New controversial study shows how theropods were "smarter" than primates
Pliosaur posted a topic in Fossil News
Although the research regarding this was only published this month, there has been a lot of intense speculation and controversy as to whether theropods especially Tyrannosaurus Rex were comparable to being "primates" of their time. "According to her findings, theropods had as many neurons in their brains as monkeys do today, with the T-Rex boasting "baboon-like" numbers of up to 3 billion neurons. That's a pretty scary level of intelligence for a killing machine the size of a house.With that many neurons, a T-Rex wouldn't have just possessed uncanny cognition. It also might have lived longer, up to 40 years, Herculano-Houzel estimates. That's enough time and smarts to potentially be a social creature with its own culture, like primates and whales, and also suggests they may have worked together, too." Some great sources and videos, feel free let me know your thoughts on this below! The actual study can be found online and reported in the Journal of Comparative Neurology https://www.science.org/content/article/some-dinos-may-have-been-brainy-modern-primates-controversial-study-argues https://phys.org/news/2023-01-phylogenetic-bracketing-dinosaurs-neuron-density.html https://www.sciencealert.com/t-rex-was-a-lot-brainier-than-we-thought-researcher-claims-

Tyrannosaur Rex Premax Tooth condition
Jacobloven posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone! I’ve been thinking of purchasing this T-Rex tooth. As you know they do not come cheap nowadays so I would really appreciate any input. According to the seller it was found in Hell Creek formation, South Dakota and has no cosmetic restoration whatsoever. It’s in it’s found “crushed state”. Approx 3 inches long and 1 3/8 inches wide. Do you see any red flags with it? Thanks!
