“Maybe this change is related to changing feeding habits,” he said. “Predators often need more cognitive abilities.”
Lawrence Witmer, a paleontologist and anatomy professor at Ohio University who studies the sauropod, says these details about Buriolestes’ brain are intriguing because it is an early dinosaur. .
“It gives us a window on the earliest evolution of the brain and sensory system of the largest land-walking animal, the sauropod,” he said, noting that Buriolestes.‘S The inner ear canal and spherical lobe showed use of coordinated rapid movements of the head, neck, and eyes.
“For slow-moving sauropods, there is no premium for maintaining such abilities, and now we know they must have lost these abilities,” because of ancestral species like Buriolestes have them.
Fabien Knoll, a paleontologist at the Dinopolis Foundation in Teruel, Spain, says our knowledge of the primitive dinosaur brain was very little. Buriolestes, are one of the oldest known dinosaurs, and its contemporaries are mainly found in Brazil and Argentina. When the fossil remains appear, the skulls can either be crushed or missing, making this research rare.
It helps unravel a fuzzy but intriguing evolutionary story – the slow transformation of small, nimble, two-legged hunters into big, fearless four-legged guys who eat only plants.
“Research into dinosaur brains is exploding because it’s easier than ever to recreate brain morphology using digital technology,” said Dr. Knoll. “However, brain information in early dinosaurs was hampered by a lack of quality fossils. So I want to say that it is important to continue digging in sites in Brazil, Argentina and elsewhere that are able to provide well-preserved very early dinosaurs.
