Rhynchonelliformea Brachiopoda is one of the most well-documented and studied groups of invertebrate organisms in the fossil record, but the current lack of standardized methods for comprehensive analyses of shell shape allows for important aspects of brachiopod life to be disregarded. Context dependent studies that are taxonomically, temporally, o...

Methane seeps were a common feature in the Late Cretaceous Western Interior Seaway of the United States. We document the occurrence of methane seep deposits in the Pierre Shale on the Cedar Creek Anticline in east‐central Montana for the first time. The seep deposits occur in the lowermost part of the Baculites baculus Zone (the Endocostea typica Z...

Brachiopod shell morphology is well characterized descriptively based on valve shapes, but is poorly integrated in a scheme that allows for quantitative comparison across disparate forms. A focus on overall variation of valve morphology, independent of taxonomic classification, provides an avenue to define a morpho-ecospace and relative disparity w...

During the Late Cretaceous most of North America was covered in a broad, shallow epicontinental seaway (the Western Interior Seaway) littered with cold-methane seeps. These unique environments were most common during the middle and late Campanian time period and are concentrated in the northern part of the seaway in modern Montana, Wyoming, and Sou...
