Trace Fossil: Helminthopsis abeli Ksiazkiewicz,


Double colour image of brown rock with serpentine trail and drawing of worm-like animal
Trace Fossil: Helminthopsis abeli Ksiazkiewicz. Silurian. Siegas, New Brunswick. Collector: R.K. Pickerill, c. 1980. New Brunswick Museum (NBMG 4017). Image width (left) 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. Helminthopsis is likely a feeding trail made by an arthropod or worm-like animal.
