Anomalocaris canadensis looked like astrange blend of squid and shrimp. It was three feet (1.0 m) long, with a mouth full of razor-sharp teeth. Fossils found in China show that it was a massive undersea arthropod that lived about 500 million years ago. It probably fed on smaller crustaceans using its bizarre and deadly set of teeth, which resembled an enormous serrated cigar cutter; and itspowerful mandibleswere used to catch large prey.

It strongly resembled a very large horseshoe crab, with a thick armored shell, multiple body segments, and compound eyes. I. rex and other trilobites were rather simple and adaptable organisms, managing to survive for some 300 million years.

The largest snail today is the giant African land snail, which can reach seven inches (18 cm) in length, and which has a shell diameter of three-and-a-half inches (9 cm). Fairly largefor a snail. But now consider that the prehistoric C. giganteum, thought to be one of the largest (if notthelargest) snails ever, could reach nearly two feet (60 cm) in length. The name was a giveaway, really. Paleontologists believe it lived in the oceans that covered France during the Eocene epoch 50 million years agoand we can only imagine what sort of terror it might have inflicted upon the Spongebobs and Squidwards of that age.

Platyceramus was not really a bug, but its length of ten feet (3 m) more than makes up for the technicalities. P. platinus is one of thelargest bivalves(clams, scallops) ever found.

It was almost blind, and it was a lazy drifter like its closest modern relative, the Nautilus.

Modern-day dragonflies seem to have an unduly ferocious name; but their enormous ancestor, M. permiana, would havedeserved the namedragon. It was probably the largest insect that ever lived: its wingspan could exceed two feet (60cm), and its body grew to nearly 17 inches (40 cm). M. permianas immense size has led researchers to think that it may have fed on animals as large as frogs and squirrels in order to sustain itself. The prehistoric dragons are thought to have gone extinct when the earths atmosphere started to lose its high oxygen levels millions of years ago. And thats good news for us.

Arthropleura was anancestor to centipedes and millipedes. It could reach more than eight feet (2.4 m) in length, and the fatter creatures could be several feet widethink, for a moment, of something like that brushing up against your leg.
