The sabertooth salmon, now extinct, inhabited the waters off the Pacific Coast of North America 5-12 million years ago. Oncorhynchus rastrosus received its nickname from a pair of canine-like fangs that protruded outward from its snout.
Size comparison of the sabertooth salmon to man and today’s sockeye
The sabertooth salmon was huge, the largest of any salmonid to ever exist. Adults reached a length of 7.5 feet, and a weight of up to 400 pounds. Try dip netting for that beast.
Like today’s salmon, the sabertooth was thought to be anadromous, meaning they went from salt water to fresh water to spawn. O. Rastrosus would have shared the ocean with some rather large predators: Namely the Megaledon shark and the Livyatan, a predatory whale.
The United States will open the land borders with Canada and Mexico to fully vaccinated travelers in November. This will come as welcomed news to many border communities after 19 months of having the borders closed to visitors.
The American Lion went extinct approximately 11,000 years ago. A sister lineage to the European Cave Lion, the American Lion was 25% larger than today’s African Lion. In fact, they may well have been the largest feline to prowl the Earth’s surface, standing 3.9 feet at the shoulder. The saber-toothed cat was more stout and muscular, and the American Lion more lean. The two predators hunted in a very different style, with evidence showing the lion being built for speed.
Home range of the American Lion
The American Lion ranged from Alaska through much of what is now the western and central United States, Mexico and into South America.
Artist depiction of the American Lion
I’ve written on here before about the steppe bison at the Museum of the North that is on exhibit. The bison was quickly frozen after its death, and preserved in the permafrost. On its flanks, one can see the claw and bite marks from an American Lion.
There is some debate as to whether the species was actually a lion, or from the tiger or jaguar lineage, but most classify the species as being a sister line to the European Cave Lion, which was isolated after many thousands of years.
A complete skeleton of an American Lion
The above skeleton of an American Lion came from the La Brea Tar Pits, but there were relatively few found in the pits compared to the saber-toothed tiger. One theory is that the American Lion had one of the largest brain cavities of any feline, so it’s possible most of them were smart enough to avoid the tar.
No matter how you look at it, the American Lion was one, big cat. It must have been an impressive sight.
1920’s travel along the narrow gauge rail of what was originally the Tanana Valley Railroad. By 1920, the TVRR had been bought out and this section renamed the Chatanika Branch. In 1923 it all became part of the Alaska Railroad.
A little bit of controversy this year for Fat Bear Week. Otis beat out Walker for the fattest bear of Brooks Falls. This may have been a bit of a popularity contest in 2021, with Team Otis coming out in droves to vote for the fan favorite. With that said, it is hard to dismiss the amount of weight that Otis put on in just a few short months. It was a lot of poundage, especially considering that Otis showed up at the river later than usual this summer, and that he is now missing two canine teeth, and many of his teeth are worn down.
Congrats to the now 4-Time Champ, and best wishes in the off season.
Otis is no newcomer to Fat Bear Week. A three time winner of the championship, Otis was the inaugural winner back in 2014. He also took the title in 2016 & 2017. First identified at Brooks Falls in 2001, he is one of the older bears in Katmai. A patient fisher, Otis rarely chases salmon, and has one of the higher catch rates at Brooks Falls. One of Katmai’s all-time fan favorites, the aging bruin once again appears in the finals.
Walker, or Bear 151
Walker first showed up at Brooks Falls in 2009 as a two year old. Once known as a tolerant, playful bear, Walker has become a lot less tolerant as he has aged. As he has grown into a larger, dominate male, Walker has realized he can throw his weight around to gain prime fishing spots. Estimated to have weighed in at 1000 pounds last autumn, Walker looks to be even bigger in 2021.
Voting for the title round takes place today. Polls close at 5pm ADT.
