The giant insects

Ever wonder how the insect looked like before few hundred million years ? The grasshopper was more than 2 feet long, the centipede was 3 feet long and there were bugs bigger than human. If you are weak heart and scared of bugs then don't read this article.

For the fearless there are more story and picture of the prehistoric bugs throughout the article.

Undersea Squid-Shrimp

Anomalocaris. canadensis

Anomalocaris canadensis looked like a strange 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 its powerful mandibles were used to catch large prey.

Giant Dragonfly

Modern-day dragonflies seem to have an unduly ferocious name; but their enormous ancestor, M. permiana, would have deserved the name “dragon.” 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. permiana’s 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 earth’s atmosphere started to lose its high oxygen levels millions of years ago. And that’s good news for us.

Giant Snail

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 large—for a snail. But now consider that the prehistoric C. giganteum, thought to be one of the largest (if not the largest) 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 ago—and we can only imagine what sort of terror it might have inflicted upon the Spongebobs and Squidwards of that age.

Monstrous Sea Scorpion

Jaekelopterus Rhenaniae

J. rhenaniae fossils were first discovered in Germany in 2007. We now know that the creature was a truly monstrous sea scorpion, reaching eight feet (2.4 m) in length. In fact, a single one of its pincers was more than 18 inches (46 cm) long. A scorpion the size of a crocodile was certainly a predator to be reckoned with; it prowled the seas until the Permian extinction 250 million years ago.

Killer Land Scorpion

Giant Scorpion

P. kirktonensis was another species of scorpion—this time making its home on land. It is thought to have reached over two feet (60 cm) in length. It thrived during the Devonian period around 400 million years ago, and probably ate smaller arthropods and insects—though its sting would have been powerful enough to kill certain animals.

Cameroceras

Cameroceras

Partial remnants of shells indicate that Cameroceras could reach 30 feet (9 m) in length. Cameroceras was probably the largest marine predator during the Paleozoic era; it navigated the deep sea (probably the only kind of sea that could fit it) and waited in ambush for prey. It was almost blind, and it was a lazy drifter like its closest modern relative, the Nautilus.

3
Giant Centipede

Euphoberia

Euphoberia was much like the modern centipede in shape and behavior, but with the distinction of being over three feet long. Fossil accounts of these beasts have been found across Europe and North America. Scientists aren’t exactly sure of its diet. But even the modern giant centipede, which only reaches about ten inches (25 cm) in length, can prey on birds, snakes, and bats. Imagine the kind of prey a three-foot-long version could bring down.

Giant Clam

P. platinus

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 the largest bivalves (clams, scallops) ever found. In comparison to the (itself enormous) modern giant clam, P. platinus would have been more than two-and-a-half times as wide, and probably much heavier.

Even-More-Enormous Centipede

Arthropleura

Arthropleura was an ancestor to centipedes and millipedes. It could reach more than eight feet (2.4 m) in length, and the fatter creatures could be several feet wide—think, for a moment, of something like that brushing up against your leg. It was so massive that despite being an invertebrate it probably had very few predators, and it is by far the largest invertebrate species ever unearthed.

Arthropleura lived from the Carboniferous to the early Permian period—throughout what is now North America and Scotland—around 300 million years ago. Strangely, even though its monstrous form would have allowed it to prey on most anything, Arthropleura was entirely herbivorous (as shown by the fossilized remnants of its stomach). It wouldn’t have taken any magic to resize this bug for James’ giant peach.
