Prehistroic Models: Arthropoda

Arthropoda meaning “jointed foot”, is the largest animal phylum on Earth. The next question is what is an arthropods? You may know them more commonly as “bugs”. The first arthropods appeared in the fossil record in the Early Cambrian period over 540 million years ago. During the Silurian Period around 420 million years ago, arthropods were some were some of the first animals to adapt to land.
