Among the baleen whales found, the most common was an undescribed species of cetotheriid whale measuring around 5 to 8 m (16 to 26 ft), and most of the other baleen whales found were roughly the same size. Toothed whale remains found consist of beaked whales (such as Messapicetus gregarius), ancient pontoporiids (such as Brachydelphis mazeasi ...
• Physical maturity for female sperm whales is around 10.6 to 11 meters (35 to 36 ft) on average, whilst for male sperm whales, it is around 15 to 16 meters (49 to 52 ft) in length.

[ 15 ] [ 60 ] [ 61 ] The extinct whale species Perucetus colossus was shorter than the blue whale, at 17.0–20.1 meters (55.8–65.9 ft) but it is estimated to have rivaled or ...
