The findings are mostly evidence of theropods (upright carnivores) with footprints of theropod prey, hadrosaurs or duck-billed dinosaurs. The new specimen's feet show resemblances to feet found in a subgroup of theropods called deinonychosaurs. While scientists continue to debate whether birds evolved from theropods, most studies confirm that birds and dinos share more than 100 anatomical features, including swiveling wrists, wishbone, and three forward-pointing toes. |
