Loc: https://www.geopark-thueringen.de/entdecken-erleben/nationale-geotope/standard-titel Age: Triassic, Keuper For wchich Archosaur, this tooth belongs? I know that it's hard to say, but maybe somebody can do this

From the album: Triassic
Revueltosaurus was a Pseudosuchian, on the branch of the Archosaurs more closely related to the Crocodilians than the Dinosaurs. Despite the serrated teeth, it is thought to have been herbivorous. -
I buy this tooth from Morrison Formation (Colorado), as a "Goniopholis sp." I think the tooth belong to the family of goniopholididae but not to the genus Goniopholis. The tooth is 0.5 inch.

Hello dear members, Today I'd like to talk about my latest fieldtrip, to the Late Triassic tracksite of Zone, Lombardy prealps, Italy. However, I'd like to make it clear that it involved no fossil collecting, because of the scientific interest of the site and of italian laws, that prevent (almost) any form of this activity. I know there is the "Fossil sites" section, but I thought that here my post would have reached more people. I apologize in case this is not allowed. Let's not waste any more time! Italy is quite well know for its tracksites, in particular those bearing dinosaur t

Found these in East Central Arizona. A deep wash has cut through a rock ledge containing lots of the footprints. Still working on trying to get some of the bigger rock slabs hauled out.

ID requested: Triassic Bull Canyon Formation microfossil teeth (Norian Age)
ziggycardon posted a topic in Fossil ID
Hi! I recently aqcuired quite a lot of "microfossils" to kick off my Triassic collection, as I personally find it one of the most interesting time periods and while I am aware possibly not all of them are ID'd correctly I just wanted to get some nice fossils from this time period regardless of their ID's. All the fossils I acquired are from the Bull Canyon Formation, Dockum Group, San Miguel County, New Mexico, USA (Norian age) But I myself am not very knowledgeable yet in this material as I just started my collection but I am aware that some if not most of the ID's on these fossils -

Hello all, I just picked up this pretty vert and am not quite sure about the ID. The seller advertised it as Coelophysis, but it doesn't seem to be a match. It's from Bull Canyon formation, Quay County, New Mexico (Upper Triassic). It measures 2 1/2". The seller provided good pictures, so I've attached some of those. I can provide more and even take some of my own if needed! Thanks, and hopefully we can figure out an ID on this one!

Rauisuchians are some of my favorite prehistoric beasts, rather specific but I'm wondering if anyone on here on the forum has any material to show I'd love to see. So far I've been only able to obtain postosuchus teeth and recently begrudgingly missed out on some Batrachotomus kupferzellensis.

Absolute EARLIEST gastrolith presence (Archosaur lineage)?
ErichPryde posted a topic in General Fossil Discussion
First of all, hello to all of you on the Fossil forum- My name is Erik. newbie here, first post. Secondly, I'm exceptionally curious as to what organism in the fossil record has the first confirmed gastrolith (non-exolith) presence. I found and read through Fruitbat's research, and he had some very interesting articles about gastroliths, some of which I've seen, some of which I have not. I feel that Gastroliths are incredibly important to Archosaur evolution because they fulfill much the same role that differentiated teeth for thorough mastication do in mammals. Of course, proving -
Here is another peice of my work, this profile is on the Stegosaurus and once again I would like to see what you all think but keep in mind I kind of wrote this in a biased way, as in I used the theories I think are true without mentioning other ones so Forgive me for that. But hey, At least it's pretty simplified. Stegosaurus is one of the Most well known of all dinosaurs along with the T.rex and the Velociraptor. Despite this very, very, very, few people know what it actually looked and behaved like. For example the Stegosaurus has Sexual Dimorphism which means a difference in t

I found this tooth while searching my collection of Sussex Wealden, Hastings bone bed. Similar to the small size ornithopod dinosaur Hypsilophodon premaxilla teeth, but this species can be ruled out. It is more similar to the small ornithopod Echinodon, Purbeck beds, Dorset premaxilla teeth. The crown is smooth and asymmetrical. The root curls up at the end, similar to some Iguanodon teeth in original early illustrations of the Iguanodon species. I prepped the tooth out completely from the matrix. Tooth is very small being 5mm long. Can anyone help me with identification of this tooth?
