Hello. My grandmother found this probably in the 1920’s. I have conflicting information. Some say is dinosaur egg, some say sedimentary geode. I must admit it looks nothing like the other geodes she and i collected together but perhaps it is. Thought i could get your opinions on this. Probably found in central texas although she never said where she got it. Thank you for your help. I can take better photos if these not good enough. Just let me know. There are no crystals inside.

My father lives in SE MN, south of Rochester. He lives on a farm on top of a hill and has been doing a lot of topo work. In doing so, he has discovered that almost every rock he picks up has what appears to be seashells and fossilized plants in them. His research led him to conclude that the fossils are in the range of 400 million years old. The other day he was walking his land and saw what he thought was a potato sticking out of the ground. He picked it up and was puzzled. It feels hard like a rock, is smooth, and most shockingly it glows when light is applied to it. Is this an egg of some sort?

This egg is from Jiangxi, China. There are white deposits inside the egg. Are these bone fragments of an embryo?

Hi i came across this Egg label as oviraptor egg from China look quite real to me( but not quite sure tho) what do you think about this? thank in advance!

Hi, Found something resembling an egg in a field. The area is Jurassic inferior/Triassic. It's not the best pictures but if you aren't sure i can take more in the morning. Can you identify it for me?

I’m sure it’s not, but I’m not sure enough not to ask. I read the “is this an egg” post and am still not sure. There’s just a few pieces of the superficial layer left. It’s textured and has a thin outer layer: so, is it an egg? found Judith river formation along the milk river in Montana. thanks for the help

Hello and good evening everyone. I have a rather large curiosity. length is 25” X 14 1/2” X 6” estimated weight is 125 too 150 lbs found in Rogers Arkansas around Beaver Lake in or around 2012. I purchased this as a conversation piece to go in my waterfall that I am putting in my back yard and was very intrigued by it when I purchased it from an old friend. I’ve been told it is a dinosaur egg also have been told it is a Turtle? If it is a Turtle I cannot find where any of the openings would have been, head, legs or tail opening or a seam where it would have closed up? Hope you enjoy this, it’s very intriguing.

Hello everyone. I am here due to a recent purchase of a egg or something petrified? I am currently working on a waterfall project in my back yard and have been collecting Rocks / Stones for it and I remembered a friend years ago had said they found a dinosaur egg? I thought, what better thing to have for my waterfall for a conversation piece than a dinosaur egg! Long story short I bought from my friend and now am very curious what it is? Egg? Turtle? I have heard both so I here to find out and explore all of your findings as well. Will post my find next. Pleased to meet you! Chuck

I’m new to the whole artifact and fossil hunting and actually forum posting! I would like to get opinions on this following find. It was found in a creek in SE Missouri. And any pointers on hunting and identifying would be greatly appreciated. Thank you

hello everyone ,my name is meysam pls help me I found a Spheric stone Is this a dinosaur egg?

I know there are tons of 'not an egg' look alike rocks but as they don't seem to resemble this one I will venture to ask...my daughter found this in a shallow riverbed on our camping trip last week to central Connecticut. The brown shell like pieces are thick and uniform. There are some in the opposite side as well, will upload more pictures. This pic was taken the day of the find. Any insight would be welcome. My daughter is 4 and pulled it out because we were discussing all the different colors of the river rocks. This one looked nothing like the others. A man we had chatted with the day prior lives close to the riverbed and had spent the summer doing a lot of rock stacking and moving lots of the river stones around to build these rock nests in the water for his toddler to play in. A lot of the areas we were wading in were spots he'd been uncovering and relocating rocks. ANYWAY - any comments are welcome. Thanks in advance.

An egg that I’ve recently acquired but not sure on the family or species it’s belongs too. I was thinking troodon based on the shell texture and size which is around 3 to 3 1/2 inches long any ideas? I have it in between 2 other eggs I have on the left is segnosaur and on the right is a protoceratops egg.

For the purpose of this discussion I will refer to my find as an egg. Even though it may not be. I found this “egg” at a quarry in Southeast Michigan. I have done as much research as google will allow and still am not confident on its identity. On a side note I found another fossil in the same area that I am pretty sure is a type of brachiopod. Not sure if that would help with the identity of my “egg”.

Good morning, please take a look at this artifact I discovered a few weeks ago and help me identify if this is something other than a rock with unique features and patterns. I have spent FAR too much time closely inspecting it and I'm convienced that it is something other than a naturally forming rock. Altough I'm not an expert in geology, I have collected thousands upon thousands of artifacts which is one of the reasons this one clearly stood out to me. The color, shape, pattern, and texture is very distinct. Please note that this artifact is not whole and has been broken in half. The photos are top down. What I see is a fossilized creature curled up in what could be an egg or borrow. It looks to be reptillian based off the patten of what could be the underbelly on one side of the fossil and the shape of the what I believe woud be the snout of the head (again it has been partially broken off). Also, there seems to be a long tail that wraps around the circumfrence of the unit and centered in the middle is the snout/head. When carefully observing the interior of where the break occurred, there apprears to be the spinal column (color differentation) originating from the head that may have lead to the torso as well as part of the torso. Lastly, there appears to be some digits to a claw (encircled). If anybody want to contact me for additional details, please don't hesitate.

Hi all, just got into fossils as a hobby, please see my introduction message i just posted. As a MD i have some knowledge on bone structure and shape, ofcourse not perfect with animals. I’ve several fossils found by my dad over the last 20y and myself last months. Literally in the backyard. (<< Town in Holland aka the Netherlands, Europe>>) Crucial in this is area is used for sand mining. This has resulted in a large lake, with depts up to 100meter (200+ft i believe. The water is fed by an old river, called ‘oude ijssel’. I will split this in batches, to keep things orderly. thank you so much A: Egg? Was one piece but dropped it. B: vertebrae of what? Looks like bone to me, the verbebrea part. With clear distinction to what i believe is soft tisseu with skin ( 1 side)

Hi all, see pictures below, i’m jn doubt if this is an egg or just geological. found in The Netherlands Holland, in mining area. thank you

Hi, Could this be an egg fossil? I found walking on the beach and broke in the hope of finding an embryo. size: 4.5cm

Hello everyone, I am a Belgian student in biology, and I love paleontology. Last week, I was walking on a slag heap near my home in the town of Marcinelle, at the coal mine called "Bois du Cazier". My attention was mainly focused on fossils of carboniferous plants (sigilaria, cordaites, calamites, etc ...). But at one point, I picked up this pretty little pebble which seemed to me to be a fossilized archosaurian egg. The slag heaps do not really respect the order of the geological layers, so it is very difficult for me to pin a year on it. I wanted to ask you if it was possible to : - confirm / deny that it is a fossilized egg - date it approximately, in view of the material that composes it (in my opinion, it should belong to the Mesozoic area, because of the colour and the fact that it was necessary to logically pass through this layer when digging, before arriving at the carboniferous veins) - identify the order, maybe the family to which he may have belonged. Please excuse-me for my bad English, Thank you in advance for your answers !

Hello guys . I can i get some opinions on these two eggs They came from an old collection. So they say The first was labelled as a protoceratops 14.5cm The second one is labelled tabosaurus 17.5 cm Thanks

Hi guys, I have found an egg-like potential fossil, but I am totally amateur to the topic yet a very intuitive person, and as I was googling how to know if it really is a fossil or not I have stumbled upon this forum and thought to start a thread. Please help me find out if this is a fossil or just a pseudo one

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 is no eggshell. If you cannot see eggshell then you do not have an egg. If it looks the same shape as modern egg, such as from chicken then you do not have an egg. Concretions may have fragments breaking off and these will tend to be smooth on both sides. They tend to be dull earthy colors with a different composition in the center, as seen by a change in color. A different color in the center normally means you do not have an egg. Often circular bandings can be seen around exterior of concretions. Sizes of concretions range from just an inch, or a few millimeters, up to more than 10 ft (3 m). Egg sizes, along one side, range from just an inch or a few millimeters and top out at around 8 in (20 cm). If you find an oval or round shape, which is larger than 8 in (20 cm) along a side then it is probably not an egg. For more information on concretions: https://www.priweb.org/index.php/education/education-projects-programs/earth-101/concretions http://tumblehomelearning.com/geologists-find-largest-dinosaur-eggs-in-the-world-another-fraudulent-fossil/ https://en.wikipedia.org/wiki/Concretion In video form: https://www.youtube.com/watch?v=B5IoyLEwkMY Example of concretions, these three were incorrectly given an ID as “dinosaur eggs” however they are clearly not: From Tumblehome Learning, link above Pseudofossils: There are some pseudofossils, which can have a similar appearance to an actual egg, right down to seeming like there are bits of eggshell. This pseudofossil does look similar to an egg and even seems to have eggshell, however it is not an egg and is actually geologic. The surface ranges too much in texture and composition. Pic from Montana State University, taken by P. Germano Trace fossils: Many times, an actual trace fossil can be mistaken for an egg, common examples of this are pupa cases and cocoons. As one can see below, they do tend to have an egg-like shape and are yet another perfect example of why shape alone should not be used when trying to identify eggs. The three below are important trace fossils, just not eggs. Pic by Tony Martin, Ph.D. How to spot a real egg: The best and only true sign you have an actual egg is eggshell actually being present. Eggs come in many shapes from a semi-rounded, elongated oval to a perfect sphere and many others. Shape is not a good indicator of an egg. It is useful but only when combined with other details. Eggshell often has surface ornamentation that gives it a unique texture which can be seen by the naked eye or with a hand lens. There are many such ornamentations and they are used to help distinguish one egg type from another. On the surface look for little bumps, ridges with valleys, river channels, and similar textures. Individual fragments of eggshell are rather common in some geologic formations so be on the lookout for a larger grouping of eggshell. From University of California Museum of Paleontology Also read: http://www.thefossilforum.com/index.php?/topic/59654-dinosaur-eggs-lowell-carhart-guide/ Examples of real eggshell: Example of eggshell fragments: An eggshell fragment from Maiasaura, which is the oogenus Spheroolithus oosp. Pic by W. Freimuth. Examples of real eggs: A clutch of Troodon formosus eggs, which are the oospecies Prismatoolithus levis. Pic from Museum of the Rockies Do I have embryos inside this egg? Most likely no. Embryonic remains are extremely rare within eggs, and you add that with the rarity of eggs to start and it is a remote possibility. No fossilized yolks have been found and since they are soft tissue, it is near impossible for any to fossilize. I still think this is an egg! If you still think you have an actual egg, then please start a thread. Take close detailed pictures with something for scale such as a ruler and provide all the information you can about it--like where it was found. Good pictures will help greatly with a proper and correct ID. Below is an example of how to best photograph an egg or eggshell. There is clear lighting, a background which is clearly different than the eggshell in question and a scale bar. Lights can be as simple as a desk lamp; a scale bar can just be a ruler and the background can be very simple, in the example just a paper towel. Megaloolithus egg. Pic from Montana State University, taken by P. Germano If you would like to learn much more on eggs, here is the advanced egg guide which goes in depth. Also, see the advanced guide for sources.

During a trip to Egypt I found this potential fossil near the city of Aswan between the banks of the Nile River and Sahara Desert. I had thought it might have been a meteor and the sand fused around the meteor due to the Intense heat. But, I tested it with a magnet but there was absolutely no attraction. Therefore, I thought it might be a fossil given that I read about many fossils being discovered in the Sahara and the composition does appear to be any rock or stone that I've ever encountered. I assumed crocodile due to the spiky and bumpy texture, along with the historic prevalence of crocodiles in that region. What do you think this is? Thanks!

Hello Fossil Friends, Saw this in the news today so thought I’d share: ******************** World's smallest dinosaur egg fossil discovered in Japan Source Link A team of researchers said Tuesday it has discovered the world's smallest dinosaur egg fossil, measuring about 4.5 centimeters by 2 cm, in western Japan. The fossil of the egg, estimated to have weighed only about 10 grams more than 100 million years ago, was found in a stratum dating back to the Early Cretaceous period in Tamba, Hyogo Prefecture, according to the team. Supplied photo shows the world's smallest dinosaur egg fossil found in Tamba, Hyogo Prefecture, western Japan. (Photo courtesy of the University of Tsukuba and the Museum of Nature and Human Activities, Hyogo)(Kyodo) The researchers at the University of Tsukuba and the Museum of Nature and Human Activities, Hyogo, among others, who have analyzed the fossil, said it likely belonged to a non-avian small theropod. Skeletal remains of small dinosaurs are far less common than those of large dinosaurs, such as the Tyrannosaurus, which was also a theropod, and Kohei Tanaka of the University of Tsukuba, a member of the team, said he hopes the discovery will "help shed light on how small dinosaurs reproduced and nested." The team surveyed the stratum, which dates back 110 million years, between 2015 and 2019 and found four fossil eggs and over 1,300 scattered eggshell fragments. It has confirmed the findings, including the newly discovered one, which has been named Himeoolithus murakamii, can be categorized into four different types. The team said the discovery suggests that various small dinosaurs were nesting together in the area, known as one of the world's richest Lower Cretaceous fossil egg sites. Fossilized dinosaur eggs have been found elsewhere, including Spain and Mongolia, but many of them are 5 to 7 cm in length and weigh about 30 g. ******************** Thanks, Robert
