Dog-sized dinosaur that ran around feet of giants discovered

Labrador-sized dinosaur Enigmacursor mollyborthwickae, discovered in London's Natural History Museum, lived 150 million years ago beside giants like Stegosaurus. Initially mistakenly classified as Nanosaurus, Enigmacursor is the first new dinosaur displayed at the museum since 2014. This discovery illuminates the evolutionary journey from small to large dinosaurs and erases the Nanosaurus category, indicating a wealth of distinct species from the era.
