  1. The rather amazing discovery of an underground nest of about 50 fossilised eggs of an insect in the grasshopper-lineage (orthoptera) has been discovered in Michell, Oregon, at the John Day Fossil Beds National Monument. It's dated to the Oligocene-period, at 29 million years old, and is truly spectacular for its preservation. Insect eggs rarely preserve, and little information exists on the evolution of grasshopper-relatives. So finding a nest full of them is an amazing discovery! CNN-report here, original article here.

    Un identified specimen

    I have been stumped by a "rock" I found in my garden over 25 years ago. I have had a continuous need to know what it is purely for my own curiosity. It has "something" inside of it and during the years I've had suggestions of lizard eggs, man made object, etc. Ive obviously spent endless hours looking at it, and I think I've seen some kind of feathers entwined around the small round egg like masses encapsulated within the dark almost black in some light yet like sunrise in another. Its too large to float test fairly heavy makes me doubt amber but given the detail inside hard to think of alternatives.
  3. Dear all, It was difficult, very difficult to wait with posting, since I am very, very excited about this fossil find. However, I also wanted the Dutch magazine version to come out first. Well, it finally did this Tuesday, so here is some info in English, along with a couple of the figures. During a visit to the Piesberg near Osnabrück (Germany) in 2010, I found a stem fragment of Calamites decorated with strange, elongate-oval structures [Fig. 1]. While those features were unusual and quite remarkable, it proved difficult to find information about them and the fossil consequently went into my collection as unidentified. Last January, however, I stumbled upon a research paper that could shed light on the matter. The elongate-oval structures turn out to be one of the oldest-known examples of endophytic oviposition, i.e. egg-laying inside plant tissue, by insects. Fig. 1. The fossil specimen is atypical in several respects [Fig. 2]. The stem fragment doesn’t show the longitudinal ribs one usually sees on the internodes of Calamites. This is because we are looking at a preservation of the epidermis (outer layer of the stem), not at a cast of the central pith, which are more commonly found. Fossils of the epidermis (sometimes referred to as Calamophyllites) typically have internodes with a smooth surface (though it may be lightly striated or wrinkled), leaving few diagnostic features. Nonetheless, due to the presence of a characteristic nodal line with large, circular branch-scars [Fig. 2, shown on schematic in green], the fossil fragment can be identified as Calamites (subgenus Calamitina) with reasonable confidence. Below the nodal line with branch-scars, about eight elongate-oval structures can be observed [Fig. 1]. They are all orientated roughly parallel to the axis of the calamite stem and vary in length from 6 to 16 mm. A foreign nature with respect to the plant tissue is suggested by the gümbelite film in which the epidermis is preserved (gümbelite is a hydromuscovite and responsible for the well-known silver-grey colour of the fossils from the Piesberg). Note how this thin film of mineralization does not extend across several of the elongate-oval structures, which may indicate that the plant tissue there is either missing or damaged. Their exact origin, however, remained a mystery to me. Until recently. Fig. 2. While looking for information on some Carboniferous localities in France, I happened upon the research article ‘Earliest Evidence of Insect Endophytic Oviposition’ by Olivier Béthoux et al. (2004). The paper describes insect egg-laying structures, called oviposition-scars, found on two stem fragments of Calamites cistii from the Upper Carboniferous (Stephanian B/C) of Graissessac, Southern France. These scars are elongate-oval structures, orientated parallel to the axis of the stem, occurring on a preservation of calamite epidermis [see their Figures 1 and 2]. Careful preparation of three of these scars yielded small spherical cavities, which the researchers interpreted as imprints of the eggs themselves [see their Figure 2b]. The oviposition-scars from Graissessac vary in length from 5 to 38 mm and are surrounded by a thin film of organic material [see their Figure 2c]. Given the strong resemblance with the Piesberg-material, it didn’t take long to make the link with the mystery markings I found years earlier. Now, after confirmation by email from Olivier Béthoux and in person from Han van Konijnenburg-van Cittert, I can with reasonable certainty say that some sort of Carboniferous insect has laid its eggs in the calamite stem I found in the Piesberg quarry. This type of trace fossils is quite rare, so I am very happy I brought this one home. As a nice bonus this specimen comes from the Westphalian D, and is thus somewhat older (about 4 million years) than the published material from Graissessac (Stephanian BC), which is still cited as the oldest occurrence in recent literature. So you can really say this specimen from the Piesberg is one of the oldest examples around! Hope this was as fun and informative as this fossil has been for me, Tim
  4. Hello, A pair of curious eggs from China. 3 inches long, oval shaped. I thought they may be Segnosaur or Therizinosaur, but their eggs are rounder. A small species of hadrosaur, or maybe crocodile? The shell is very thin. The holes in them were caused by chisels during excavation, so they are damaged. But on the plus side, the damage does show how thin the shell is. Would any thoughts.
  5. So these possible eggs (rocks) were acquired from a chinese dealer back in the 70's and somehow came to a local shop to me where they knew nothing about authenticating them. The information I was told is they are from the Hunan Province in China. They were told to have been placed in the matrix base. Measurements: Egg 1- 4"x4" Egg 2- 4"x4" Egg 3- 4.5"x4.5" I even got them CT scanned which you can see the kinda blurry results but i'm curious... Are they real?... If so what kind?
  6. Hi I found a seller claiming to sell real dinosaur eggs. They are on online auction site and the seller is in South Korea. I have read through the forum and was encouraged to post pictures here to help get an answer. I appreciate the help in advance.
  7. Hello! I was hoping someone could help with identifying this fossil. It was found at an abandoned rental property in Copperas Cove, Texas about 15 years ago. I do not know where it was originally found. I hope these pictures are adequate. Thanks for any help!

    Eggs or Seeds

    Hi everybody first time here.I found a bag of polished stones none bigger than a quarter.I don't know where there from but I'm in Colorado so i take them home and put some of them under a microscope that connects to my computer and this is what i saw.The rocks themselves are dark red almost black in color about 1/2 inch long by 1/4 inch wide and corkscrew like shape.What are these how could these things get trapped inside the stone like this.if anybody has an idea of what these are let me know.thank's
  9. Hi all, I could not resist to get these 3 beautiful hadrosaur eggs. Those have been the last ones in my price range, and from a renowned local seller. Was wondering if anyone could give more insights. Here is what I have Possibly saurolophus 80 mio. year old, Cenomanian, Late Cretaceous Egg size 10.5 to 12cm (4 to 4.5"), about 8-9kg (18lbs) Xixia Basin, Henan province, China From an old collection Hoping no one tells me I bought some fakes .... (well, then I will return them ...). I am so curious. Getting them by tomorrow. Any comments from the experts here? Thanks a lot in advance. mr.rod
  10. Dear all, I am new in this forum! I want to check if the eggs on picture are real or not? Thanks for response already!! Merlijn

    What is this?

    Hi does anyone out there know if this is something worthwhile? I travel, mainly in the southwest looking for Agates and this is something I found on one of my trips. Unfortunately, I cannot remember exactly where. My best guess is I found it either in Idaho, Wyoming, New Mexico or Utah.
  12. The attached images are a microscopic images of a beetle in Burmese amber. As you can see its front legs look differently and rather strange. Also one of the images shows something that looks like an egg on its left leg and a small white something next to it. This small white thing might be a larvae. There is a fossil record of scale infect with eggs attached to their feet, but I was not able to find anything similar in regards to beetles. What do you think?

    Dinosaur egg?

    Greetings! Specimen found in Coshocton county, Ohio on a steep bank about 3 feet deep in grey clay. Trying to figure out not only ID, but also era, as time-frames don't seem to fit. It's a somewhat mysterious find from this geographic location. What this appears to me to be is a dinosaur egg, halfed, with a pretty well formed embryo exposed. There is definitely an obvious shell around the rounded end of the half egg. I'm basically a complete beginner in the world of fossils. Thanks for your time.

    My hadrosaur nest

    Hi people! Thanks to all the nice people here I wanted to share the pictures of some of my fossils. I wanted to start with what is currently my proudest and most expensive piece, my 3 egg hadrosaur nest from China. These are not crazy rare, also not museum quality but it was my first show piece that I bought and have been enjoying it everyday. Owning a piece of history, a nest of a creature that lived millions of years ago still makes me happy when I think about it. The eggshell and color on these is super nice compared to most I see at auctions. Let me know what you all think.
  16. hi folks, Im thinking of buying a cluster of Oviraptor from a seller who says he got these at a gem/fossil show over 10 years ago. He says he preps fossils and has extensive experience but has not finished prepping these particular eggs and won't get around to abrading them out of the matrix. I told him they are fake but he insists they are not, so I wanted to put it to the test here. thanks for your help.
  17. Any of these fossils?
  18. Things are getting pretty serious over in The Fossil Zone, so I cleared off a few books and replaced them with fossils. Who needs to read, anyway? Feel free to ask questions about particular pieces. Whole collection: The turtle skull is real, but the surrounding matrix has been stained by the preparator for better visibility. Some here might recognize the new claw that arrived broken in the mail There is a Vinctifer comptoni fish on the back right, along with a negative Grallator footprint, which I can't seem to find a good way to display. New additions here include a croc/turtle egg in-matrix, a Campo del Cielo meteorite, and a few various claws. There's also a piece of the Roman Colosseum, whose origin story I should not divulge. A complete Psittacosaurus foot joins the family. To its immediate left is a Triceratops frill spike. My best-prepared fossil here is the Ichthyosaur rib plate on the right – just incredible work. The little Knightia in the front reminds me every day I need to get a really good fish fossil soon. Amber Time! My favorite time. Rarer inclusions are a mushroom, pill pug, a gigantic damselfly, triple crane flies, a large millipede, caterpillar, a bloated tick/mite, moth with perfect wings, and a small lizard claw. More amber! S-shaped Centipede, multiple termites, a gecko tail, a big fuzzy bee (middle center), and my favorite... ...the back half of a lizard stuck to a leaf on the bottom right. Nice view of that killer centipede here as well! I'm gonna need a new shelf soon, but space is limited here in this tiny NYC studio apartment. Thanks for looking, friends!
  19. Hi, Newbie here. Wondering if these items are real. The pair are billed as oviraptor eggs. The other is billed as a hadrosaur egg. Thanks very much for sharing your thoughts! Best, Z!
  20. Hello everyone! My name is Weston and while I studied Geology at Whitman College, I never continued by degree. I am now getting a nursing degree and was stationed in Jordan, Montana for rural clinical. A contact of mine let me dig on land and I found all these fossils. Here is a link to my google drive photos. Please help me ID everything and anything you can. I am wondering if the things that look like eggs are actually eggs, as well as what the perfect sphere is. I am also wondering what dinosaur the bones most likely belonged to. I am confident there are coprolites right? I am emailing the Museum of the Rockies and Montana State University to get some help with ID, but I'm curious what you think! https://drive.google.com/drive/folders/1ygoAl7xSULYAMcD-F4i4MzZC31YqL3J0?usp=sharing

    A small fact.

    This little red oxide, buried subject, has officially beaten the smallest non-avian world record which is held by China. The world record holder is 1.77 inches, this subject held by a calibrated digital caliper is 1.49 inches. Two were actually found by each other. World records website says it is not currently entertaining submissions for Smallest Non-Avian Dinosaur Egg.
  22. Another curious little piece with multiple tiny scratches. Its a long shot, but could this be some type of predation? The shell is only 2 cm long though. Its the only shell piece among the bag with scratches on it like this.

    Eggs and Eggshell

    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.
  24. In this post I am going to show you a couple examples of fish related fossils that are found at Mazon Creek. Many of these are my finds and many are from my fossil mentor. The pics are zoomed up, I apologize for that, but I mounted my fossils (pairs) on white cardboard, so I do not want to pull them off and have to reattach them. First up is a lamprey - Mayomyzon pieckoensis. This lamprey was collected at Pit 11. Next up are a 3 examples of the Jawless fish- Gilpichthys greenei . These fish were found at Pit 11. Now I do not know if these names are still acceptable, but when I first started they were. These fish were found at Pit 11. Acanthodes marshi Acanthodes beecheri Here is a nice paleoniscoid that was found at Pit 11 and was ID’d by Dr. Dave Bardack, I believe the correct name is - Elonichthys peltigerus. This is a Rhabdoderma exiguum - Coelacanth. This fossil was found at Pit 4, in the area that I always called “Across From Pit 4”-(AFP4). Here is another nice Coelacanth- Rhabdoderma exiguum with a little coprolite. This piece was found at Pit 11 and I acquired it last year in a collection that I purchased. Here is another example- Now here is an odd one, it is called a Pipiscius zangerli. Many older collectors called it the “Push me- Pull me fish”. This second pic shows what should be the mouth. Now I know they are not classifying these as larval lungfish as they did when I first started, but I wanted to show a couple anyways. Here is Esconichthys apopyris. The first example shows multiple individuals. The next 3 are individuals. With this example you can see why collectors call them “ Ghosts”. This next piece was identified by Dr. Bardack as a fish head, but unknown species. This was found at Pit 11. This next piece I had brought with me to one of the Mazon Creek Open Houses at Northeastern and showed it to Dr. Bardack. He identified this as Acanthodian fish scales. This piece was found at Pit 11. Here are a few nice fish scales found at Pit 4 (AFP4). Here is a piece that I have identified as an Orthacanthus sp. tooth. This piece was found at Pit 4 (AFP4). Here are a couple Palaeoxyris. These pieces were found at Pit 4 (AFP4). Now these next pieces, all found at Pit 11, are described as either fish or amphibian eggs cases, either way they are very cool fossils. Mazonomaya helmichnus. This last piece is a spiral shark coprolite, not my best example, but one that I just came across. I also could not locate my Vertebrate Fossil of the Month find to post. Again these are some examples, I hope you enjoy them.

    Not sure what this is.

    Not sure what this is. I found it in the Texas hill country Blanco river. Its approximately 1 1/8 round. Can anybody help identify. Thank you.
