![]() Moreover, birds have changed a lot in the past 66 million years. Some are quite smart, like parrots and crows, but others are not as sophisticated. Still, there’s a range of intelligence in birds. “We know that we have living dinosaurs in birds and close cousins of dinosaurs in crocodilians, so we can use what we know about these living animals to bracket the possibilities for dinosaur intelligence,” he says. We can get an idea of dinosaur intelligence based on where they fit into the tree of life, says Carrano. rex intelligence, but it would be challenging to go beyond that for now. He contends that we have secondary ideas that may provide a window into T. “To go back in time and measure intelligence in an ancient animal, it’s really hard to even approach this question in any sort of precise way,” he says. He says we haven’t even mastered measuring intelligence in live human beings. Matthew Carrano, curator of the Smithsonian’s National Museum for Natural History, agrees that there’s a lot that we just don’t know. “We have to be careful to stay within the limits of the data,” says Morhardt. So there’s a lot we don’t know, and it’s best not to jump to conclusions. Still, we also need to be able to map the neuronal connectivity of the brain to assess its efficiencies and to look at how support cells in the brain are impacting brain activity. Rex Brain Size and Neuronsīrain size is important, as is neuronal density. “I don’t personally find this claim to be realistic because brain size only tells us a small portion of the story,” she says. But Morhardt contends that there are too many caveats in the study to be able to take it that far. ![]() rex was about as smart as a baboon, which means they were smarter than we thought. The study, authored by Suzana Herculano-Houzel, even estimates that T.

We also know from the size of the eye sockets that it had excellent vision. rex, we know that it had extra large olfactory bulbs and, as a result, a great sense of smell. “We can get a sense of how much of the brain tissue was devoted to different regions of the brain by being able to analyze the anatomy of the endocast,” says Morhardt. Endocasts are particularly helpful because they show the size of the brain cavity as well as the anatomical details of the brain. In some cases, scientists might also make an endocast or a 3D representation of the brain cavity made in a similar method to a jello mold. The skull can also be placed in a computerized axial tomography ( CAT ) scan, which provides a detailed image of the inside of the brain cavity. “Pretty cool and badass, isn’t it?” Johnson remarked about "Stan," who may or may not be the $31 million man.If the skull has been broken open due to damage, researchers can physically study the insides of the brain. A look on the institute site shows that a "Stan"-cast T-Rex skull with neck costs $17,500. No one knows - for now - but it might be a relief to some is that the institute sold high-quality casts of Stan, and it can still do so as terms of the lawsuit, according to National Geographic.

And, did Johnson decapitate “Stan” to fit in what looks like his kitchen? Paleontologists hoped it would go to a museum allowing them and other scientists to continue to study it. But “Stan” went to a private owner and disappeared, much like he (or she) had done so many millions of years ago in the lonely landscape of South Dakota. In October 2020, London-based auction house Christie’s sold the “Stan” for a record $31.8 million, the highest price ever paid at auction for a fossil, stated a National Geographic article.
