FOSSIL FISH
first appeared about 500 million years ago. Fish are the oldest and most primitive type of vertebrate. The first fish were small, the size of a minnow. They had heavy, bony plates for skin. They lived on the ocean floor and ate through slits on both sides of their throats. Later, fish began to develop gills, scales and fins and learned to live in freshwater, too. Some even developed lungs. Over half the species of vertebrates, both living and extinct, are fish.
