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.

I found these small colorful specimens of naturally polished petrified wood, which over millennia were sandblasted by the strong winds blowing across the Patagonia pampas of Argentina.

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: -
