There have been recent efforts by various teams of researchers to find out how many of the thousands of prehistoric and ancient organisms are still alive today.
The subject of their research varies greatly, from analyzing tooth enamel from fossil teeth, to analyzing proteins from specimens as old as 40 million years old. While a lot of progress has been made lately with respect to how we look for, and find, fossils, and with the ability of computers to store and retrieve vast amounts of information, there is still a long way to go when it comes to discovering the actual survival rate of these organisms.
One of the teams that has been researching this question, and attempting to use modern technology, is the Museum of paleontology at London’s Natural History Museum. Their recent press release states: “We’ve discovered an astonishing array of fossils in two types of rocks. The fossils were previously thought to be beyond recognition. They reveal a previously unknown planet in our Solar System which has oceans, rivers and seas – as well as dinosaurs.”
