A three-eyed radiodont with fossilized neuroanatomy informs the origin of the arthropod head and segmentation
In addition to being among the most iconic and bizarre-looking Cambrian animals,
radiodonts are a group that offers key insight into the acquisition of the arthropod body plan …

Protomelission is an early dasyclad alga and not a Cambrian bryozoan
J Yang, T Lan, X Zhang, MR Smith - Nature, 2023 - nature.com
The animal phyla and their associated body plans originate from a singular burst of
evolution occurring during the Cambrian period, over 500 million years ago. The phylum …

A new hurdiid radiodont from the Burgess Shale evinces the exploitation of Cambrian infaunal food sources
Radiodonts, a clade of Cambro-Devonian stem group euarthropods, have classically been
regarded as nektonic apex predators. However, many aspects of radiodont morphology and …

Saccorhytus is an early ecdysozoan and not the earliest deuterostome
Y Liu, E Carlisle, H Zhang, B Yang, M Steiner, T Shao… - Nature, 2022 - nature.com
The early history of deuterostomes, the group composed of the chordates, echinoderms and
hemichordates, is still controversial, not least because of a paucity of stem representatives of …

[HTML][HTML] A Cambrian tommotiid preserving soft tissues reveals the metameric ancestry of lophophorates
Among extant animals, Lophotrochozoa accounts for the majority of phyla. 1 This bilaterian
clade radiated rapidly during the Cambrian explosion, obfuscating its phylogenetic …

Are hyoliths Palaeozoic lophophorates?
The phylogenetic position of hyoliths has long been unsettled, with recent discoveries of a
tentaculate feeding apparatus ('lophophore') and fleshy apical extensions from the shell …

Ediacaran metazoan reveals lophotrochozoan affinity and deepens root of Cambrian Explosion
Through exceptional preservation, we establish a phylogenetic connection between
Ediacaran and Cambrian metazoans. We describe the first three-dimensional, pyritized soft …

Phoronida—A small clade with a big role in understanding the evolution of lophophorates
L Gąsiorowski - Evolution & Development, 2024 - Wiley Online Library
Phoronids, together with brachiopods and bryozoans, form the animal clade Lophophorata.
Modern lophophorates are quite diverse—some can biomineralize while others are soft …
