“…Cretaceous fossil cold-seep faunas are often viewed as analogues for modern cold-seep communities despite significant differences in taxonomic composition and in environmental conditions, including water depth and sulfide concentrations (Beauchamp and Savard 1992; Powell et al 1998; Callender and Powell 1999; Kiel 2015; Meehan and Landman 2016). Some of the major clades of chemosymbiotic invertebrates that occupy cold-seeps today likely did not originate until the early Cenozoic, ecologically important Cretaceous taxa such as ammonites have gone extinct, and major changes in the composition of cold-seep communities occurred after the Cretaceous as seawater sulfide availability increased (Vrijenhoek 2013; Kiel 2015).…”

“…In later stages of seep development, lithification of the sediment hindered the settlement of infaunal seep taxa and facilitated colonization by epifaunal taxa such as serpulid tubeworms. In the Pierre Shale of the WIS, baculitid ammonites, inoceramids, and lucinids, which also commonly occur outside seep settings, dominate seep assemblages, but the seep assemblages vary in the relative abundance and diversity of secondary organisms that attach to exposed potions of the carbonate cap, reflective of changing substrate conditions at the seep over its lifetime (Meehan and Landman 2016).…”

Accurately recognizing analogues between fossil and modern ecosystems allows paleoecologists to more fully interpret fossil assemblages and modern ecologists to leverage the fossil record to address long-term ecological and environmental changes. However, this becomes increasingly difficult as taxonomic turnover increases the dissimilarity between ecosystems. Here we use a guild-based approach to compare the ecological similarity of Cretaceous cold-seep assemblages preserved in the Pierre Shale surrounding the Black Hills and modern cold-seep assemblages from five previously recognized biofacies. We modify modern assemblage data to include only those taxa with fossilizable hard parts greater than 5 mm in length to make these modern data sets more comparable to potential fossil analogues. We find that while the Black Hills assemblages are more similar in ecological guild composition to the modern thyasirid biofacies, subsets share similarities in ecological structure to the lucinid and mussel-bed biofacies. The fossil seep assemblages are also more similar to one another than are modern assemblages belonging to the same biofacies, despite greater geographic and temporal dissimilarity among the fossil samples. Furthermore, guild-level ordination analyses show a secondary faunal gradient that reflects community succession in the hard substrate–dominated modern assemblages and reveals a parallel faunal gradient in the soft sediment–dominated Cretaceous assemblages, consistent with a gradient in the influence of seep fluids on the faunas. Thus, while the Black Hills assemblages are quite homogeneous in their composition, they capture ecological variation similar to successional patterns in modern seep systems.

“…The lithology of ancient seeps has been described by a number of authors (Kauffmann et al, 1996; Metz, 2008; Hendricks et al, 2011). Using the seep structure model of Handle (2014), Meehan and Landman (2016) related faunal expressions to seep architecture, with variation among seep occurrences resulting from variation among causal factors of original depth, lateral extent of seepage, methane flux, oxygen levels, water temperature (Levin, 2005), seep longevity (Larson et al, 2014), and perhaps as yet unrecognized factors; additional work is needed.…”

Betelgeusia brezinai new species (Radiasteridae, Paxillosida, Asteroidea) is described from diversely fossiliferous Upper Cretaceous methane seep deposits of South Dakota. Asteroids are rare at modern chemosynthetic settings, although a hydrothermal vent occurrence is known, and two possible fossil methane seep occurrences have been reported. The Radiasteridae is important to the interpretation of crown-group asteroid phylogeny. Two extant genera are assigned to the family: Radiaster is known from relatively few but geographically widely dispersed largely deeper-water settings, and Gephyreaster is uncommon over a range of depths in the North Pacific Ocean. Jurassic and Cretaceous radiasterids have been described from geographically widely separated localities. In morphological-based phylogenetic analyses, the Radiasteridae has been assigned to the order Paxillosida, and Gephyreaster is similarly placed in a molecular evaluation; Radiaster has not yet been treated in a molecular study. In molecular treatment, an approximately traditional Paxillosida is a sister taxon to a significant part of the traditional Valvatida. Comparative morphology of Mesozoic and extant asteroids enables a hypothesis for a stemward, Mesozoic paxillosidan.
