Biology:Dalyia
From HandWiki
Dalyia is a genus of worm-like fossilized organisms found in the Walcott Quarry and Trilobite beds of the Burgess Shale from the middle Cambrian.[1] Due to its branching structure, it was previously interpreted as a red alga. However further examinations in 2015 suggest they may instead be pterobranchs, a class of small tube-dwelling worms.[1] It has smooth or faintly lineated stems, which branch into up to four equal branches at branching points. 37 specimens of Dalyia are known from the Greater Phyllopod bed, where they comprise 0.07% of the community.[2]
