Question on the age of the Carcharocles (Otodus) megalodon fossils from Punta Médanos locality, Argentina
Joseph Fossil posted a topic in Questions & Answers
Recently I found a really interesting article rom 2021 describing fossilized specimens (in the form of teeth) of the giant shark Carcharocles (Otodus) megalodon from Buenos Aires Province, Argentina. Here is the article: De Pasqua, J., Agnolin, F., Rolando, A. M., Bogan, S., & Gambetta, D. (2021). First occurrence of the giant shark Carcharocles Megalodon (Agassiz, 1843) (Lamniformes; Otodontidae) at Buenos Aires Province, Argentina. Revista Brasileira De Paleontologia, 24(2), 141–148. https://doi.org/10.4072/rbp.2021.2.05 https://www.researchgate.net/publication/35- 3 replies

"Titanosaur eggshell."
FossilSniper posted a topic in Is It Real? How to Recognize Fossil Fabrications
Claimed to be from the Cretaceous of Argentina. Dimensions are 30 * 29 * 6 mm. No additional information provided. Thoughts? -
We know very little about the bones of the Carcharodontosaurids in the Kem Kem Group. Here is a paper of a new Carcharodontosaurid from Argentina that is somewhat closely related that we can use to compare bones against. Don't forget to look at Supp Files So this paper reports on a new Carcharodontosaurid, Meraxes gigas from the Huincul Formation of Argentina https://www.cell.com/current-biology/fulltext/S0960-9822(22)00860-0 Hand bones

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. -

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
