Working on the isotopic signature of Jutrassic organic matter, we got an
unknown referee that states that during the Jurassic terrestrial organic
matter was heavier (more positive) than marine organic matter.
So far the literature we know says the contrary.
Can anybody enlighten us on this controversy?
Thanks
