Big Bertha: A New Challenger for the World’s Biggest T. rex? @TheVividen

Uploaded January 2026 | Updated September 2026, 2 weeks ago

Is the T. rex specimen Big Bertha the new biggest T. rex ever? Bertha the T. rex was found in 1987 and the first paper discussing the specimen has been published. The paper, by Dr. Holly Woodward and her team, discusses Tyrannosaurus growth rate and histology, unlocking prehistoric secrets about the tyrant lizard king's life history. Tyrannosaurus may have grown more steadily than previously thought, countering early assumptions that its young had intense growth spurts as teenagers. Bertha was likely one of the biggest T. rex specimens ever found, comparable in many measurements to giants like Scotty and Sue. Thank you to Dr. Woodward and Dr. Fowler for helping with this video!

$Paleontology News: Theropods Were As Smart as Primates and Developed Culture How smart were dinosaurs? Were dinosaurs as smart as primates? The debate over theropod intelligence is a continuing one, with factors like EQ and neuron density competing for respect in the scientific community. With isotropic fractionation, we learned that its possible for dinosaurs as smart as primates to have existed. Megatheropods may have been among the most intelligent dinosaurs. How smart was T.rex? T.rex, if its neuron density was similar to those of its close avian relatives rather than nonavian reptiles, could be smarter than a baboon. Dinosaur intelligence is a constantly shifting science, but a technique known as isotropic fractionation may hold the key to unlocking the secrets of ancient dinosaur brains. Suzana Herculano-Houzel investigated dinosaur neuron density and discovered that some theropods may have been as intelligent as primates and modern corvids, suggesting complex problem-solving, tool use, and culture building even in the worlds largest terrestrial predators.
