I think it sad that we've assigned it a human name. We've no right to do that, it probably already has a name.

[@lenabreijer1311]

​@@JohnyG29 but until we know that name we can call it this name which is actually a translation to English of its native name.

@@SPierre-dm4wo I think we do know Orca well enough but she needs to be in a pod we can observe and listen to. As I understand it, we have identified that they do have names for each other. We don't hear them using their own name much but they do seem to react to othes calling them.

[@SPierre-dm4wo]

[@Mikailodon]

Because of these tusks, I personally now love to call O. rastrosus the "woolly salmmoth". Also, as an astrobiology guy, I hope we do find life on Mars soon, living or fossilised, and not just spider-y gas illusions. Perseverance better keep on looking…

[@rumpleforeskin1812]

What about calling it the "mammoth salmon?" It would be an appropriate name in two ways.

Nice to see that I'm not the only one impressed by the successful pronunciation of undeniably difficult names. Forgive me. I'm an auld goat who is simply pleased to see young people doing well.

[@benmcreynolds8581]

First we have a saber toothed deer. Now a saber toothed salmon. Starting to think that's a semi common convergent evolution trait. I loved that Orca story. I grew up alongside Kakio at the Oregon coast aquarium in the 90's-00's

[@Big-Chungus21]

It is a fairly simple and common trait to convergently evolve. “Saber tooth” is a term used to say “large canines” or similar tooth (I don’t think salmons have canines haha). Evolving larger teeth is similar to evolving larger and smaller muscles or limbs, ears, noses etc so in my opinion isn’t anything as especially unique as convergently evolved body plans or camera-type eyes. I guess the interesting part of convergent evolution between the salmon and deer would be the exact reason - to fight off predators and compete with mates, for which this does at first seem to be unique to the salmon and deer. However, there are other animals like mandrills and baboons (super unique case of convergent evolution in its own right), even chimpanzees that also have this trait, alongside it also being useful for those purposes in most predatory mammals like dogs and cats. You could also include animals like boar for animals that evolve sharp teeth for defence.

[@simonwilliams4514]

[@Joe_Brennan_]

Fell to the floor in ASDA when I heard this news

[@kensmith5694]

A 2meter long Salmon would be a very big fish for swimming up stream. I never bought the idea that T. Rex was smart. I don't think there was any explanation of a evolutionary pressure pushing them in that direction. A big brain costs a lot to run. Stronger chompers would bring more ability to eat. Those two features would be competing in the weight and balance stuff of T Rex. If the head gets heavier, something has to get lighter in front of the hips or the tail has to get bigger.

[@theabstractguy411]

Personally, I’m gonna go with boar-headed salmon. Cooler name. Anyways, the paleo news this week was pretty good. Can’t wait for next week’s!

[@kluk8284]

I’d call it the “tusked salmon”

[@TheRenegadeHamster]

hehe I love this show. I never thought I'd be psyched about a fossil shark! I'm gobsmacked they got such a good fossil for ptychodus! I was really ready to be heartbroken over the orca, so I'm glad they're free. Lots of interesting stuff!!!

[@platedlizard]

Great video! Always fun to see one of my finds being featured, in 2011 my dad and I visited the Gateway quarry where these salmon were found and located several salmon. We contacted the University of Oregon and excavated them, finding intact skulls. Later excavations at the site revealed more skulls. The Gateway Quarry in Oregon is the only known breeding site for the giant salmon and it's likely these fish died after breeding as modern pacific salmon do. We continue to do excavations at this quarry and there are some exciting new discoveries there I'm not at liberty to talk about 😉

If anything I'd imagine a T-rex to have an intelligence level of crows or parrots, maybe slightly higher, but nothing close to a primate.

[@tjarkschweizer]

Crows and parrots are actually smarter than most primates. They can easily compete with chimps. There's no way a Tyrannosaurus was any smarter than a crocodile. Not that crocodiles are stupid but seriously, their brains look almost identical.

[@jeroenschoondergang5923]

Thanks for the updates. The spikes on the sides of the jaws of the Oncorhynchus rastrosus make sense, if you watch pacific salmon species during their spawning run. With most species the males are very aggressive in standing their ground/gravel bed. Is there a theory about the teeth being part of the spawning dress of the males or if they were apparent year round?

[@FrancisFjordCupola]

Very much enjoyed this episode. That Salmon, though, looks more like a nose ring. Noseringius Salmonis.

[@tinamclaughlin1991]

[@velutumbra]

Spiders on Mars: Mars is the Australia of the Solar System. Emilia, had you not pointed out the nails detail, no one would have noticed that in the middle of your brilliant presentation (although we can start a petition for Ben to hire an on site manicure).

[@rileyernst9086]

The way i see it, is you have to kinda ask if it makes biological/ecological sense that a Trex has baboon like inteligence. Does it seem to be doing anything that requires a baboon like inteligence? - probably not. Also if you're using phylogenetic bracketing and brain shapes most therapods match closer to modern crocs than modern birds. And modern crocodilians keep proving themselves a surprisingly high 'low bracket' for inteligence demonstrating novel behaviours and nuianced social heirachies.

Constituting the tribe Oncorhynchini, pacific salmon and trout, in addition to taimens and lenoks are all found in Asia and Western North America, it differs geographically from the tribe Salmonini that contains the atlantic salmon and trout in addition to both the chars and huchen and is found in both Europe and Eastern North America, the genera Salmo and Oncorhynchus only share superficial similarities due to convergent evolution as both genera typify two different tribes.

So disappointed they were not really spiders! Relieved about Brave Little Hunter! Have joined on this account, as it is more convenient than my previous subscription. You're a godsend, I can be really lazy and allow you to keep me up to date with what's going on. I appreciate that animal behaviour can be extrapolated from brain size and intelligence, however I think one can get too hung up on it, and as a lay person I am not entirely sure about what intelligence in other animals (living and extinct) is based upon. I hope it isn't on our own intelligence, a survival characteristic which appears to be coming to the end of its usefulness with our apparent inability to carry on adapting as a species. I hope you can assure me that it is a combination of ignorance and pessimism on my part and that our outlook is brighter than I think! Not your area of expertise I know, just a personal worry.
