Whale songs and war: The less talked-about climate impacts 2018-12-01T05:00:00Z They called Maiabalaena, meaning “mother whale,” a surprising intermediate evolutionary stage between modern baleen whales and their toothed ancestors. Ancient toothless whale was forerunner of modern cetacean giants 2018-11-29T05:00:00Z Modern baleen whales feed by filtering gulps of seawater through plates of baleen in their mouths.Credit: Toothless whale fossil fills gap in filter-feeding evolution 2018-10-17T04:00:00Z To address that quandary, the team looked at the baleen samples’ makeup of protein-building amino acids, which correlate to specific background environmental conditions or prey. To See Where a Whale Has Been, Look in Its Mouth 2021-12-08T05:00:00Z Another hypothesis posits that for a time, whales fed using both teeth and baleen.

CO2 is killing the ocean, too 2018-09-13T04:00:00Z The oldest direct fossil evidence of baleen dates from 11 million years ago, but scientists suspect the first whales with baleen appeared about 23 million years ago. Ancient toothless whale was forerunner of modern cetacean giants 2018-11-29T05:00:00Z Some ancient ancestors of giant baleen whales did not filter their food through plates of hair-like bristles like their modern kin. Toothless whale fossil fills gap in filter-feeding evolution 2018-10-17T04:00:00Z They found the dietary preference of each species remained stable throughout each baleen sample, making it likely that nitrogen fluctuations resulted from the animals’ annual voyages throughout the Atlantic Ocean. To See Where a Whale Has Been, Look in Its Mouth 2021-12-08T05:00:00Z They found neither teeth nor the bone structure needed to support baleen—a significant discovery in itself.

Paleo Profile: The Sand Whale 2017-11-25T05:00:00Z For years, scientists have disagreed about which species of baleen whale came first, and how the toothless species were related. Baleen Whales Intermingled as They Evolved, and Share DNA With Distant Cousins 2018-04-04T04:00:00Z Until recently, scientists have known very little about precisely when the first baleen whales evolved. Prehistoric Toothless Whale Among Oldest of Its Kind 2018-04-19T04:00:00Z They were also prized for their long plates of baleen, which acts as a strainer to scoop up small fish and crustaceans, and was used for buggy whips and women’s corsets. UW research: Listen to the ‘crazy, crazy’ songs of bowhead whales 2018-04-03T04:00:00Z The other was that whales started filter feeding before they lost their teeth, perhaps even using their dentition and baleen in tandem before the switch. Paleo Profile: The Crown Tooth 2017-07-16T04:00:00Z The whale then spits the water back out through plates of baleen that filter out the tiny prey.

Baleen Whales Intermingled as They Evolved, and Share DNA With Distant Cousins 2018-04-04T04:00:00Z “But right now, it anchors the modern baleen whale lineage to at least 27.5 million years.” Prehistoric Toothless Whale Among Oldest of Its Kind 2018-04-19T04:00:00Z Hopefully, that will help scientists better understand when baleen first appeared and how filter feed developed. 30-million-year-old whale provides insight into how modern whales began filter feeding 2017-06-29T04:00:00Z What sort of organism?: A cetacean related to today's baleen whales. Paleo Profile: The Crown Tooth 2017-07-16T04:00:00Z There are not many evolutionary journeys that can rival this, but that made by the descendants of some small, terrestrial mammals, which turned into the gargantuan aquatic krill-eaters called baleen whales, is one such. How whales started filtering food from the sea 2017-06-29T04:00:00Z Yet, Lambert and coauthors write, specific features of the skull identify Mystacodon as the earliest known baleen whale. New Fossil Fills In Missing Moment in Baleen Whale History 2017-06-18T04:00:00Z But some later lost their teeth, developing plates of bristle-like baleen in their mouths that’s used to filter small prey such as krill from the water. Prehistoric Toothless Whale Among Oldest of Its Kind 2018-04-19T04:00:00Z Coronodon isn’t the oldest such ancestor, but it does provide a new evolutionary link between the modern baleen whale and the group of toothed whales from which they are descended, known as archaeocetes. 30-million-year-old whale provides insight into how modern whales began filter feeding 2017-06-29T04:00:00Z One line of argument suggested that ancestral baleen whales were suction feeders and that this led to the loss of teeth and the subsequent evolution of baleen. Paleo Profile: The Crown Tooth 2017-07-16T04:00:00Z Some researchers theorise that suction-filter feeding in whales began with teeth that could be gnashed together to form a simple sieve, and that only subsequently were these teeth replaced by baleen. How whales started filtering food from the sea 2017-06-29T04:00:00Z This cetacean is an anatomical bridge between more archaic forms like Basilosaurus and the profusion of baleen whales that followed.

How did whales become so large? Scientists dive into marine mystery 2017-05-24T04:00:00Z For millions of years afterward, most baleen whales remained about 15 feet long. How did whales get so big? Paleontologists say they’ve figured it out. 2017-05-25T04:00:00Z The researchers suspected that an environmental change happened during that time that essentially caused the baleen whales to bulk up. How Whales Became the Biggest Animals on the Planet 2017-05-24T04:00:00Z Baleen is a relatively recent specialization, in other words, and some fossils even seem to document how ancient baleen whales used teeth and baleen in combination before switching to baleen only. New Fossil Fills In Missing Moment in Baleen Whale History 2017-06-18T04:00:00Z But the study authors suggest that early baleen whales like Toipahautea were generalists that used a variety of feeding styles. Prehistoric Toothless Whale Among Oldest of Its Kind 2018-04-19T04:00:00Z That, says Slater, drove the evolution of gigantism in baleen whales. How did whales become so large? Scientists dive into marine mystery 2017-05-24T04:00:00Z But 3 million years in the past, the scientists reported Tuesday in the Proceedings of the Royal Society B, baleen whales underwent a dramatic size shift.
