Extinct Invertebrate Facts For Kids. Fun Information About Extinct Invertebrates

Extinct invertebrates were fascinating creatures without backbones that lived in ancient seas and on land. These animals included trilobites, giant sea scorpions, and ammonites with beautiful spiral shells. Many extinct invertebrates were designed with hard shells or exoskeletons that helped them survive in their underwater worlds and left excellent fossils for us to study today.

Trilobites were among the most successful extinct invertebrates, with thousands of species that lived in ancient oceans. Some extinct sea scorpions grew over 8 feet long and were fierce predators! Scientists find fossils of these extinct invertebrates all over the world and use them to learn about ancient ocean ecosystems.
