Sidneyia
''Sidneyia'' is an extinct arthropod known from fossils found in the Cambrian-age Burgess Shale formation of British Columbia. ==General description== ''Sidneyia'' ranged from in length and is one of the largest arthropods found at the site. It is thought to have been a benthic carnivore that walked along the sea floor in search of hard-shelled prey. Gut contents have revealed that ''Sidneyia'' fed on hyolithids (molluscs) and other small crustaceans and trilobites. ''Sidneyia'' was discovered in 1910 during the first day of Charles Walcott's exploration of the Burgess Shale. He named it after his elder son, Sidney, who had helped to locate the site and collect the specimen. The species name, ''Sidneyia inexpectans'', means "Sidney's discovery". About 200 specimens have been documented.
