The kentriodontid and squalodelphinid dolphins in Switzerland

Researchers from Switzerland’s University of Zurich recently discovered «two families of dolphins previously unknown in Switzerland.» The researchers studied ear bones from roughly 300 fossils of dolphins and whales from this period, according the study, which was published in the journal PeerJ in May 2022.

They discovered that the kentriodontid dolphin and squalodelphinid dolphin both swam in Switzerland’s waters about 20 million years ago, in an ocean located in the Swiss Plateau region.

Switzerland is now a landlocked country, yet millions of years ago, the country was «part of an island landscape,» according to CBS News. While these archaic dolphins no longer swim in Switzerland, their finding is nevertheless amazing.
