| Genera | |
The Luolishaniidae[5] or Luolishaniida[lower-alpha 1] are a group of Cambrian and Ordovician[6] lobopodians with anterior 5 or 6 pairs of setiferous lobopods.[1][3][2] Most luolishaniids also have posterior lobopods each with a hooked claws, and thorn-shaped sclerites arranged as three or more per trunk segment.[4][1][2] The type genus is based on Luolishania longicruris Hou and Chen, 1989, from the Chengjiang Lagerstatte, South China.[5] They are presumed to have been benthic suspension or filter feeders.[4][1][3][2]
New specimens of the previously enigmatic Facivermis show that it was a sessile tube-dweller, and part of this group.[3]
A 2023 analysis concluded, on the basis of numerous morphological similarities, that luolishaniids might be the closest known relatives of tardigrades.[7]
Notes
- ↑ Caron & Aria (2020a) elevated this group to the rank of order Luolishaniida, while also naming new family Collinsovermidae within that order, containing the genera Acinocricus, Collinsium,Entothyreos and Collinsovermis.[2]
