Despite being upset for not being able to attend to it in person, it's a delight to watch it nevertheless and I'm really thankful to the Ri for posting this lecture. I have thought of becoming a paleontologist and dig, specially to look for spinos, but I definitely have no means to pursue this goal. However, it's nice to have Hone calling potential paleontologists out and it makes me consider following such path after I get a stable life. Amazing lecture as always, Mr Hone. Thank you.

The bourbon reference in the video on the tyrannosaurs was so good😂

Dave really is the best. Love listening to him talk about Dinos. I've sent links to his T-Rex talk to several people when he did that one.

That large sail and tail would be great to create shade to attract fish and even channel them in slews and creeks to force the fish to swim past the head.

Couldn't the explanation for Spinosaur eating terrestrial prey be that it's an ambush predator like a crocodile? I'm guessing there are lots of crocs that share a similar diet to non aquatic animals

A marvellous talk.

What an excellent lecture. It has helped consolidate what I know about spinosaurids and also helped me interpret the modern arguments about the lifestyle; hell heron is a fantastic metaphor and to be honest it sums up everything, herons are fucking brutal, they eat fish sure but they also eat baby crocs, ducklings and even ducks and storks are even more capable of non-piscarine prey.

I love that Spinosaurus has become the aquatic monster that the early 1800s scientists thought all dinos were.

Great stuff.

Absolutely Based and Well presented upload ! Dr Holtz Dropping the facts!

I am no specialist, but I have my little out-of-the box layman's hypothesis with regard to the more aquatic-like version of the spinosaurus species. Although the sail would make it top heavy and a poor swimmer in a pond or a river, this condition would change in more open, windier waters. From my experience as a windsurfer, if you are standing with an open sail in still waters, it is very difficult to maintain your balance, but as soon as a small breeze starts to blow, the pressure of the wind on the sail and the resulting inceease in side resistance on the keel propells you forward. Four legs acting as keels and the additional tail fluke sticking out of the water would give the lizard additional sail surface and a better direction control than a windsurfer would be able to achieve. The sail and tail surface may not compare to the surface of a windsurfer's sail, but it would definitely enable this creature to effortlessly cruise long distances, and the tail could be used for a quick propelling action when encountering prey. As for the nose not being in the front, this would be more useul in windier choppy waters, as the nose in this case would be higher than the crest of the waves. Now, with reference to the example of modern aquatic lizards pointing out the differences between male and female as an argument for the sale being merely a courtship display feature, I would venture to say from my layman's, perhaps uninformed point of view that females don't have a sale like males do maybe because the males are more specialized as hunter-providers than females.

I was thinking that if not a full blown swimmer, if it may have submerged most of its body, using the sail as temperature regulation.

This fellow knows how to draw you into his passion and clearly explain it - I love his lectures!

I wonder if spinosaurous used their sail as a shade to create areas that fish would congregate in. the spinosaurus could than eat the fish from the shaded area. There may be evidence of this if there are snout marks in ancient river trackways adjacent to spinosaurus foot prints facing roughly perpendicular to the direction of the bite marks. There may be a lack of evidence if they were delicate eaters and would not get their snout all the way on the bottom such that it could make an impression. Modern bird behavior of shading areas of the water to allow fish to congregate in is seen in certain herons I think. It seems many species of spinosaurus would be able to specialize in various types of fish that need to be attacked in different ways.

@Charlie-Charlot

2 жыл бұрын

I thought about that too, that could be a good explanation. Also, Spinosaurus would be quite vulnerable when fish hunting, having its snout in the water and being relatively lightly built in an ecosystem full of other large predators may be a bit dangerous, a large sail in the back and on the tail might help appear larger and scare them away

Ceratosuchops and Riparovenators and Baryonyx Oh My!

Such a good lecture! I'd like to know why we don't have any more complete skeletons considering they appear to have lived near rivers that are usually good for preservation.

Biology and animal sciences along with geology

The spinosaurs should be still be here today

Is it's neck long enough and is there signs of muscle connection points to support the motion required to hunt in that way?

Try watching the BBC movie Planet Dinosaur because it shows the Spinosaurus and the Carcharodontosaurus. I also have Planet Dinosaur on DVD.

28:38 - I've always thought about the back sail as having some display function, but also being quite a pragmatic solution to regulating one's body temperature. Probably an especially useful adaptation for an animal that wades a lot in water, or better still, ambush hunts by standing in said water for prolonged periods of time. Tropical climate or not, colder weather or colder water happens and water will sap your body heat away eventually. Exposing your sail, or even a tail to the sun to help to offset it means saved calories

Funnily enough two months after David Hone held this talk a new study was published called "Subaqueous foraging among carnivorous dinosaurs" that talked about how Spinosaurus was not just a specialized aquatic hunter, but a proficient underwater hunter as well. Quoting the paper: "Spinosaurids are revealed to be aquatic specialists with surprising ecological disparity, including subaqueous foraging behaviour in Spinosaurus and Baryonyx, and non-diving habits in Suchomimus" So yeah, worth noting that this is a much more controversial topic than this lecture gives the impression of. Just in general, and this might just be me, but I'm not a huge fan of telling the general public, who of course don't really know all the ins-and-outs, these things like they're absolute facts when they're still controversial. Like "But certainly not a a high-speed pursuit predator or a particularly good deep-diver", that makes it sound like it's settled when it really isn't. I think changing "certainly" to "In my view" is better form.

@qbgrindddd

25 күн бұрын

I mean, it kind of is settled that Spinosaurus was not an incredible swimmer though better than other theropods - it was certainly semiaquatic and swam occasionally but defintely was not an aquatic pursuit predator. There was a recent paper by Paul Sereno claiming "Spinosaurus is not an aquatic predator" (that is the title of the paper).

To me, as soon as i saw the first major update on Spinosaurus, with the short legs and spined tail, i immediately thought of shallow water ambush hunter - like a heron. Everything about its physiology screams heron-like hunter. I picture spino being just like the picture by Bob Nicholls at 32:30. It having such a long, straight tail actually makes sense as a counterweight for an animal that is primarily ankle and muzzle-deep in water most of the time. I do think though that spino was possibly in a somewhat transition point before going extinct. I mean that it was possibly still a decent swimmer and slowly transitioning into more aquatic life. You can see this with its legs getting shorter, mainly. I wouldn't be surprised if it is later discovered to have had webbed feet. The spino, as opposed to the Baryonyx, was not a very quick animal at all. It's so massive with very small legs, so there was no real way it could be very fast. This supports it being a waterside ambush predator even more. Baryonyx and Suchomimus, however, seemed like a type of animal that was likely an earlier, less specialized version of what spino ended up becoming. Maybe they started as a more typical theropod, but some branches became incredibly specialized, becoming Spinosaurus.

@qbgrindddd

This is very correct. Spinosaurus was definitely a shallow water ambush predator - though its body is streamlined enough to swim

Fish is delicious. I would specialize in fish and some crunchy shellfish for desert. Yum Yum.

I wish I had seen this when it was new. It's clear from the puny legs that Spinosaurus would not have been any more able to chase things on land than in water. And it clearly didn't care if it was seen by potential prey...or could being seen actually be an advantage? For a klepto-carnivore, yes! Being perceived as bigger than you are would be a distinct plus. And being heavily armed on the front end would mean it could deal easily with any resistance. Dig up a few lungfish, and it's a living.

Great lecture and presentation, except one single issue: When Hone shows some details under that lamp, we only get to see it in a semi blurry view on the screen, from across the whole theatre, in a wide shot.
