yard.,in every color you can imagine and so much different types of rocks and minerals all in one location.When we flooded way back when dinos roamed the earth, wouldnt they have gone to the highest points to live and lay there eggs. So why couldnt these possibly be from way back than.? I did crack a few of them open and definetly looks like something was there.

Hello, I found these "fossil turtle eggs" up for sale on an auction site. The seller claims these "authentic" turtle eggs were found in Bulgaria. I highly doubt these are even eggs, they may just be concretions. Just to be sure, I'm asking whether these are real or not.

Found this on the Frio River after a good rain. It has round crystals unless they are eggs. I also thought it could be coral. Can anyone tell what this is?

We've all laughed before at the nodules/concretions sold as eggs on popular auction sites, either by the ignorant or deceitful. However, most of the things I've seen advertised previously have been at least moderately egg-shaped. Not so with these stunning examples, which tend more towards being rock-shaped. I can only imagine how valuable these ordinary rocks - the exceptional colour and beauty of which are plain to see - were to the native Americans. I think it is a reasonable conjecture that they kept their favourite ordinary rocks in some sort of display cabinet, or possibly locked away in some kind of safe, to negate the risk of theft. I can now only marvel that these beautiful ordinary rocks have survived intact, and were not made into grinding stones, carved into bows and arrows, thrown at buffalo, or used to prop up tables on uneven surfaces.

Hello together, i bought a pair Oviraptor eggs and i want to prepare them. But i don´t know what preparation technic is the best way? Please can you help me? Thanks you very much! Kind regards, Michael The Fotos are from the Seller, i will make some better ones in the next days.

Hello, I have some unusual rocks would like to know if anyone has seen anything like them before. Thank you for your time.

Hello! I was wondering if first, someone knows of a website where I can figure out if what I have is an egg and second, where I might sell it if it is the real deal. I appreciate any information! Thank you.

Hello! Everyone has probably heard someone say here and there that they have found a dinosaur egg!! Although most eggs are very rare to find and you are very lucky if you do have the pleasure of finding one. I found this along with lots of other fossils in the same area. Just curious to know if you all think it is real or just a rock that is a look alike. This was found in Missouri in a small town of Fairdealing.

Just thought I'd share something cool. There's a little rock shop in my city that I like to visit every once in a while. Although most of the fossils they sell are nice little ammonites, orthoceras, shark teeth, etc., they've recently acquired some specimens that blew me away: a couple of solitary raptor eggs, a raptor nest, and a hadrosaur nest! I couldn't believe my eyes when I saw them. I asked one of owners of the shop where the fossils were from and I was told the raptor nest was from Madagascar and the solitary eggs were from South America. I didn't ask about the hadrosaur nest. Questions regarding their authenticity and legal nature immediately flooded my mind as I'm not familiar with the laws of those countries regarding fossils. They also look to me to be incomplete but I'm not sure. Personally, I believe the nests (assuming they're real), should be in a museum or institute where paleontologists have access to study and learn from them, but who could resist the thought of being able to say you own a freakin raptor nest!? Maybe put it on display in your mancave with a plaque that reads: "Dont touch my huevos!" Anyway, let me know your thoughts. Have you ever been in the presence of a fossil that truly astonished you for whatever reason? e.g. your favorite dino, a significant discovery, etc. I'd love to hear your responses.

This great question from Auspex a couple years ago can now be answered in the affirmative. Up until now there have been a few close calls but nothing conclusive. The earliest reference to alleged trilobite eggs was made by Joachim Barrande in 1872. C.D. Walcott also published a brief paper in 1877 and each of these were subsequently disproved by Percy Raymond in 1931. Zhang and Pratt 1994 also reported on possible eodiscid embryos but had to concede that they may have been produced by another soft-bodied arthropod. Now at long last we finally have what appear to be bona fide trilobite eggs. Not surprisingly, the remarkable preservation of pyritized Triarthrus specimens from New York have yielded this highly anticipated fossil gold. Pun intended, Enjoy! PYRITIZED IN SITU TRILOBITE EGGS FROM THE ORDOVICIAN OF NEW YORK (LORRAINE GROUPE): IMPLICATIONS FOR TRILOBITE REPRODUCTIVE BIOLOGY Hegna, Thomas, Martin, Markus, Soriano, Carmen (2015) Geological Society of America - North-Central Section - 49th Annual Meeting (May 19-20) Paper No. 20-3 - Presentation Time: 8:45 AM Despite a plethora of exceptionally preserved trilobites, trilobite reproduction has remained a mystery. No trilobite has preserved unambiguous eggs or genitalia. This study reports on the first occurrence of preserved, in situ trilobite eggs from Triarthrus eatoni from the Lorraine Group in upstate New York. Like other exceptionally preserved trilobites from the Lorraine Group, the trilobites are replaced with pyrite on their exoskeletons and ventral appendages. The eggs (presumably representing unfertilized eggs) are spherical to elliptical in shape, about 50 µm in size, and are clustered in the genal area of the cephalon near the lateral border. The eggs are only visible ventrally with no dorsal brood pouch or recognized sexual dimorphism. This location is consistent with how modern horseshoe crabs carry their unfertilized eggs. Trilobites likely released their gametes (eggs and sperm) through a genitalia pore of as-yet unknown location (likely near the posterior boundary of the head). If T. eatoni’s reproductive biology is representative of other trilobites, they spawned rather than mated and exhibited r-strategy reproduction.

What is this? Petrified frog eggs? The spot are dark green!

Hi everyone. I've come across this hadrosaur egg on a well known fossil/gem dealer's site. It's described as from the "Xixia Basin, in the Henan province of China", which research tells me has an embargo on hadrosaur eggs. It's a very well known gem/fossil site selling it, and states "This fossil specimen will come with a certificate of authenticity." (Authenticated by who exactly? Sure...) Naturally these pictures are as good as the resolution gets, and the price point (over $1k USD) seems pretty high risk for a possible fake. I've stayed away from eggs in the past since they're so rampantly faked, but eventually want one (from any dino, really) for my collection. Thoughts? Thanks!

Do whole eggs from North America ever come to market? They seem to be scarce in their entirety. I've seen a fare amount of Maiasaurus shell fragments around, but far fewer than eggs from other places. Doing an internet search I see some eggs labeled as Troodon from Montana, but even the pictures are poor and limited. Why are there so few dino eggs from North America? Have they just not been found well preserved? Has anyone seen one or own one?

QUOTE "As the oldest direct evidence of a creature caring for its offspring, the discovery adds another piece to our understanding of brood care practices during the Cambrian Explosion, a period of rapid evolutionary development when most major animal groups appear in the fossil record," said Jean-Bernard Caron, curator of invertebrate palaeontology at the Royal Ontario Museum and associate professor in the Departments of Earth Sciences and Ecology & Evolutionary Biology at the University of Toronto."

Hello its my first post on the forum. I need help with identifying this egg fossil.

What do you guys think about this Hypselosaurus egg from France? Good specimen? Authentic? Fair Price (1500 Euro = $1676)? This is only the second French Egg I've seen for sale since I started collecting a few months ago. Seems less crushed than other eggs of this type. This is an egg i do not know much about... Here is the listing: "Hypselosaurus priscus Extreme rare Titanosaur egg, No restoration!!!! OLD COLLECTION 1950 Maastrichtian, Cretaceous 70 million years old Trouvaille, Bassin d'Aix de Provence, France Size: 6.6 by 5.6 inch / 16.5 by 14 cm"

I picked up some crab nodules that they were getting rid of at the lab (due to lack of provenance). They think they came from a place called Thompson Gulch, but I'm not sure where that is. I was looking at one of them under the microscope prior to prepping it and discovered what looks to be either coprolites or eggs that measure just under 1 mm in length. However, when I looked up modern crabs, their poop appears to have a long pellet shape and their eggs look round. Any ideas on whether these are coprolites or eggs?

I recently purchased 2 Hadrosaur eggs, they were once joined but the matrix joining them has split (they can still be positioned as they were together, just with a visible crack where the split is). As they are heavy, fragile, and already split I want to display them and keep them safe, here's what I'm thinking: I have a plexiglas tray (thick) that they fit in nicely. I want to create a ground-cover like base that they can sit in, which will have some indentations to keep them from moving, and wanted to make this look like sand or riverbank mud as they would be found in their original natural state. Essentially making a nest or backdrop of their natural surroundings. Then I would place a plex cover to keep dust out. Rather than just fill the tray with sand (which would be messy, likely not too accurate, and wouldn't keep them in place), I want to pour in a wet material that I can sculpt and will dry to a nice base. Any suggestions on what to use? I could use plaster but that will add weight to an already heavy display. Ideally the material could have integral color (redish brown like the muddy matrix these eggs are found in), and some sort of a silty-sandy texture. I'm curious as to what others have used, done, or could suggest for my project. Thanks!

Hello friends ! I got nice amber piece with many insects inside. There we got a spider, many flies, amazing Trichoptera with colour eyes and super Fly laying eggs (!). Nice action scene trapped more than 40 million years ago trapped more than 40 million years ago ...

TURTLES: The most often seen fossil in the Nebraska and Wyoming Badlands are TURTLES. They can be several inches from hatching to three feet and weigh several hundred pounds. Turtles are so common, yet as a complete specimen... they are scarce. Some exposures I have hunted "Badland Fossils" had so many turtles weathered into pieces, I refer to those areas as "Turtle Gulch" and "Turtle Valley". Not that they were on top of one another, but one great death bed... One level of outcrop where multiple specimens were entombed and eventually eroded out today. Virtually no other fossils are found with these mass death levels. No Oreodonts... which any Badland Fossil Collector would be very surprised. The one I recall most vividly was on the exposures of Shalimar Ranch. These were all two to three foot specimens... no smaller turtles were weathered or weathering out. The reason I even bring up "Turtles and Eggs" are they are both have immediate eye appeal to the finder and to the curious. Skulls and teeth have their novelty, but turtles and eggs... they have an instant recognition of current live specimens and these ancient ancestors. It was during the Oligocene that the entire fossil fauna and some invertebrates like the Helix sp. snails, have modern relatives, or most had others not gone extinct. We had mice, rabbits, deer, camel, horse, rhino, birds (at least as various sized eggs), lizards, snakes, etc.. This is WHY the Oligocene Badlands relates to fossil collector and the public. Turtles. I myself have encountered what I would describe as three kinds. Stylemys, Testudo and Graptemys. By far, the Stylemys is the most frequently found turtle. Although at times I refer to them as tortoise, I will leave that to Forum Members who might have spent more time studying them. It is shaped like your box turtle and I have found them 3 inches to 3 feet across. Some times you will find loose plates where rodents had gnawed. Since these turtle could not retract their heads or legs, you almost never find one with a head nor appendages intact. Skeletal parts, bone can be found in the interior, if you wanted to remove the matrix to find out or not. When one is found with a skull intact, the skull will be partially exposed from the carapace and orientated such that the skull actually stayed intact when buried. My last Stylemys with skull attached with a carapace that was "heads up" and tail down position when found. The carapace had a "lump" of extra matrix which enclosed the skull. My first and last with a skull intact! This is probably only of interest to some of you who have actively hunted Badland Fossils. Exposures extent as far North as western North Dakota, Montana, Wyoming, Colorado, Nebraska and South Dakota with the best exposures. There are in Paleontology... splitters and lumpers. I guess I would be a liberal lumper. The splitters find any excuse to describe a "new species" and the "lumper" would explain them as male, female, juveniles, etc. I would imagine a Stylemys of South Dakota might be different from one in Central Wyoming. But for now, I recognized three distinct shapes in Nebraska. One that caught my attention, late in my collecting days, was a turtle found in Niobrara County, Wyoming at a ranch that would be considered Chadron Member of the White River Formation. Not far from this turtle was a weathered skull of a Hoplophoneus saber tooth. The badlands had a light green tint... which to an experienced White River Formation fossil hunter... pond water or river channel. It was not a river channel as is was not gritty and full of Titanothere parts. A pond. And weathered upside down was a turtle... which ended up being the first "pond turtle" or aquatic turtle I had ever found. I add several photographs with this post. A pond turtle find was unusual, but it was bottom... up. It was upside down. I took the entire block of light green matrix that it was within and prepped it so I could pick the turtle up and replace it into the matrix. When I flipped it over... the top carapace had Hoplophoneus upper canine punctures! This is why I felt this story was necessary. Obviously cats liked pond turtles, too. Not far from this pond turtle I found a weathered Hoplophoneus skull... skull and no skeletal parts. Other than the turtle and cat... there were no other fossils in the general area. Just odd, This finishes the story of my Graptemys inornata pond turtle. EGGS: Mostly referred to as Duck Eggs because of the similar sizes. But there are also smaller bird eggs found. Most eggs are the hollowed shell that has filled with clay (Badlands). The eggs show the exact detail of the porous nature... much like our common chicken egg. The brown Chalcedony eggs I have seen were entirely north of Crawford, Nebraska. These eggs had been XRayed to see if any bones existed... and at that time none were found. Even the "badland" filled white shelled specimens also have never given up any secrets... yet. The majority of egg finds are associated with the Chadron Member and mostly in the green tinted sediments... ponds. The eggs were laid, the pond had excessive runoff into it, flooded the nests and... presto... buried to be found 38,000,000 years later. Where one egg is found... others are sure to be weathering out in the future. I have found most of mine as sporadic in white fine grained badlands. North of Crawford and north of Harrison, Nebraska, Often they are "crushed" with cracks along the compressed edges. I have found a few weathering out of the badlands and some weathered out in the Chadron "flats". My theory on Eggs is that those found are infertile. This explains why no near hatchlings are to be found from XRays of perfectly preserved eggs... as delicate an egg is to fossilized... there is no reason why one or more would not give up an unhatched chick. Had there been a unhatched chick... when buried the decomposition of the chick, would expand the egg and prevent it from being preserved as a fossil egg. Breaking into parts and little chance of preservation. I have never found loose egg shell. I have never found any bird skull and leave a possibility of bone... if complete enough to distinguish it from a large rodent bone. Just have not been that lucky. In a way, this is intended to enhance your knowledge of two well known fossils of the Badlands. This does not include possible turtle eggs and the beetle pupae that I suspect... but nobody has found any among a large turtle, as far as I know. So my not knowing exactly what the turtle egg looks like, leaves a big vacuum in knowledge. I have one "possible turtle egg" that is round with unusual cracking about the diameter of a nickel, 3/4 inch. I found it digging around some odds and ends this morning in storage. Reference for Turtle Collectors: I recommend one book concerning Fossil Turtles. Strange enough there is a similar title... but Fossil Lizards, which also occur in a good variety in the Badlands. Fossil Turtles of North America by O. P. Hay- 1908- Carnegie Institution of Washington Fossil Lizards of North America by Charles W. Gilmore- 1928- National Academy of Sciences Why, you ask does Ray go on about some subjects? When I was first collecting, it was very difficult to get any information on my fossils. Common, unusual and very rare. It was a challenge. Now I have the majority of references and no place to hunt in the near future. So for those of you who are so fortunate to be still active, please make use of these references.
