Red Alga Pigments Stand The Test Of Time

Boron-containing organic pigments are responsible for the color of a fossilized Jurassic-period red alga
Department: Science & Technology
Keywords: fossils, pigments, boron, Jurassic, red algae

An unusual class of boron-containing organic pigments, dubbed borolithochromes, is responsible for the pink color of a fossilized Jurassic-period red alga, scientists propose (Proc. Natl. Acad. Sci. USA, DOI: 10.1073/pnas.1007973107). Because the pigments are found only in the algae and not in the surrounding limestone, it is assumed that they were produced by the algae and not by some later transformation in the rock.
