I know the general shape is right for a spinosaur toe claw, but I know spinosaur claws are a significantly faked thing, so getting someone who really knows what they're looking at, is the way to go!

Can anyone identify these as spinosaurus bones. Ive come across these pictures with very little information, other than apparently spinosaur bones from Morocco. I think the verts look clearly spinosaur, but I'm not very familiar with spinosaur long bones, although they immediately struck me as looking a little off. Maybe them being flattened is throwing me off. This seemed like a perfect opportunity for not just help learning spino long bones, but also while dealing with details like that, which can interfere with "standard" identification. In the 4th picture, the fossil on the bottom right--is that a vert with a long bone next to it? It's positioned like the sail of the vert, and seems to be attached to the vert but something about the bone looks wrong for part of the sail, to me...maybe that it looks like it's rounded along the length's edge, which I thought was not how they were shaped(if I'm wrong, I could also be just picturing dimetrodon sail spines...well, or just plain wrong, of course)? ...As well as looking just like the other long bones present. Thanks for any and all help!

Can anybody tell what this vertebra is from? I believe it's from Kem Kem. *would this be a rib cage vert?

Hey, a question I have always wanted to ask is about dinosaur relatives, more specifically what do we mean when we refer to two dinosaurs as cousins ? Do we mean that a kind of dinosaur(for example baryonyx ) lived in an environment but at one point a group got separated by land and this group got to live in another part of the world so that group resulted in adapting to another environment and becoming a different dinosaur (for example spinosaurus ) or do we mean that a dinosaur is an ancestor of another dinosaur (again for example baryonyx evolved into spinosaurus)? This may seem like a really basic question to ask but I haven't really been able to find an answer so if someone answered it would be great.

Following the debate about whether spinosaurus was quadruped and could actually swim and if it was bipedal and couldn't I came across a theory that S. aegyptiacus was bipedal and S. morrocanus was quadrupedal what are your thoughts on these theories?
-
So when I was taking a better look at my spinosaurus teeth I noticed that in the enamel part there are lines coming out from bottom to top, are these created by minerals or it was some kind of blood vessels or veins from when the animal was alive? Thanks.

Baltic amber and spinosaurus tooth.
anastasis008 posted a topic in Is It Real? How to Recognize Fossil Fabrications
So I recently got this Baltic amber and I found out that there is a test that includes water and salt and if the amber sinks then it's fake but if it floats, it's real and mine sank but I'm not sure could you please examine it yourself? And also the spino tooth if you can. Thanks

Hello so could someone please explain the situation with sigilmassasaurus and spinosaurus was it the same dinosaur? was sigilmassasaurus bigger? Thanks
-
Going really basic here being new on the fossil game i wanted to know how a fossil gets created because i have read that the bone gets replaced by rock or sediments and they take its original form but if that's the case then we are not holding teeth, we are holding rocks in the form of teeth when holding a fossilized tooth for example. I don't really know so if someone could please explain to me if the fossil is actual tooth like it was back then or it becomes rock and the general process it would be much appreciated.

So i have a small fossil collection and i want to learn how to study teeth and their anatomy the teeth i already have are from spinosaurus, mosasaur, carcharodontosaurus and megalodon if anyone could help me learn how to do it i would be really thankful. Thanks.
-
So having a small fossil collection i have thought of the possibility of studying the fossils especially the dinosaur teeth but the problem is im not a scientist so i don't know how to study them so if someone could tell me if cheap fossils like these could be studied and how it would be largely appreciated. (Collection includes 2 spinosaurus teeth, a meg tooth, 2 mosasaur teeth, mammoth hair, carcharodontosaurus tooth) Thanks.

So i recently visited this forum and i read somewhere that we haven't yet discovered spinosaurus legs and its appearance regarding its feet and legs may be just speculation. The argument that was made was whether spinosaurus was a species of crocodile rather than a dinosaur because he may had small legs. So could that be the case?
-
So after following nizaar ibrahim's study in 2014 I learned that spinosaurus walked on four legs and it spend a lot of time in water being a good swimmer. But recently I saw that some new studies have been published and then some others and I have lost track so if someone could please inform me about the latest discoveries and tell me if spinosaurus was a good swimmer and if he walked on four it would be much appreciated.

Although the paper is paywalled the abstract provides some interesting insights The hypothesized aquatic habits of Spinosaurus have been called into question, and the distribution of aquatic habits within Spinosauridae remain unclear. New spinosaurid specimens from the Kem Kem beds of Morocco reveal aquatic adaptations in the cranium. 1) Elevated orbits and bending of the frontals placed the eyes atop the skull, as in semiaquatic animals such as crocodiles and hippos. 2) Two morphologies are present, a smaller morph characterized by narrow, triangular frontals, and a larger morph characterized by broad, subrectangular frontals overlapping the prefrontals. The two morphs suggest two distinct spinosaurine taxa, and are tentatively referred to the spinosaurines Spinosaurus cf. aegyptiacus and Sigilmassasaurus brevicollis, respectively Another interesting point in the abstract: The appearance of giant semiaquatic dinosaurs may have followed the disappearance of giant pholidosaurid crocodylomorphs, suggesting that the extinction of large crocodylomorphs was associated with the rise of dinosaurs as apex predators in the freshwater ecosystem in North Africa. https://www.sciencedirect.com/science/article/pii/S0195667117303427 Aquatic adaptation in the skull of carnivorous dinosaurs (Theropoda: Spinosauridae) and the evolution of aquatic habits in spinosaurus Thomas M.S.Arden, Catherine G.Klein, SamirZouhri, Nicholas R.Longrich From outline images frontals are shown. @LordTrilobite

I thought I would share this. A gift for my 6-year old nephew's birthday. An amazing Spinosaurus model/toy with working jaw, highly detailed, and an actual Spino fossil tooth, approx. 150 myo. I know if I were a 6 year old crazy about dinosaurs, which I was, and still am, would go berserk over this gift. I almost want to keep them for myself, haha. and Happy Mothers Day to all of the moms out there! KP

I am thinking about getting this spinosaurus tooth from this website and i was wondering if it has any restoration or repair or if it is fake. this is the only picture i found on the website.

I thought I’d post some of my favorite claws from my collection. I’m curious what people think about my ID on one of them and I have no idea what the last one is. ID help with that one would be great! (All measurements are straight line) Spinosaurus hand claw 4 1/2” Kem Kem Beds, Morocco Repairs, but I see no restoration Acheroraptor Temerytorum foot walking claw 1 7/8” Hell Creek Carter County, Montana No repair or restoration (at first). However, the tip broke off during molding and it was lost. 1/16” restoration done to the tip now Two Acheroraptor killing claws. The larger one is 3 1/8” and the smaller is 1 9/16” Hell Creek Powder River County, Montana Large claw has restoration to the top 1/4” of the articulation end and 3/4” to the tip Smaller claw has restoration on 5/8” of the tip Same claw as above, with size perspective Other side... Acheroraptor Temertyorum digit I hallux claw 7/8” Hell Creek Slope County, North Dakota No repair or restoration Acheroraptor Temertyorum hand claw 1 1/4” Hell Creek Powder River County, Montana Restoration to 1/2” of the tip I originally thought this this was a Pachycephalosaurus claw, but Troodon’s posting on TFF makes me now believe it’s Thescelosaurus Hell Creek Powder River County, Montana No repair or restoration Side view.. Troodontid walking foot claw 1 1/16” Hell Creek Wibeaux County, Montana Looks like restoration to 1/4” of the tip Possible Microraptorine hand claw 5/8” Hell Creek Carter County, Montana Small amount of restoration to the top of the articulating end and 1/8” of the tip Same claw... Microraptorine killing claw. Related to Hesperonychus sp. 7/8” Hell Creek South Dakota Restoration to 3/16” of the tip Same claw for size comparison... Curious what people think of this one.. I believe it to be a Troodontid killing claw 3/4” Two Medicine Formation Unfortunately, no locality info on it Looks like the tip was glued back on, but no restoration Other side... Now I have no clue what this could be and I’d love some help. I bought it as a new collector awhile ago with very little knowledge. It was sold as a baby Anzu foot claw and the seller said Black Hills Museum ID’d it. I think it’s actually mammalian. Any thoughts? Size comparison Articulating end (sorry for the poor pics)

Spinosaurus claw - fake
Jaimin013 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi all the seller says that this is a spinosaur claw from Kem Kem however it look a fake to me and or/carved out of a bone or some other material. Not too sure what to make of the blood groove either as that's how alot of fakes can be spotted but again that looks carved out too! See above shape just doesn't look right especially around the tip area crack above..

A distal caudal vertebra of a Spinosaurid. What's slightly unusual about this vertebra is that it's slightly more slender than most Spinosaurid caudal vertebrae, which have a more square shaped centrum as seen from the lateral side. I am currently uncertain whether this is individual variation or that it might be taxonomically significant.

Hi everyone, Im looking at a bunch of stuff that someone got from the big fossil expo this month, but I want to be sure of what is what before I do anything. There's a few things way beyond what I could potentially get, but I'm just curious about in general. These are all Moroccan, and most, if not all, are Kem Kem. are these first 4 pics spinosaur? With the teeth I know the 2 on the top&left are probably carchar teeth, but I'm wondering about the other 2. In the 2nd picture, I'm guessing the right one is a spinosaur vert, right? What about the other one? I'm sure it would probably be very hard to tell with just a single rib, but could the rib be spinosaurus? It seems to match some museum spino skeleton ribs, but that's the best I can figure out:/

Can some one tell me if this is nice Spinosaurus tooth? It has been repaired at the tip. Is the repair a big deal? It is a little over 4"
