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!!!

Hi everyone this is Matt again. Today in the creek I found this very cool clam fossil. Here are 2 photos.

Found this in the same location I found the shell fossils in my previous ID post.

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:

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 -
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?

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.

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.

Hi everyone this is matt again does anyone know what kind of coral fossil this is ? I found it in the creek today
-
These washed out after a rain from a line along a hillside in southeast Missouri.

I've got this segment of ammonite chamber apparently nicknamed a "cats claw" due to its appearance. It's from the Faringdon sponge gravels. I'm interested to find out what it is attached to the ammonite chamber. Information I've read regarding the Faringdon sponge gravels is quoted below if it's helps. "The sediments of the Cretaceous, Lower Greensand Formation were deposited in a tidal strait some 114 million years ago (Aptian Age). The palaeo-channel of this constrained seaway was scoured from the Jurassic bedrock and quickly colonised by bryozoa, sponges, brachiopods, bivalves and echinoids. Storm surges are thought to have periodically ripped the biota and regolith, mixing the sponges and bryozoans with Jurassic rock and fossil material to form the sponge gravels."

Hi everyone this is matthew again in the creek today I was fossil hunting and found a very nice bryozoan fossil here is a photo

Hello, I was trying to find the identity of some marine fossils I found, and found this great forum! I am from Montana, but have been wintering in Yuma, Arizona. I have been finding all sorts of neat rocks and marine fossils in the desert outside of Yuma where the Colorado river had once flowed into a large ocean. I have found several roundish rocks that seem to have fossilized marine life in them? I was told by a Coprolite collector that is a characteristic of Coprolite found in this area? I would appreciate an ID on the specimens, or speculations as to what they are? Below is one specimen, different angles, notice the square holes!? Thanks!

Can you please help ID this? Found close to the border of WI/IL. It seems spongelike but the inside chambers leave me guessing! NOT a professional. Just like to find cool schtuff'.

Please help me to identify these two fossils. When I picked up these rocks, I thought I had found corals, but now, looking at them from all sides, I'm stumped. What throws me, is that the pattern on each of the two fossils looks the same all around the rock. No vertical structure or growth pattern, anywhere. So even if these are just broken off pieces of a much larger fossil, corals still would show vertical structures on the sides, right? But no "sides" are visible here. Confusing. Thanks so much in advance for taking the time to share your knowledge. #1: Dimensions: width is 2.2cm; height is 3cm, the individual circles vary quite a bit from <0.5mm to >1mm. Detail: #2: I wouldn't mind if this one is geological, as I collect more purely geological rocks than I do fossils, but I don't think this one is just geological. Dimensions: width: 3.5cm; height: 2cm; individual "dots": max 1mm

I picked up this jasper for its banding. Only later, when checking the rock through my hand lense did I discover what I think are a bunch of little rugose colonial corallites at the top and bottom of this rock. If these are indeed corals, all but one lack most detail in the center. If septa are faintly visible, they look differently preserved than on any of my other coral specimens. Mostly it's just circle after circle here, and areas full of "pores". Now that I'm looking at them on my larger screen, the "pores" themselves seem to be corallites - microscopic ones. The black dots are in the center of honeycomb like shapes. I'm confused now, are these the fossilized remains of one or two type of corals, or maybe a colonial coral and a bryozoan? Sorry about the bad quality and distortion of the pictures taken through a microscope lens on my phone. Please help me ID these tiny hurricane look-alikes. As always, thanks in advance. Here a couple of them in various states of preservation. Lots of them have a vug where the center of the corallite would be. Here the circles look like growth rings and in some areas the "pores" are clearly visible. #1: This one is the only one with detail in the center. Septa? #2: a vug at the center seems all that's left here. #3: Just pores in the center, and in between the circles, maybe the faintest lines that could have been septa? #4: Area in between corals, with faintly visible honeycomb shapes: Detail of the above: Another area in between, looking somewhat different again:

Found in northwestern New Mexico in an Upper Cretaceous area. Specimen was wetted with water to bring out detail.
