Extinct Fish Facts For Kids. Fun Information About Extinct Fishes

Extinct fish were incredible aquatic creatures that swam in ancient oceans, rivers, and lakes. These fish included armored giants with thick bony plates and strange prehistoric fish with unusual shapes. Many ancient fish were designed with heavy armor for protection and powerful jaws for catching prey in the waters where they lived.

Some extinct fish like Dunkleosteus were massive predators over 30 feet long with blade-like jaws that could crush almost anything. Others had thick scales that acted like suits of armor to protect them from attackers. Scientists discover fossils of these extinct fish in rocks and learn about how fish changed over time and how ancient oceans were different from today.
