A strong odor called "smell of sulfur" actually is given off by several sulfur compounds, such as hydrogen sulfide and organosulfur compounds. Source: Internet
Another hypothesis involves ocean venting of hydrogen sulfide gas. Source: Internet
Anoxia seeAlso Evidence for widespread ocean anoxia (severe deficiency of oxygen) and euxinia (presence of hydrogen sulfide ) is found from the Late Permian to the Early Triassic. Source: Internet
Finally, sulfophilic bacteria reduce the bones releasing hydrogen sulfide enabling the growth of chemoautotrophic organisms, which in turn, support organisms such as mussels, clams, limpets and sea snails. Source: Internet
Hydrogen sulfide emissions A severe anoxic event at the end of the Permian would have allowed sulfate-reducing bacteria to thrive, causing the production of large amounts of hydrogen sulfide in the anoxic ocean. Source: Internet
