At first glance the animals, with their strong hind legs, resembled grasshoppers. But they lacked wings, which most grasshoppers have. Their front legs were studded with thorns, like those that praying mantids use to capture and hold their prey as they eat them alive. But the heads and hind legs of these baffling insects were clearly different from those of a mantis. From above they looked almost like plant-eating walkingsticks. Yet their second body segment was too short for a walkingstick, and their guts contained body parts from other insects, proof of carnivory.
With so many fundamental distinctions in body shape and diet, it took only a few hours to conclude with certainty that these organisms fit in no existing insect order. We would have to create a category for them, one on a par with the flies, the beetles and the termites.
Unbeknownst to science, this chain of life had remained intact for more than 45 million years!
