Hi HN, I built this. It's been posted several times before, so I can answer some common questions: How does this work? I adapted GPlates [1], an academic project that creates desktop software for geologists to investigate plate tectonic data. Is the geocoding accurate? Even though plate tectonic models return precise results, you should consider the plots approximate within ~100km. In my tests I found that model resu…

This is really cool, where is SnowBall earth at ~700M years ago though? https://en.wikipedia.org/wiki/Snowball_Earth

Is the rotation lock when viewing North/South Pole intentional?

I never realized until seeing this 3D globe that literally an entire side of the earth only had water. I've seen drawings of Pangaea before but never in a 3-dimensional sphere. Just interesting to see and entire 1/2 of the earth with nothing but ocean. I wonder how common this is on other planets.

I remember reading about how it's periodic, continents split apart then come together again in a cycle. Not in the same configuration obviously.

one suggestion is that rotation should be disabled by default, disable itself when you manually move the globe, or at least not hidden behind a toggle

otherwise very cool

To be pedantic about it, nearly 3/4 of the earth are still nothing but ocean!

nothing is showing up for me. luckily i already know the answer: bryozoans, bryozoans, and more bryozoans

I also wasn't seeing anything, until I used "⌘ A" to select all text, and noticed that the list of animals or plants for the city I selected was displayed at the top left, in white text over a white background. Selecting all made it slightly more visible, enough for me to read the text. Screenshot: https://i.imgur.com/VQjfvQZ.png

Thanks for the screenshot. There might some weird three.js/webgl thing going on, because that background is supposed to be black with stars. Any errors in the console? Just put out a potential fix.

One of the neat bits from this is going to 340 Mya and look at where the Appalachian mountain range runs. You can hike part of the Appalachian trail in Spain https://www.geologiadesegovia.info/the-international-appalac... and Ireland https://iatulsterireland.com https://en.wikipedia.org/wiki/International_Appalachian_Trai...

The coal fields in the present-day United States, Britain, Spain, France, and Silesia were all once part of the contiguous Appalachian range.

Earlier quoted context omitted.

Well any dinosaur that existed and flew wasn't actually a dinosaur but rather a pterosaur. However I did a quick spot check and realize that modern day birds didn't evolved from pterosaurs but rather from dinosaurs surprised . So I stand corrected.

> Well any dinosaur that existed and flew wasn't actually a dinosaur but rather a pterosaur. I believe you mean: "but rather a pterosaur or bird".

And just to emphasize: This is nitpicky, but it is correct. In the phylogenic sense, birds are dinosaurs. It's not that there used to be dinosaurs, some of which evolved into birds and there are no dinosaurs left anymore, but rather there are about 18000 extant dinosaur species in the world today, it's just that they have feathers and most of them fly.

These are all renderings. Why no photos?

> These are all renderings. Why no photos? Alas! It would seem the Time Travel machine somehow erases the photos during the return trip, so renderings is all they can do.

It's actually a licensing issue, it turns out.

Some what complicated by jurisdictional and statutes of limitations issues.
