New biomarker found in Maoming Basin

Two novel isomeric decamethylhenicosanes (C31 hydrocarbons) were newly identified as a new biomarker class for B. brawnii in Liao et al. (2018).

These hydrocarbons have additional methyl groups on the isoprenoid chains.

It seems to be unstable especially for C-C bonds between 2-3, 6-7, 15-16, and 19-20.

Therefore it would not be preserved in thermally matured rocks, but it would be compounds of interest for immatured samples.
