Cincinnatian Collectors from the myFOSSIL app 5 years, 3 months ago 5 years, 3 months ago5 years, 3 months agoSmall bit of sediment with nice sized graptolites in it! I think this was collected from the Kope Formation. Can anyone confirm? Found the specimen in a backpack of mine with no associated information… must have been a last minute find! #fossil
What is a graptolite?? It’s a new creature for me!
Great question! These are microorganisms that live in colonies (the black saw-toothed object) and float around in the ocean feeding on particles in the water. They have a notochord like structure – notochords are one of the defining characters of vertebrates but these guys lack a vertebral column and other vert characteristics.
