💥 How did dinosaurs become extinct?

About 66 million years ago, most dinosaurs disappeared.

What happened?

1️⃣ A huge asteroid hit Earth
2️⃣ Dust filled the sky
3️⃣ Sunlight was blocked
4️⃣ Plants died
5️⃣ Animals lost food

This caused a mass extinction.

🦖 Only non-flying dinosaurs died.
🐦 Bird-like dinosaurs survived and became today’s birds!
