==Representative taxa== {{multiple image | align = center | width = 300 | footer = ''[[Aysheaia]] pedunculata'' and ''[[Hallucigenia]] sparsa'', two of the most iconic as well as the first described<ref name=":0" /> lobopodians. | image1 = Aysheaia2.jpg | image2 = H. sparsa.jpg }} The better-known [[genus|genera]] include ''[[Aysheaia]]'', which was discovered in the Canadian [[Burgess Shale]], and ''[[Hallucigenia]]'', known from both the Chenjiang [[Maotianshan Shale]] and the Burgess Shale. ''Aysheaia pedunculata'' has a morphology apparently basic for lobopodians<ref name="ReferenceA"/> β for example, a significantly annulated cuticle, a terminal mouth opening, specialized frontalmost appendages, and stubby lobopods with terminal claws. ''Hallucigenia sparsa'' is famous for having a complex history of interpretation β it was originally reconstructed with long, stilt-like legs and mysterious fleshy dorsal protuberances, and was long considered a prime example of the way in which nature experimented with the most diverse and bizarre body designs during the Cambrian.<ref>{{cite book |title=Wonderful Life: The Burgess Shale and the Nature of History |author=Gould, S.J. |author-link=Stephen Jay Gould |year=1989 |publisher=W.W. Norton & Company |title-link=Wonderful Life (book) |bibcode=1989wlbs.book.....G}}{{page needed|date=September 2015}}</ref> However, further discoveries showed that this reconstruction had placed the animal upside-down: interpreting the "stilts" as dorsal spines made it clear that the fleshy "dorsal" protuberances were actually elongated lobopods. More recent reconstruction even exchanged the front and rear ends of the animal: it was revealed that the bulbous imprint previously thought to be a head was actually gut contents being expelled from the anus.<ref name=":15"/><ref name=":2">{{cite journal |last1=Smith |first1=Martin R. |last2=Caron |first2=Jean-Bernard |date=July 2015 |title=Hallucigenia's head and the pharyngeal armature of early ecdysozoans |url=https://www.researchgate.net/publication/279175919 |journal=Nature |language=en |volume=523 |issue=7558 |pages=75β78 |doi=10.1038/nature14573 |pmid=26106857 |issn=0028-0836 |bibcode=2015Natur.523...75S|s2cid=205244325}}</ref> ''[[Microdictyon]]'' is another charismatic as well as the speciose genus of lobopodians resembling ''Hallucigenia'', but instead of spines, it bore pairs of net-like plates, which are often found disarticulated and are known as an example of [[small shelly fossils]] (SSF). ''[[Xenusion]]'' has the oldest fossil record amongst the described lobopodians, which may trace back to [[Cambrian Stage 2]].<ref name=":19"/><ref name=":13"/> ''[[Luolishania]]'' is an iconic example of lobopodians with multiple pairs of specialized appendages.<ref name=":4"/> The gill lobopodians ''[[Kerygmachela]]'' and ''[[Pambdelurion]]'' shed light on the relationship between lobopodians and [[arthropod]]s, as they have both lobopodian affinities and characteristics linked to the arthropod stem-group.<ref name=":18"/><ref name=":20"/>
