Trained humans can maintain a speed of ~20kph for hours (as in plural). Peak speed for a few seconds (which is what would be required to escape these animals if reaction time is not the problem) is ~50 kph for humans (but only for 10 meters or so). Apples to apples, humans are far superior to these speeds. The best animals for these measurements do crush these figures (by a factor of ~3), but I would expect that the…

> Trained humans can maintain a speed of ~20kph for hours The very best humans can only manage ~20kph for 2.05 hours (WR: 42.2km in 2:02:57 giving 20.59kph). Beyond that, the 50km WR is down to 18.3kph; 100km WR is 16.1kph; etc.

That's for modern humans. Bone density studies of humans ~10,000 years ago suggest our muscles were much stronger.

Endurance runners are not generally strong. Upper body strength for example is counter productive.

Further, Olympic paces are maintained by people getting aided with sports drinks at regular intervals etc. It's very different from the conditions primitive people would have lived.

Consequences be damned, if I could make Jurassic Park, I would.

If we are able to get any DNA out amber that would be amazing. From what I understand DNA is not stable for that long. If we are able to get any DNA it would probably be inferred some microscopic structures or something left behind from the DNA. However, even then I doubt it would be complete. So why it would be amazing it would just be tiny fragments of DNA. I doubt we will even get a tiny fragment. So highly doubt…

I wonder if we'll eventually find that all, or most, dinosaurs were feathered. I mean, it is a bit of a coincidence, that we find a dinosaur tail in amber and it just so happens to be from a feather dinosaur- it's a bit of a coincidence. Have other dinosaur body parts been found so well preserved?

the nodosaur found in Alberta doesnt seem to have had feathers. https://www.sciencealert.com/a-new-dinosaur-fossil-has-been-...

Neither does a tortoise. It doesn't seem like growing armor is conducive to producing feathers on top of it.

The drastic difference between 12mph and 25mph is where our problems would show up. Many predators can do 20+ mph for long enough to eat us. Polar Bear's top out at around 25MPH but they can sustain that long enough that the safe distance is around 1/2 mile. Brown Bear's are worse making running a bad idea. Endurance hunting is far more effective in very high temperatures so it's use as likely limited.

Humans are group animals. Try and stalk an individual wolf in a pack as an individual (even with a rifle) and let me know how it goes. You'd be lucky to live and tell the tale. Humans are the same. Getting the better of an individual human ... so easy it's hardly worth mentioning. Same with the wolf. Doing the same in a group of 100 humans, even a single individual in that group ? You won't survive the attempt.

In all animals strategies work together to establish a desired outcome. Human strength does not come from intelligence, intelligence is simply what allows us to coordinate in large groups. The actual strength comes from the large groups.

And as you likely know, these are dinosaur contemporaries who are from that general lineage. So great example.

"The earliest fossils are from the beginning of the age of dinosaurs, in the late Triassic."

It's been a sad couple of years for people who grew up with Jurassic Park and now realize those scary beasts are just a bunch of mutant chickens.

Reversing back the clock on evolution feels counter productive.

As is getting dentures, but it's more fun turning back the clock that way than not getting dentures (if those teeth are gone.) I vote for fun and discovery. And corn on the cob.

If you imagine finding some big stash of amber with, say, 1 million different dinosaur fragments preserved, you could imagine using some statistical techniques combined with knowledge of extant related species to put something together.
