Dense biological communities of large epifaunal taxa similar to those found along ridge crest vents at the East Pacific Rise were discovered in the abyssal Gulf of Mexico. These assemblages occur on a passive continental margin at the base of the Florida Escarpment, the interface between the relatively impermeable hemipelagic clays of the distal Mississippi Fan and the jointed Cretaceous limestone of the Florida Platform. The fauna apparently is nourished by sulfide rich hypersaline waters… 

Taphonomic Signature of Petroleum Seep Assemblages on the Louisiana Upper Continental Slope: Recognition of Autochthonous Shell Beds in the Fossil Record

Chemoautotrophically-based benthic communities on the Louisiana continental slope are currently producing the only significant localized, autochthonous shell accumulation in the northern Gulf of

Vent-type taxa in a hydrocarbon seep region on the Louisiana slope

Recent discoveries on the northern Gulf of Mexico continental slope have altered our understanding of biological and chemical processes occurring in the deep ocean. A biological community of

The ecology of Atlantic vents differs from the ecology of Pacific vents in ways that highlight aspects of biogeography, trophic ecology and sensory adaptations.

Eocene deep-sea communities in localized limestones formed by subduction-related methane seeps, southwestern Washington

Densely populated communities of soft-bottom-dwelling taxa similar to those found today along subduction zones off the coasts of Japan and Oregon have been discovered in very localized deep-water

Hydrothermal Vent Animals: Distribution and Biology

There are similarities in the animal distributions at vent communities from 20�S to 46�N on the Mid-Ocean Ridge in the Pacific Ocean and at cold sulfide seeps in the Gulf of Mexico.

Fossil chemosynthetic communities related to vents or seeps in sedimentary basins : the pseudobioherms of southeastern France compared to other world examples

The term pseudobioherm is used for fossiliferous calcareous bodies with a bioherm-like shape but neither built by organisms, nor bulging at the sediment/water interface. Jurassic pseudobioherms of

Notes on Fauna from Several Deep-Sea Hydrothermal Vent and Cold Seep Soft-Sediment Communities

Since our initial summary of the macrofauna of hydrothermal soft sediments of Guaymas Basin and the Galapagos Mounds (Grassle et al., 1985), we have obtained cores from other hydrothermal vent and

Fossil clams from a serpentinite‐hosted sedimented vent field near the active smoker complex Rainbow, MAR, 36°13′N: Insight into the biogeography of vent fauna

Hydrothermal circulation at ultramafic‐hosted sites supports a large variety of high‐ and low‐temperature hydrothermal vents and associated ecosystems. The discovery of abundant fossil vesicomyid and

Cretaceous Cold-Seep Communities and Methane-Derived Carbonates in the Canadian Arctic

Lower Cretaceous cold-seep fossil assemblages have been found in the Canadian Arctic Archipelago. Serpulid worm tubes and bivalves are most abundant in these communities; in contrast, fossils are
