Woah - I had never heard of the Hatzegopteryx. I spent some time today watching videos of this guy today (and its relatives, Quetzalcoatlus and Argentinosaurus). They are really cool.
I know that there is a lot of arguments about what dinosaurs actually looked like - I hope that in the videos they make these guys scarier than they actually were... This video is especially: https://www.youtube.com/watch?v=pYniD_MQ7Rg
Personally, this style (from a great PBS Eons video) is my favorite interpretation:
I am going to be that guy and point out that pterosaurs were not dinosaurs, unless you consider primates to be squirrels cause we are distantly related. Also fun fact pterosaurs may have had a type of feathering which either means that the ancestors of both dinosaurs and pterosaurs had feathers or it evolved at least twice. And on a similar thing of body coverings, stem mamals/proto-mammals had fur before the dinosaurs ever evolved.

Ah, thank you for being that guy! Now I know 😄

Can the feathers and fur (or their impression) be preserved for millions of years in some types of fossilization? Or is the presence of these concluded from the bone structures, fossilized skin, or other not so direct pieces of evidence? And, is any direct evidence of color preserved? No pressure to answer, I am just wondering out loud.
On the preservation thing, it depends but it usually comes down tp either skin impressions, soft tissue fossilization, or imprints kinda like fossil footprints. You were basically on point with your guess. But yeah this type of evidence is varried and highly temperamental in how we find it.
I think the only thing that preserves worse are soft bodied organisms like jellyfish. But yeah if ya want to learn more on this shit PBS Eons on youtube is a pretty solid start.
But weight is gravitational force not mass. These are deeply related but not the same because us customary is based on pre Newtonian measurement systems
If you say that something "weighs" something, that's a description of mass, not weight, because the wording is from before a time when it was understood that mass and weight are different things.
All has been said that needs to be said, bloody pedant.
I was mostly just joking. Of course we use lbs as pseudomass. Fuck, we’ve moved to lbm vs lbf in America because mechanical engineers must be stopped and metricated by force if necessary. We’re a spacefaring species that’s advanced enough to have planetary gravitational maps, of course mass is what we should be using. But also weight as force is just kinda funny to use outside the myriad times you actually need to in engineering
We are not talking about the weight force here. We are simply converting pounds-mass to kg. If you dont believe OP meant the mass (whicg Im sure he certainly did) then aks him but when saying something weighs a certain amount then one is usually referring to its mass.
In both the British Imperial System and the US Customary Units, a pound is a unit of mass, defined as 0.45359237 kg. In fact, all the definitions in the section "Weights and Masses" of the US Cusomaries are defined in either kg, g or mg.
A pound is actually not a unit of force. At least not in the US Customary System nor in the British Imperial System. They both are defined as units of mass. Both systems define the standard pound as the "avoirdupois pound", a unit of mass. The US Customary System doesnt even include a unit of force.
"Pound-mass" comes from the "English Engineering Units" which differentiates between pounds-mass and pounds-force.
"Pound" is not a unit of force in any current system. Its the standard unit of mass (slug is also a unit of mass but usually not used). Feel free to provide any source that states that pound is a unit of force.
We were actually talking about Force, though. Pounds is a force, not a mass. I am OP and I meant force because I'm assuming the animal lived on earth. If I wanted to specify mass then I would have used Slugs, the Imperial unit for Mass.
Did you take into account that earth was heavier millions of years ago? Also, you would have to specify where on earth it weighed that amount.
Anyway, pound is an imperial unit for mass, just like slug.
The "pound-force" is not part of the imperial units, jut rather of the "English Engineering Units" that differentiate between pound-mass, pound-force, pound-foot and others.
"Pound" is not a unit of force in ANY system. If you really meant force (I doubt that) you should have used lbf. Anyway, noone cares how many Newtons of force the earth exhibited on that animal, all the metric-using people in this thread are interested in its mass. All scales used to weigh something display kg (or pounds), so units of mass.
The dino would need to be even lighter if the earth was heavier because the force of gravity would be higher, but in general differences in gravity across the earth's surface amounts to a rounding error. For example, you're probably looking at 2000 ish miligal from the top of a tall mountain to sea level difference in gravity, or .02m/s^2 difference.
Could you provide any source that states that a pound is a unit of force? Because the American National Standard Institute (here), aswell as Wikipedia and numerous other sources claim its a unit of mass.
The article you linked to does not mention at any point that LBS is a mass, or at all uses the word mass at any point throughout. In fact, it breifly at the end mentions "1 lb=0.45359237 kilogram" as well as "1 Newton=0.224809 pound force" which could indicate a difference between LBF and LBM distinctions.
It's commonly understood that you will weigh a different amount of lbs on the moon than on earth. Because it isn't a mass. It's a force of gravity.
There is also evidence in the form of lbs/in^2 being a common measurement, which would be completely nonsense in the context of mass.
Alright, lets look at the US Customary Units and their definitions. Here is the section called "Mass and Weight". As you can see, everything is defined in metric units of mass. You won't find even pound-force to be part of the Customary units. I couldn't find any source saying that pound (not "pound-force") is a unit of force. However, there was an agreement (I think in 1955) to define the pound in kg.
it breifly at the end mentions "1 lb=0.45359237 kilogram" as well as "1 Newton=0.224809 pound force"
That basically implies that lb (pound, imperial unit) is a unit of mass and "pound-force" (non-imperial unit, part of the British Engineering Units) is a unit of force. Thus, pound (on its own) is a unit of mass, right?
Agree. The error is in the imperial system, there isn't a difference between weight and mass. The Weight depends on the gravity but the mass not. 240 Pounds Weight on Earth are on the Moon 40 Pounds Weight, but the Mass is still 240 Pound. Because of this in the SI system for the Mass is used kilogramm and for the Weight Newton (old kilopond)
LBS is Imperial Pounds which is a measure of Force and not Mass. That is why your LBS fluctuates based on gravity but your mass doesn't. So they are correct.
Yes, this birdy certainly looks like a person in disguise, almost also because of the size. Watching this at night in a forest will put your balls in your throat.
Oh man, this movie had such an impact on a couple of generations of Scandinavians. I've talked to multiple folks in the BDSM community who had their sexual awakening to the scene where Ronja is tied underground by the small elf people.
As a small mammal compared to that my evolutionarily developed survival instincts must be off. I want to befriend it. I assume it wants to eat children though.
I'm sure they're great. I'm not gonna lie though, I'd be slightly frightened if one was on me. But I'm from NNA, so there's nothing quite that big here.
Ya see, this i don't mind getting eaten by. But OP's pic looks like some sort of eldritch horror that would have me spiral into madness before devouring me.
Thank you for the perfect complementary comment, sincerely,.
Haha, I actually laughed out loud.
You're entirely right.
I love the different interpretations of concept artists, whether they're galactic or paleontological or whatever, it's always fun to see the differences between what people come up with.
It's odd that razor sharp teeth is kind of the gold standard for a scary animal, but honestly, getting swallowed whole and slowly digested by stomach acid sounds so much more horrific. I'd so much rather a T-Rex eat me than that.
Probably not enough volume to engulf you and make you drown. Usually stomach acid is strong enough to irritate but not dissolve a whole prey, so those two are out. However accidental inhalation and fumes might be a motherfucker and getting it into the eyes would be horrendous.
Two possible scenarios:
Suffocation due to a lack of oxygen.
Crushed to death by the stomach. It is conceivable that this baby (slaps roof of the dinosaur) can crush large prey to death in the stomach and grind it to small bits by having an especially strong muscle lining.
The stomach isn't like a big cave with a pool af acid in it. It is compacted by muscles around it so if you are swallowed whole, you would have to fight against those muscles to even be able to move at all. If your arms are above your head it's likely you would die before you are able to move them to your hips to draw your knives. If they are at your hips, good look moving the knives to point outwards. Also the stomache is lined with thick mucous to protect it from sharp objects...
Also it's completely dark and disorienting.
It's almost certainly you'd drown, suffocate and get crushed VERY quickly after getting swallowed alive.
The stomach isn't like a big cave with a pool af acid in it.
Unless your predator has been eating a lot of air or drinking a lot of soda/beer. Although one burp would quickly get rid of all that headroom. And the CO2 from carbonation would quickly suffocate you as well as it's heavier than air.
You can blame the Magic School Bus for my incorrect perception of how the stomach works. I know they cleared things up at the end, but as a kid I remembered only the adventures.
I recall reading a meme about the ocean being bullshit, something along the lines of "the most common way to die on land is something making your blood fall out".
