  1. Hi everyone this is matt again today in the creek I found 4 different fossils in the creek . They are called fenestella, favosites, productus and a bryozoan fossil.
  2. coral or part of sealily?

    Could this be a part of a sea lily? It is about 2cm long, surronded by a lot of the stalks of sea lily? or is it a coral? The specimen is preserved in what seems to be a big sponge form ordovicium.
  3. Pliocene boring sponge traces on tooth?

    Hoping someone could help me identify the traces on this tooth? I found the tooth with pliocene fossil shells and the location does have middle to late pleistocene mammal fossils. I'm 90% sure this tooth is from a cape porcupine Hystrix africaeaustralis and the species still thrives in the area, from the pleistocene. If these are traces of a sponge then the tooth is a little older than thought. If it's another organism that has left the traces it could be late pleistocene or holocene with some mineralization taken place.
  4. Fish bone or sponge?

    Another driveway find. Is this a sponge of some kind or possibly and bone from dorsal fin? Kind of looks in the shape of the ulna i cant find any reference on what an isolated one looks like. Can bones be calcified like this? i have no idea.
  5. 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.
  6. History Hounds - Wyoming discovery

    Please help me in identifying this spectacular fossil. I believe it is a spider crab. Any information would be helpful. It is about a foot across.
  7. Kalkberg: Sponge?

    I just remembered this object that I found in the Kalkberg formation. Upon first seeing it I thought it might be a concretion, but after washing it up my opinions have changed. Now I can see many other fossils alongside it and after comparing to other Kalkberg fossils I believe it may be Hindia sphaeroidalis, Is this ID accurate? I appreciate any help.
  8. UKNOWN ORDOVICIAN FOSSIL

    I found this strange fossil last time I went on fossil hunting. Could it be a sponge? Anyone have an idea on what this may be? It was found in Norway, a site of middle ordovicium. Martin
  9. What kind of coral fossil is this?

    Hi, this is matthew again. Is anyone able to tell me what kind of coral this is? Here are some photos.
  10. Probably a sponge but....

    This was found among one of the large chert layers in the permian Kaibab Limestone. The sponge, Actinocoelia, is very common in this layer but this seems different or is at least a different presentation or segment of it. It's nearly perfectly round. It's diameter is 3 1/2 cm.
  11. Hello. Today i found in the same area close to the beach in Greece 4 rocks. Looks like agatized fossilized corals or sponge or something similar. Maybe is only a strange rock. This area in lost of time years have water very rich in silicon. So, can anyone help for identification??? The rocks is very heavy. I have a lot of photos but they need to put only one. This one photo is a broken piece of the rock . It's little from outside and inside. Thank you!!!
  12. Cliona cretacica

  13. Hi everyone this is Matt again. Today in the creek I found this very cool clam fossil. Here are 2 photos.
  14. Mineral, sponge or coral?

    Found this in the same location I found the shell fossils in my previous ID post.
  15. This rock has me puzzled. The sides look like they might be the laminae of a stromatoporoid. The top of the rock though, lacks any trace of mamelons and the wavy lines between them that I typically see on stromatoporoids. Instead the rock is full of Cheerios ;-). So I'm wondering if this is something totally different. Maybe geological? Oddly preserved oolites? But then, what are the layers visible on all the rock's sides? Dimension: 1.5" long. TIA to all! Detail of top: Side:
  16. today In our horse pasture I found this large dirt stained favosite fossil what would be the best way to clean the fossil here is a photo of the fossil
  17. Hi everyone today in the creek I found another favosites hamiltoniae fossil here are 2 photos
  18. Sponge?

    Anybody? Ideas?
  19. Hi everyone this is matt again today In the creek I found a nice favosites hamiltoniae fossil here is a photo
  20. Sponges from the Kalkberg formation

    From the album Lower Devonian Helderberg Group in Eastern NY

    Hindia sphaeroidalis sponges from the Lower Devonian Kalkberg formation. Collected 5/31/20 Rickard Hill Rd. Schoharie, NY
  21. Sponge? Anemone?

    Found this peculiar pattern on a rock containing other fossils from Northern Illinois, from the Silurian period best I can figure. Haven’t seen the like before. Anyone know what it might be?
  22. Age is Miocene-Pliocene. Bryozoan is an immediate thought, but I'm pretty sure that they're quite rare post Paleozoic, and this kind of encrustation is very common in the locality where the specimen was found. Here is a picture: Bonus thanks if anyone knows with some certainty what the bivalve itself might be from the photo, though I doubt it.
  23. I picked this up a while ago from the yard of a rockhound who is now deceased, but they could not tell me anything about it at the time anyway... all they could say was it was likely collected somewhere here on Vancouver Island, which would make it either Triassic Parson Bay/Sutton or Quatsino Formation, or Pennsylvanian/Permian Mt Mark or Buttle Lake Fm. I don't think it's likely to be from any of the younger formations. These structures look suspiciously like sponges to me, but I can't say for sure. They've obviously been silicified, which makes ID difficult. Any ideas? I noticed the feature marked with a red circle while looking thru the photos. It might be indicative of ID or maybe I'm just seeing things. I've not bothered to shrink the photos, as I want people to be able to see whatever detail there is on this thing. Hopefully they will load... I'll post one at a time if I have to.
