Environmental indicators
All trilobites lived in marine environments. However their habitat must have varied greatly, as indicated by their adaptations. |
 |
General morphology
Trilobites were generally small creatures, around 2-7 cm long although some extreme sizes have been found from 3 mm to 70 cm. |

The World's Biggest Trilobite
A team of Canadian paleontologists working along Hudson Bay in northern Manitoba has discovered the world's largest recorded complete fossil of a trilobite, a many-legged, sea-dwelling animal that lived 445 million years ago. |
 |
Trilobite Growth
Growth of trilobites involved a process of moulting caused by the growth of the body within the exoskeleton becoming too large to be contained. |
