Researchers Find the Ampelosaurus Had a Tiny Brain
Posted on January 26, 2013
Researchers have found that the ampelosaur had a tiny brain. The remains of an ampelosaur found in 2007 at the site of Lo Hueco in Spain have enabled researchers to make a 3D reconstruction of the dinosaur's brain. The ampelosaur was a titanosaur, a group of huge plant-eating sauropods that were dominant during the last half of the Cretaceous.
The researchers say the huge dinosaur (which may reached 15 meters in length) had a tiny brain that was no bigger than 8 centimeters (about 3 inches).
Fabien Knoll, a researcher from the National Museum of Natural Sciences (CSIC), said in a statement, "This saurian may have reached 15 m in length; nonetheless its brain was not in excess of 8 cm." Knoll also says, "Increase in brain size was not favored in the course of sauropod evolution."
The findings were published here in PLoS One.
