Hi All, This thing comes from the Morrison formation in Crook county, Wyoming. It's about 2.25 x 1" x 3/8". Any thoughts on what it is? With the veins on both sides, I'm wondering if it's an osteoderm. Thanks!!

I didnt find this, but inherited it from my dad who passed away last year. He got it from his friend,( 1990s i think) who passed away shortly thereafter. In 2011, it was put on display at the local museum as an 'indian relic'. It was also sent to 2 colleges for analysis. I was told that it was determined not to be man made which dismissed the artifact idea. This is what i can tell u from what little i know ofit.... it was found in Macon county, NC, USA. It was stored at WCU until I asked the museum to return the item last year. I think its an osteoderm fossil? Thanx for any info. Weight 50.2 pounds Dimensions 12" long x 9" wide x 6" deep approx.

Hi all, I saw this interesting specimen online. It is labeled as Ankylosaur dermal scute, was found in the Hell Creek Fm., Hill County, Montana. Size is 4,8 cm x 3,2 cm (1.88" x 1.26"). These are the pictures provided: What strikes me about this specimen is the shape of the bony base and the grained surface. My knowledge about osteoderms is rather limited, so I was wondering if anyone can support or refine the given ID? The only image I found so far that resembles that shape, as opposed to the flat sided scutes, is that of an thoracic osteoderm (https://www.researchgate.net/publication/276289070_Nuevas_evidencias_de_dinosaurios_de_la_Formacion_Puerto_Yerua_Cretacico_Provincia_de_Entre_Rios_Argentina): Thank you for your time and help

A couple of curious finds from yesterday: First: A small osteoderm (33 x 25 mm) from a Glyptodon. The edges look like they have JUST been broken but looks are deceiving. The bottom edge is almost like a knife blade. I am curious on whether others have found/seem similar shape/size/edge and determined the placement of the osterderm on the edge of the shell. Second: What appears to be an Ungual, or toebone. There seems to be muscle/pressure marks similar to other unguals in the the 1st two photos and curious indentations (red lines) on the 3rd photo. All suggestions appreciated. Jack

I know the stingray teeth and the coral, unless someone can provide species. What about the “Osteoderms?” Not sure about the tiny one and the white one? Rocks?? They just looked suspiciously “boney.” The holey one might be too porous to be an Osteoderm? I’m thinking the big one looks like a tortoise? Looking forward to posting lots more!

I believe this is a Holmesina osteoderm (my first), but please correct me if you think otherwise. From a north Florida river. Thanks! -Zach

At first I thought this was a neural bone from a turtle but now I'm wondering if it might be a mammalian osteoderm (3cm long x 1cm thick). From a north Florida river. - Zach

Possible Cretaceous Osteoderms Found In Central Alberta Badlands. Please Help ID
Backcountryhiker posted a topic in Fossil ID
While hiking in the Central Alberta Badlands Near Toleman in Red Deer River Valley came across two pieces of fossilized matter that looked very different than most of the bone fragments I have encountered while on similar outings. If I was to take a wild & uneducated guess I would say they look like they could be osteoderms? Any help to ID these strange pieces would be greatly appreciated. Thank you In advance..thumb.jpg.5cc4882b159d8b5df1a09ecf02ccabb8.jpg)

Every now and then something weird shows up in my sifter. Look at this cute little guy. Hexagonal shape with a faint raised area in the middle. Texture, shape, thickness all seem right for a giant armadillo, but the size is tiny. I've never seen one this small. Can someone confirm or deny this? Could this be from a baby/juvenile? Could it be a baby glyptodont. I'm stumped.

Did not do well yesterday with the additional foot of water due to the storm, but found this little osteoderm. I don't think it's tortoise because it hasn't got the perimeter feature at it's base and it has a much more dense outer layer. Has anyone seen something similar before? I have several sloth osteoderms, but this doesn't have a similar texture to those either.

This carnivore coprolite was found in the Bull Canyon Formation (Upper Triassic - Norian), Quay County, New Mexico. It contains numerous fine, boney inclusions (white). There also appears to be a small jaw inclusion that has a shape similar to amphibians. Originally, I couldn't figure out why there would be so many finely crushed bones. It is not something I usually see. When bone fragments are present, they are usually larger. That said, fibrous osteoderms are also found in the same area. I have included an image of a fairly large one. They are made up of fine, boney fibers that have a configuration similar to woven fiberglass. So here is what I am wondering: 1. Could the fine bone fragments be the indigested remains of these boney osteoderms? Perhaps from juveniles? I do have some small fragments (somewhere), so I could dissolve them to see how they fall apart. 2. Does anyone know what type of animal had these fibrous plates? All I could find is information on osteoderms from phytosaurs and aetosaurs. Neither of those appear to be fibrous. I have found osteoderm fragments of that type in coprolites, but they look nothing like this. I know some of the Triassic amphibian-like tetrapods had osteoderms, but I haven't been able to find information on these. Since the shape of the jaw in the coprolite has a similar shape to those animals, I'm thinking they may have had this type of osteoderm. Of course more than one type of prey may have been on the menu. Osteoderm Magnified Osteoderm I've been away from the forum for a while, so I'm hoping there are new folks out there that specialize in Triassic critters. As always, thanks for looking! @Carl @MarcoSr

Found this in South Texas sandy gravel matrix. Pleistocene era. It's pretty small. But could this be a glyptodont osteoderm? It doesn't look like the turtle/tortoise pieces I normally find. The seams are very pronounced, and the grain on broken places is very fine and not as spongy as the turtle pieces.

Hello ! This one is one of my first fossil . I bought it nearly about 6 mo ago as Partial Ankylosaur osteoderm (scute) from Hell creek formation , Montana . I have a hard time distinguish it from ceratopsian frill ... need help to confirm/correct ID on this bone and I wound love to know what is the main feature that distinguish Ankylosaur scute from Ceratopsian frill bone ?? thank you in advance ! Guns

Found these on the beach in Jacksonville Florida so Pleistocene. They appear to be some kind of scute. Are they glyptodont edge scutes? Tortoise leg spurs maybe? The first one looks like two fused together. One in the second group doesn’t actually come to a point but is otherwise very similar.

So, I found a few chunks of osteoderms in an area that floods quite often. I wasn't even sure what they were at first, only that I *thought* they might be. But they were completely covered in mud and I was super-careful picking them up and getting them home. One separated from the large chunk. But now I have no idea what to do! I did leave them outside in the rain a few days; they were mostly uncovered when I found them anyway and have been sitting in sloppy mud for an eternity, so I figured it wouldn't hurt. So there was a lot of mud that came off but they're far from clean. I'm not sure what to do next. I have a slight idea of the general area of the body these came from but the chunk is not lying flat and I don't know how to clean them to even see what I'm really working with. Are they going to all separate if I mess with them too much? My boyfriend said he'll get me whatever PaleoBond products I want (he's overwhelmingly supportive of my obsessive fossil hobby) so is that what I should be looking at? I've never felt "in over my head" with fossils before but I'm really at a loss with this. Any assistance, opinions, thoughts, speculations, or anything else would be appreciated.

Location: South Texas Found: Gravel, sand, low water Estimated time: Pleistocene I've been searching through info on scutes, osteoderms, reptile fossils, and types of turtle shell and plastron parts because we seem to have a lot of those in our area, but I'm having a hard time telling the difference. These are my best guesses, and I'm hoping someone can educate me on the differences. FRAG 1--I think this is a large turtle/tortoise scute fragment, but I'm not sure how to tell the difference between neural, costal, central, etc. FRAG 2--I believe this is an osteoderm (because it looks like skin instead of part of a shell?), but I'm not sure the type. Maybe alligator? FRAG 3--My husband thought this may just be a rock, but I thought it looked like a fossilized shell plate of a turtle. It's relatively thin. We see a lot of these on the river. FRAG 4--This looked like another osteoderm to me because it has a similar texture on top to Frag2. But it's much thinner and the edges are more defined. Any info would be a big help! Thank you. --Brandy

This is a chunk I found in the Horseshoe Canyon Formation, specifically in the Horseshoe Canyon area. It’s shape and ridges look almost identical to a small Ankylosaur/Nodosaur osteoderm, but the texture suggests a random chunk of ironstone. I’m leaning towards ironstone, but I think there’s a chance it could be a really smooth osteoderm. Would any of you guys be able to tell for sure? Thanks!

I found a unique reddish colored 45mm thick fossil while on my walk yesterday. It is pentagon shaped. Longest distance is from side 6-4 and is 9cm. The dorsal side is darker than the ventral. Four of the sides are smooth. Side 6 has a smooth surface and is size of a quarter. Found in area of Pleistocene material. My guess was neural (4) from a tortoise. Based on drawing in Hulbert's book The Fossils Vertebrates of Florida (p. 122). The thickness of this fossil is what is raising the question for me? ID help is greatly appreciated. SIDE 1 SIDE 2 SIDE 3 SIDE 4 SIDE 5 SIDE 6 SIDE 7

Unique two-color fossil throughout. Found in Venice, FL. The fossil is 6cm x 6cm x 2.5cm. Other fossil material in the area ranges from Meg teeth, whale vertebrae, Equus. My thoughts were of an osteoderm. Their is a raised portion at the break on the dorsal side. ID appreciated.

Found on the Brazos River southwest of Houston, Texas. I originally thought that this was an alligator osteoderm, but it lacks the distinctive boss in the middle of the bone. Looking around on the forum, it seems to match tortoise osteoderms rather well. Can someone confirm? I've found carapace fragments from both hard and softshell turtles before, but never one of these. I didn't even realize tortoises had osteoderms until now. What part of the body do they come from? As you can tell from the pictures, the bone is a decent size, so would this have to be a giant land tortoise or something else. Honestly, I'm pretty out of my depth with this one. Also, if someone could recommend any sort of books I can use to help identify the Pleistocene fossils I find in Texas, that would be appreciated as well - it's starting to seem like the Florida guidebooks on the subject are going to be the closest I can get!

Unidentified Osteoderm fragments from South Texas Pleistocene gravels
Woodgrainstone posted a topic in Fossil ID
I recovered these osteoderm fossils from a small gravel mining prospect off the Nueces River in Live Oak county, Texas about 50 miles from Corpus Christi and the Gulf of Mexico. Deweyville Formation fluviatile terrace deposits of Pleistocene to Holocene age. I am thinking giant armadillo, Holmesina, and some kind of crocodile. Thanks for your information, I found these over a decade ago.
