    Mushroom shape?

    Picked up at a yard sale in Nor Cal. It has the appearance of base of horn or a mushroom. What do you think?
  2. @lizardite I thought that we should move this interesting reminiscing about northern California geology and paleontology out of the member introduction section so that more people might see it. Continuation from: http://www.thefossilforum.com/index.php?/topic/122442-greetings-from-carlsbad/&tab=comments#comment-1339414 Here is one of my interesting finds from the Bay Area. The most recent palm fossil found in Northern California. I could not convince UC Berkeley to keep it.
  3. Does anyone have any ideas on what transformations an organism undergoes as it becomes an inclusion? Why do they often become translucent or transparent? Why do they often turn black/brown? Do they polymerize? How do some inclusions retain a lifelike or unaltered appearance? Why do exposed sections of inclusions have a crystalline appearance? I'm surprised that I can't find any meaningful answers to these questions.
  4. As the title states, lets hear the best puns you've got! I think we all need a bit of laughter these days especially, so lets raise a glass (and hopefully a smile!), and share our best (rock)cracking puns! Puns and jokes accepted from geology and palaeontology! Lets start off with one per person, and to get us all started, something I thought of today! What's a geologist's favourite drink? Gin and tec-tonic!

    Is this just geology?

    I'm assuming this is just geology, but I wanted to make sure. I found it in a seasonal creek bed in south central Missouri, USA. It measures 3 inches by two inches and is a little whiter than the image indicates. Any help is appreciated. Doug
  6. I'm just gonna start dumping pictures here of cool stuff I've found. All of this stuff is from the outdoors; I mean sure, I have some cool store-bought stuff like snowflake obsidian but that's not what I'm interested in sharing here. Some of this stuff I have in the other thread I started, but I'll post other stuff too. Nice lil' Hag Stone "The Brain" uhm....."Concretions" (Still working on an ID on these) Really old Coal (I think the term is anthracite?) Glassy rock I found, not sure what it is exactly. Garnet-y bits.
  7. Please find attached pictures of an oddly shaped and structured object. It was found while removing a deep rooted tree. This was in Royse City in Hunt County. After having no luck identifying it, somebody suggested this forum for guidance. Thank you for your review. Joe
  8. What kind of layers are these in East Tennessee very fine paper thin black stone, lots of natural right angles and mixed egg shapes and ovals seem to be found in them. 20 feet Above these layers are thicker gray limestone with corals and crinoids Does anyone know the story of these layers
  9. hi, i am new to this forum. I bought these 2 trilobite fossils from a shop in los angeles. It was an antiques shop. I am just curious if someone can tell me if these ar genuine or fakes? thank you

    Google Timelapse

    It let you view any place on the earth how it has changed in 37 years via time-lapse animation. One thing I particular like about is the soil erosion. https://earthengine.google.com/timelapse/

    Fossil Shell or Odd Mineral?

    Are these fossil shells with odd mineralization or a mineral of some sort?
  12. Here is my list of favorite items for geology and paleontology enthusiasts for 2020. Please feel free to add you own selections; give a specific model that you have used or researched. Estwing Geology Hammer, Estwing E6-24PC - Larger head and weight to partly replace small crack hammer and make it easier to hit your target. One piece construction can last a long time. Write in the Rain waterproof notebook, No. 135 - Take notes on your fossil localities. Fits in pocket. Select a bright color and get a good pen or a mechanical pencil with a large diameter lead. Fischer Bullet Space Pen - Most reliable write-anywhere small pen. Belomo 10X hand lens - Great lens for the price. Makes a great macro lens for smart phone cameras. Best balance between magnification and field of view. Get a bright-colored lanyard to help save it from loss.

    It's definitely a..thing?

    Look guys I have a... well its definitely a something? Is it a plant, the top of a crinoid, a broken tooth, a really tiny volcano??? No idea. And as a bonus I have no idea where it came from either. It was given to me ages when I was a kid. So if you've got any ideas on what the heck it might be, I'd love to hear 'em! Thanks!
  14. Hey everyone. I thought I'd share some of the things I found on my last fossil hunt. So.. Many.. Fossils! One might even say that there were a plethora of fossils. If I could, I would've taken them all with me, but sadly my backpack can only carry so many rocks. I was literally examining each rock I had, trying to decide which to carry back and which to leave behind and how many I could fit in my pants pockets before they started to fall down. Eventually I decided to just stop looking for fossils and hike back to the jeep. This lasted all of 3 seconds before I found another a beautiful byrozoan and was trying to figure out how to fit it in my pack. The byrozoan and the sponge below are my favorites since i don't see many of them and the brachipod in the matrix just looks cool. lol Its fascinating to look at these fossils and think about how Arizona used to be completely underwater long, long ago.

    What do you think?

    Hey guys, I'm back with another ID question. The fossil I'm trying to identify is in the 1st picture. I think that what I have is a fossilized brachiopod WITHOUT the shell. What do you guys think? It's the same general shape, but the color and textures of this fossil look different than others I've found in the area. The symmetrical textured part in between the two humps, I've never seen before. Pictures 1,2, and 5 show the fossil in question and pictures 3 and 4 show examples of other brachiopods that I've found. The last picture is an example of a brachiopod that was broken in half, exposing the animal inside. (when I uploaded the post the pictures got out of order) So anyways, that's what I think I have but I'd really appreciate your thoughts on this. Ya'll have a lot more experience with these thing than I do so I welcome your opinions. Thanks!
  16. I have a fossil hunting friend, who keeps very little of what he finds. Anything that has serious issues goes back to the fossil gods or into the bone garden at home. To make it into his collection, it must be exceptionally good. I am not like that... I keep almost everything... to analyze and toss later maybe, but initially keep it. He keeps very few fossils, which has its advantages. We sort of have a deal... anything he does not want (in certain categories) he saves for me.. I do what I can to repay the kindness. One of those categories is whale: He gave me this one last week It is a 4.25 inch Florida whale tooth, likely Kogiopsis. My question relates to the composition. The species seems to have no enamel, so originally this was dentine, surrounded by cementum. It is a land find from a construction site in Florida. I have similar teeth with this composition from the Bone Valley phosphate mines. To show a different Kogiopsis tooth, found in the Peace River, with a different composition: It is what I call "hard" composition... So the questions: 1) Is this composition unique to Florida? Do other TFF members who find whole/broken whale teeth (or any other fossil) have this type of composition in their fossil collections? 2) What is the composition and the process that creates it? Thanks, Just driven by curiosity. Jack

    Is this a bone?

    Is this a bone, and if so what kind of bone is it and maybe what kind if animal could it have came from? For context it was given to my grandfather by his brother in Arkansas a long time ago. Any help would be greatly appreciated
  18. I might be wrong, but I believe that this rock is sandstone (if it isn’t please correct me) and that the spots in it are feldspar. I was wondering why there is such an odd placement of the feldspar(if it is feldspar) and it made me wonder if there could be fossils in it. I was planning on putting it in a rock tumbler to see if it would turn out good, but if there are fossils in it, wouldn’t it be better to work on the rock and uncover them instead of just polishing the whole rock. If you think that there could be fossils contained in it, what could it possibly be? If not, no worries I’ll probably just toss it in my rock tumbler and see what happens to it lol. (Btw it was found on cannon beach in Oregon about a year ago for context)

    Geological?

    Hello together, Something I quite often see in the ID-section are pseudofossils commented as "geological/rock". I dont want to be nitpicking, probably it´s just short for "purely geological". Simply "geological" doesn´t seem opposed to fossil, in my understanding fossils do happen at the interesection between geology and biology. So "no biologic structure"=no fossil (except chemical fossils) , but "geological" seems to apply to all the specimens (if they are not molten plastic, recent bone, or something else entirely. ) English is not my native tongue as you may have noticed, but in my understanding fossils are also rocks, at least some kinds, for example steinkern preservation, (rocks with) impressions... So it may be confusing especially for the newbies that often ask about pseudofossils if "geology" stands as the opposite of fossil. What do you think? Best Regards, J
  20. Well, in my research to find a fossiliferous bed near me I have been struggling with the geology, and spending days driving around observing, taking notes and pics. Well, I just found a published paper from one of the original paleontologists. In it, he lists the location of each outcrop, but this leads to more confusion. When I track the T,R,S locations listed, there is nothing there. Every promising site I found while scouting is clearly visible on satellite mapping. When I look up the listed spots, I find NOTHING. It's just plowed farmland. I find zero evidence of buttes, mesas, draws, cuts or anything that could be an exposure of the formation. I've obviously got to do some more "boots on the ground" stuff, but I'm not feeling hopeful for the listed sites. Maybe I'll start by investigating any outcrops closest to the listed locations.

    Where to go in New Mexico

    Greetings!!! I'm planning a trip to New Mexico this summer. I would welcome any information besides the basic tourist stuff. I'll be in the northern Farmington area for a week. Can't wait!!! Thanks in advance for any insight. Bruce (WATERLINE)
  22. Greetings kind people, I'm so sorry if this is such a noob question. But I've searched and searched but I couldn't find answers to these on internet. (kindly correct me because I feel I maybe wrong): Smithsonian website said licking dinosaur fossil helps in identifying between a rock or a fossil... But isn't fossil a rock in itself? Fossils are made because minerals get replaced and it's not possible for bone to remain in its original state for millions of years. So, it's not the original material anymore.. so licking a fossil should equal to licking a rock? In that case, licking should not work?
  23. Nothing to say about it other than the pic. I found it as is and did nothing except cleaning with water. So pretty. any ideas what it might be?
  24. I am assuming that this feature is just geology, but I would like a second opinion on this if possible. My eyes do wonders at seeing what I want to see instead of what is actually there. Thank you. This was found in Douglas County, Missouri, USA in the Roubidoux Formation. The feature in question measures 84x31mm. The host rock is 20x12.5cm. It was found near a seasonal creek bed where gastropods, rugose coral and crinoids have been found. Numerous trace fossils have been found in the area also. Thank you for your time and help.
  25. Efforts are ramping up to have this region added to the Canadian geopark family. The UNESCO folks just finished their visit. Let's wish them all the success! Possible Nova Scotian United Nations geopark a hidden gem - Keenan
