Can anyone help me with this one? Its from the beach at Ravenscar, North Yorkshire coast, The area produces ammonites, belemnites and lots of other marine invertibrates. I am guessing at some sort of fan worm.

Here are two fossils I found today , they are from Southern California marine Miocene rocks. The one with the spike looking thing is around an inch (you can see my leg for scale reference). Absolutely no idea what the first is, the second looks like some sort of plant or arthropod. Thanks in advance

I won't go too into details but basically this I found multiple worm- like organisms preserved on the same chunk of wood-like rock (most likely sandstone?) from the post titled "Petrified Wood?". There are quite a few but it is difficult to get accurate pictures on the specimens. Aside from that, I am clueless to what they are or even if their fossils I could use some more experienced people. If more pictures are needed I'm willing to get more. The first picture shown was a unique specimen I could not find any more like this one so, I'll start with this.

A closed tube-like fossil with delicate ornamentation on sides and a weird barbecue-like surface on the apex, with bryozoan epibionts. From a Polish Callovian locality rich in bivalves, brachiopods, and other fossils. Having looked from all sides, I am certain it is not a chimaera but definitely one tube-like shell, with shell continuous (where preserved) from sides to the apex, similar in shape to a belemnite phragmocone.

So, I've recently came back with a relatively large haul of early Maastrichtian marine fossils, presumably deposited as debris from a nearby reef. Here are some of the ones I'm curious about: Let's start off with this solitary coral: Based on pictures on the internet, I get the feeling that it might be a Cunnolites sp. Next up is what is presumably some type of algae: Next, this... thing. I honestly have no idea what it could be - rudist? gastropod? EDIT: Informed that it is a gastropod. Now, these things. I have a very strong hunch that they're rudists, but I need both confirmation and, if possible, some family/genus level identification. Now, this one stands out to me as it is much flatter/more ellipsoidal than the rest AND seems to have a different texture: What family/genus could this bivalve be? It seems really familiar: And finally, this. I have no idea what it could be. A trace fossil? Some kind of algae? Some rock formation?

Hello everyone I have an interesting bone or tooth I need help with. It's from Yazoo Clay (Late Eocene) Louisiana ,marine environment . It's 45.5 mm long and 8 mm across.Not sure what it is. any information would be appreciated.
-
Found in the upper cretaceous in central Alabama, At first I thought it might be a segment of crustacean appendage but it is too long and irregular. The end folds back on itself. Maybe a shrimp burrow? It looks like it was originally soft and organic. I realize the photo limits the visible details but I can only upload one picture at a time. Overall length is 8 cm. This may help.

These seem to be traces, but have an odd assortment of characteristics. Found in lake shore glacial float. Most likely Tarratine sandstone,a Pragian marine delta related formation. Any thoughts ?

This is from the Wabaunsee Group (Phanerozoic | Paleozoic | Carboniferous Pennsylvanian-Late [Virgilian]) Includes: Wood Siding FM, Root Shale, Stotler Limestone (base ST), Pillsbury Shale, Zeandale Limestone (base Z), Willard Shale, Emporia Limestone (base E), Auburn Shale, Bern Limestone (base BR), Scranton Shale, Howard Limestone (base H), and Severy Shale. Found these unknown objects attached to the interior of a myalina clam shell. This is a marine environment but I'm not sure which layer of the Wabaunsee Group this is from. I've never seen this before so would appreciate any help with ID. I'd be happy to furnish more photos of layer and fossil. Thanks

Oregon Coast Shell Fossil - Please put any guesses even bad ones
NWGeoFan posted a topic in Fossil ID
I figured it was a mollusk, but my knowledge of such is very limited. I have made a shot in the dark that it is Gryphea? But I am unsure if it would even fit the time period (Miocene) or the location of the Astoria Formation in Oregon. Please put any guesses you may have even if they seem totally wrong. By the way Its glossy texture is due to a coating i put on it due to its tendency to flake off pieces, not the fossils look.

An afternoon of sorting through some more micro material has turned up what I suspect is some bird material but with my luck still could be fish. The preservation is correct for bird and the specimen appears to be hollow on the broken end and infilled with crystal. I cannot as yet find any photos of a similar bone in the cretaceous bird material on the net but early days. The specimen is fairly flat so is hard to be sure with the USB microscope. the specimen is 9 mm at the longest point and about 2 mm thick. Thanks in advance for all observations and comments Mike D'Arcy

While sieving micro material from my favourite spot I came across this small specimen. It is 3.5 mm at the longest side so not very big. There is a distinct shine on one side so a first I tended to think tooth but I am unsure. Part of me wants to think it is a tooth from some type of parrot fish. The more logical part of me tends to think it is a fish scale of some type with the end broken off. Due to size I can not tell if the end is broken or complete except for a little wear. At the moment I am open to opinions as to what the micro fossil is With the photo I will go with fish scale? Mike D'Arcy

Hello everyone, Last year I have found a fossil tooth, which I (at first) thought could be an interesting shark tooth fossil - since shark teeth are very abundant in this locality. It is just about 10 mm long, but as I looked at it later, I thought that it must be marine reptile fossil. At home I took my micro-camera and took some detailed photos with some small maginification. Then I was sure it is not a shark tooth. but something else. I have discussed this finding with Daniel Madzia and his answer was that it possibly belongs to Plesiosauria sp., Ichthyosaurus or Crocodylomorpha. He is teropod expert though and suggested me to ask someone who is into marine reptiles. Could you please help me with identification ? Thank you very much. Lenght: 10mm. Unevenly striated, slightly curved, cone-shaped. Circular cross-section. Age: upper jurassic, oxfordian Site: Brno Hády quarry (Moravia, Czech republic, central Europe)

Hi all, I like to collect rocks off the beach and while I'm usually skeptical of anything that looks like it has organic patterns, this one has just totally stumped me and my curiosity is killing me! It looks like it might have belonged to something living but I really don't know. Found in Albert Beach, Lake Winnipeg, Manitoba, washed up in the sand among a bunch of other similar sized rocks. The tooth-like structure is about half an inch tall, and the rock itself is a little over half an inch long. The tooth-like structure has these vertical stripes all around while there are scale-like patterns on the bulbous end. Can't tell if plant or animal (if organic at all). Please help! I'm dying to know. Will happily take more photos on request. Thank you!

Finally got out for a bit of a fossicking trip to Richmond in central Queensland, did not bring much back home but overall a good trip. I went out to get more matrix from the hole where I have found some Mesozoic bird fossils and drop off to the museum the couple of fragments found while sieving through last trips matrix. http://www.abc.net.au/news/2017-04-19/dinosaur-bird-found-in-outback-queensland/8453740?pfmredir=sm Saturday 22 April 2017 - Day 1: Drove 5 hours out to Richmond and after a quick lunch went out to the quarry and went to the spot where I had found 30 odd Ichthyosaur on the last day of my trip earlier in the year to dig deep into to wall of the quarry, but as it is a working quarry much had changed and no luck there so I spent the rest of the afternoon specking and found one nice sharks tooth and half a baby ichthyosaur vert from I spot I had worked over a couple of years back. Yes I already had the other half at home. Early day so back to the pub and watch my team play football. Sunday Day 2: At the quarry by 7:00 and I started to dig down the 300 mm (1 foot) in the spot where the bird fossils came from and by 11:00 I had one bag of matrix in the back of the car and had the rest of the area where I wanted to dig down to the capping layer of rock over the matrix layer. I normally drive back to the caravan park to get out of the sun about this time but the local palaeontologist Patrick turned up and we got to chatting and having a general look around, so I did not go back for lunch until 1:00 pm. I then went for a visit to a local friend’s place for a chat so did not get back to the quarry until about 5:00 pm. I then dug out the other bag and half of matrix from my hole and left the quarry at dusk. I will see what I find in this lot of matrix before I decide where to dig next. Monday Day 3: At the quarry by 7:00 and thought I would have another look around where I had found the Ichthyosaur verts on the last trip but soon decided well and truly gone. I then decided to check along the wall of the quarry at the same level where I had picked up the verts on the last trip and noticed a Ichthyosaur rib in the side of the quarry face. After a quick dig around the rib to see if I could get it out I found more fossil bone so I excavated I bit more and decided there would be too much material for me to dig out and to material looked quite promising to having a fair bit of the skull there even if it was disarticulated, so I gave it a quick cover up and left. I then went back to Richmond to get the palaeontologist from the museum to have a look. I got him at about 8:15 on his way to work and once the museum was open Patrick came out to the quarry. We exposed a bit more of the fossil material and decided there was the potential to be a fair amount of the Ichthyosaur there based on the way the skull elements were facing. As I already knew, we also decided it needed to come out as a full dig and would need a backhoe to dig down to the layer where the fossil was as well as needing several people to lift the sections out and transport back to the museum for preparing. I was a funny feeling recovering the fossil that I had just found. We then pegged out the area and marked it with a Kronosaurus Dig Site sign, to be properly fenced of later. By 11:00 we got back to the Museum and looked a some of the bird material that I and some others had found next to the hole so are associated material. What I will say is with every bit someone finds of the bird material the better picture of what the association is with other Mesozoic birds found across the globe. After a break for lunch I went back to the quarry and did a bit more specking and talking to others out at the quarry. I picked up a turtle jaw in a piece of rock but not much else and left the quarry at dusk. Tuesday Day 4: Up early and on the road home by 6:30 for the five hour drive home and unpack the ute ready to go to work on Wednesday. Mike D'Arcy

Found yesterday in dirt, directly alongside a creekbed in NNW San Antonio. I took a picture of it before I pulled it out then the subsequent photos are post cleaning. I have found many like this but this was different in that the segments were separate but still in the same place. I thought it was a nautiloid but those other pieces with it seemed odd. It's about 5 inches long and 3 1/2 inches tall. Thanks to your help in advance!

Hello All! 100% novice here. I found the item shown below at a local Southern California beach. The first image is when I first picked it up, seemingly covered in tar and wet. The second image is how it looks today, after being washed and dried. It has an almost wood like feel to it, its very light. But the shape of it has lead several people to comment that they think it may be some sort of tooth. So so I come before you, completely clueless, and ask for some expertise. Thanks in advance!

Last fall after working a museum, I returned to a ranch in the Pierre Shale south of Rapid City. One of the students I'd brought with me earlier in the spring of 2016 spotted a chunk of fossil that we originally identified as wood, before we realized that it was a large squid pen! So, right before our classes started we got back together and spent a few days camping on the ranch to excavate it to donate to the museum as well as some other fossil. All kinds of things got in the way, our car broke down, we were driven out of our tents by a thunderstorm, and if it weren't for GPS we would have lost the location of the pen. The site was on a steep, soft hill of shale on the edge of a ravine with a half dozen cattle skeletons from a blizzard back in the nineties. But we got the squid out of the hill and into the museum! Almost a meter long, seems to be the middle of the rachis with a few fragments of the vane

Hello. I found this "thing" on the ocean floor while diving in the Philippines. It looks kind of like a tooth of a marine animal, probably not a shark. Any ideas?

Hi all, I just acquired this interesting specimen that was identified by the seller as Helicodromites mobilis. However, when trying to verify this, the images and description I've been able to find really don't seem to match. The whorls on this are flat and attached to the core. To me, it looks more like a cast of a shark egg case. Are any of you familiar with H. mobilis? Thoughts? Thanks for taking a look!

Ok so I'm brand new here and I'm hoping you guys can help me out. I found this what I think is a fossilized bone (maybe skull) fragment washed up on the beach at westmoreland state park in montross virginia along the potomac river. The area, I believe, is part of the calvert cliffs along the chesapeake and therefore should be from the Miocene. I've been trying for months to figure out what this thing is and the best idea I have come up with is maybe a skull fragment from a miocene dolphin of some kind but I'm honestly not completely sure it's not just a rock. I may have gone overboard with the pictures but I wanted to make sure you guys had the best possible understanding of what this thing looks like. Its about 5cms at its widest point. Thanks for taking a look.

This coprolite is from a marine creature that swam in the Jurassic seas that once covered this parts of England. The dark inclusions that can be seen on the surface are Onychites (cephalopod hooks). In April 2016, the University of Minnesota X-ray Computed Tomography Lab scanned the specimen using a X5000 high resolution microCT system with a twin head 225 kV x-ray source and a Dexela area detector (3073 x 3889 pixels). Many of the images shown here are of individual 3D elements/features within the coprolite that were separated/isolated using Blob3D. The taxonomic classification given is for the inclusions, not the coprolite. Aside from the hooks, it is hard to definitively identify the inclusions without damage to the coprolite. The following is a list of inclusions: 241 hooks of various sizes that are at least 75% intact. 200+ plate-like fragments of various sizes (likely similar to the surface nacre). 19 ellipsoidal structures, possibly forams or parasite eggs. 2 unidentified long, straight conical structures joined at wide end (A) 1 long rod-like structure with a bulbous end (B) 1 unidentified mass that looks like it was the attachment point for 5 rod-like structures (C) 1 1ong cylindrical (rod) structure that tapers in the center. The center density is much lower than the outer shell (D) 1 irregular structure that looks I originally thought might be an ink sack or buccal mass, but the size is wrong. Experta think it is more likely foraminifera (E) 1 irregular structure, possibly a statolith (F) Acknowledgements: Thank you to Neale Monks and Christian Klug for providing input.

I found this recently in an Early Mississippian lag deposit amongst several other fossils, including shark's teeth, bones of unidentified critters, and phosphatized inverts. From my observations, I believe that the site represents an estuarine setting. I don't find any plant material here, but that doesn't mean that terrestrial critters might not show up. I have my own opinions about the piece, but let me know what you think! Early Mississippian Cumberland Plateau Size: approximately 1cm across

This conical, segmented, fossil was picked up off the shores of Lake Ontario in rocks that contain a lot of bryozoan and crinoid fragments. I think it is Devonian, but could someone help me confirm that, and help me understand what this fossil might be?
