I recently saw these three spinosaurus claws for sale. Which of these looks higher quality?
-
This popped up online, some one in my local area is selling them, He's not sure what they are but says he believes them to be fossils. Look like claws to me but I've not familiar with this kind of thing. He has no info of where they are from but would like to know what they are.

I can't find any pictures that focus on Edaphosaurus claws, and I can't zoom in enough on pictures to get a clear visual of any claws, so I can't see any differences between Dimetrodon and Edaphosaurus claws are. They're both really small compared to the bodies, so it's hard to see from full body/skeleton pictures, and they wouldn't be from enough angles to be sure. Someone who has dealt with lots of them, including on articulated specimens, has said that they're almost the same, and as far as he knows, but isn't 100% sure about it, the biggest difference, the only one he is aware of, is that Dimetrodon claws are curved on the bottom, like raptor/general theropod claws, while Edaphosaurus claws, equally sharp, are mostly flat on the bottom, like spino toe claws. Is that the case? Does anyone happen to know?

Is anyone familiar at all with Diplocaulus claws? Anything from shape/look, to size? In fact, in many(maybe even most)of the very few pictures that are clear enough to see the feet(of fossils, not art lol)it doesn't look like they really even HAVE any claws to speak of, let alone relatively long ones, but 1 or 2 pictures DO. And for animals that are believed to be heavy diggers, they would probably need to have more than little naked toes. *this is pretty similar to the only other picture of "Diplocaulus claw" I could find, although that is on a for-sale site, not a scientific one:/

Buying a Sauropod Foot Claw?
Troodon posted a topic in Is It Real? How to Recognize Fossil Fabrications
I was reading a paper Fruitbat just posted in his fantastic PDF library, on sauropods see below, and it triggered a concern that I've had for a while for collectors purchasing claws. First let me preface the discussion by saying I'm not a sauropod expert just throwing out some observations and questions. Identifying claws is not an easy diagnosis. Sellers typically put a name, mostly at a genus level, on claws they sell. I have several in my collection and boy they are indeed hard to distinguish between families. Here is a seller offering a juvenile Diplodocus foot claw from the Morrison formation. So is this a juvenile? or just one of the smaller claws from a hand or foot? Also, what's so diagnostic about this claw that one can claim it's from a Diplodocus? A museums view of Diplodocus foot Then there Apatosaurus not much different. I personally believe trying to identify isolated sauropod claws to family level is very difficult since there is very little diagnostic about them. Its a non starter for most except for the most knowledgeable in the field. Issues like age of individual, position in the foot, distortion and preservation make a diagnosis very hard. Here is a seller doing it the right way calling his specimen just Sauropod. I think if your interested in purchasing a claw that you're interested in having a positive ID it needs to be done with an associated foot since they are diagnostic. Another possibility is knowing that a claw came from a Quarry that is predominantly from one type of Sauropod. Here is a seller doing exactly that, selling an Apatosaurus foot. The paper that started this post has a couple of nice views of Camarasaurus feet/claws that you can use for comparative purposes. Tschopp, E., et al. (2015).

Identification of Claws/Unguals from the Hell Creek/Lance Formations
Troodon posted a topic in General Fossil Discussion
A member of the forum asked if I cam put a topic together to help identify claws from the Hell Creek/Lance formation. Its fraught with difficulty since so little has been published and described from these faunas but will attempt to put something together. All subject to discussion and mistakes. Although the focus there is with the dinosaurs of the Upper Maastrichtian its applicable to most of the other faunas of the Campanian and Lower Maastrichtian ages. Ceratopsian indet. This family of dinosaurs include Triceratops, Torosaurus and other large bodied Ceratopsaian yet to be described. Identifying unguals to a Genus/Species level is impossible and these are best identified as Ceratopsian indet. Ceratopsian unguals are best described as being rugose with many pits/holes on the front perimeter of the ungual. There is also a ledge (more pronounced on some than others) on the ventral side as shown by my red marks. I find it difficult to tell the difference between hand and foot unguals of the same size other than the wings are not has pronounced. The more symmetrical the wings are the closer the ungual is to the midline Digit III. Photos are the best way to show what they look like and here are some from my collection Dorsal view Ungual 1 Ventral View Ungual 1 Dorsal View Ungual 2 Ventral View Ungual 2 Dorsal View Ungual 3 Ventral View Ungual 3 An illustration of a Hand (Manus) A photo of a composite foot Leptoceratops indet. A small Ceratopsian in these faunas is a Leptoceratops. Teeth are the most common material found or sold but there are skeletal elements found. Here is an ungual I found in the Hell Creek. The dorsal view is like an isosceles triangle and very compressed. Dorsal View Ventral View Since these are extremely rare here is an additional photo of a associated set of unguals from the Two Medicine Formation An illustration of an campanian foot An illustration of a digit.- 27 replies

I have large stone with this image embedded (Fossil imprint?) among many I acquired to form paths in my gardens. As you can see, it looks like a "claw" - maybe with pad at bottom right of my foot - or it was suggested a "wing" portion? . . . I don't think it is an anomaly. As I do not know where exactly from where the stones came - here in the San Antonio, TX area most stones/rock came from quarries in the surrounding county. Any suggestions are welcome.

I bought a giant box of rocks at an estate sale simply because they were interesting when I got home it was filled with fossils. I've spent weeks researching and haven't made it very far. I know that I have teeth, claws, and clam shells but figuring out where they came from is tricky. I would appreciate any help as I am keeping these for my personal collection and would love to be able to explain what they are. My guess is they were found sometime in the 1940's it's hard to narrow the location as their rock collection has rocks from all of the different states.

From the album Ursus spelaeus (Cave Bear) collection.
Ursus spelaeus finger bones and claws. I'm using my finger as scale so you can see how powerful these critters were! From the Dachstein Mountains in Steiermark, Austria. Pleistocene. -
Half a year ago in Poland on holiday ( i used to live in Poland, but I moved to UK ) I was going for a walk with friends when my one of my friend's suddenly saw a weird "stone" which turned out to be a tooth. We couldn't take it out so one of my friends went to get a shovel ( he lived nearby ) and so we started digging. Then we saw this giant tooth! I We were all in shock! it was just a normal pathway covered with normal stones. Then we decided to dig futher and there was more teeth in the ground! I was amazed as I couldnt find any other types of fossils ( where I used to live ) than annoying Ammonites. After few hours we found many teeth and also weird looking claws? Anyway can anybody identify them? I dont think they are Cave bear fossils as when I typed in on google images "poland cave bear teeth/fossils" they looked much different. They are about 7-10cm long and the claws about the same size. HELP! http://imageshack.us/photo/my-images/190/dscn1337v.jpg/ http://imageshack.us/photo/my-images/46/dscn1330p.jpg/
