Arthropods are ubiquitous in all modern habitats and yet their origin remains poorly documented. It is widely thought that their segmented and arthrodized body evolved from the annulated vermiform body of a lobopodian ancestor c. 540 Ma.This major transformation included the evolution of sclerotized and articulated appendages from annulated non-jointed limbs or lobopods.Therefore, Magadictyon cf. haikouensis is regarded here as a rare transitional form between lobopods and arthropods. Besides, together with other lobopods, the morphology of Magadictyon cf. haikouensis demonstrates that the Cambrian lobopods appear to have been diverse and not particularly closely related to one another, and do not seem to ...The association of isolated remains of lobopods with a netlike structure, including plates of Microdictyon rozanovi sp. nov. and sclerites with spinelike process of Onychomicrodictyon spiniferum ...... out lobopods in large view Yasuni NP, Ecuador. ... check out lobopods in large view.

Lobopods are a bizarre group of extinct animals that have a segmented, worm-like body with legs.

Despite many papers devoted to it, the morphology of the Burgess Shale animal Opabinia regalis continues to excite controversy. In particular, the trunk region remains incompletely understood, leading to several recent attempts to interpret the fossil ...Geological setting. The studied specimens were collected from Castle Bank, a Burgess Shale-type Konservat-Lagerstätte, located in mid Wales. Initial publications have focused on the sponge fauna 33, 34, 37, but recently ongoing excavations have revealed a more diverse fauna with members of numerous phyla.Pertinent to this study, other total group euarthropod specimens preserve appendages ...The researchers from Harvard and the New Jersey Institute of Technology who made the discovery describe their finding in a new paper in the Proceedings of the Royal Society B. The ultra-rare fossil can help shed new light on these ancient animals and provide new evolutionary insight into how the 1,300 tardigrade species that exist today evolved.

6. Externally the segmentation is denoted only by the presence of short paired (14-13 pairs) un-jointed stumpy walk­ing legs (lobopods). The legs are ter­minated into curved claws. 7. The head bears 3 paired appendages: (i) One pair fleshy annulated antennae (ii) A single pair of jaws (2nd pair of appendages) and A single-celled microscopic animal of a group of phyla of the kingdom Protista, such as an amoeba, flagellate, ciliate, or sporozoan. Animals that undergo molting (aka ECDYSIS). Two largest phyla in this group are the NEMATODES and the ARTHROPODS. Same thing as saying Kingdom Animalia.Arthropods are ubiquitous in all modern habitats and yet their origin remains poorly documented.
