💡 Everyday Comparisons for Size, Mass & Speed

💡 An estimated body length of about 1 m (representative value for the genus) is similar to the length of an umbrella, and a weight of about 2 kg is the same as a single 2 L bottle of water (Comparison).
💡 The fan-shaped feathers at the tip of its tail bring to mind the tail feathers of modern birds (Comparison).

📖 1. Overview

Caudipteryx zoui (genus Caudipteryx) was a small bird-like theropod that lived in China during the Early Cretaceous, and its name means "tail feather." It lived in a later period than Archaeopteryx.

🦴 2. Anatomy & Morphology

Feathers were attached like a fan at the tip of its tail, and its small, weak teeth grew only at the front of the upper jaw, pointing outward.

🔍 3. Fossil Record & Paleoecology

Because gastroliths (swallowed stones) were found inside its fossilized body, it is thought to have swallowed stones to aid digestion. Given its weak teeth, it is estimated to have eaten insects and probably plants.
