Science meets art: Tiny trilobite gets huge makeover

At less than a centimeter in size, Agnostus pisiformis might not look like much, but a new series of larger-than-life sculptures is giving the arthropod its due as one of the most ubiquitous and recognizable Cambrian fossils.

First trilobite eggs found in fool's gold

Trilobites were one of the most successful groups of animals to ever scurry across the seafloor, thriving for more than 270 million years. But how they reproduced has long been a mystery, since no fossil had ever been found with preserved eggs or genitalia. With the discovery of a cluster of trilobite eggs preserved in pyrite in upstate New York, however, scientists are getting the first glimpse of how these early arthropods reproduced.

Down to Earth With: Paleobiologist Nigel Hughes

I first met Nigel Hughes, a paleobiologist at the University of California at Riverside (UCR), in 2010. He took me on a brisk walk through the UCR Botanical Gardens, where the trees kept us cool in the hot Southern California sun while he told me all about trilobites.

Did tidal zone trilobites lead the way onto land?

With their Cambrian-defining ubiquity, 270-million-year longevity and impressive diversity, trilobites often rank as people’s favorite sort of fossil. Now a set of 500-million-year-old trace fossils found in Tennessee is potentially expanding the trilobites’ territory from the deep ocean all the way inland to the resource-rich Cambrian tidal flats. But whether the tracks mean that trilobites were part of an ecological bridge that helped animals transition from the sea onto land to colonize the empty continents is up for debate.
