A new paper is out online: Gallina, P. A., Canale, J. I., & Carballido, J. L., 2021. The earliest known titanosaur sauropod dinosaur. Ameghiniana 58(1), 35-51. https://doi.org/10.5710/AMGH.20.08.2020.3376 Ninjatitan is recovered as a basal titanosaur in the cladistic analysis by Gallina et al., making it the oldest primitive titanosaur to be described and at last synchronizes the basal titanosaur fossil record with the timing of the divergence between titanosaurs and other somphospondylans in the earliest Cretaceous.

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 enjoy what I was able to get:.thumb.JPG.a18fe0fe080619b337e192327c6e54f1.JPG)

Identification of Patagonia's Theropod Teeth
Troodon posted a topic in Is It Real? How to Recognize Fossil Fabrications
Periodically you see theropod material offered for sale from Patagonia and to a collector that's awesome. Typically its specimens obtained before the embargo laws went into affect from Argentina. My experience in looking at what has been offered is that it's often mis-identified as to locality, age and species. Sellers put commonly known dinosaurs identification tags to their specimen like Carnotaurus with complete disregard to the actual age and locality of where that dinosaur was described. That may simply be the information provided to them but they don't verify it and it's easy to do. The reality is that theropod diversity in Patagonia is huge, over vast collecting areas, several provinces, numerous formations and ages. Understanding theropods from this region is just beginning and little is understood, sound familiar Identification of isolated teeth unless there is something diagnostic about the tooth is virtually impossible. I have a difficult time accepting the notion that local diggers knew all the science around what they were collecting, maintained accurate records and provided detailed information to foreign buyers. It was all about the Peso. A recent publication sheds some light on discoveries and I've attached a couple of images to help with diagnosis of the locality and age of specimens you may see offered for sale. Material from this region is very cool but be careful, don't let emotion take over. Just make sure it's was legally acquired and be prepared to identify it as Theropod indet. and don't be fooled that the name offered is valid. Be happy you're just having the opportunity to acquire such a rare specimen. Evolution of the carnivorous dinosaurs during the Cretaceous: The evidence from Patagonia Fernando E. Novas, Federico L.

Hello! I'm relatively new here, but I've been coming to this site for years to look at the great photos and read the discussions. I started this topic to share some of my own research that's going on right now about mass mortalities of marine invertebrates in Patagonia, Argentina. Over that past couple of years I've been working in Argentina, studying fossils (mostly decapods and mollusks) which were killed en masse by volcanic ash. We found some really interesting things in our first trip to the Valdes Peninsula, and documented that volcanic ash can have a killing effect on marine fauna even hundreds of kilometers away from the eruption! I'm also describing a new species of marine isopod that was found preserved in volcanic ash right now. This work is really exciting to me because there is a huge opportunity for new discovery. I hope to describe the numerous different effects volcanic ash has on marine ecosystems, and how they recover from catastrophic events. The ash also plays a really important role in fossil preservation processes, which I also hope to test and describe. I recently launched a "crowd funding" campaign on a website called experiment.com to help raise funds to go back to Argentina for a more comprehensive study of the mass kill sites we know about. If any of you are interested in learning more about the research, or donating to help support it, you can find a video, and other info at http://www.experiment.com/deathbyvolcanicash. I'm also interested in any comments or thoughts anyone has on this topic. I'm always looking for new field sites which may involve volcanic activity and marine fossils, and my research is also more broadly related to mass mortality events in the fossil record in general, so if anyone has any insight into any of this, please comment! Also, if anyone is in the Cleveland area, I'll be giving a talk to a local fossil club on Saturday, May 7th, so if anyone is interested, let me know! -
