In Britain and the United States, paleontologists found out that large fish lived during the Cretaceous Period and swam through the earth’s seas. These large fish would eat plankton and had filters for this process. These large fish were similar to current humpback and baleen whales. Fossils have been discovered of these fish that have dated back to 145 million years ago. There was a time period between 145 million years ago and 60 million years ago where the fish seemed to be extinct. This weird extinction puzzled scientists until last year when Matt Friedman, a University of Oxford paleontologist discovered a 15 foot long fossil fish. The fish was found in Kansas. It was located in a piece of rock. The fish was similar to the filter feeding, plankton eating fish. It dated back to 75 million years ago, when they were previously thought to be extinct. Friedman says that the fish were a hidden dynasty.
