I have been using this website to help educate myself and identify theses teeth. I believe all teeth on the right of the penny are the sameness; Lemon Shark. I also believe that all the teeth are the same to the left of the penny. My initial thought was Copper Shark. After going through this website I was thinking Thresher Shark. Any help or confirmation with thes would be much appreciated. This is the link https://www.floridamuseum.ufl.edu/discover-fish/sharks/fossil/shark-tooth-id-guide/#q23

If I had to guess on some of these the top 2 on the left are lemon, far right is a hemi, and bottom left is a hammerhead not sure about that or any of the others any help would be much appreciated

I'm currently trying to identify the genus of some of my ammonite fossils? I believe the two small specimens are Hildoceras and Gonaitite and the large specimen is of the genus Cleoniceras. But I do not know for sure. Can someone confirm or correct me on this?

My friend gave me this earlier today and I have absolutely no idea what it is. Can someone help me out?

Hi. Me again. I feel like I post something everyday asking for help. I really have learned so much from everyone here the past month. So a big thank you. So I believe based on research and past post that the first group of teeth are bull shark because the location of the nutrient pore on the lingual side is below the bulge in the root. The second picture I believe is also carcharhinus but not bull because instead of a nutrient pore on the lingual side there is a transverse groove. So that leads me to the question what type of carcharhinus has a transverse groove? I hope on the right path in my thinking. Boy I hope so or this post will be embarrassing. Haha. Thank as always for any feedback! Mark

Hi. I believe this is hemi. My confidence on identifying is not the greatest. Getting there. Learning more every day. Any feedback is much appreciated. Thanks Mark

I just picked up this small fossilized crab, I am told it is from the Oligocene period and was found in the Lincoln Formation SW Washington. My research leads me to believe it is a Pulalius Vulgaris. If anyone can confirm its identity I'd be grateful. There are also these cylindrical cross sections seen in the second picture. Are these fragments of limbs, buried under the matrix or something else?

Hey guys. I am a new member and currently an 18-year-old freshman college student. I am currently going through basics but as a kid, I loved dinosaurs and prehistoric creatures. I recently have thought about changing my major from biology to paleontology. I am a fossil collector and hope to collect hundreds of examples of prehistoric life. As I said I'm a fossil collector but a novice at it. I know relatively what a given organism is but I want to know, if possible, the species. If they are completely unidentifiable, no worries. I might add that all of these fossils did not have locations of where they were found except the starfish which was found in Morocco. I'm making a log of all my fossils and want to know the genus of each individual one. I have linked a google drive folder with all the images of the ones I would like identified if possible. Feel free to message me with any questions or just to get to know me. I'm open to making friends with fellow lovers of life. Thanks. https://drive.google.com/drive/folders/1m0QB8pmy-snZYujwb6Fy06flKsRxQK3E

Hi are these bull shark or dusky shark teeth. How in the world to you tell the difference? Thanks for any feedback!

I believe these are all Hemi’s not confident about the top row far right one. Any feedback would be much appreciated. Thanks!!

Hello all, Thanks for letting me post my inquiry. I was wondering if any of you could give your input on a large "rock" that I found in my yard. I live in Menlo Park, California which is about a mile north of Stanford University in the San Francisco Bay Area. Please excuse my ignorance when it comes to the fossil world. I have zero knowledge in this area, but i must say that after only a few days of investigating websites and forums I find it quite fascinating. And also a massive black hole lol.. I have spent all of my free time looking into the topic the past couple days. so many hours!! (not complaining, its been awesome!) Anyways I will attach pictures below. The only reason I think it is a coprolite is because of the many other "rocks" that I have also found on the property, about 20 or so, that fit many pictures I have seen on the internet. But this one doesn't really look like any of the others and is quite large, at least double the size of the others. At first glance I thought it to be chunk of a wood round, as i have found petrified wood on the property, at least what I believe to be petrified wood. When I picked it up I noticed that it was very heavy, probably 30+ pounds, so definitely not fresh wood as this is way to dense to be so. Gave it a knock and its rock hard. On most of the outside there are small flakes of something shiny, some metallicy and some more clear, some faintly yellow/green.. I dont know if its crystal or something else but they seem to be thin pieces of something, some layered on top of each other. What struck me at first was the green that was viewable in some spots. This is the reason I picked it up in the first place to investigate further. The one green spot is mostly white now actually. After I noticed the green I had a piece of sand paper handy and I gave a quick rub on the white part to see if more green was under it and there was. However a day later the green has gone back to white. Not sure if thats from oxygen exposure or possibly the abrasiveness of the sandpaper causing scratches which turned white with time. The outraged just looks really really old is the best way I can sum it up. There was a small section that was slightly sticks out and cracked a bit so I knew it would come of easy. Gave it a wack with a chisel and it popped off. I will attach pictures of that as well. I have scraped at a couple sections, trying to see what was inside, and it seems to be green and brown in most. Parts have a serpentine look to them, which was my second guess after wood. But the rock just seemed to be to "living" if that makes sense. There are vertical and horizontal cracks throughout some with some sort of white lining in them. I really want to crack it open as I think it might be quite beautiful, based on the weight and density. Anyways I could go on but I will just post some photos and hopefully you can help me out a bit, because at the end of the day I really have no clue and don't pretend to. Also, another question I have.. Is it possible to have undigested chances of reptiles/fish/eggs inside a coprolite? not this one, but many of the other pieces I have found seem to have pretty clear inclusions of things like turtles and other things. I could be crazy also, but some of the inclusions seem to have something like skin still on them, which after research i noticed could be just lichen, but its strange that the lichen would just be on the inclusion and be a believable color as well. There also appear to be many many bite marks or teeth marks on them. My understanding is that my part of California would have been under water, and wouldn't be possible for dinosaurs to leave the coprolite. And based off the inclusions in the other rocks, it would seem to be a water beast anyways, or possible a large bird, ore maybe just something that lived by water. but not sure because like I said my area was below the sea back then. It just seems so large for it to be from a sea creature and I would have thought if something pooped in the ocean. would not most of it disperse and break apart in the water before it sunk and was covered up? Again, i have no clue haha Let me know if you want to see some of the inlusion pieces or more1 photos of this one. Photo #4 shows what i thought to be skin on this one, but other pieces are more clear. But again I have no idea Thanks for your time and I hope that a least one of you can help me out a bit! Have a great day!

A find from earlier this year. Creek bed on the surface here in West KY, (Graves County). Got it because it was different. (I started truly hunting fossils for my son who loves dinosaurs more than anything.) I had no idea as to what it might be but the shape kept me thinking I'd seen it before. I happened to be looking at Mosasaurs one day & happened to see a Moroccan peg-toothed specimen. Researched if they might have lived in the sea here. Saw a paper about Globidens which had some illustrations, then found out about Alabamaensis. Thought I had a jaw fragment minus teeth of one of those. Now I highly doubt it, but you are the people to ask! Who is it, JohnJ who has the quote about convincing yourself to believe anything?

Hi All! New here... Wondering if anyone can identify these 2 fossils I found... or maybe they're not fossils? Found near Calvert Cliffs Md. Thanks, Ed C.

Other things I found today at Big Brook besides the bones I posted

Does anyone know what type of bone this?

Hi. Went to big brook today in nj. First time I ever picked up something that was not a sharks tooth. Found some good things but have no idea. Any thought would be awesome!! Mark

One of my finds from yesterday. Found it on the surface in a creek bed here in W KY. (That is 99% of my finds!) Apologies for not knowing the geology & time frame. Not quite sure how to go about figuring that out yet. Could this be a sponge or coral? It's about 12 cm long, 9 wide at the widest, & heavy, probably 2 lbs. at least.

Back again! My fossil hunting partner and I have found a killer spot here in North Florida. We've found a collection of things thus far (left to right)-- partial meg (would have been a pretty decent size), juvenile meg, dugong rib (with feeding damage, found next to juv meg), a shark tooth I can't identify (serrated), and an unidentifiable bone. We've also found turtle shell, lemon shark teeth, whale vert and lots of bone! Any ideas what the ID of smaller tooth and bone are?

Hi. Found these this summer on the beach in NJ. Have no idea what they are. Any help will be much appreciated! Mark

Hi. I posted these two teeth yesterday but the picture was horrible. Any thoughts on what they are. I think one is a Mako. Any feedback is much appreciated. Thanks. Mark

Hi. First I would like to apologize in advance if I am stepping out of bounds with this ID request. Feel free to tell me if this is not appropriate. I am just really getting into this and trying to separate my collection of 800+ teeth by species. I think I have handle on the different types of tiger shark teeth but now I need help with these so I can get pointed in the right direction. Thank you so much in advance for any feedback and please tell me to go pound sand if this is a crazy pic. Mark

Hi. These are a little worn down. They are all about an inch long. Any feedback is much appreciated. Thanks! Mark

Was working in garden pulling weeds when this came up from the ground. Has a smooth back and the front has texture and is very lightweight compared to a rock it's size. Is this a tooth or bone or just junk? Any help will be appreciated.

Hi! I found these fossils on my day at les vaches noires in Normandie, France today and i could really use your help identifying them. Thanks in advance!
