  1. Past hour
  2. Possible Horse Tooth

    It's most likely a lower premolar four (p4) from a bison which would make it Pleistocene to Recent. The gross size of these teeth is variable just like the size of the living animals.
  3. Bone fossil?

    Ken, Thank you for the great information! Very interesting. I bet you are right on about displaced fossils brought up with fill dirt. There is a pond behind the houses in the loop of our subdivision and our house sits considerably above the street. Likely built up from the hole and brought fossil along. Thanks again!
  4. Thank you for your analysis. These are pictures provided by the seller, I do not own the specimen currently. Now that you've got me thinking about biology, do you know if the grooves interpreted to be traces of blood vessels? If so, which side of the frill would one expect to find these vessels (e.g. anterior or posterior)? Thank you @LordTrilobite and @Troodon for your input as well!
  5. Syracuse New York area?

    The site is accessible.
  6. Lines on therapod tooth

    Does anyone know what these lines are on this tooth from the Lourhina, Portugal and do they help in ID?
  7. Southern Lake Michigan Hunting

    In the upper right corner that is a fossil of shell fragments? Might be something else but fragments nonetheless. Upper left corner specimen -- not enough if it is visible to even begin to speculate what it may be. The rest is a very nice batch of septarian concretions, with the exception of the rugose coral of course.
  8. Help Identifying Bones From Morocco

    Hello. I was wanted help identifying some bones in matrix. The seller claims they are from Morocco, and that they are from mosasaurus or spinosaurus (I am doubtful of this). I was hoping you could share some insight as to what you think they are from? Thank you all!
  9. Anomaly from Penn Dixie

    Enlarged and brightened:
  10. Fossilized Eggs? Found in Missouri.

    Not likely that they are eggs, especially the first one. Think about it logically. Look at the thickness of the "shell" (and no, that's not yolk inside). Have you ever seen a hatchling of any species break its way through an eggshell, either in person or TV or in a movie? Very weak and usually very fragile. How could it possibly break its way out of an egg with a shell that is that thick. It would be the same as you trying to beat your way through a brick wall. You could probably beat your way through some 1/4" thick pine. Now scale that down to the size of that egg. How thick would that pine board be now? How thick is the shell of a chicken egg? A robin egg? The other very good reason they are probably not eggs is that they show no evidence of pores. Look at the shell of a chicken egg with a jewelers' loupe that has at least 10-power magnification. You will see what is meant by "pores". The paleo prof will probably tell you the same thing, but hey, if you have personal access to a pro, go for it. One-on-one learning is one of the best roads to travel.

  12. Dinosaur-killing Asteroid Mark on North Dakota

    Great idea probably would inflate prices but thats okay. In the end we are really not talking about a lot of money for the Feds
  13. Ancient Dino Skull???

    Something that you may have fun investigating is how it got out of the cave and into the creek. Some geo-detective work might be fun.
  14. Tiny Hell Creek Theropod Tooth

    It could be DR but without a clean base cannot be certain. It has some of the characteristics of one.
  15. Dinosaur-killing Asteroid Mark on North Dakota

    To clarify, @jpc, do you mean permitting to collect vertebrates for personal collections on federal lands? Obviously, there is no need for a government permit to collect on private property.
  16. please help identify - colorful bone with chop marks

    To answer you question, even though it does not help ID, someone can still explain why they have different colors. In a nutshell, the ground is a chemical soup, and when iron comes into contact with bone, shell or maybe even agatized fossils, it will turn them red, if it is carbon, it will turn it black. Each color has a list of elements and chemicals that turn it that color, the beauty from your bone is from the rich concentration of chemicals that it was buried with. Sometimes, like a mammoth molar tooth I own, it can even be blue, green, purple and other exquisite colors. Red and black are quite common but it still makes for beautiful fantastic fossils. Hope that helps.
  17. Im not sure what you have here its not a Tyrannosaurid phalanx. Bonec looks like a mess, avoid
  18. Fossil ID

    Looks like a piece of agate. May have some dendrites in it.
  19. Possible Horse Tooth

    After scrolling the geologic map. That specific spot and all around that spot are Pleistocene, meaning this tooth was very likely 2.5 - 0.0117 million years ago from the Ice Age, back when Neanderthals covered Europe and Woolly Mammoths and Rhinoceros roamed the US. Something interested is, if you simply go about 4 or 3 miles south, you will reach a huge shale deposit of Permian era fossils. It says 26 different Permian species were found here. That specific spot is 276.3 million years old. If you're going for age, its not far away.
  20. Arizona fossil sites??

    Awesome site thanks very much!
  21. Arizona fossil sites??

    Thanks very much for the tip! Yes, there probably would be issues if I was hauling anything, but I am trying not to get into trouble, so I am content with just seeing things!!!
  22. Arizona fossil sites??

    Thanks very much for the links! They were awesome!
  23. Real or Fake?

    Everyone else already answered the question quite well, so I will simply agree with steelhead9.... Just... Wow!
  24. Looks like a ceratopsian frill
  25. Yup... I meant permitting for personal collecting.
  26. Is this a blastoid?

    I almost see the star shape of a dirty, sediment covered Cincinnaticrinus pentagonus stem. However, I am not seeing blastoid.
  27. Real or Fake?

    Typical example of a very fake sculpture that is modeled on a crocodile skull but these are often sold as Mosasaur skulls. The teeth are real as the others have said and are all likely mosasaur teeth. So yeah, stay away from this monstrosity.
