Hello so could someone please explain the situation with sigilmassasaurus and spinosaurus was it the same dinosaur? was sigilmassasaurus bigger? Thanks
-
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.

Hi, All. I came across this yesterday, but couldn't make heads nor tails of it.... I want to think it's not a bone - one side is very smooth, while the other has a tone of small stones attached to it - but the view of the inside has me wondering.... Thanks for looking at it, and telling me what I'm looking at. I seem to have a really long learning curve! Rob @LordTrilobite @Bone guy @Haravex @Troodon

Hi, All. Okay - I'm trying to learn here, so please bear with me! I've been told that many of the teeth I've acquired here in Niger have been croc teeth, and that one of the ways to tell a croc tooth is by a circular base (basil?), while spinosauridae teeth are more oval.... That said, I offer the following two teeth for your informed evaluation! The bigger one is relatively narrow (the side shot with the enamel curving over the top gives you an idea), with the smaller one has a distinct "ridge" on each front/back (I know those aren't the technical terms - sorry!). As always, I greatly appreciate the education that you folks are giving me - thank you! Rob @Troodon @Haravex @jpc @LordTrilobite

Hi, Folks. Thank you so much for the feedback on my first posting of teeth! Apparently there were more than a few crocodiles in the Agadez area of Niger, back when it wasn't desert! I'll post the next set, and follow that up with a posting of another very large fossil from the same area. I truly appreciate the education I'm getting on here!

Hi, All. Here's another "large" fossil I've acquired. Same origin as the others - Agadez area of the Sahara desert in Niger. Based on the feedback I got on an earlier submission, I'm wondering if this could be from a sauropod and, if so, what part of the skeleton? As you can see, there's a lot of mud on it that I haven't tried to remove yet, as I am a complete neophyte and don't know the proper way to do so. I welcome any and all guidance on that too. Thanks so much for all your replies! Rob @Haravex @LordTrilobite @jpc @Troodon @-Andy-

Hi, All. I finally managed to photograph all my teeth with a scale, and am hoping for someone with a lot more knowledge than me (ie: just about anyone on this site!) to tell me what I've got. I've got them divided into 6 different sets of teeth, and tried to photograph them with a bit of logic (teeth in a row, teeth flipped over to show other side in a row, bottom of teeth displayed one at a time in order, etc.). I'm trying to learn the difference between types of teeth (crocodile vs. spinosaurus vs. m-something, etc.), so if there are any common clues, I'd really appreciate the guidance. I was told that the bottom of croc teeth are more perfectly round, while others are more oval in appearance, but that's the limit of my knowledge. I also don't know the difference between "regular" crocodile fossilized teeth, and those of the "super-croc" that has been discovered in the same region of Niger. I've also got two that I can't make heads or tails out of, that I'm hoping for clarity regarding. I guess I'll start with those.... I'll try and space my submissions out, so as not to take up too much time and space. As always, thank you so much for your help and guidance! Rob @jpc @Troodon

Looking for a possible Id of possible fossils on a rock as big as a man's fist. Found it on a solo hike through the desert in Namibia at Terrace bay.

Right in time for the Valentine's day - a titanosaur with heart-shaped tail vertebrae

From the album: Marine reptiles and mammals
A little collection of assorted mosasaur fossils from 2 different places that I got when I first started collecting. 2 different types of vertebrae, one is mosasaur, and the other is a questionable claim of mosasaur, a corprolite that was claimed to be that of a mosasaur, a tooth, & 7 rib fragments. 2 ribs have predation marks, as well as the large vertebra. The large vert has a round tooth indent on the very center. The 2nd rib down has tooth scratches along the surfaces, & 3rd rib down has a round tooth indent in the center, which is probably what caused a strip across the middle to break off. There are 2 other tooth marks on that rib as well, forming a diagonal line from above left of the center indent, breaking off a piece along the top, to below right. -
From the album: Marine reptiles and mammals
Unidentified Cretaceous crocodile species, suggested by multiple people, to appear to be a Dyrosaurus, came from the second phosphatic layer of a phosphate mine(what a shocker!)around the suburbs of Khouribga, Morocco. Original teeth, not replacements. Have gone through and cleaned up the base of some of the ones that had some sand around them. -

From the album: Marine reptiles and mammals
Basilosaurus isis molar(one side serrated, the other side smooth)still embedded in a small piece of jaw bone. sadly I don't have any information about the fossil other than it is B.isis, and was found in Egypt. -
Back in September I posted My Jurassic Park - Theropod Claws from the Kem Kem, the link is attached and now this topic is its continuation. There is more to the Kem Kem than just Theropod Claws (my passion) and I would like to share that with you. The Kem Kem beds consists of three formation: Ifezouane, Aoufous and Akrabou and most of the Dinosaur material comes from there but not all and I'll share a few examples of that. The Kem Kem beds are not a large area in Morocco and I've attached a map to give everyone a good understanding of that and where they are geographically. The best fossils come near the border with Algeria but most of these collecting areas are depleted and today diggers are going to more remote areas. The Kem Kem Region Lets begin with my favorite Spinosaurus aegypticacus (sp.) The teeth can be massive and here are a few examples

I have a question about dinosaurs.
-
I know it isn't that old but I would love an ID.. I just discovered there was a nature photography thread, and I was going through my photos from my trip to the KNP in 2013 and I came across this photo of a giant skull.. I apologize that I can not remember the actual size, obviously I didn't get out of the car to check! I took this photo with hopes of looking back one day and figuring it out, I couldn't get a good focus on it but maybe it is very clear to someone anyhow

I found these teeth on a recent trip to Angola and I want to put them on display in my house, but I want to be 100% sure of the genus of the teeth before I incorrectly label them in the display. Pretty sure these are of the Squalicorax genus. Pretty sure these are of the Striatolamia genus Any help in verifying these teeth would be much appreciated.

Hi, I found this croc tooth for sale and it's labeled as Sarcosuchus. If it is Sarcosuchus, I want to buy it. They didn't put very much info about it, just that it is from Africa. Any help?

Good day to all of you. I have come to discover an amazing site in a remote location of the Serengeti: a dry river bed with hundreds of bones and what looks like stone tools too. The relevant authorities have been informed and i am still waiting for their visit. I have attached a few pics of what i found. Owing to the park rules, I may not pick up a few samples for proper photos. So i tried what i could Since we are not very far from Olduvai Gorge, i do believe this site to be of high importance. I would really appreciate any info on the pictured findings I am going to the site again this afternoon and will try to find bigger pieces and make also better pictures... Hoping to hear from you soon, Best regards, Okaroo
