Hello everyone First, thanks for responding to my posts, and sorry they haven't been up to par. I, like most people do appreciate feedback because I learn something sometimes. I'm posting just a few of my finds from this weekend. This time I'm only asking,please, that if you are not 100 percent, don't comment please. I know what I've been finding, my wife seen it first hand today, and I seriously feel that this area hasn't had anything like this. Call me whatever you may wish! There are no other stones but headline stones at my property. A major amount of earth was removed to build up the levee on which our 50 acre lake depends on , if that says anything about the amount of dirt, clay. So, these were found about a mile from the Middle Fork, Salt Fork, and those 2 combined the Vermillion River in Rural Vermillion County. More to come!

I found this rock when walking near the Trinity River in Dallas, TX. It could have been brought in with gravel used to make a trail, since I found it by a trail. It's probably just a concretion, but the patterns are interesting! Anyone know what it is? Thanks!

Hi there. I am very new to this, but have always been fascinated by fossils. I have bought a few from a local dealer that I love, but while out looking at a collection of movie posters for my business, I ran across someone who also collected, rocks, minerals and fossils. The collector had passed away and his wife is selling some items. I would love to have dinosaur eggs. My grandson and I go to the museum all of the time and look at the fossils, and he loves the eggs, so if these are real, I would love to buy them for us. Can anyone help me with these? Thanks in advance! Michael

Can anyone tell me what this is?

This rock almost looks like a piece of styrofoam. Anyone know if it's a fossil or what it is? I had no luck in finding anything like it. That's a marble for comparison, really small.

Hello everyone! I have turned to all of my personal contacts and university professors and am unable to identify the rocks a wonderful lady gave to me and my children. She's collected rocks for more than 70 years and cut and polished stones for the jewelry she made. She said she didn't know what type of "rocks" she had given us were. I have several boxes of what to me are very different than anything I have ever seen. I don't want to destroy anything by accident. She told me that she used to take her finds to be looked at about 40 years ago but stopped after she brought in something that she had cut up already. Apparently it was a dinosaur tooth and the lapidary shop gave her a lot of grief, she never went back. I'm having difficulty uploading pictures so I'll start with the one I find most interesting. It weighs 27lbs and seems to have some type of metal inside. Thank you for taking the time to look. David

Hey guys, Saw this cluster of « raptor eggs » according to seller. What do you guys think? Is it real? Composite? Restored? I have no size,location or other pics... sorry. Kind regards.

This guy wants to sell these eggs to me but I don’t know if they are real or not someone please help. And if they are real what kind of eggs are they?

I found this fossil over a month ago. It appears to be a cluster of fossilized eggs? Or creatures?... I have had no luck even coming close to figuring out what this is. I found this in an area loaded with crinoids. Any help would be greatly appreciated.

Dear all, I'm a small collector from Geneva, I already have several fossils and I would like to acquire a Dino egg. I finally found one but I wanted to be sure that's a real one... Honestly, I'm not confident with all the fakes we find on the market... I have seen that your are experts in this domain and it would be very kind if you can help me to decide Thanks to all Cheers Franck

Evening all, Sorry to bore everyone with yet another egg post, however I stumbled across these "hadrosaur eggs" at the local antiques market. In the dark of the guy's stall they looked very real, but I'm having second thoughts as to its authenticity. Seller had no info bar that he got it off an old man who worked in SE Asia (red flag surely) and brought back a whole bunch of stuff. Anyway, thoughts and discussion would be appreciated!

I know there are a lot of tips on here to help identify eggs, but I want some opinions. See the photos purchased on ebay from china

A very large Moroccan centrum is being offered for sale. Seller identifies it as a Carcharodontosaurus. In my opinion this looks more like a Sauropod with that very large pleurocoel in the lateral view. Not sure what is going on with that purplish looking material if its been added. Spinosaurus tail, caudal vertebra being offered for sale no mention of any repairs. The centrum does look like its from a Spinosaurid but the processes look composited. You can see the typical Moroccan matrix mix between those processss and centrum. Seller is advertising this as a Carcharodontosaurus toe bone. Identifying isolated toe bones to a species in the Kem Kem is very difficult not much is published that describes them. Its a nice bone buy it as an indeterminate Theropod. Lots of eggs are showing up for sale. Most are fake....this is just a reminder of that, please post interests here before you buy. I still see some dealers offering Rugops teeth for sale from the Kem Kem. Just a reminder that this species is only described from the Echkar Fm of Niger. Most of the teeth offered are Abelisaurid but are indeterminate from the Kem Kem until something is published. For fun saw this 4 figure listing, seller describes it as a petrified baby dinosaur skull with teeth, skin and brain matter coming out of the side of its mouth looks like an alien head to me.

According to Google, all knowing and all wise..... "Eggshell is made almost entirely of calcium carbonate (CaCO3) crystals. It is a semipermeable membrane, which means that air and moisture can pass through its pores. The shell also has a thin outermost coating called the bloom or cuticle that helps keep out bacteria and dust." "Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3). It often has variable amounts of silica in it, as well as varying amounts of clay, silt, and sand. Limestone rocks fall under the category of sedimentary rocks that are made from mineral calcite." The question I pose is this, well there are several.......... If amphibian/reptile or bird species prefer to lay their eggs near water sources wouldn't it be a likely assumption that the permineralization of the eggshell would be reclaimed by the surrounding silicates while the inside turns to agate? Meanwhile, larger dinos layed their eggs in more forested inland areas and were not exposed to the same permineralization since there was less water exchange.? In the permineralization or petrification process, if an egg is in an undeveloped state would it agatize mostly transparent/opaque? What are, if any, the artifacts or features you guys look for beyond the obvious cracked shell on the exterior? I have looked but I have yet to find a good read that explains well what happens to eggs, soft tissue, and entire animals that are enveloped in volcanic mud flows. I just know there is a good read out there somewhere that gives a reasonable explanation to what happens to an animals remains as they fossilize. Maybe there isn't, I have yet to find the name of the guy that sat and watched it all happen. Does the blood cause the fe203 stain in a fossil? Do heavier minerals like Iron have a sedimentation characteristic during permineralization? Does displaced water content of the animal cause air pockets to form during permineralization? In nature, what causes living sources of silica to be in either crystalline or non-crystalline form? I have lot's more questions I'll do my best to google, but dang it's hard to find some of these answers. "Someone, out there on the net shouted. "Take a snarge class!"

An older article, but news to me. For the first time Trilobite eggs have been discovered in situ. http://www.geologypage.com/2017/02/trilobite-eggs-new-york.html

How an Amateur Collector Changed Paleontology Forever To those of The Fossil Forum, I wish to share with you the story of Maiasaura peeblesorum and Marion Brandvold, both good mothers. Maiasaura was discovered forty years ago in June of 1978; this is the month and year of the Maiasaura. Marion and her son, David Trexler, found fossils fascinating long before Jurassic Park popularized dinosaurs. They would often take a vehicle out and go prospecting in their backyard geologic formation known as the Two Medicine. One hot summer evening when walking back to the vehicle, Marion took a small detour and came upon some tiny fossilized bones. In 1937, the Trexlers had opened a rock and jewelry store, and over the years had created a successful jewelry manufacturing and wholesale business along with their ranching interest. However, Marion's heart was always with the land and the animals, and when her husband passed away, she opened a retail store for her merchandise rather than try to keep up with the wholesale business. That way, she still had time for the ranching and rock hunting that she loved. Marion and David had discovered a partial dinosaur in 1971, and they traveled the State of Montana to compare it to all the wonderful previous discoveries they had read about that had been made in Montana. To their surprise, the only dinosaur on display in the entire State was in a little museum in the basement of the high school in Ekalaka, Montana. It had been assembled by a couple of ranchers who had worked with paleontologists from elsewhere who had come to the State, collected, and left. Chagrined that nothing was left behind when professional work was done, they decided to start a small museum in the back of the family store. The goal was to display a dinosaur skeleton from their local area. After all, if ranchers from Ekalaka could do it, so could they. As far as professional training was concerned, Marion had to rely on her familiarity with the ecology of the modern world, as she had no formal education on the subject. However, a ranch foreman when she was young had taught her the art of tracking, and had shown her how each organism interacted with other organisms and its environment. So, when looking for fossil skeletons, Marion expected to see very young and very old animal pieces, but not much in-between. On the fateful evening mentioned previously, Marion, Dave, and Dave's wife, Laurie, were out collecting what they believed to be a fairly complete duckbilled dinosaur skeleton. It is a long, tedious job collecting all the bones present in a dinosaur, and they had uncovered 15 or so at that point. As tools were being put away, Marion went for a little walk, and when Dave and Laurie caught up with her, she was sitting on a small mound of dirt with a big smile on her face. She said, "look what I found!" She was holding several baby dinosaur vertebrae. Within a few minutes, they had found many more, and Dave had found a piece of a jaw with obviously duckbilled dinosaur teeth attached. However, the entire jaw section could be covered by a nickel! They had a baby dinosaur to go with their adult in the museum. Bill Clemens, a mammal paleontologist from Berkely, had stopped in Marion's shop on his way to dig on fossil fish with some colleagues, and was impressed with what had been done in creating a fossil museum without any formal training. At the fish site, he encouraged Jack Horner, then a fossil preparator at Princeton, and Jack's friend Bob Makela, a high school teacher from Rudyard, Montana, to stop at Marion's shop and see the displays. A few days later, Jack and Bob left the fish site and visited Marion's rock shop and museum. Jack introduced himself to Marion, and for the next few hours, they had a wonderful time going over the specimens Marion had on display. Jack then asked if she had anything else, and she showed him a couple of the vertebrae she had picked up from the baby site. Jack's interest was immediately piqued, and he asked if she had more. Marion directed him across the street to where Dave was reassembling the baby bones they had collected. Jack realized immediately that Marion and Dave had something they didn't understand. He asked, "do you know what you have here?", and Dave replied, "Obviously not, since you are so excited." The concept of babies and old animals dying and being preserved in the fossil record, it turned out, was only partially correct. While that cycle probably did occur, baby bones were generally not preserved in the fossil record. The bones Bob and Jack were staring at turned out to be the first baby dinosaur remains known from North America. Jack asked to be allowed to borrow the fossils in order to write them up in a formal publication. The bones were carefully wrapped and placed in a coffee can, and Jack transported them to Princeton. A visit to the site was also in order, and Marion and Dave took Jack and Bob out to the site. Dave also showed Jack a poorly preserved skull that Laurie had discovered, and Jack offered to try to remove it and clean it up for display in Marion's museum. However, after a few years and the specimen was recovered and prepared, it turned out to be the type skull for Maiasaura, and Laurie donated it to Museum of the Rockies, where Jack was working by then. Baby dinosaurs together in a nest past hatching showed a totally different picture of what dinosaurs were thought to be. Jack returned for many years, and eventually the Museum of the Rockies purchased the land where the babies were discovered. The area has become a mecca for paleontological research. The discovery of all this led to a massive shift in the view paleontologist and indeed science as a whole had for extinct animals and modern reptiles. A realization occurred that dinosaurs were truly living, breathing, majestic animals who cared for their young, much like the life we often see around us today. Hungry and thirsty, often looking for a mate, just trying to stay alive in an unforgiving world were the dinosaurs. Far from terrible lizards, they were much like animals and we humans are today. All this came from Marion’s tiny little find. It was her tiny find which led to a surge of interest and public attention. It was her tiny find which started Jack Horner’s career. It was her tiny find that indirectly caused Spielberg to help create Jurassic Park which in turn inspired many into paleontology and many more into other sciences. Those she indirectly inspired have contributed a near inconceivable amount to mankind through science. They range from medical researchers curing diseases, to those looking for extraterrestrial life, and all the way down to myself. A great many started their interest in the sciences with an early love of fossils and dinosaurs. A love Marion Branvold started and continues through her past contribution. Sadly, I never had the opportunity to meet her and she passed away in 2014, at the age of 102. Over the course of my short time in paleontology, I had the honor to stand where her tiny find was made. As the search for more discoveries continues I have been privileged to search with both Jack Horner and Dave Trexler. In the great quest for knowledge, she played her part well, now it is for us to carry on with the next act. What a massive contribution from an amateur and so tiny a find. As others ogle over the next major discovery, keep all this in mind and tell us more of your own tiny find. Eric P. Made with great assistance by David Trexler

I got an interesting offer for this clutch of hadrosaur and one raptor egg. Would be great to hear your opinions, as im still a newbie and dont wanna waste my money. If somebody cann give any indication of a fair price per PM would also be fine. Thanks

Offered through the link is one of our occasional interactions with someone who is either trolling TFF (great sport, apparently), or somewhat overwhelmed with runaway pareidolia. Our responses are also typical of how TFF works; presentations of the facts without any mockery or derision. We are here to help anyone seeking answers that are within our sphere of knowledge, but sometimes logic cannot prevail. >LINK<

So I was on a hunt for Patoskeys over on lake Huron and I came across this very odd find. It looks to have the exact qualities of an egg. I have been searching around to find others like it and have come up empty. Any help?

A Second Specimen of an adult oviraptorid Citipati osmolskae associated with a Nest of Eggs from Ukhaa Tolgod, Omnogov Aimag, Mongolia has been published http://digitallibrary.amnh.org/handle/2246/6858 The first published nest Second Specimen @-Andy- @HamptonsDoc

Seems there are quite a few threads asking if the specimen is an egg or not. So I have one in question. It this real?

I found this in the valley in a rock pile from an old rock avalanche in West Vail, CO. I've given it to my son's 4th grade class to figure out as well. Thanks for any leads.

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.
