The Atlantic gray whale Eschrichtius robustus presents an interesting case study of climate related dispersal and extinction. While limited fossil records confirm its presence in the Atlantic up until the 18th Century, its abundance and distribution within the Eastern and Western basins are still not well understood. The discovery of presumed gray whale fossil remains from the Georgia Bight and the Atlantic coast of Florida, from the mids to lates, provides a new opportunity to recover additional data regarding their chronology within the Western basin.

Material Details

The gray whale now exists only in the North Pacific Ocean, but surprisingly the species was first described from subfossil remains discovered on European coasts. These data together with a similar range of dates for specimens from the western North Atlantic as well as limited historical records, support the view that the gray whale existed in the Atlantic Ocean until the 17th century.

The populations on both sides of the North Atlantic apparently declined during a period of active coastal whaling, supporting the suggestion that it was extirpated by early whalers. Most users should sign in with their email address.

A newly discovered fossil whale represents a new species and an important step in the evolution of whale locomotion, according to a study published December 11, in the open-access journal PLOS ONE by Philip Gingerich of the University of Michigan and colleagues. The fossil record of whale evolution tracks the transition from land-dwelling ancestors to ocean-dwelling cetaceans. Protocetids are a group of early whales known from the Eocene Epoch of Africa, Asia, and the Americas.

While modern whales are fully aquatic and use their tails to propel themselves through the water, most protocetids are thought to have been semi-aquatic and swam mainly with their limbs. In this study, Gingerich and colleagues describe a new genus and species of protocetid, Aegicetus gehennae. It is the youngest-known protocetid, dating to around 35 million years ago, and is known from one exceptionally complete skeleton and a partial second specimen, making it among the best-preserved ancient whales.

Compared with earlier whales, it has a more elongated body and tail, smaller back legs, and lacks a firm connection between the hind legs and the spinal column. These adaptations indicate an animal that was more fully aquatic and less of a foot-powered swimmer than its ancestors. The body shape of Aegicetus is similar to that of other ancient whales of its time, such as the famous Basilosaurus. These animals appear to be well-adapted for swimming through undulation of the mid-body and the tail, somewhat as crocodiles swim today.

The authors suggest that an undulatory swimming style might represent a transitional stage between the foot-powered swimming of early whales and the tail-powered swimming of modern whales. The authors add: “Early protocetid whales living 47 to 41 million years ago were foot-powered swimmers, and later basilosaurid and modern whales — starting about 37 million years ago — were tail-powered swimmers.

The oldest published reports of white killer whales date back to the early 20th century e. A summary of published sightings of white killer whales in the North Pacific is shown in Table 1. Comparatively fewer reports of white killer whales have been made from other oceans, including accounts from around New Zealand in and the Azores in cited in Fertl et al. Herein, we report the recent sightings of white killer whales in the western North Pacific and discuss the possible implications of their occurrence.

Whale Watching

Wadi Al-Hitan, Whale Valley, in the Western Desert of Egypt, contains invaluable fossil remains of the earliest, and now extinct, suborder of whales, Archaeoceti. These fossils represent one of the major stories of evolution: the emergence of the whale as an ocean-going mammal from a previous life as a land-based animal. This is the most important site in the world for the demonstration of this stage of evolution.

It portrays vividly the form and life of these whales during their transition. The number, concentration and quality of such fossils here is unique, as is their accessibility and setting in an attractive and protected landscape. The fossils of Al-Hitan show the youngest archaeocetes, in the last stages of losing their hind limbs.

The overall goal of the CMP is to protect habitat for the population, and minimise anthropogenic threats to maximise population recovery. Progress to date.

Baleen whales are the largest animals on Earth, a remarkable example of evolutionary adaptation and key ecosystem engineers. They owe their success to filter feeding, but when and how this strategy emerged remains a central question in marine mammal evolution. Baleen whales, or mysticetes, have an unusual way of feeding. Without teeth, they rely on baleen — a comb-like sieve made of the protein keratin — to filter vast quantities of small prey directly from seawater.

How and when whales evolved this filter feeding continues to be a mystery. Like all mammals, the earliest whales had teeth, and some of them were fearsome predators. The emergence of modern baleen whales from these ancient raptorial forms is one of the most striking evolutionary transitions in the history of mammals, with enormous implications for global ocean ecology. To address this problem, project partners created a comprehensive data set on the anatomy of living and extinct mysticetes, reconstructed their evolutionary relationships, and used detailed observations on the feeding behaviour and anatomy of whales, dolphins and seals to understand how ancient baleen whales fed.

Lastly, they synthesised the results to trace the gradual emergence of filter feeding among early whales. How did whales transition from biting prey with teeth to filter feeding? It was previously thought that baleen first appeared in a family of extinct whales that still had teeth, and that those early forms were capable of both biting larger prey and filter feeding. Researchers showed that this was probably not the case. Instead, ancient mysticetes had teeth as sharp as those of lions and caught their prey by using a combination of biting and suction.

Baleen and filter feeding evolved only later, after these early whales had almost lost their teeth.

Reports of whale sightings by aerial survey platforms, whale watch vessels, and fishing vessels are e-mailed, faxed, or phoned into the Maine Whale Sightings Hotline and then entered into a database maintained by DMR staff in Boothbay. Immediately after entry, the sightings reports are available to fishermen and the general public via an Internet mapping application. The website, developed by Northern Geomantics of Hallowell, Maine, uses the latest Internet Mapping System IMS technology to display historical and contemporary locations of Right whales and other species on a detailed, interactive map.

It is designed to allow interested parties from a variety of user groups to view and interact with Geographic Information Systems GIS data pertaining to whales in the State of Maine waters and beyond. The site allows users to view information about large whales, such as location, species and their distribution relative to bathymetry, and other geographic features.

This in itself is a rare find, as many fossils are poorly preserved when they are unearthed. The discovery of another partial skeleton allowed the team to verify their new species. This suggests it was a swimmer who could not hold its own weight on land. It was definitely less of a foot-powered swimmer than its ancestors. It will also generate new ideas about how these mammals became increasingly adapted for moving efficiently in the water.

Sperm whales Physeter macrocephalus socialize in the Indian Ocean. Colby Oxford University Press Ecological connections between species form a tangled web. Intentional perturbations can lead to unintended consequences, or even shift an ecosystem from one state into another. With the human population soaring towards 8 billion — consuming, polluting and emitting as it grows — oceans face unprecedented challenges, as do their denizens.

Nearly 3 million whales were killed in the twentieth century; the animals must now negotiate hazards such as ship strikes and noise. And global harvests of ocean fish by humans have hit 1 trillion a year. Now, three books — by palaeobiologist Nick Pyenson, eminent krill scientist Stephen Nicol and historian Jason Colby — explore oceans from the perspectives of whales and krill across palaeontological, decadal and even annual timescales.

The author — curator of fossil marine mammals at the Smithsonian Institution in Washington DC — takes us to field sites from Antarctica to Alaska. His narrative captures the excitement of suction-cup tagging of humpback whales, and of digs in Panama, seeking answers to deep questions in cetacean science. Pyenson likens palaeontology to astronomy for its capacity to transport us in imagination to places never experienced. At Cerro Ballena in northern Chile, he uncovers the densest fossil-whale site yet found, with bones dating to between 6 million and 9 million years ago.
