💡 Everyday Comparisons for Size, Mass & Speed

💡 An estimated body length of about 2 m is slightly taller than an adult human (about 1.7 m), and an estimated weight of about 10 kg is about the weight of a single 10 kg bag of rice (Comparison).
💡 The Australian Museum explains that this dinosaur's feathers were meant for warmth rather than flight, much like wearing a down jacket in winter (Comparison).

#딜롱#Dilong paradoxus

📖 1. Overview

Dilong paradoxus (genus Dilong) was a small tyrannosauroid dinosaur that lived in Liaoning Province, China, during the Early Cretaceous. Its genus name comes from the Chinese for "emperor dragon," and the species name paradoxus means that finding feathers in a tyrannosauroid was unexpected.

🦴 2. Anatomy & Morphology

Fine, filament-like primitive feathers are visible on some specimens, providing the first direct evidence that tyrannosauroids also had feathers. It had a Y-shaped crest formed by two ridges along the snout, long three-fingered arms, D-shaped front teeth for tearing meat, and short legs.

🔍 3. Fossil Record & Paleoecology

Its feathers were likely used to keep its body warm rather than for flight. It is thought to have eaten small animals such as lizards, mammals, and birds, and because its legs were short, it probably could not run very fast.
