New Study Challenges Previous T. Rex Theories

A new study challenges the 2023 claim that Tyrannosaurus rex had intelligence comparable to modern monkeys, suggesting instead that T. rex's brain size and neuron count were overestimated. Researchers argue that intelligence in extinct species cannot be accurately predicted based solely on neuron counts from endocasts. The study emphasizes the need for multiple lines of evidence to assess prehistoric intelligence, concluding that T. rex was likely more akin to smart giant crocodiles rather than primates.
