The Peel Sound Formation (Devonian) of Prince of Wales and Adjacent Islands: <i>A Preliminary Report</i>

Аннотация

Reports 1966-67 summer work in a long-range study by a Univ of Ottawa group. Discrete transitions between the laterally equivalent redbed-sandstone-carbonate facies of the Peel Sound Formation were revealed and evidence is strengthened of the role of fluvial, lagoonal and marine environments, controlled by movements of the Boothia Arch, in this sequence. Vertebrate faunas found mainly in large but isolate faunules include cyathaspidids, pteraspidids, heterostraci, osteostraci, athrodires, and a few osteichthyes; they appear to be equivalent to fauna of Downtonian and Dittonian stages.
