Overview

• A new study disputes earlier research suggesting T. rex might have had primate-like intelligence.
• Researchers emphasize the need to consider multiple lines of evidence when assessing extinct species' intelligence.
• Neuron counts, previously used to estimate intelligence, are now considered unreliable for such assessments.
• Findings suggest T. rex's brain structure was more reptilian, with less complexity than previously thought.
• The study encourages a reevaluation of dinosaur intelligence, highlighting the sophistication of reptilian cognition.
