High-resolution Early Triassic ammonoid biostratigraphy of South Tibet, China and implications for global correlations
Ammonoids are key fossil indexes for Triassic biochronology, as all Triassic stages and
substages were initially defined on ammonoid faunas. In recent decades, the temporal …

Orthoceratoid and coleoid cephalopods from the Middle Triassic of Switzerland with an updated taxonomic framework for Triassic Orthoceratoidea
Orthoconic cephalopods are subordinate, but persistent, widespread and regionally
abundant components of Triassic marine ecosystems. Here, we describe unpublished …

Toward an understanding of cosmopolitanism in deep time: a case study of ammonoids from the middle Permian to the Middle Triassic
Cosmopolitanism occurred recurrently during the geologic past, especially after mass
extinctions, but the underlying mechanisms remain poorly known. Three theoretical models …
