Cambrian suspension-feeding lobopodians and the early radiation of panarthropods
TLDR
A Bayesian approach to cladistics supports the view that a semi-sessile, suspension-feeding lifestyle characterized the origin and rise of Panarthropoda from cycloneuralian body plans.
A Cambrian unarmoured lobopodian, †Lenisambulatrix humboldti gen. et sp. nov., compared with new material of †Diania cactiformis

TLDR
The study augments the morphological diversity of Cambrian lobopodians and presents two evolutionary extremes of cuticular ornamentation: one represented by the Humboldt lobopODian, which was most likely entirely “naked”, the other epitomized by †D.
Cambrian lobopodians: A review of recent progress in our understanding of their morphology and evolution
A three-dimensionally preserved lobopodian from the Herefordshire (Silurian) Lagerstätte, UK
TLDR
Thanahita distos joins only seven other known three-dimensionally preserved lobopodian or onychophoran (velvet worm) fossil specimens and is the first lobopODian to be formally described from the Silurian.
A new fossil mantis shrimp and the convergent evolution of a lobster-like morphotype
TLDR
Mesozoic eumalacostracans represent an important ‘experimental set-up’ for research on factors leading to convergent evolution, the understanding of which is still one of the puzzling challenges of modern evolutionary theory.
The evolution of a key character, or how to evolve a slipper lobster.
Carboniferous Onychophora from Montceau‐les‐Mines, France, and onychophoran terrestrialization
TLDR
A fossil species from the Late Carboniferous Montceau‐les‐Mines Lagerstätte, France, informally referred to as an onychophoran for more than 30 years is described and is considered the most compelling candidate to date for a terrestrial Paleozoic onyChophoran.
The impact of taphonomic data on phylogenetic resolution: Helenodora inopinata (Carboniferous, Mazon Creek Lagerstätte) and the onychophoran stem lineage
TLDR
The presence of H. inopinata in the Carboniferous demonstrates the survival of a Cambrian marine morphotype, and a likely post-Carboniferous origin of crown-Onychophora, and demonstrates that taphonomically informed tests of character interpretations have the potential to improve phylogenetic resolution.
Evolution of reproductive strategies in dictyopteran insects – clues from ovipositor morphology of extinct roachoids
TLDR
The ovipositor morphology of various fossil forms of dictyopteran insects is described, presenting examples from different fossil deposits, which show the entire range of ovipOSitor morphologies, from very long forms over forms with Ovipositors partly reduced in length to modern-appearing morphologies.
Reaching across the ocean of time: A midge morphotype from the Cretaceous of Gondwana found in the Eocene Baltic amber
Non-biting midges (Chironomidae) have a fossil record reaching back into the Triassic. The non-biting midge ingroup Libanochlites Brundin, 1976, was so far known from a single species. Fossil…

A Rare Onychophoran-Like Lobopodian from the Lower Cambrian Chengjiang Lagerstätte, Southwestern China, and its Phylogenetic Implications
TLDR
Antennacanthopodia gracilis new genus and species is described and interpreted here as an “unarmoured” lobopodian from the Chengjiang fossil Lagerstätte (Early Cambrian, ∼520 Ma), Yunnan, southwestern China, furthers the understanding of early lobopODian diversification.
Morphology of Luolishania longicruris (Lower Cambrian, Chengjiang Lagerstätte, SW China) and the phylogenetic relationships within lobopodians.
An armoured Cambrian lobopodian from China with arthropod-like appendages
TLDR
D. cactiformis is described as an ‘armoured’ lobopodian from the Chengjiang fossil Lagerstätte (Cambrian Stage 3), Yunnan, southwestern China, remarkable for possessing robust and probably sclerotized appendages, with what appear to be articulated elements.
A Cambrian micro-lobopodian and the evolution of arthropod locomotion and reproduction
TLDR
The lateral orientation of the limbs and their anchoring spines of the new lobopodian imply that early arthropods were crawlers rather than walkers, and the morphology of O. evamuellerae aids in a clearer picture of the early evolution of arthropoda.
Cambrian Derivatives of the Early Arthropod Stem Lineage, Pentastomids, Tardigrades and Lobopodians An ‘Orsten’ Perspective
TLDR
‘Orsten’-type preservation is the phosphatisation of cuticular surfaces without any further deformation and has yielded completely three-dimensional fossils, mainly arthropods at scale of 100 μm—2 mm, implying that the ancestry of Arthropoda lies even further back well in the Pre-Cambrian.
New early Cambrian animal and onychophoran affinities of enigmatic metazoans
TLDR
A new 'armoured lobopod' from the Chengjiang fauna is described and shows close affinity with the enigmatic Microdictyon, and soft-part anatomy suggests that the group has affinities with the Burgess Shale 'lobopod', Aysheaia.
A POSSIBLE ONYCHOPHORAN FROM THE MIDDLE PENNSYLVANIAN MAZON CREEK BEDS OF
TLDR
A lobopod animal described from two specimens preserved in siderite concretions from the Middle Pennsylvanian Francis Creek Shale, Illinois, characterized by a long, vermiform trunk bearing 21 or more pairs of short, lobose limbs ventro-laterally placed.
Palaeontological and Molecular Evidence Linking Arthropods, Onychophorans, and other Ecdysozoa
TLDR
Analysis of DNA sequences from many genes together with morphological characters involving the cuticle and its molting strengthen the grouping of cycloneuralian worms and arthropods as Ecdysozoa, identify the velvet worms (Phylum Onychophora) as the closest living relatives of arthropoda, and interpret segmentation as having separate evolutionary origins in arthropod and annelid worms.
Re-investigation of Mimetaster hexagonalis: a marrellomorph arthropod from the Lower Devonian Hunsrück Slate (Germany)
TLDR
The phylogenetic position of M. hexagonalis as a member of the Marrellomorpha is confirmed, but remains to be explored within the broader frame of euarthropod phylogeny.
The Lobopod Animal Aysheaia pedunculata Walcott, Middle Cambrian, Burgess Shale, British Columbia
TLDR
Aysheaia pedunculata is one of the rarer animals in the Burgess Shale, occurring in association with arthropods and worms, and to an exceptional extent with sponge fragments, and it is not placed in either group, nor in any taxon of higher rank than Family Aysheaiidae.
