FOSSILS OF THE NORTH SEA

A lovely 12 cm creamy orange Bottlenose Dolphin, Tursiops sp. lumbar vertebrae found in the Brown Bank area of the North Sea, one of the busiest seaways in the world.

Bottlenose dolphins first appeared during the Miocene and swam the shallow seas of this region. We still find them today in warm and temperate seas worldwide though unlike narwhal, beluga and bowhead whales, Bottlenose dolphins avoid the Arctic and Antarctic Circle regions. 

Their name derives from the Latin tursio (dolphin) and truncatus for their characteristic truncated teeth

We find their remains in the sediments of the North Sea. There are two known fossil species from Italy that include Tursiops osennae (late Miocene to early Pliocene) from the Piacenzian coastal mudstone, and Tursiops miocaenus (Miocene) from the Burdigalian marine sandstone.

Many waterworn vertebrae from the Harbour Porpoise Phocoena sp., (Cuvier, 1816), Bottlenose dolphin Tursiops sp. (Gervais, 1855), and Beluga Whale, Delphinapterus sp. (Lacépède‎, 1804‎) are found by fishermen as they dredge the bottom of the Brown Bank, one of the deepest sections of the North Sea.  

The North Sea is a sea of the Atlantic Ocean located between the United Kingdom, Denmark, Norway, Germany, the Netherlands, Belgium and France. An epeiric sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north.

The fishermen use small mesh trawl nets that tend to scoop up harder bits from the bottom. This technique is one of the only ways this Pleistocene and other more recent material is recovered from the seabed, making them relatively uncommon. The most profitable region for fossil mammal material is in the Brown Bank area of the North Sea. I've circled this area on the map below to give you an idea of the region.

Brown Bank, North Sea, Pleistocene Dredging Area

In May 2019, an 11-day expedition by European scientists from Belgium and the United Kingdom was undertaken to explore three sites of potential geologic and archaeologic interest in the southern North Sea. 

It has long been suspected that the southern North Sea plain may have been home to thousands of people, and chance finds by fishermen over many decades support this theory. 

A concentration of archaeological material, including worked bone, stone and human remains, has been found within the area around the Brown Bank, roughly 100 km due east from Great Yarmouth and 80 km west of the Dutch coast. The quantities of material strongly suggest the presence of a prehistoric settlement. As such the Brown Bank provides archaeologists with a unique opportunity to locate a prehistoric settlement in the deeper and more remote areas of the North Sea, known today as Doggerland.

Until sea levels rose at the end of the last Ice Age, between 8-10,000 years ago, an area of land connected Great Britain to Scandinavia and the continent.  It has long been suspected that the southern North Sea plain was home to thousands of people, and chance finds by fishermen over many decades support this theory. 

Over the past decades a concentration of archaeological material, including worked bone, stone and human remains, has been found within the area around the Brown Bank, roughly 100 km due east from Great Yarmouth and 80 km west of the Dutch coast. 

The quantities of material strongly suggest the presence of a prehistoric settlement. 

As such the Brown Bank provides archaeologists with a unique opportunity to locate a prehistoric settlement in the deeper and more remote areas of the North Sea, known today as Doggerland.

Prospecting for such a settlement within the North Sea is a challenging activity.  Multiple utilities cross the area, bad weather is frequent, and visibility underwater is often limited.  Given these challenging conditions, researchers on the Belgian vessel, RV Belgica, used acoustic techniques and physical sampling of the seabed to unravel the topography and history of the areas chosen for the survey.  

During the survey, the team used a novel parametric echosounder from the Flanders Marine Institute (VLIZ). This uses sonar technology to obtain images of the sub-bottom with the highest possible resolution and was combined with the more traditional “sparker” seismic source to explore deeper sediments.  On the Brown Bank, the Belgica also deployed a grab and a Gilson dredge for sampling near-surface stratigraphy. Video footage was collated using VLIZ’s dedicated video frame and a simpler GoPro mounted on the Gilson dredge. A video showing the equipment in operation on the expedition can be seen at https://youtu.be/sGKfyrDCtmw

BRITISH COLUMBIA'S GREAT BEARS: NAN

Hiking in BC, both grizzly and black bear sightings are common. 

Nearly half the world's population, some 25,000 Grizzly Bears, roam the Canadian wilderness — of those, 14,000 or more call British Columbia home. 

These highly intelligent omnivores spend their days lumbering along our coastlines, mountains and forests. Or tucking away on logs to enjoy a favourite meal as is the case of the two youngsters here.

Both bear families descend from a common ancestor, Ursavus, a bear-dog the size of a raccoon who lived more than 20 million years ago. Seems an implausible lineage given the size of their very large descendants. 

An average Grizzly weighs in around 800 lbs (363 kg), but a recent find in Alaska tops the charts at 1600 lbs (726 kg). 

This mighty beast stood 12' 6' high at the shoulder, 14' to the top of his head and is one of the largest grizzlies ever recorded — a na̱ndzi.

Adult bears tend to live solo except during mating season. Those looking for love congregate from May to July in the hopes of finding a mate. Through adaptation to shifting seasons, the females' reproductive system delays the implantation of fertilized eggs — blastocysts —until November or December to ensure her healthy pups arrive during hibernation. If food resources were slim that year, the newly formed embryo will not catch or attach itself to her uterine wall and she'll try again next year. 

Females reach mating maturity at 4-5 years of age. They give birth to a single or up to four cubs (though usually just two) in January or February. The newborn cubs are cute little nuggets — tiny, hairless, and helpless — weighing in at 2-3 kilograms or 4-8 pounds. They feast on their mother’s nutrient-dense milk for the first two months of life. The cubs stay with their mamma for 18 months or more. Once fully grown, they can run 56 km an hour, are good at climbing trees and swimming and live 20-25 years in the wild. 

A Grizzly bear encounter inspires a humbling appreciation of just how remarkable these massive beasts are. Knowing their level of intelligence, keen memory and that they have a bite force of over 8,000,000 pascals — enough to crush a bowling ball — inspires awe and caution in equal measure. 

They have an indescribable presence. It is likely because of this that these majestic bears show up often in the superb carvings and work of First Nations artists. I have had close encounters with many bears growing up in the Pacific Northwest, meeting them up close and personal in the South Chilcotins and along our many shorelines. 

First Nation Lore and Language

In the Kwak'wala language of the Kwakiutl First Nations of the Pacific Northwest — or Kwakwaka'wakw, speakers of Kwak'wala — a Grizzly bear is known as na̱n. 

The ornamental carved Grizzly bear headdress was worn by the comic Dluwalakha Grizzly Bear Dancers, Once more from Heaven, in the Grizzly Bear Dance or Gaga̱lalał, is known as na̱ng̱a̱mł. 

The Dluwalakha dancers were given supernatural treasures or dloogwi which they passed down from generation to generation. 

In the Hamat'sa Grizzly bear dance, Nanes Bakbakwalanooksiwae, no mask was worn. Instead, the dancers painted their faces red and wore a costume of bearskin or t̓ła̱ntsa̱m and long wooden claws attached to their hands. You can imagine how impressive that sight is lit by the warm flickering flames of firelight during a Winter Dance ceremony.

Smoke of the World / Speaking of the Ancestors — Na̱wiła

Kwaguʼł Winter Dancers — Qagyuhl

Should you encounter a black bear and wish to greet them in Kwak'wala, you would call them t̕ła'yi. Kwakiutl First Nations, Smoke of the World, count Grizzly Bears as an ancestor — along with Seagull, Sun and Thunderbird. 

To tell stories of the ancestors is na̱wiła. Each of these ancestors took off their masks to become human and founded the many groups that are now bound together by language and culture as Kwakwaka’wakw. 

The four First Nations who collectively make up the Kwakiutl are the Kwakiutl (Kwágu7lh), K’umk’utis/Komkiutis, Kwixa/Kweeha (Komoyoi) and Walas Kwakiutl (Lakwilala) First Nations. There is likely blood of the Lawit’sis in there, too, as they inhabited the village site at Tsax̱is/T'sakis, Fort Rupert before the Kwakiutl made it a permanent home. It is where I grew up and I call all who speak Kwak'wala Cousin.

Not all Kwakwaka'wakw dance the Gaga̱lalał, but their ancestors likely attended feasts where the great bear was celebrated. To speak or tell stories of the ancestors is na̱wiła — and Grizzly bear as an ancestor is na̱n helus.

Image: Group of Winter Dancers--Qagyuhl; Curtis, Edward S., 1868-1952, https://lccn.loc.gov/2003652753. 

Note: The Qagyuhl in the title of this photograph refers to the First Nation group, not the dancers themselves. I think our dear Edward was trying to spell Kwaguʼł and came as close as he was able. In Kwak'wala, the language of the Kwaguʼł or Kwakwakaʼwakw, speakers of Kwak'wala, the Head Winter Dancer is called t̕seḵa̱me' — and to call someone a really good dancer, you would use ya̱'winux̱w. 

Charmingly, when Edward S. Curtis was visiting Tsaxis/T'sakis, he was challenged to a wrestling competition with a Giant Pacific Octopus, Enteroctopus dofleini. George Hunt (1854-1933) had issued the challenge and laughed himself senseless when Edward got himself completely wrapped up in tentacles and was unable to move. Edward was soon untangled and went on to take many more photos of the First Nations of the Pacific Northwest. Things did not go as well for the octopus or ta̱ḵ̕wa. It was later served for dinner or dzaḵwax̱stala, as it seemed calamari was destined for that night's menu.  

URSIDAE: URSAVUS

Hiking in BC, both grizzly and black bear sightings are common. These majestic beasts live up to 28 years and nearly half the world's population, some 25,000 grizzlies, roam the Canadian wilderness.

Both bear families descend from a common ancestor, Ursavus, a bear-dog the size of a raccoon who lived more than 20 million years ago. Seems an implausible lineage given the size of their very large descendants.

An average Grizzly weighs in around 800 lbs (363 kg), but a recent find in Alaska tops the charts at 1600 lbs (726 kg). 

This mighty beast stood 12' 6' high at the shoulder, 14' to the top of his head and is one of the largest grizzlies ever recorded. This past September, the King of the forest was seen once again in the Washington Cascades -- the first sighting in over 50 years.

Grizzly Bears in First Nation Lore and Language

In the Kwak'wala language of the Kwakiutl First Nations of the Pacific Northwest — or Kwakwaka'wakw, speakers of Kwak'wala — a grizzly bear is known as na̱n and the ornamental grizzly bear headdress worn by the comic Dluwalakha grizzly bear dancers in the Grizzly Bear Dance, Gaga̱lalał, is known as na̱ng̱a̱mł. 

There is another grizzly bear who features in the Hamatsa dance, known as Nanes Bakbakwalanooksiwae, a high-ranking figure who has no mask — instead, the dancers paint their faces dark red to symbolize a hungry bear mouth and dance in costumes made of bearskin with terrifying long wooden claws.

NORTH SEA DOLPHIN VERTEBRAE: HATSAWE'

A lovely 17 cm deep chocolate brown fossil Bottlenose Dolphin, Tursiops sp. vertebrae found in the Brown Bank area of the North Sea, one of the busiest seaways in the world.

Bottlenose dolphins first appeared during the Miocene and swam the shallow seas of this region. 

We still find them today in warm and temperate seas worldwide though unlike narwhal, beluga and bowhead whales, Bottlenose dolphins avoid the Arctic and Antarctic Circle regions. 

Their name derives from the Latin tursio (dolphin) and truncatus for their characteristic truncated teeth. In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest — and part of my heritage — dolphin are hatsawe'. 

On the north end of Vancouver Island, we have pods of 50-100 Pacific White-Sided dolphins, cousins of the Bottlenose, who frolic and jump alongside your boat if you are out on the water. Similar to their southern cousins, Pacific White-Sided dolphins feed on salmon, herring, pilchards, anchovies, needlefish, squid, shrimp, pollock, sablefish, rock cod and other small fish — a tasty menu that reflects my own. 

Bottlenose dolphins are the most common dolphin species in the Pacific Northwest but do not often venture farther north than Oregon. We have two populations of bottlenose dolphins here, the California coastal population and those that prefer to live offshore. It is as exciting to see them playing in our oceans today as it is to see the fossil remains of their ancestors from the Brown Bank sediments of the North Sea.
