How prehistoric dogs hunted, new study


This December 2017 video says about itself:

There are many extant wild canids of North America including the gray wolf, the coyote, the hybrid red wolf, the Arctic fox, the gray fox, the red fox, the swift fox and the kit fox.

But North America was once home to many other canid or canid like species which are only known from fossils they have left behind. With exception of ‘’Dire wolf’’ which is a much better known extinct Canid, many other little known species of Canid or Canid-like species are known from scant fossil records and were endemic to North America.

Following are 5 lesser known Canids of Ancient North America you have probably never heard of:

1 — Epicyon (15-5 Million years ago)
2 — Borophagus (12 –2 Million years ago).
3 — Carpocyon (13.6 –5.3 Million years ago).
4 — Aelurodon (16 –5.33 Million years ago).
5 — Canis lepophagus (10.3 –1.8 Million years ago).

Skull scans tell tale of how world’s first dogs caught their prey

January 11, 2019

Analysis of the skulls of lions, wolves and hyenas has helped scientists uncover how prehistoric dogs hunted 40 million years ago.

A study has revealed that the first species of dog — called Hesperocyon gregarius — pounced on its prey in the same way that many species, including foxes and coyotes, do today.

The findings also show that the largest dog species ever to live — known as Epicyon haydeni — hunted in a similar way. The animals — which lived from 16 until seven million years ago — could grow to the size of a grizzly bear.

Comparisons between computerised scans of fossils and modern animals have shed light on the hunting methods used by prehistoric members of a group of mammals known as carnivorans. These include modern-day foxes, wolves, cougars and leopards.

Scientists at the Universities of Edinburgh and Vienna used the scans to create digital models of the inner ears of 36 types of carnivoran, including six extinct species.

The team found that the size of three bony canals in the inner ear — the organ that controls balance and hearing — changed over millions of years as animals adopted different hunting styles.

Faster predators — such as cheetahs, lions and wolves — developed large ear canals that enable them to keep their head and vision stable while ambushing or chasing prey at speed, the team says.

Their findings reveal that inner ear structure indicates whether a species descended from dog-like animals or belongs to one of four families of animals resembling cats. A distinctive angle between two parts of the inner ear is much larger in dog-like animals, the team found.

The study is based on research carried out by Julia Schwab, a current PhD student at the University of Edinburgh, during her MSc studies at the University of Vienna, Austria. It is published in the journal Scientific Reports.

Ms Schwab, based in the University of Edinburgh’s School of GeoSciences, said: “For me, the inner ear is the most interesting organ in the body, as it offers amazing insights into ancient animals and how they lived. The first dog and the largest-ever dog are such fascinating specimens to study, as nothing like them exists in the world today.”

San Francisco, USA extreme right rally flops

‘Minefield’ For Nazis Planned By Dog Owners

25 August 2017

Dog owners in San Francisco want to prepare a smelly surprise for a right wing rally in their city. Brett Erlich, Grace Baldridge, and Amberia Allen, the hosts of The Young Turks, tell you how they’re planning on fighting back.

“When a group of far-right activists come to San Francisco to hold a rally this Saturday, they will be met by peace activists offering them flowers to wear in their hair.

Also, dog shit. Lots and lots of dog shit.

Hundreds of San Franciscans plan to prepare Crissy Field, the picturesque beach in the shadow of the Golden Gate Bridge where rightwing protest group Patriot Prayer will gather, with a generous carpeting of excrement.

“I just had this image of alt-right people stomping around in the poop,” Tuffy Tuffington said of the epiphany he had while walking Bob and Chuck, his two Patterdale terriers, and trying to think of the best way to respond to rightwing extremists in the wake of Charlottesville. “It seemed like a little bit of civil disobedience where we didn’t have to engage with them face to face.”

Tuffington, a 45-year-old artist and designer, created a Facebook event page based on the concept, and the dog owners of San Francisco responded in droves. Many have declared their intention to stockpile their shitpiles for days in advance, then deliver them in bags for the site. (The group is also planning to reconvene on Sunday to “clean up the mess and hug each other”.)”

San Francisco Dances That Far-Right Rally Out Of Town

It was a day for MC Hammer, not white supremacists.

A controversial “Freedom Rally” planned near the Golden Gate Bridge in San Francisco was canceled and replaced by a procession of dancing and merriment on Saturday.

The city had prepared for a street battle between the so-called “alt-right” and counterprotesters, but instead it got MC Hammer leading the public in song outside City Hall.

Much like the “Free Speech” rally held in Boston last weekend, where the cries of a few attendees were muffled by tens of thousands of protesters, this far-right rally had a much smaller voice than the city it occupied.

Hundreds of people were seen marching through the streets of San Francisco, decrying the white supremacists and other extremists that too many of these rallies have attracted this year.

The organizers of the aborted Freedom Rally ― who ended up giving a press conference via Facebook from inside a home with the blinds drawn ― sought to distance themselves from the event in Charlottesville, Virginia, two weeks prior that attracted neo-Nazis, members of the Ku Klux Klan and a bevy of white supremacists. …

But there’s a reason why the city and its mayor, Ed Lee, attempted to block permits for the rally; why House Minority Leader Nancy Pelosi (D-Calif.) called it a “white supremacist rally at Crissy Field”; and why counterprotests were planned in opposition throughout the city: These rallies just keep attracting white supremacists, weapons and violence.

The Freedom Rally’s main organizer, Joey Gibson, is no stranger to how this works. The far-right icon has acknowledged that his rallies ― including one held in Portland, Oregon, in June ― attract white nationalists and other far-right extremists, many of whom bring along makeshift weaponry and spew forth hate speech. …

And though Gibson claimed this rally was set up to “spread a message of love,” you needed only to look at the planned keynote speakers to see an entirely different picture. One of them, Kyle “Based Stickman” Chapman, is an unquestionably violent far-right “celebrity” who has spent nearly a decade behind bars on three felony convictions. He earned his “Stickman” moniker after beating a protester with a stick at a violent pro-Trump rally in Berkeley. …

In the afternoon, crowds gathered at Ocean Beach in the shape of a heart and sang even more: crowd dressed in red and pink singing This Land Is Your Land and Imagine at Ocean Beach.
