Erratum: An early Cambrian agglutinated tubular lophophorate with brachiopod characters
The morphological disparity of lophotrochozoan phyla makes it difficult to predict the morphology of the last common ancestor. Only fossils of stem groups can help discover the morphological transitions that o...

Ancestral echinoderms from the Chengjiang deposits of China
Deuterostomes are a remarkably diverse super-phylum, including not only the chordates (to which we belong) but groups as disparate as the echinoderms and the hemichordates. The phylogeny of deuterostomes is no...

Head and backbone of the Early Cambrian vertebrate Haikouichthys
Agnathan fish hold a key position in vertebrate evolution, especially regarding the origin of the head and neural-crest-derived tissue1. In contrast to amphioxus2, lampreys and other vertebrates possess a complex...

Primitive deuterostomes from the Chengjiang Lagerstätte (Lower Cambrian, China)
Cambrian fossil-Lagerstätten (sites of exceptional fossil preservation), such as those from Chengjiang (Lower Cambrian) and the Burgess Shale (Middle Cambrian), provide our best window into the Cambrian ‘explo...
