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.

Picked it up as a White stone, but it shouts fossil, has perfect symmetry.

Here are some photos of a geology site near to where I live. The cliff is of the Thornhill rock formation (upper Carboniferous). It was formed in a meandering river channel. I haven’t seen any fossils in the sandstones, but there are some very poorly preserved plant remains in the siltstones. Most of the fossils I find in the coal measures are from coal tips, so even though this isn’t a fossil site, I enjoy visiting here to see the geology.

This is the most unusual Helodus tooth in my collection. It is from the British Coal Measures (upper Carboniferous). If my understanding is correct, teeth described as Helodus simplex, Helodus affinis, Helodus ranknei and Helodus attheyi all come from the same fish, just different parts of the jaw. This tooth looks similar to Helodus affinis but also similar to Helodus attheyi, so I suspect H.affinis was positioned next to H.attheyi and this tooth is from between the two.

Here are my best fossils of Xenacanthiformes. All are from the British Coal Measures (Upper Carboniferous). The first one I suspect may be Orthacanthus due to the width of the cusps, though Xenacanthus teeth sometimes have quite wide cusps. I think all of the other teeth are Xenacanthus. The second one seems very large for Xenacanthus (I suspect around 14-15mm though it’s difficult to tell how far under the rock the cusps go) but I’m fairly sure it’s Xenacanthus rather than Orthacanthus. The third photo is what I believe to be a Xenacanthus denticle.

I recently acquired some fossils that were said to have been from the Breathitt Formation of Leslie County, Kentucky. The majority of the specimens were smaller slabs of rock with fern/horsetail fossils (Neuropteris, Sphenopteris, Macroneruopteris, Alethopteris and Calamites). However, two of the specimens that i received were quite large and I am struggling to come up with an identification for them. Specimen #1 - The rounded fossil measures 27.5 cm (10.8 inches) wide and is 7 cm (2.8 inches) at its thickest point. (second specimen will be in second post due to photo size restrictions)

I found this fish tooth last year in West Yorkshire, UK in an old coal mining tip. I have posted a picture of it on here before but today the light was good to show the colour of the tooth. The teeth from the site where I found this often have unusual colours but very rarely anything as colourful as this. I found the tooth in a block which could have easily been mistaken for a piece of coal. I haven’t put a species name to this tooth because at this size (1cm) there are a number of possibilities. My guess would be Megalichthys but I wouldn’t rule out Strepsodus or Rhizodopsis. The tooth doesn’t appear to be laterally compressed, which I believe rules out Rhizodus. Unlike other West Yorkshire sites I haven’t found any certain evidence of Rhizodonts from this site but there seems to be a higher than usual abundance of Megalichthys remains. Sorry for the low quality photo, the colour doesn’t show as well in bright light.

I found this on a beach in Sutton, North Dublin City, April 15th, 2020. To all intents and purposes it feels like stone and more than likely is. I only post it due to its perculiar shape, what looks like a concentric ring pattern on the concave side, on the opposite side four small striated lines and on the 'top' what looks like a portion of a socket. Thank you in advance for any suggestions, I will be happy no matter what the opinions are. Regards, Waggath

Hi. week ago i found this one along bryozoans and crinoids of namurian age. gastropods and goniatites are also abundant in this location. Any ideas?

From strip mine rubble in Cambria County, Pennsylvania, USA. Probably Carboniferous age. Is this sigillaria? S rugosa, or something else?

Hello everyone, I have recently received these three pieces of Pennsylvanian Flora from Pennsylvania along with some fossils of stigmaria. I have no idea what they may be from and any help is appreciated. The patterns on the first two may be recognizable to someone but I do not have hopes of finding an ID for the last one, I will leave it here just in case. All of the pieces are about 7 cm in length.

We’re currently on lockdown but fortunately have a good stretch of river within walking distance. It doesn’t make up for not being able to get to the coast but it’s better than nothing. Picture 2 is a couple of possible crinoid stems that we found. Pictures 3 & 4 I think are some of the rugose coral that are pretty common round here. Does picture 1 look like it contains any evidence of fossil? I wasn’t sure enough to carry it home but left it somewhere I can retrieve it from later if it is fossil. Thank you in advance

I found these while walking around Bochum/Herne in Germany, whichr is in the Ruhrgebiet and mainly carboniferous. The left one I'm pretty sure it's sigillaria, but not so sure on the right one. Greetings!

I found this plant a few months ago in South Yorkshire, UK. It is from the Pennine Middle Coal Measures formation. Preserved on the plant is an unidentified object which I suspect may be a seed. It seems that the positive side of the object is preserved on the half of the rock with the negative part of the plant. Any help to identify the object would be much appreciated. Thanks, Daniel

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA- 5 replies
