50-Legged Creature May Have Been Top Predator of Ancient Seafloor

Researchers from the University of Saskatchewan reported the discovery of track fossils in the Nov. 8, 2011, journal Proceedings of the Royal Society B. 500-million-year-old trackway fossils were discovered in two locations in Yoho National Park, British Columbia in a geologic formation called the Burgess Shale. The longest track extended more than 9 feet and the footprints were set more than 4 inches apart, suggesting a good size critter with a wide stance.

The researchers compared the tracks to known arthropods of the time period and concluded the likely footprint maker was an ancient cockroach-like creature called Tegopelte. Tegopelte could grow to at least 11 inches long and 5.5 inches wide with up to 33 sets of legs. The fossilized tracks represented at least 25 sets of legs making it the best fit. The tracks suggest a fast moving creature that skimmed along the seafloor capable of making quick turns. The Tegopelte was twice the size of any other arthropods discovered in the Burgess Shale suggesting it was a top predator.

This cockroach-like creature did not survive to the end of the world, but it left behind its many footprints. Thank goodness modern day roaches are not 11 inches long, but if they were, they would be easier to step on.
