  1. Moroccan Mosasaur teeth

    Recently collected a few mosasaur teeth near Bakrit Morocco late Cretaceous
  2. Croc tooth (?) ID

    Hi guys going through my deep box of Kem Kem bits is this. I guess it’s croc, maybe Elosuchus? @Jesuslover340 @LordTrilobite @Troodon
  3. Hello everyone, this is Trevor. Today, 21 October 2017, fossil forum members bucky, frankh8147, Trevor, non-remanie, and Frank's brother, Shane, all went to an NJ Cretaceous stream to do some collecting. The weather was exceptional; still cool enough to wear a sweater but not extremely cold. The day was overall excellent for fossil hunting. We got everything and headed up a small tributary. The finds throughout the entire day were average or somewhat on the lower spectrum of things. However, towards the upper half of the hunt, Frank snagged a pristine condition plesiosaur vertebrae with his hands by feeling in the water. Anyone in New Jersey could heard his triumphant yell of pure elation. Additionally, at the end of the trip, Frank and Shane may have stumbled upon the outer cranial portion of a mastodon skull (Pleistocene), which was apparently just propped up against a rock in the stream. I didn't get to see it but he will surely post it. Well, I shall post my finds. I went to another brook the other day for a little while, that is where the colonial pipe end is from (I did not find it on this trip).
  4. Cretaceous Shark tooth ID

    Found this tooth in N. Texas. 8mm in length. Eagle ford, upper Cretaceous. My guess would be small Archeolamna but unsure. Thanks for any help.
  5. Notopocorystes

    Here is a prep I did of a Notopocorystes (=Ferroranina dichrous) nodule (Eagle Ford Group, Late-Cretaceous, Texas) that I got from @Suvi in a fossil trade. This particular specimen had its limitations in terms of missing legs and parts of carapace. I think it is a molt (note what looks like disarticulated ventral exoskeleton on left of top center photo). Luckily, she included several more nodules that may have more complete specimens. This was a good practice one.
  6. Happy belated National Fossil Day! Hope I'm not overstepping from bounds by posting this, but a few people on the forum have asked me how to get out to the one accessible spot left at the C and D Canal in Delaware. It's tricky to find and doesn't look like much when you first get there. I am leading a trip out there this Sunday for Delaware Nature Society as my somewhat belated, but more publicly accessible, National Fossil Day excursion. We are going to be out on the plain that is a the spoils from the canal for a couple hours looking for treasures, but it won't take more then a few minutes to find your first fossil out there. You are welcome to stay and play until sunset if you like. The web site says "Families with children ages 7 and up," but this does not mean that adults with no children in tow are unwelcome, only that the terrain isn't really good for shorter children. The cost for non-members is a whopping $18 per person. You can keep anything and everything you find. People come home with buckets of Belemnites, oodles of Ostrea (well, Agerostrea), and generous numbers of gastropods. Occasional Echodus and shark teeth are also around, but pretty rare in this spot. You can see some of what I've found out there in my album. The matrix is loose sand. Just walk around and pick stuff up! We'll clear a spot of weeds and do a little sifting, too. Register online today. https://www.delawarenaturesociety.org/DNS/Events/Registration/Event_Display.aspx?EventKey=F17066AS#.Wd9iJUzMz6c While you're at the DNS visitor center to meet for the trip, you can stop inside and see the displays I'll have set up about Fossils from Delaware and beyond. How well can you tell a fossil from a modern shell or a pseudo fossil? Ever looked at a fossil shell under black light before? See the variety of fossils and ages to be found in our tiny state. Or, if you're not going on the trip but just want to explore with smaller folks, sift through the kiddie pool, for canal fossils I collected earlier this year and for Florida shark teeth donated by the Delaware Museum of Natural History. While I'm around I'll be preparing some matrix from Maryland with my handy dental picks. The visitor center activities are free, but trail fees for the rest of the property apply. The visitor center activities will be open Saturday and Sunday, 9-4. For directions, visit www.delnature.org.
  7. Fossil or Faux-ssil?

    From the album 2018 National Fossil Day, Delaware Style

    This game really had people thinking! Can you tell which are which?

  9. Its Spring. A glorious day. prairie Crocus are in bloom, the Meadowlarks are singing and the sky full of migrating waterfowl. First outing this year into the badlands. Headed out just north of Jenner, Alberta and then a trek east along the Red Deer River. Age is Campanian ( Late Cretaceous) about 72 million mya. All terrestrial deposits. A 6 km cycle ride in and then hike another couple. About 3 hours looking for fossils. Its feast or famine. Some hoodoos sterile and then an area dripping with vertebrate fossils. This area also yields a few 'unknowns' All fossils catch and release.

  11. Cretaceous bone

    Recently I purchased a collection of shark teeth from Big Brook, NJ. This specimen came with it. I think it is a reptile humerus, however, it doesn't look like turtle/crocodile bones. I have no idea who it may come from - mammal/lizard/dinosaur? Sorry for the image quality.

    The pool is loaded with sand and local fossils that visitors could take home - oysters, shark teeth, and belemnites! Oh, my!

  15. Fluorescent Fossil Display

    From the album 2018 National Fossil Day, Delaware Style

    About 60% of fossil shells fluoresce. This was a quick set-up using a cardboard box and an ultraviolet LDE flashlight. Flashlights like this are long wave, so they don't work with nearly as many species as shortwave, but for some species it doesn't really matter which wavelength one uses. The $15 flash light was much more expendable than my shortwave light!
