Baleen - Wikipedia, the free encyclopedia |
 | | This is indicated by skull modifications which are associated with baleen (such as a buttress of bone found beneath the eyes in the upper jaw, and loose lower jaw bones at the chin), being found in fossils from considerably earlier. |
 | | Currently, baleen is believed to have evolved around thirty million years ago, possibly from a creature with a hard, gummy upper jaw, similar to that found on Dall's porpoise today, which are, at a microscopic level, almost identical to baleen. |
 | | Baleen plate was formerly used in buggy whips and parasol ribs, and to stiffen parts of women's stays and dresses, like corsets. |
