Ancient Species -
Arthropods

Arthropods are animals with an exoskeleton, a segmented body and jointed appendages. There are probably tens of millions of species of arthropods living today - most of them undiscovered or undocumented. They include insects, spiders, scorpions and crustaceans.

SpiderSpider

Soft-bodies ancestors of the arthropods first appeared late in Proterozoic Period (about 600 million years ago). Trilobites became dominant in the Cambrian Period (590 to 505 million years ago); arachnids first appeared in the Silurian Period (434 to 408 million years ago); insects appeared about 385 million years ago in the middle of the Devonian Period.

Beetle

The "great extinction", which wiped out the dinosaurs, at the end of the Cretaceous Period (66.4 million years ago), seems to have had little effect on the arthropods.
