Fossil preparation repair restoration dinosaur albertosaurus tooth
Dinobot posted a topic in Fossil Preparation
Hi there I recently purchased a Albertasaurus tooth. A portion is in a matrix and there are some broken off pieces. This would be my first attempt a putting a fossil back together. If you could provide any input on 1. if it would devalue it by doing it, 2. how I should do it, 3. and what tools or glue or putty I should use. If you could dumb down the language for me that would be appreciated, like I said this is my first time!

I need help identifying these fossils found in central Texas. Specifically, the conical shaped one on matrix in front of the sphere, and the two immediately to the right of the sphere. The conical shaped fossil looks as if it might have spiral structure, but may simply be slanted segments. The two shells on the right are the same as each other, but one is face-up and the other is face-down.

Hello all! Just looking to get some opinions on what I have found. This piece was found in southern New Jersey, almost as far south as you can go, in the Cape May County Area. It was uncovered in some dirt after digging for a new septic system. It’s about an inch and half long and very thin. Any chance that what I found could be a fossil of some sort?

Hi, longtime lurker first time poster here. I was wondering if you guys can help me ID this concretion my family found years ago near Calvert. I believe it might be a trace fossil of some kind, possibly a burrow or tunnel. I have found similar types at Westmoreland State Park. I can upload pictures from different angles if needed. Any suggestions of what it could be?

Hello all, I am new to the fossil forum ( obviously). A little bit about myself: I have formal training and education in vertebrate Paleontology. I double majored in Geology/ Zoology in college and continued to get a Phd in vertebrate Paleontology. I was the adjunct professor of dinosaur Biology at the local community college until the shutdown. My specialization is theropod dinosaurs, but I have experience with a variety of fossil animals. My area of least experience is probably fossil mammals, so you will likely see me posting some pics of bones on here for second opinions. When it comes to dinosaurs I've worked with basically everything. If you can think of a dinosaur, I've probably dug up something like it. I've also worked on mapping sauropod and pterosaur tracks of the Morrison fm. Since moving to Oregon ( United States) I have had difficulty finding work in my fields of study, so I decided to start trying to survive on my own. I am a bit out of practice ( 5 years of not practicing paleo), but have recently started getting back into the swing of things. I have begun research into reconstructing paleo climate of the oregon coast using bivalve shells, specifically pecten, as a biological index for measuring chemical changes in sea water. I have mainly been looking into the newportian stage of the Astoria fm ( 15-18 million year old rocks). This represents the mid- Miocene. I have collected several vertebrate fossils on the coast, most of which haven't been prepped or I'd yet, but I know for a fact that I have a couple of whale vertebrae ( one juvenile, one mature) as well as a large juvenile pinniped/ walrus, a deep sea fish vert cross section ( complete with diploe), a section of shoulder blade and rib from (?), a vertebra from something like an otter, and a bone I have yet to make any decisions on. I look forward to getting to know all of you, and share knowledge.

Hello, I have been finding all sorts of neat rocks and marine fossils in the desert outside of Yuma, Arizona where the Colorado river had once flowed into a large ocean. There seems to be some sort of worm creature fossilized in this stone? I would appreciate an ID on the specimen, or speculation as to what it is? Thank you.

I was wondering if this could possibly be a coprolite? Or just a rock that has formed this way over time. Found in the Rocky Mountains of Wyoming. Thanks for your input!

Hi everybody Recently I was examinating limestones with gastropods (turritelids) and I found this. I think it's a fish tooth, but I'm not sure. What do you think? From lower cretaceous (Lower-Upper Aptiense ) Sea sediments. P.s. Sorry about the quality. It's really tiny. P.s.2. How are you all? I hope everything is okay with this quarantine.

Hi, please stare at this trilobite that I just snagged and tell me if you would agree with me that it's real, or if you think it's fake. If the latter, I would appreciate your reasons. Edit: pictures posted properly. Also I ask because I'm still very new at collecting.

This belongs to a friend of mine. Never seen anything like it myself, so I have no information for now. He thought it might be Halysite (chain coral).

Hi everyone, i'm doing the thesis of master degree in paleontology and I'm studying a new internal lagoon near a carbonate platform. At this moment I can't go to university because we are in quarantine and therefore I can't consult with the professors and can't use various methods. So I ask you for help. Can anyone identify these fish, even just the family they belong to? They are all from the Turonian and they come from a kind of Plattenkalk and represent the only vertebrates found. Thank you

Hello! I’m not sure if this is going to be a “oh he had that set” type of post but I hope not haha! long story short about 14 years ago (when I was 12) I got a rock collection from a yard sale with my mother and inside were some cool fossils which I added rocks next to throughout. I forgot I had this for about 12 years. Each fossil has an identifying yellow card - I think I found the distributor of this from way back when but I’m unsure. I don’t want to sell anything as I kind of treasure my childhood but I’d love to know if this stuff is actually real because that would be pretty awesome lol! Apparently I have a dinosaur bone? I’d like to know! thank you for taking the time to look I also understand it’s impossible to verify without tests and stuff but, I’m hoping for some optimistic responses!

Good morning! I was hiking along a park path when I inspected a large boulder and found these two fossils, the first of which is similar to modern day scallop. I didn't have anything to measure with -my apologies, but it was approximately 1 1/4" in height and 1" across. the other object has some faint lines/rays emanating from ~9:00 to 2:00, but not sure it is overlying the underside of another shell, or is part of the fossil. This one is approximately 1 1/2" x 3/4 " Any thoughts and suggestions on i.d.s welcome and encouraged!..... not sure I could remove the scallop intact but thoughts on how to do that as well? Bone

Hi there i continue to maintain my very very amateur status but I've been trying to read the different threads on here regarding spinosaurus jaw and what I gathered so far is pitting is reflective of croc jaw and if it only has a single socket or also makes it difficult to determine if its spino or croc. I found this one on our favorite auction site and wanted to get your opinion

I found this while rock hunting in the Stanislaus river, Modesto, CA. If anyone can help identify it I would be very grateful. Thank you.

Hi all, we found way we hope is a fossil today in Lyme Regis. Does anyone know what we have found, if and how we can remove the outer layer to reveal what is hopefully a lovely fossil inside. best wishes Tim

Howdy! I've been trying to properly ID some of my toothy finds from the Peace River and Venice Florida. Please let me know if I have misidentified any. Also, including a few that I am not sure about. Any help is appreciated! Pretty sure the are Megalodon, but not 100 percent. 1. 2 inches top to bottom 2 One inch top to bottom . 3 One inch, obviously. . Snaggletooth Hemipristis: 4. One Inch 5. One inch 6 Just over one inch obviously , Carcharinus (Bull Sharks? Whaler Sharks? Dusky Sharks?) Not sure what species.. Would like to narrow it down, but not sure about that. 7. 3/4 Inch 8. 9. One Inch 10 11. 3/4 inch . Lemon Shark - I am pretty positive on the Lemon ID I just wanted to show this precious teeny tiny tooth: It think that is a salt crystal growing on the side! 12. Tiger Shark 13 3/4 Inch 14 3/4 inch Unknown: 15. A worn Carcharinus? 16. 1/4 inch
