Dinosterane is a steroidal alkane, also known as 4α,23,24-trimethylcholestane.^[1] It is used in geochemistry as a biomarker, interpreted as an indication of dinoflagellate presence^[2] due to its derivative dinosterol high occurrence in extant dinoflagellate species^[3] and its rarity in other taxa,^[1] although it has been shown to be produced by a single species of marine diatom as well.^[2]
