Fossilized stromatolites – a type of layered rock made up of microbial mats of microorganisms – dating back to over 3.5 million years ago contain evidence of cyanobacteria activity.
Are Sharks older than alligators?
The University of Florida research shows the American alligator is much older than humans, who only are a few hundred-thousand years old. Lead researcher Evan Whiting says only a few sharks and other species are as old as alligators. … Florida is the only place on Earth where alligators and crocodiles live side-by-side.
