A cloned Dino would immediately die as the Earth's oxygen level was far higher in the past: It would suffocate.

Bottom line: no really big dinosaurs will ever exist in our modern earth even if they do clone them. If they ever do clone them best we can hope for would be something in the 7 ton range.(elephant size)
The environmentalists won’t have it. Just think of the dino farts and poop giving off all the methane. /s
Brains overcame brawn.
This has been my take for 15 years.
Interesting. If cloned, based on the article, they'd need help to get around - each would need a taxpayer-provided walker, crutches... perhaps we'd need huge wheelchairs to move them around. The handicapped laws would be amended to accommodate them, with large ramps, and very large parking spots in front of all buildings and offices.
Hasn’t the author, Ted Holden been banned from FR multiple times?
As a child in school (1950s) we were taught brontosaurs lived in water because they could not walk on land due to their weight, and Tyranosaurs walked upright dragging their tails on the ground. It was settled science!
Wonder what “new” things they will decide about in the next fifty years.
Gravity is a problem for Michael Moore and Rosie O’Donnell too. But why aren’t they extinct???
It is instructive that the ancients worshiped Jupiter and Saturn as the two chieftain gods in all of the antique religious systems. If the present solar system was present in the distant past, one would expect primitive peoples to have worshiped the most visible of the astral bodies: the Sun, the Moon, and Venus. There is no conceivable reason they would worship as gods two planets which most people cannot even find in the night sky — unless, of course, these bodies occupied a far more prominent place in the heavens than they do today.
Or perhaps the alleged collision that caused the moon and added mass to the earth had not happened yet?
Thought that was the argument for the now-”debunked” young earth theory, though that would not agree with “settled science”.
(Now that we recently re-wrote all the History, Science and Astronomy books to include the Fraud and his anthropomorphic climate change dogma).
I’ve thought about this in the past though the author obviously knows a lot more about dinosaurs than I do. I think the most likely explanation is that the gravity of the Earth was less in those days. Maybe the Earth simply had less mass but I suspect it’s more that the laws of physics themselves DO change despite the claim in the article. The physicists aren’t close to accepting that though.
For anybody who wants to cleanse their brain:
OK... Interesting concept, but the ratio is wrong when they scale him up to 70,000 lbs. “x” in the numerator cannot be smaller than 70,000, since the comparison ratio is 1340 over 340. “x” = 275,882, not 47,558
Stopped reading there. Open to correction. ‘Splain it to me.
If it was a gravitational-constant change, the planets would have careened out of orbit or into the sun.
The primary reason stated is that the Earth had much more oxygen in the atmosphere then, allowing for larger sizes of animals, insects, and so on.

Oxygen levels were much higher 60 million years ago.
The average modern human would have been a fully doped Lance Armstrong if teleported back in time.
Cloned dinosaurs would gasp for air in our atmosphere.
People need to be careful with their arguments. Let the evolutionist be the sloppy ones often teaching badly outdated notions of evolution in public schools if only because its hard to keep up ... and also keeping up may not be important if, as is likely the deep motivation, evolution is used as a way to foster secularism and atheism through the schools.
Most dinosaurs weren’t huge.
But for the biggest there may be a way to explain why they grew so large: possibly poor quality food.
The normal views on ancient plant life from looking at the teeth was that it was frequently tough fare.
Now, there are tough to digest plants being eaten by herbivores all the time today, such as grass, and the way active creatures (not talking koalas who sleep off their meals a lot) to digest. Among the most efficient if fermentation which is likely method used by the biggest dinosaur herbivores.
Cattle for example use fermentation with their multisegmented stomach (4 chambers IIRC) that serves to efficiently digest but they have a number of additional tactics, like chewing their cud, that dinosaurs probably didn’t have.
But if relying strictly on fermentation there would be a real benefit from having a very big stomach or just lots and lots of intestines because fermentation is one of those processes that benefits from economies of scale, with a big stomach taking less energy for a given amount of food to extract the same energy.
So a big stomach translates into a big animal. The classical long necked giant would have also had to have moved less since they could swing their heads side to side sucking up whatever they came across.
With generally better quality plant food and sometimes better strategies to digest what is marginal, there simply is no advantage to growing so very big, never mind huge, and with big herbivores being smaller / less common there’s reduced opportunity for there to be big meat eaters.
ρF = ρS (1 - 1/S.F.)
where ρF is the density of the fluid, ρs is the density of the substance submerged in the fluid such as the dinosaur, and S.F is the scaling factor. Inserting into this equation a scaling factor of 3.2 and an overall vertebrate density of 970 kg/m3, the Earth's atmospheric density during the late Jurassic period can be calculated to be 670 kg/m3. This says that to produce the necessary buoyancy so that the dinosaurs could grow to their exceptional size, the density of the Earth’s air near the Earth’s surface would need to be 2/3’s of the density of water. (ref: https://dinosaurtheory.com/solution.html)
I wish democrats would go the way of the dinosaurs.
An interesting premise but...why are modern horses so much bigger than their forebears like Eohippus...which was two feet tall?
I think we covered this before.
There’s not as much oxygen in the atmosphere as there used to be.
