The duo was studying the shell of a specimen previously discovered by other researchers.
And during the course of their studies, they were examining its chemical composition.
This process involved collecting samples along the length of the shell at intervals of 50 cm.
And they also tested the oxygen and carbon isotopes along the shell to learn more about how long it lived.
They found repeated isotope signatures during this procedure, which suggest it derives from methane released into the water from the sea floor each year.
