I decided to make a short video of my fossil pine cones from Argentina and did some research to get information so that in the video it would sound like I know what I'm doing. That didnt work too well. I could only find info on the Araucaria pine cones. By any chance would any of you smart folks know what these other cones are. I really need some help with these. Thank you so much. RB

My 'Abelisaurid' tooth from the Anacleto Formation, Rio Ne.....gro Argentina. Initially identified as Carnotaurus, but I suppose rocks don't lie. Further 'research' leads me to believe that the Abelisaurus comahuensis could be the likely suspect(?) Acquired my first Dinosaur book when I was 7, my knowledge is limited but my fascination is endless. The tooth was legally acquired long before the restrictions that are now in place where brought in.

Giganotosaurus Tooth? Or Carcharodontosaurus Dinosaur Tooth Fossil
Kurufossils posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone, I was recently offered this Giganotosaurus tooth. I was wondering if there was a way to distinguish it from carcharodontosaurus teeth from the kem kem beds? Or if anyone can share there opinion on this one, thank you. -
Looks like Abelisaurid week in south america A new Abelisaurid is described here from the late Cretaceous of Argentina : Niebla antiqua For those collectors that have abelisaurid teeth from Argentina this species just adds to the complexity in trying to identify isolated teeth unfortunately its paywalled https://www.sciencedirect.com/science/article/abs/pii/S0895981120304582 Got some better photos

Interesting discovery of a new theropod in South America: Overoraptor Chimentoi. Thought to be closely related to 'Rahonavis' from Madagascar; “...........would indicate that Overoraptor chimentoi and Rahonavis could form a new group of paravian runners, which would be closer to the birds than known raptor families.” http://www.sci-news.com/paleontology/overoraptor-chimentoi-08517.html

Hello Everyone, I have had this beautiful Argentine theropod tooth for 18 months now and the previous owner 25-30 years before the ban was introduced. The locality information is a bit flakey, however I thought it would be worth a try to get some kind of ID if possible if there are any Argentine friends out there with some information to hand. I have taken some measurements as follows: Distal - 12 per 5mm Mesial - 12 per 5mm MCL - 18mm MCW - 10mm crown height - 39mm If any further measurements are n

The Museo Paleontologico Egidio Feruglio- Trelew, Argentina
Jeffrey P posted a topic in A Trip to the Museum
Last week I spent ten days visiting Argentina. Most of that time was spent in Patagonia. Argentina does not allow any private fossil collecting, so this wasn't going to be that kind of trip. On our way back from visiting a penguin colony at Punta Tombo we stopped in Trelew whose number one attraction is the Museo Paleontoligico Egidio Feruglio. It primarily features fossils from Patagonia, dinosaurs and mammals, plus Permian age plants, petrified wood, etc. I got to spend a quick hour there and took some photos. Most of the labels were in Spanish and I didn't have time to take notes. Hope you -
