    Please Help

    Hello I am new to the is hobby and need some help identifying this natural Formation. After a thorough inspection I can't help but wondering if this is some kind of crystalized skull/Head. Looking at the nose area I can see were the small holes go into the sinus area. Note the back looks to be severed and you can see the brain area, not to mention the deep set eye sockets you can see on one side the ear formation. I know this sounds bizarre but seeing is believing can anyone see what I'm seeing and please help with any thoughts. Thank you.
  3. This is one of my very rare and unusual artifacts I have quite an extensive collection this was believed to be a geode at first I'm no expert in fossil identification but I would like to say I know what this is and possibly has importance it was found in greater Southern California area has all of my artifacts and fossils tools which I'll post pictures of looking for advice and confirmation
  4. A 319-million-year-old brain has been discovered. It could be the oldest of its kind By Amarachi Orie, CNN, February 2, 2023 Scientists Discover 319-Million-Year-Old Fossilized Brain Amada Kooser, CNET, February 1, 2023 The paper is: Figueroa, R.T., Goodvin, D., Kolmann, M.A. et al.

  5. I recently found an extremely interesting paper published in the Journal of Comparative Neurology a few days ago by Professor Suzana Herculano-Houzel of Vanderbilt University about the neuron activity within the brain of the Dinosaur Tyrannosaurus rex (Western North America, Maastrichtian Cretaceous 68.0-66.0 million years ago). The study states there is evidence (based on the size of of the Cerebrum section of its brain and the hypothetical amount of neurons (of which for the study M=Millions of Neurons) present in the brain based on its size) Tyrannosaurus rex had between 2,207-3,289M telencephalic neurons in the Cerebrum section of its brain and was capable of problem solving and even forming unique cultures. Herculano‐Houzel, S. (2023). Theropod dinosaurs had primate‐like numbers of telencephalic neurons. Journal of Comparative Neurology. https://doi.org/10.1002/cne.25453 https://onlinelibrary.wiley.com/doi/epdf/10.1002/cne.25453 Usually I'm a bit skeptical when claims like this are made, but for Tyrannosaurus rex, I'm not surprised the least bit. It's been known for quite a while the brain to body ratio of Tyrannosaurus rex is larger than that of most other dinosaurs at 1.0 kilogram in weight (with only the Raptor dinosaur Troodon likely having a larger brain to body ratio among non-avian Theropod dinosaurs).

Indiana University Press, 19–33 https://anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar.20983 The recent study A large portion of its brain was devoted to smell, but I can easily see how the size of its brain could accommodate enough neuron activity for problem solving skills and even forming cultures. What do you guys think? What do you think of the study and what would Tyrannosaurus cultures have looked like?

    What is this thing?

    Found this in a stream in Hocking Hills, Ohio. Guessing it’s some coral or something…??
  7. I found this brain shaped object on the south cost of England. It’s very heavy. It is not magnetic.
  8. I say, Mostly all rocks use to be something unless you are right onto of some geological formation. I took a picture under a electronic microscope you can clearly make out the synapse. Only something that has a biological brain will have this

    Corals

    I was out hunting the Peace River yesterday, and then went to my local fossil club meeting, last of the season doing a swap & sell, show and tell session. There were some impressive finds this season. I did not get a lot of photos but the TFF member sitting at my table had these: Matched pair of Mastodon 8 humpers. That's a great find. I always sign up for the Club Raffle, which has a lot of items donated by club members and I won. Went to the fossil table and selected this ziplock bag of coral fragments: I recognize that Rose Coral (Manicina areolata) and what looks like Brian corals on the right side. As soon as I saw those splotches on the bottom coral, I knew I had questions to ask on TFF today. That is the ID question. What is the coral? and what are the possibilities for that encrustation on the underside?
  10. I was looking at some of my collection yesterday and dextrose take pictures of my better mammal brain endocasts from the White River Badlands of South Dakota. The first piece is exposed on a partial skull of an Oreodont. This next piece is my favorite and I believe it is from an Oreodont. These other pieces I can only guess, but I would also think Oreodont. This small one appears to be from a rabbit. This last one was ID’d as coming from a Hesperocyon, but cannot confirm that.

    Petrified brain coral?

    I found this in my Seattle area yard, near the dead stump of a small maple. After washing and bleaching the septums appear filled with sand and shell bits. There is also something growing throughout it like a veinous system—likely plant? It is heavy. There are striated and mineralized layers. There is a ventricle feature and a faceted stem—it’s disturbingly brain-like. I feel honored to have finally guessed my way through your captcha (respect!)~~hoping someone can identify this oddity. Best guesses so far are coral or fungus, but I’ve not found any examples sporting this stem canal...
  12. Hello, I saw this online. Just curious if it actually is what the label states: Oreodont Braincast / Badlands of South Dakota / Oligocene Period. Thank you for any and all help.

    Fossil or mineral

    Cheboygan Michigan they look like brains, I find them from baseball to basketball sizes. I broke one up with a sledge hammer, the center gets more dense. The out side seems to house shells?

    Triceratops skull and brain case

    From the album: Dinosaurs & flying reptiles

    Another view showing an area of what I do not know. I'm guessing it involves nerve fibers/channels.

    Triceratops skull and brain case

    From the album: Dinosaurs & flying reptiles

    Another view showing more channels/cross sections of blood flow(the small solid dark gray areas), and nerve channels. I'm not entirely sure what the large dark areas are, although I believe it to be related to blood flow as well.

    Triceratops skull with brain case

    From the album: Dinosaurs & flying reptiles

    Another view showing the spongy internal bone growth

    Triceratops skull and brain case

    From the album: Dinosaurs & flying reptiles

    2 pieces of a triceratops skull with brain case impression. Blood vessels, veins, and arteries visible, as well as nerve channels. I have to contact in order to get the fossil information again.
