Trace Fossil: Paleophycus striatus Hall. Silurian. Siegas, New Brunswick. Collector: R.K. Pickerill, c. 1980. New Brunswick Museum (NBMG 4016). Image width 12 cm. The Siegas Formation is thought to represent a ‘turbidite’ sequence, essentially an underwater avalanche into a submarine canyon. Trace fossils are tracks, trails and burrows left by animals and in these deeper ocean sediments are sometimes the only fossils found. Paleophycus is believed to be a feeding and dwelling burrow made by a worm-like animal.
