Modular skeletons from the Mural Formation (late early Cambrian), Canadian Rocky Mountains: possible hypercalcified sponges Open
Macroscopic, modular, morphologically simple skeletons occur in the uppermost Mural Formation (Cambrian, Epoch 2, Bonnia – Olenellus Biozone), west-central Alberta and adjacent east-central British Columbia. They represent organisms that l…

Continental-scale drainage reorganization during Mesoproterozoic orogenesis: Evidence from the Belt Basin of western North America Open
The Mesoproterozoic Belt Basin of the northwestern United States and southwestern Canada contains a 5–20-km-thick metasedimentary succession deposited during an important transition in the Precambrian development of North America. Key unre…

Comment on “Ultrastructure reveals ancestral vertebrate pharyngeal skeleton in yunnanozoans” Open
Tian et al . (Reports, 8 July 2022, p. 218) claim that Cambrian yunnanozoan animals are stem vertebrates, based partly on their observation at the nanometer scale of microfibrillar tissue located in the branchial arches. They interpret thi…
