Very excited to visit Flowers Cove in Newfoundland, famous for its Thrombolites, fossils of organisms more than 650 million years old. Incredibly rare, with these large examples only here or in Western Australia. Created when microorganisms photosynthesised their food #thrombolite #flowerscove

Thrombolite Walking Trail in Flowers Cove
The site of the fossilized remains of some of Earth’s earliest primitive, microbial life forms.

The classic site, but hardly alone. There are massive subtidal examples in the tidal channels of the Bahamas, for instance. I used to take students to see a modern freshwater thrombolite reef (stromes with an internally clotted texture) in a lake in central NY.

The earliest reef builders were microbes, but the first multicenular reefs builders were made by archaeocyath sponges and a creature resembling a stack of ice cream cones called Cloudina. ⚒️ | 🧪 | #Reefs

Thrombolite Walking Trail in Flowers Cove, Newfoundland and Labrador
Thrombolite Walking Trail in Flowers Cove, Newfoundland and Labrador
The tiny town of Flower’s Cove on Newfoundland’s Great Northern Peninsula is one of only two places in the world where the fossilized remains of some of the Earth’s oldest and most primitive life forms can be found. Lining the shoreline of this tiny saltwater Cove are thrombolites — gray, bun-shaped rock formations estimated to be 650-million-years-old. Their name means “clotted structure.” Thrombolites are thought to be the planet’s first living creatures to release free oxygen, and they predate dinosaurs by at least 225 million years. The thrombolytic formations are about three to four meters in diameter. Although some have broken over time, most have a circular center surrounded by pie-shaped wedges. Often described as “living rocks,” they were created by prehistoric unicellular microorganisms depositing layers of calcium carbonate leached from the surrounding water. The results were solid grey structures resembling flattened boulders. Interspersed among the formations are glacial erratics, darker-colored round rocks deposited by the Pleistocene glacier.  The thrombolites’ surfaces have a faint, irregular print or pattern, and lichens adhere in random spots. The furrows etched into the surfaces might be drainage channels or cracks caused by the ebbing and flowing of tides. The larger thrombolites may be several amalgamated communities. Some of the younger thrombolites have burrowing tunnels made by prehistoric metazoan organisms.  The thrombolites can be reached from a short walking trail after crossing the picturesque red and white wooden “Marjorie’s Bridge” via a boardwalk. Across the bay to the south is another large collection of the formations.

Amazing. So, prebiotic or prior to the great L v R showdown? try again to find a chondorite thrombolite

They’re living rocks. Bill Bryson wrote about the stromatolites (a type of thrombolite) in his book Down Under, appreciating them as "living fossils" with a profound history, and noting their importance for understanding early life on Earth. It’s so cool right?
