Went to the Brook yesterday and found this curious thing. Leaning towards a fish plate and found something called a porcupine fish but can’t seem to find a genus.

These are some of my Burr fish (or similar) mouth plates from Saint Augustine Beach

Just started this beautiful beast. ~22" Phareodus. About 10hrs in so far with the micro jack thinning the matrix before the abrasive prep. Have to build a larger abrasive cabinet to accommodate it. Will post updates here as I make more progress. Cheers David

I found this fossil for sale from a person that have no idea what it is. As a rookie collector I also have no idea what it is. I would appreciate any suggestions and if it is worth buying.

I was finally able to take a trip to the NSR in 2023. We had a good 11 foot rise so I was optimistic. My whole goal this trip was to find a point, I couldn't find one to save my life, I however did find a few cool fossils. I don't know if i just don't have the eye for it or if i am just looking in the wrong places. The last two pictures are of an item im not sure about anyone have an idea? Possibly a set of fused vertebrae with the two end ones broken off? The haul The vert The mosasaur thing The in-situ And the I don't know what this is

Hello friends. It's been a while since my last post and I wanted to share with you my new acquisitions and, better yet, help me confirm the identification of these specimens. 1: The place of origin is Liaoning, China. 2: The place of origin is Yunnan, China. naraoia? 3: The place of origin is Yunnan, China. Isopyx minor?. 4: The last and my favorite (although a bit fragmented). The place of origin is Harbin, China. I appreciate the ID. They are not the best specimens, but I love these pieces.

What Is The Smallest Arcticulated Fossil Ever Found?
Mioplosus_Lover24 posted a topic in Micro-paleontology
I was wondering if anyone ever made the claim to have the smallest articulated fossil, because I think I've got a decent shot! These are the smallest fish I've found so far. There are two Mioplosus labracoides and one Priscacara sp.

I saw this fossil fish online but I cant seem to find any info on pleisotocene fish fossils from indonesia, (I assume its from pleistocene rocks?)

These are from multiple trips between 2022-2023. all from Calvert cliffs, each trip has something unique I would like assistance in identifying so for convenience's sake, I will refer to the items in alphabetical order relative to the numerical trip order. 1A 2B etc. Trip 1 1A pretty sure it is a crocodile tooth, Thecachampsa sp? 1B this is a bone that i found on the beach, im not sure if it's a cetacean atlas or skull fragment. but it's got this weird hole in it on one side. 1C clearly a cetacean vert. probably a juvie dolphin. i think so bc it doesn't have any fused epiphysis. id like to know what part of the spine this would have been on the animal. 1D maybe the wing of a vert? 1E is this anything? or just concretion 1F biggest fossil I've found yet by far! this massive chunk of whale jawbone. I am going to make a separate post in fossil prep to see about the best ways to clean it. 1G maybe a rib? i believe its a bone of some sort. i need to paleobond this one back together. Trip 2 2A definetely a tooth of some sort. not sure if its a croc or a cetacean since the enamel is worn 2B maybe a rib? or vert wing? 2C I think this might be a turtle shell, because its texture is not pronounced enough to be a cookie fragment. 2D maybe a skate osteoderm? 2E 2F 2G Sand tiger shark 2H crab claw with some sort of borehole? any other comments or ideas are as always, appreciated!

Fossil hunting trip at Achanarras quarry, Caithness, Scotland
James_R_V posted a topic in Fossil Hunting Trips
Last week I went upto Caithness hunting for fossil fish at Achanarras quarry. The rocks there formed at the bottom of a huge lake during the Devonian period 385 mya. Most of the fossils I found were incomplete with mostly the tails missing, but I was lucky enough to find a complete diplacanthus, and fragmented cheiracanthus murchinsoni, which I have managed to superglue back together.- 17 replies

A few months ago I found this bone at Red Hill before I learned of the need for a permit but didn't grasp its significance. Later I realized it was a jawbone section with four small teeth in it. Unfortunately I dropped it and the end of the most complete tooth fell off, but not before I was able to take pictures. I have not tried to finalize preparation for fear of destroying the remaining teeth. I can't see any sutures, at least not in the place they would be for a tetrapodomorph, and the teeth look more like Hyneria anyway. However, all Hyneria jawbones I've seen have two rows of teeth, a small one and one with longer fangs. The cross section is also hard to place. The teeth seem to start out round and flatten as it goes up. The first picture is as the bone is now and the second shows what the complete tooth looked like before it broke. Scale bar 1cm broken into 5mm halves. Teeth magnified 20x.

Hi all, I found this fossil on a beach close to the Burren in county Galway, Ireland. It is around 6-7 cm or 3 inch, sorry forgot to put sth next to it for measuring. Would appreciate any ideas on what it might be. Thanks.

Holy grail Dunkleosteus terrelli partial skull for my collection
Pliosaur posted a topic in Member Collections
Hello everyone! I wanted to share a holy grail fossil that I have obtained: a partial skull of Dunkleosteus terrelli found in Cleveland Shale, Ohio This specimen has been confirmed by Zerina Johnson, a leading paleontologist at the Natural History Museum of UK as well as James Boyle who is a leading expert in the field and published academic research papers on Dunkleosteus and other placoderms of the Devonian period. Below is an excerpt from James Boyle on the Dunkleosteus partial skull specimen: "Yes, it's most like a Dunkleosteus based on what I can see. You have both anterior dorsal lateral plates of the thoracic armor there. These are the bones that connected with a mobile joint the head and shoulder regions of the armor. The bone to the bottom left is the internal view of the left anterior dorsal lateral plate. The bone under it is the right anterior dorsal lateral plate in external view. The piece that's skewed to the right a bit in the image is part of the left anterior dorsal lateral plate as well. The easiest way to identify which of the two plates is the external (from the outside) view is that there's a sensory line canal on the one plate (it's straight nearly straight line tracing across the one bone at the top). These are the lateral line system you can still see in some modern fishes and act as pressure sensors to detect movement in the water around the organism. They are only found on the outside of the body." "That oblong bone at the top is probably a piece of the paranuchal plate, but if that's the case it's only a very small fraction of it."

Found what looks like fish jaw with tooth and skeleton. There are many pieces of this fossil but only showing part with jaw. Was found poorly preserved in Pierre shale SD. Wondering which fish species it might be? Thanks!

For a friend of mine. ID'd as a partial fish skull. Found in the KemKem beds. Honestly no idea what it actually is. So give it a shot here.

I found a very beautiful fossil. like a fish fossil

Hi all, seeking some identification help from those familiar with marine vertebrates from the Pennsylvanian black shales (Nebraska, Missouri, etc.) I recently obtained a few ex. Ted White and Bill Rushlau specimens of Romerodus orodontus and a few very nice Iniopteryx rushlaui and one unidentified specimen was included. Just for context for some reading this, W.D. "Ted" White and Bill Rashlau were very prolific collectors of the Pennsylvanian black shales, primarily the states of Nebraska, Missouri and Iowa. The specimens that they collected and cataloged are in many museum collections. The Iniopterygiformes were named as a new order by Zangrel and Case, 1973, with the type species Iniopteryx rushlaui named after Bill Rushlau. Ted White was a recipient of the The Paleontological Societies Harrell L. Strimple Award, which recognizes outstanding achievement in paleontology by an amateur. Gerard Case also received this award in 1992. Location: Hansen Quarry, Papillion, Nebraska. Stark Shale, Pennsylvanian T. White collection notes: Sat., April 5th 1947. Spec. # 8284. "Shark - unknown sp. A 20 x 40 cm. mass of rough textured tissue. up to 7 mm thick in one area. No shagreen observed. General features this is a probable anterior fragment suggesting an individual approx. 1.5 meters in length. 50 or more distinctive teeth unlike any previously found in these shales. These teeth range in length from 5 to 10 mm. unlike the fairly common Cladodus tooth, these have a roughly triangular shape and have only 1 crown or cusp. About 40 of the teeth are partially separated from the mass and are more or less in a normal orientation. A circular 2.5 cm in diameter defined by some more calcified parts may be an orbit or the symphysial whorl." I do not see any features that point to elasmobranch, but the remains do more resemble some of the "blown out" shark remains I have seen from the Penn. black shales. The teeth, which are pretty distinctive, do not resemble anything I can turn up. I also considered that they may be dermal denticles, but the arrangement does not make sense nor can not find any Pennsylvanian aged denticles that match. The "teeth" indeed measure up to 10mm in length, as described in White's collection notes. I am hoping some of the forum members familiar with marine vertebrates from the Penn. black shales can help. Pic of full specimen (teeth circled in red), pic of area with teeth, and a close up of some of the more complete teeth.

Complete Mesacanthus mitchelli fossil from Tillywhandland quarry.
James_R_V posted a topic in Fossil Hunting Trips
I went fossil hunting at Tillywhandland quarry on Turin hill, Scotland today and found a complete Mesacanthus mitchelli fossil. It is probably the best one I have found yet. Both the head and tail are present. The head is so well preserved you can see both the gill rakers and eye socket.

Hello together, I just acquired some little bone and tooth(?) fragments from the rhaetian bonebed near Bebenhausen. Whoever collected them in the seventies wrote "Psephosaurus?, Schmidt page 411" on the label. I think that was rather wishful thinking. There are some bowl-shaped elements of 3-5 mm with a concave side that may show enamel. I tend to think those are some kind of fish teeth, Who can tell me more? Best Regards, J

Hello Fossil enthusiasts! Im new to this forum, and am already here needing help identifying a fossil! I recently came into possession of this fossil of a fish. While I initially believed it to be a member of the Knightia genus, I am now quite unsure what I have here. The man I purchased it from said it was from asia, possibly china, but I am unsure of the authenticity of that claim. I don't have a tape measure on me, but the slate itself is approximately 9cm long. Any help is appreciated!
