  1. Shark or Mosasaur Vertebrae?

    I found this in the gravel bed of a creek today in Grayson County, TX. Is it a shark vertebrae, or possibly mosasaur? Thanks for any help.

  6. I found this last weekend in the Grayson Formation in Tarrant county, Texas. I have never found a Cretaceous gastropod that was so squatty. Most that I find are elongated to some degree or another, but there is no elongation to this one. This was posterior end down in the creek bed embedded in the limestone. I popped it out, but I guess part of it remained in the limestone. I tried to prep the matrix off, but I can’t tell where the matrix ends and the shell begins since it appears to be a steinkern. There is no ornamentation on it at all. It is about 36 mm at the widest whole part, but looks like it was at least 50 mm wide at one time. I can’t tell how wide the aperture or last whorl was. The total height of the gastropod is 20 mm tall. The overall shape is lenticular. I don’t think there are many lenticular gastropods in the book I have. I couldn’t find one that matched it. Top view (which is actually the posterior end of the shell) Side view Bottom view (which I believe is the anterior end of it) Any help at all would be appreciated.
  7. Almerarhynchia virgiliana

    New genus and new species first described by Dr. Sebastian Calzada Badia in: C a l z a d a , S., 1974. Almerarhynchia n. gen. virgiliana n. sp. del Maastrichtiense de Figols, Prepireneo catalan. Acta Geológica Hispanica, 9 (3): 92-97. http://digital.csic.es/handle/10261/7365. ID of the specimen confirmed by Dr. Calzada.
  8. Mystery fossil (dinosaur? Cretaceous?)

    Hey all, Can anyone help me ID this fossil? It was found at an antique store with no information. Its density and coloration really reminds me of something from out west, like Hell Creek or Lance Creek. There's also a a semi-circle pattern of holes towards one end that reminds me of a crocodile's bite. Any thoughts on the possible ID or if its something besides a croc bite?
  9. Fossil? Funny rock?

    Hi everyone! What about this one? It was found in a well-known fossil site, an old cretaceous sea, in central Spain (Maranchón, Guadalajara, Spain). I would say the texture suggests a living creature of some kind. Too bad it would be a small fragment.
  10. ? ammonite

    Hi can you help me with this , it looks like a gastropod, I found it in an area of sulaiy formation , cretaceous , it is small 3 cm by 2 cm . could be uncoiled ammonite or it is a small gastropod ?
  11. I was just going through a box of fossils that been sittin here in my office for awhile now. Besides lots of other cool stuff I ran into this little beauty. Diplomystus poweri from Hajoula lebanon and Cretaceous in age. I bought this about 20 years ago. I think its real? I only have my readers on at the moment and parts of the head look a bit fishy? No pun intended. RB

  13. Nice day to all here. Today I have here something " UFO " for me. Localization : Czech Republic, allegedly limestone pan, Cretaceous period. It was between limestones parts. The part in red circle is really hard like carapace - not possible to cut by knife edge ( outdoor good knife ). So what it can be ?
  14. I found this tooth in the late Cretaceous North Sulphur River of Ladonia, Texas. I’ve yet to be able to identify this. Seems to be Pleistocene perhaps? Any ideas?? Thank you in advance!
  15. Please help ID Coprolite?

    My kids or I found this rock in a stream near our house. It was in late cretaceous green marl. It seems coprolite shaped to me and seems to have impression fossils in it. Coprolite is a common find at the Rowan Fossil Park a few miles away in Sewell, NJ.
  16. Greatings to all from Czech Republic. Please somebody have some ideas or somebody know ? It is a relatively heavy section filled with a grey silvery mass, irregular spherical shape. Its from place included in the late cretaceous period where was shallow sea and limestone, cretaceous subsoil. Nice evening to all and sorry for my anglish :-)
  17. Please help ID round bone

    I found this round bone in a streambed of green marl near Sewell, NJ. According to the Rowan University Fossil Park a few miles away, their green marl is Cretaceous. I think it's bone because of the spongy texture. I thought it was recent at first (my daughter found a recent jawbone with teeth in the stream) but this feels rocklike and sounds rocklike when tapped on a hard surface.
  18. Please help ID Shell? Scute?

    At first I thought this might be half of a fossilized mollusk, but maybe it's crocodile scute, which is a common find at the Rowan University Fossil Park a few miles away. Maybe it's something I don't know about. Hopefully it's not just another rock I found it in a streambed of Cretaceous green marl.
  19. Hipster Macraster

    When I saw the beard on this echinoid, the name stuck. Duck Creek or Fort Worth fm, North Texas. I don’t find them often with such a luxuriant plumage of spines, so I’m reluctant to prep further for fear of knocking off the fuzz.
  20. I appreciate all the feed back on my handful of Sulfur River finds and im enjoying being on here and being able to share my love for fossils with y'all. Here is a very special find for me I found it the day after being in a major car accident that I was very lucky to be able to walk away from with only bruises. The Flight museum I use to work for was not to far away from a secret creek that I use to hunt during lunch break, It had earlier formation's of the Western Interior Seaway, Austin Chalk, Kamp Branch etc. I've found several good Ginsu shark teeth aswell as Ptychodus Whip, and other good sharks teeth along with some fish verts and a snout from a baby Mosasaur. So the day after the accident I decided to take my mind off the ordeal by hitting the creek during lunch and feeling blessed I was alive and able to walk so just as im heading out of the creek after finding some teeth I stumbled upon fish scales sticking out of the gravel and picked up this Pycnodont and is a pretty good specimen. So It is a very sentimental piece giving what I was going through when I found it.
  21. Hello! I went to Monmouth County New Jersey (Big Brook area) today and found three things I need some help on. The first one is the object I believe has a chance to be Pleistocene. It measures a little over 6 inches long. In the second group of pictures, I think that bone is Cretaceous, any ideas on what it is? Per the fish jaw; all of the jaws I have found in the past were identified as Enchodus but I have heard about a different type of fish here (needle fish?) and was wondering if it could be that. As always, all help is greatly appreciated! -Frank @Carl @non-remanié
  22. Sponge on a stick...

    Hi again, Didn't think I should bother you guys with another sponge, but this is a bit peculiar and I can't find anything about sponges on sticks? This was found in the Kristianstad Basin, Cretaceous period. It is heavily erroded and mineralized, but probably a sponge. It seems to have a circular growth around what seems to be a stick of some sort. They seem proprotional, so I figure they grew together, but they might not be the same spieces? (the stick + the sponge). The images does not make the fossil justice, but it is a very voluminoes sponge with bulges that reminds of glass sponge. The stick is circular in the bottom and more flatt in the top. It might not have reached tremendous heights...? Questions: Would a sponge grow on a stick? Why would a sponge need to reach height if it is not drawing energy from sunlight? How would a sponge like this pump water? I can't find any "sucking holes" Shouldn't a sponge with sticks be more branching? More than one branch? All the best/ Linus
