Soon, inspired reconstructions of the Cambrian bestiary began to create a stir at paleontological gatherings. Startled laughter greeted the unveiling of oddball Opabinia, with its five eyes and fire-hose-like proboscis. Credibility was strained by Hallucigenia, when Conway Morris depicted it as dancing along on needle-sharp legs, and also by Wiwaxia, a whimsical armored slug with two rows of upright scales. And then there was Anomalocaris, a fearsome predator that caught its victims with spiny appendages and crushed them between jaws that closed like the shutter of a camera. "Weird wonders," Harvard University paleontologist Stephen Jay Gould called...
...even as Wonderful Life was being published, the discovery of new Cambrian-era fossil beds in Sirius Passet, Greenland, and Yunnan, China, was stripping some of the weirdness from the wonders. Hallucigenia's impossibly pointed legs, for example, were unmasked as the upside-down spines of a prehistoric velvet worm. In similar fashion, Wiwaxia, some scientists think, is probably allied with living bristle worms. And the anomalocaridids - whose variety is rapidly expanding with further research - appear to be cousins, if not sisters, of the amazingly diverse arthropods...
