Early armored dinosaur from Texas lacked cousin’s club-tail weapon, but had a nose for danger
First-ever CT scans of the early armored dinosaur Pawpawsaurus campbelli reveal that although the Texas dino lacked its cousin’s club-tail it had a sharp nose for danger. A relative of Ankylosaurus, Pawpawsaurus’s saving grace from predators may have been an acute sense of smell, says vertebrate paleontologists. Pawpawsaurus lived 100 million years ago, preceding Ankylosaurus by 35 million years. CT scans allow scientists to determine how the animal’s brain functioned.
