For example, Upper Oligocene sediments of Baja California Sur yield a diversity of baleen-bearing mysticetes (Barnes, 1998, 1999, 2002), and lowermost Miocene sediments in Baja California Sur have yielded baleen-bearing mysticetes of moderate size (Gonzalez-Barba et al.
01) and Mysticetes had a higher mean prevalence of the barnacle than Odontocetes (5.
Coronulid whale barnacles did not appear in the fossil record until approximately 23 million years ago (Newman and Ross, 1976; Seilacher, 2005), after the appearance of Mysticetes and Odontocetes in the fossil record approximately 35 million years ago.
Unlike other arctic mysticetes, bowheads float when they are killed, and so can be recovered and flensed immediately as long as the animal does not escape under ice.
Paleontologists have long thought that Mysticetes and Odontocetes represent separate evolutionary lines that split from a group of ancestral toothed whales some 40 million years ago.
The new findings suggest that Odontocetes and Mysticetes are not true evolutionary lines.
Scientists have long thought that Blues and other baleen whales, which belong to a suborder called Mysticetes, evolved millions of years ago from ancestral toothed whales, but they have lacked detailed fossil evidence to chronicle the transition from teeth to baleen.
In later years, especially in the North Pacific, when the number of baleen whales caught represented a small proportion of the total catch (relative to sperm whales, the primary target) these occasional mysticetes would be processed together with sperm whales for bone-meal and industrial oil.
When whaling was almost done with mysticetes in the North Pacific, a widespread style of catching occurred which was ruinous for baleen whales; the main point of this was as follows.
Gray whales are unique among mysticetes in that they suction sediment and benthic organisms (e.
