Don't Smell These Tulips!

Dense clusters of stalked creatures, rooted in the muddy bottoms of shallow seas some 500 million years ago, would have called to mind a submerged bed of tulips as they swayed gently with the passing waves.
Close inspection revealed that the bulbous, cuplike structure atop each stem, called a calyx, enclosed a unique filter-feeding system and gut.
Notably, the animal’s anus happens to be located in precisely the spot you would position your nose for a sniff, were it actually a tulip.
“This feeding system appears to be unique among animals," University of Toronto paleontologist Lorna O’Brien said in a press release. "We do not know where it fits in relation to other organisms."
