🧪⚒️ Stromatolites can still grow in very salty waters; too salty for the organisms that outcompete them everywhere else. The last outposts of a form of life that, for a billion years or three, dominated the planet.
Growing up, I’d always heard that the last living Stromatolites — aka one of the most archaic organisms on earth—could only be found in a single isolated bit of Australian coastline.
Imagine my shock at learning there’s a colony in Utah’s Great Salt Lake!?
