The Luolishaniidae[
]
or Luolishaniida are a group of Cambrian and Ordovician[
]
with anterior 5 or 6 pairs of setiferous lobopods.[
]
[ Most luolishaniids also have posterior lobopods each with a hooked claws, and thorn-shaped sclerites arranged as three or more per trunk segment.][
]
[ The type genus is based on Luolishania longicruris Hou and Chen, 1989, from the Chengjiang Lagerstatte, South China.][ They are presumed to have been benthic Filter feeder.][
]
New specimens of the previously enigmatic Facivermis show that it was a sessile tube-dweller, and part of this group.[
]
A 2023 analysis concluded, on the basis of numerous morphological similarities, that luolishaniids might be the closest known relatives of Tardigrada.[
