👉 Anarthropoda is a group of extinct animals that lived during the Cretaceous period, around 69 million years ago. These creatures were characterized by their short, flattened bodies and lack of limbs or appendages. They primarily consisted of small, feathered dinosaurs such as the Dinosauria, including the Tyrannosaurus Rex and Triceratops.
Anarthropods are often grouped together because they share a common ancestor with other dinosaurs, which likely lived in similar environments.
