Rhizodus is probably the most well known Carboniferous fish. I have seen Rhizodus teeth over 20cm in length, which shows the huge size this fish could reach. Fossils of Rhizodus are quite difficult to obtain due to their rarity and because most of them were found a long time ago. I do however have two teeth from Rhizodus. I intend to allow these teeth to be studied by experts if they are of interest to them. The first tooth is a tusk tooth from Newsham, Northumberland, England. It measures 37mm long. The second tooth is from Cowdenbeath, Fife, Scotland. I believe this comes from the Limestone Coal formation, Dora opencast. It measures 42mm.

Bivalves always challenge me. If the ear (is that the right word?) on the left wasn't present, I would have called this Dunbarella sp. But the rounded ear doesn't match any species of Dunbarella I've seen. Maybe another genus, like Aviculopecten? Not sure. From Pennsylvanian black shale in Illinois. Thanks for any help.

I feel like this is a smattering of disarticulated fish bones, but I'm not positive. The preservation is not amazing so even under magnification I'm not sure if these are bone or not. Found in Pennsylvanian black shale in Illinois. Any thoughts? @RCFossils Various levels of magnification

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

Hi all, Here’s an interesting plant find. I discovered it in a locality in Western PA known for producing good plant fossils. I’m thinking seed fern, maybe related to Alethopteris somehow but to be honest I’m not sure what the species is. Any help would be appreciated. Thanks in advance Stratigraphy: Connelsville Sandstone of the Casselman Formation of the Conemaugh Group. Age-Late Pennsylvanian, ~305 MYA

For the last 4 years I have been collecting plant fossils from sites in East Central Illinois. These fossils were all brought to the surface by underground coal mining in the first half of the 20th century. Most of the spoil piles in the area have been graded or flattened out, but a few still remain, standing tall above the flatland. One particular pile is, I believe, the source of most or all of the fossils I find. The shale that makes up the spoil has been fired by the internal heat of the pile, resulting in the hard, reddish material known as "red dog". This shale is then crushed and used as paving material, on trails, parking lots, and construction sites in the area. It's at these secondary locations that I am able to search the material for the impressions of ancient plants and collect them. The shale is pretty smashed up, so complete or large fossils are rare, but the preservation of detail is generally quite good. Geologically, the fossils come from the Energy Shale Member of the late Pennsylvanian Carbondale Formation.

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.

All the local Kmarts went the way of the dinosaur and went extinct last year. I bought a couple display cases for $40 each. I brought it home and just a month ago filled it up with fossils. The wiring was cut from the store in a hurry, so I just left it as is. I ordered a plug and rewired it this morning. The light makes a huge difference.

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 all, after seeing all these nice collections from other members I also want to share the collection of my father and I with you. The collections is of various time periods and sites. We started collecting in 2009 close to home in a quarry nearby Maastricht called 't Rooth (sadly this quarry is close for visitors since 2016). From there on we started visiting other quarries and the collection started too grew massively. We frequently visited the ENCI, Winterswijk and Solnhofen. I will start off with some of the display cabinets
