Triaromatic steroid hydrocarbons bearing a methyl substituent at position 2, 3, or 6 have been identified in marine sediments and petroleums from the Paris basin by comparison with C21 (1,2, 3), C27 (4) and C29 (5) synthetic standards. Due to their formation with depth they are useful for maturity studies
