And, finally, I've restored a Jurassic reef dominated by the red alga Solenopora jurassica. We've known about the pink/red colouring of this species for 145 years, but it's seldom seen in #paleoart! Head to www.patreon.com/c/markwitton for more context, as well as heaps of other content!

This month on my #Patreon, I've been uploading and discussing #paleoart inspired by ancient microbes and photosynthetic organisms with known (or predicted) colour data. There's some amazing #sciart inspiration out there, like hypothesised bacteria that turned Early Archean seas purple... (1/4)
