In Depth
Although only known from teeth, these have confirmed that Kogiopsis is an extinct sperm whale. The teeth of Kogiopsis had crowns that were between three and five centimetres long, and may have been used against other marine mammals such as smaller whales. The teeth of Kogiopsis are often available to buy through fossil dealers.
